Jaskra
Objawy

Jaskra to przewlekła neuropatia nerwu wzrokowego, charakteryzująca się postępującym uszkodzeniem włókien nerwowych i prowadząca do nieodwracalnej utraty wzroku. Najczęstszą postacią jest jaskra pierwotna otwartego kąta, która rozwija się bezobjawowo, co utrudnia wczesne rozpoznanie – nawet do 50% pacjentów nie jest świadomych choroby. Progresja jaskry obejmuje stopniowe zawężanie pola widzenia, widzenie tunelowe oraz utratę widzenia centralnego w zaawansowanych stadiach. Tempo utraty pola widzenia może wynosić od -0,018 do -0,0072 mm²/rok w zakresie nerwowo-siatkówkowym (CSLO) oraz od -0,76 do 1,5 µm/rok w grubości warstwy włókien nerwowych siatkówki (OCT). Czynniki ryzyka szybkiej progresji to m.in. podwyższone i zmienne ciśnienie wewnątrzgałkowe, zaawansowany wiek, cienka rogówka, krwotoki tarczy nerwu wzrokowego oraz predyspozycje genetyczne.

Objawy i cechy charakterystyczne jaskry

Jaskra to grupa chorób oczu, która powoduje postępujące uszkodzenie nerwu wzrokowego, co może prowadzić do nieodwracalnej utraty wzroku, a nawet ślepoty. Jest ona drugą najczęstszą przyczyną ślepoty na świecie. Często nazywana jest „cichym złodziejem wzroku”, ponieważ w najczęstszych postaciach choroba rozwija się bezobjawowo, a pacjent nie zauważa zmian we wzroku aż do momentu, gdy uszkodzenia są już znaczne12.

Wczesne objawy jaskry

W większości przypadków jaskry, zwłaszcza w jaskrze pierwotnej otwartego kąta (najczęstszej postaci), wczesne stadia choroby przebiegają bez widocznych objawów34. Badania pokazują, że nawet do 50% osób z jaskrą nie jest świadomych, że choruje, właśnie z powodu bezobjawowego przebiegu5. Wczesne objawy, jeśli w ogóle występują, mogą obejmować:

  • Stopniową, niezauważalną utratę widzenia obwodowego1
  • Trudności z widzeniem przy zmianie warunków oświetlenia6
  • Niewyraźne widzenie7
  • Trudności z widzeniem w warunkach słabego oświetlenia6

W przeciwieństwie do jaskry otwartego kąta, jaskra zamkniętego kąta może rozwijać się nagle i powodować wyraźne, ostre objawy wymagające natychmiastowej interwencji medycznej8.

Objawy postępującej jaskry

W miarę postępu choroby i zwiększenia uszkodzenia nerwu wzrokowego, pacjenci mogą zacząć doświadczać bardziej zauważalnych objawów9. Do objawów zaawansowanej jaskry należą:

  • Stopniowe powiększanie się ślepych plam w polu widzenia, szczególnie w widzeniu obwodowym19
  • Widzenie tunelowe – utrata bocznego widzenia, zawężające się pole widzenia10
  • Trudności w wykonywaniu codziennych czynności, takich jak czytanie, prowadzenie samochodu czy poruszanie się11
  • Wrażenie widzenia tęczowych kręgów wokół źródeł światła12
  • Nasilające się problemy z ostrością widzenia13

Objawy ostrej jaskry zamkniętego kąta

Ostra jaskra zamkniętego kąta jest stanem nagłym, wymagającym natychmiastowej pomocy medycznej. W przeciwieństwie do jaskry otwartego kąta, ostra jaskra zamkniętego kąta rozwija się nagle i gwałtownie, powodując charakterystyczne, intensywne objawy28:

  • Nagły, intensywny ból oka i/lub głowy14
  • Zaczerwienienie oka8
  • Zamglone lub niewyraźne widzenie15
  • Nudności i wymioty (towarzyszące silnemu bólowi oka)16
  • Widzenie tęczowych obwódek wokół źródeł światła13
  • Nagła utrata wzroku16
  • Rozszerzenie źrenicy niereagujące na światło17

Progresja jaskry i jej wpływ na widzenie

Jaskra jest chorobą postępującą, która bez odpowiedniego leczenia prowadzi do nieodwracalnej utraty wzroku. Tempo progresji może być różne u różnych pacjentów i zależy od wielu czynników, w tym typu jaskry, skuteczności leczenia oraz indywidualnych cech pacjenta918.

Naturalna progresja nieleczonej jaskry

Bez leczenia jaskra prowadzi do stopniowej degradacji wzroku. W przypadku jaskry pierwotnej otwartego kąta, typowa progresja od normalnego widzenia do całkowitej ślepoty może trwać od 10 do 70 lat, w zależności od metody oszacowania518. Badania wskazują, że nieleczona jaskra najczęściej prowadzi do całkowitej ślepoty w ciągu 10-15 lat od momentu pojawienia się pierwszych uszkodzeń5.

Postęp choroby charakteryzuje się następującymi etapami:

  1. Wczesna jaskra: Zmiany w systemie drenażu oka prowadzą do zwiększonego ciśnienia wewnątrzgałkowego. Na tym etapie zazwyczaj nie występują zauważalne objawy19.
  2. Umiarkowana jaskra: Pacjent zaczyna zauważać pierwsze objawy, takie jak plamiste lub niewyraźne widzenie, łagodny lub umiarkowany ból oka19.
  3. Zaawansowana jaskra: Znaczne uszkodzenie nerwu wzrokowego prowadzi do wyraźnego zawężenia pola widzenia i trudności z widzeniem centralnym20.
  4. Końcowe stadium jaskry: Charakteryzuje się znacznym zawężeniem pola widzenia i możliwą całkowitą ślepotą21.

Czynniki ryzyka szybkiej progresji jaskry

Liczne badania kliniczne zidentyfikowały szereg czynników ryzyka związanych z szybszą progresją jaskry22, w tym:

  • Zaawansowany stan choroby w momencie rozpoznania – najważniejszy czynnik ryzyka, obecny we wszystkich głównych badaniach klinicznych22
  • Podwyższone ciśnienie wewnątrzgałkowe22
  • Znaczne wahania ciśnienia wewnątrzgałkowego w ciągu doby22
  • Zaawansowany wiek pacjenta23
  • Zmniejszona grubość rogówki centralnej23
  • Obecność krwotoków tarczy nerwu wzrokowego24
  • Czynniki genetyczne (np. mutacje w genach miocyliny, WDR-36 lub OPTN, polimorfizmy pojedynczych nukleotydów w promotorze genu miocyliny)23
  • Duże strefy atrofii okołotarczowej beta22

Tempo progresji jaskry

Badania pokazują, że szybkość postępu jaskry jest zróżnicowana. Odsetek oczu z jaskrą progresującą szybciej niż -1,5 dB/rok wynosi od 3% do 17% w niektórych badaniach, podczas gdy w innych stwierdzono, że 15-20% oczu wykazuje utratę pola widzenia przekraczającą 5% rocznie25. Liczby te pokrywają się z danymi z wcześniejszych badań, które szacują, że od 6% do 13% pacjentów z jaskrą traci wzrok25.

W przypadku strukturalnych zmian w oku związanych z jaskrą, tempo utraty tkanki nerwowej również zostało zmierzone:

  • Szybkość utraty globalnego obszaru nerwowo-siatkówkowego mierzona za pomocą konfokalnej skaningowej oftalmoskopii laserowej (CSLO) waha się między -0,018 a -0,0072 mm²/rok25
  • Średnie tempo globalnego ścieńczenia warstwy włókien nerwowych siatkówki (RNFL) mierzone za pomocą OCT szacuje się w zakresie od -0,76 do 1,5 µm/rok25

Znaczenie kliniczne progresji jaskry

Klinicznie istotne tempo progresji jaskry to takie, które może prowadzić do upośledzenia funkcjonalnego lub obniżenia jakości życia związanej z widzeniem w przyszłości26. Ocena, czy tempo utraty jest klinicznie istotne, wymaga uwzględnienia trzech czynników26:

  1. Aktualnego stadium (lub ciężkości) choroby
  2. Przewidywanej długości życia pacjenta
  3. Stadium choroby, w którym jakość życia związana z widzeniem mogłaby być dotknięta

Większość leczonych oczu nie postępuje w tempie, które prowadziłoby do przyszłego upośledzenia wzroku, ale istnieje znaczny odsetek (3-17%) oczu, które są zagrożone upośledzeniem nawet pod opieką kliniczną26. Podczas gdy bardzo szybkie tempo progresji (np. progresja MD -1,5 dB/rok) jest generalnie problematyczne, znacznie wolniejsze tempo może być również szkodliwe dla młodych pacjentów, szczególnie tych z późno zdiagnozowaną chorobą26.

Konsekwencje nieleczonej jaskry

Nieleczona jaskra prowadzi do nieodwracalnej utraty wzroku i może skutkować całkowitą ślepotą27. Uszkodzenia spowodowane przez jaskrę powodują12:

  • Postępującą utratę widzenia obwodowego prowadzącą do widzenia tunelowego28
  • W późniejszych stadiach – utratę widzenia centralnego29
  • Trudności w wykonywaniu codziennych czynności, takich jak czytanie i prowadzenie pojazdów30
  • Całkowitą ślepotę w najcięższych przypadkach31

Ważne jest, aby podkreślić, że utrata wzroku spowodowana jaskrą jest nieodwracalna – uszkodzony nerw wzrokowy nie może zostać naprawiony, nawet po przywróceniu normalnego ciśnienia wewnątrzgałkowego32. Dlatego wczesne wykrycie i leczenie są kluczowe dla zachowania wzroku12.

Znaczenie wczesnego wykrycia i leczenia

Wczesne wykrycie i leczenie jaskry ma kluczowe znaczenie dla spowolnienia lub zatrzymania progresji choroby i zapobiegania utracie wzroku33. Badania pokazują, że przy odpowiednim leczeniu większość pacjentów może zachować swoje funkcje wzrokowe9.

Regularne badania okulistyczne są niezbędne do wczesnego wykrycia jaskry, ponieważ większość osób nie zauważa żadnych objawów we wczesnych stadiach choroby34. Badania te powinny być przeprowadzane szczególnie u osób z podwyższonym ryzykiem rozwoju jaskry, takich jak15:

  • Osoby z wysokim ciśnieniem wewnątrzgałkowym
  • Osoby powyżej 40 roku życia
  • Osoby z rodzinnym wywiadem jaskry
  • Osoby z określonymi grupami etnicznymi o wyższym ryzyku
  • Osoby z cukrzycą lub innymi chorobami systemowymi

Leczenie jaskry ma na celu obniżenie ciśnienia wewnątrzgałkowego i ochronę nerwu wzrokowego35. Choć uszkodzenia spowodowane przez jaskrę są nieodwracalne, odpowiednie leczenie może zapobiec dalszej utracie wzroku12.

Monitorowanie progresji jaskry

Monitorowanie progresji jest kluczowym elementem zarządzania pacjentami z jaskrą i osobami podejrzanymi o jaskrę36. Pozwala na ocenę skuteczności leczenia i w razie potrzeby jego modyfikację.

Metody monitorowania progresji

Do monitorowania progresji jaskry wykorzystuje się różne techniki diagnostyczne37:

  • Badanie pola widzenia (perymetria) – umożliwia ocenę funkcjonalną widzenia i wykrycie defektów pola widzenia38
  • Optyczna koherentna tomografia (OCT) – pozwala na pomiar grubości warstwy włókien nerwowych siatkówki i wykrycie strukturalnych zmian w oku39
  • Konfokalna skaningowa oftalmoskopia laserowa (CSLO) – umożliwia ocenę morfologii tarczy nerwu wzrokowego25
  • Regularne pomiary ciśnienia wewnątrzgałkowego40

Do analizy progresji najczęściej używa się badania pola widzenia, które jest uważane za złoty standard w ocenie funkcji wzrokowej38. Jednak analiza może być utrudniona ze względu na zmienność wyników badania pola widzenia, która może wynikać z wielu czynników, takich jak zaćma, zaawansowanie jaskry, efekt uczenia się lub rozproszenie uwagi38.

Ocena tempa progresji

Kluczowym elementem monitorowania jaskry jest określenie tempa progresji (szybkości postępu choroby)41. Głównymi celami są:

  • Identyfikacja szybko postępujących przypadków, które wymagają bardziej intensywnego leczenia41
  • Ocena skuteczności aktualnego leczenia42
  • Dostosowanie celów terapeutycznych do indywidualnych potrzeb pacjenta36

Tempo progresji jest zazwyczaj określane na podstawie analizy serii badań pola widzenia lub pomiarów strukturalnych. Ważne jest, aby ocena progresji uwzględniała wiek pacjenta, jego ogólny stan zdrowia i przewidywaną długość życia36.

Wykorzystanie algorytmów prognostycznych

W ostatnich latach rośnie zainteresowanie wykorzystaniem sztucznej inteligencji (AI) do przewidywania tempa progresji jaskry37. Modele uczenia głębokiego mogą być pomocne w:

  • Ocenie ryzyka szybkiej progresji43
  • Przewidywaniu przyszłych zmian strukturalnych i funkcjonalnych38
  • Identyfikacji pacjentów wymagających intensyfikacji leczenia37

Badania sugerują, że połączenie danych z badania pola widzenia i OCT może pozwolić na dokładniejsze oszacowanie tempa progresji jaskry niż wykorzystanie tylko danych z badania pola widzenia38.

Leczenie i zapobieganie progresji jaskry

Celem leczenia jaskry jest obniżenie ciśnienia wewnątrzgałkowego, co spowalnia postęp choroby i zapobiega dalszej utracie wzroku35. Niestety, uszkodzenia spowodowane przez jaskrę są nieodwracalne, dlatego wczesne wykrycie i leczenie są kluczowe27.

Strategie leczenia w zależności od tempa progresji

Wybór strategii leczenia zależy od wielu czynników, w tym od tempa progresji jaskry44. Pacjenci z szybszą progresją wymagają bardziej intensywnego leczenia i niższego docelowego ciśnienia wewnątrzgałkowego44.

Głównymi metodami leczenia jaskry są45:

  • Krople do oczu – najczęściej stosowana terapia pierwszego rzutu, mająca na celu obniżenie ciśnienia wewnątrzgałkowego46
  • Leczenie laserowe – zabieg ambulatoryjny, który może poprawić odpływ cieczy wodnistej z oka45
  • Zabiegi chirurgiczne – stosowane w przypadkach opornych na leczenie farmakologiczne i laserowe33

W przypadku pacjentów z szybko postępującą jaskrą może być konieczne połączenie różnych metod leczenia lub wcześniejsze zastosowanie metod bardziej inwazyjnych44.

Dostosowanie leczenia w oparciu o monitorowanie progresji

Regularne monitorowanie progresji jaskry pozwala na dostosowanie leczenia do indywidualnych potrzeb pacjenta42. Jeśli wyniki badań wskazują na postęp choroby pomimo leczenia, może być konieczna zmiana strategii terapeutycznej47.

Intensyfikacja leczenia może obejmować44:

  • Dodanie dodatkowego leku obniżającego ciśnienie wewnątrzgałkowe
  • Zastosowanie leczenia laserowego
  • Rozważenie zabiegu chirurgicznego

Badania pokazują, że intensyfikacja leczenia po wystąpieniu krwotoku na tarczy nerwu wzrokowego może spowolnić progresję o średnio -0,50 µm/rok44.

Czynniki wpływające na skuteczność leczenia

Skuteczność leczenia jaskry może być ograniczona przez różne czynniki40:

  • Nieprzestrzeganie zaleceń terapeutycznych przez pacjenta40
  • Wahania dobowe ciśnienia wewnątrzgałkowego40
  • Cienka rogówka, która może dawać fałszywie niskie odczyty ciśnienia wewnątrzgałkowego40
  • Różnice w skuteczności leków w ciągu dnia (różnica między szczytem a minimum działania niektórych leków może wynosić 3-4 mm Hg)40

Regularne monitorowanie ciśnienia wewnątrzgałkowego o różnych porach dnia może pomóc w identyfikacji wahań ciśnienia, które mogą być czynnikiem ryzyka progresji neuropatii jaskrowej40.

Podsumowanie kluczowych aspektów progresji jaskry

Jaskra jest postępującą chorobą nerwu wzrokowego, która bez odpowiedniego leczenia prowadzi do nieodwracalnej utraty wzroku48. Charakterystyczne dla jaskry jest stopniowe uszkadzanie włókien nerwowych, co prowadzi do zwiększania się ślepych pól w widzeniu obwodowym, a w późniejszych stadiach – do utraty widzenia centralnego34.

Najważniejsze aspekty progresji jaskry to22:

  • Większość przypadków jaskry, zwłaszcza jaskry pierwotnej otwartego kąta, rozwija się powoli i bezobjawowo1
  • Tempo progresji jest zróżnicowane – od bardzo powolnej do szybkiej25
  • Zaawansowany stan choroby w momencie rozpoznania jest najważniejszym czynnikiem ryzyka progresji22
  • Regularne monitorowanie jest niezbędne do oceny skuteczności leczenia i wykrycia progresji36
  • Wczesne wykrycie i odpowiednie leczenie mogą zapobiec znacznej utracie wzroku u większości pacjentów49

Mimo że uszkodzenia spowodowane przez jaskrę są nieodwracalne, odpowiednie leczenie mające na celu obniżenie ciśnienia wewnątrzgałkowego może spowolnić lub zatrzymać progresję choroby i zachować pozostałe funkcje wzrokowe33.

  • #1 Glaucoma – Symptoms and causes – Mayo Clinic
    https://www.mayoclinic.org/diseases-conditions/glaucoma/symptoms-causes/syc-20372839
    Usually, fluid called aqueous humor flows freely through the anterior chamber in the eye and exits through the drainage system, known as the trabecular meshwork. If that system is blocked or isn’t functioning well, the pressure inside the eye builds. This pressure can damage the optic nerve. With the most common type of glaucoma, this results in gradual vision loss. […] Many forms of glaucoma have no warning signs. The effect is so gradual that you may not notice a change in vision until the condition is in its later stages. […] The symptoms of glaucoma depend on the type and stage of the condition. […] No symptoms in early stages. Gradually, patchy blind spots in your side vision. Side vision also is called peripheral vision. In later stages, difficulty seeing things in your central vision.
  • #2 Glaucoma: What It Is, Symptoms, Causes, Types & Treatment
    https://my.clevelandclinic.org/health/diseases/4212-glaucoma
    Glaucoma is an umbrella term for eye diseases that make pressure build up inside your eyeball, which can damage delicate, critical parts at the back of your eye. Most of these diseases are progressive, which means they gradually get worse. As they do, they can eventually cause permanent vision loss and blindness. In fact, glaucoma is the second-leading cause of blindness worldwide. […] In its early stages, glaucoma may not cause any symptoms. Thats why up to half of the people in the United States with glaucoma may not know they have it. And symptoms may not appear until this condition causes irreversible damage. […] Some types of glaucoma, particularly angle closure glaucoma, can cause sudden, severe symptoms that need immediate medical attention to prevent permanent vision loss. Emergency glaucoma symptoms include: Blood gathering in front of your iris (hyphema), Bulging or enlarged eyeballs (buphthalmos), Nausea and vomiting that happen with eye pain/pressure, Rainbow-colored halos around lights, Sudden appearance or increase in floaters (myodesopsias), Sudden vision loss of any kind, Suddenly seeing flashing lights (photopsias) in your vision.

    Glaucoma is a leading cause of blindness for people over 60 years old. But blindness from glaucoma can often be prevented with early treatment. […] The optic nerve is made of more than a million tiny nerve fibers. It is like an electric cable made up of many small wires. As these nerve fibers die, you will develop blind spots in your vision. You may not notice these blind spots until most of your optic nerve fibers have died. If all of the fibers die, you will become blind. […] This type of glaucoma is painless and causes no vision changes at first. […] With open-angle glaucoma, there are no warning signs or obvious symptoms in the early stages. As the disease progresses, blind spots develop in your peripheral (side) vision. […] Most people with open-angle glaucoma do not notice any change in their vision until the damage is quite severe. This is why glaucoma is called the silent thief of sight.

    Glaucoma can affect anyone, but some are at a higher risk of developing this eye disease. Because glaucoma presents few early symptoms and doesn’t affect vision or cause pain, it can go unnoticed and undiagnosed. […] By the time you notice symptoms, it’s likely glaucoma has advanced to the point that it’s caused irreparable vision loss. You may notice things like decreased peripheral vision or blurry vision. […] The first symptom of glaucoma is usually gradual peripheral vision loss, which may develop into tunnel vision. It usually does not present symptoms like pain or redness. Those with glaucoma can also experience: […] Open-angle glaucoma progresses without noticeable initial symptoms. It affects nearly 90% of those with glaucoma. Blind spots in your peripheral vision only appear as the disease worsens.
  • #5 How Quickly Does Glaucoma Progress? | Eye Care Professionals
    https://renoeyecare.com/blog/eye-care-professionals/glaucoma-progression/
    About 3 million Americans suffer from glaucoma. This disease is the second most common cause of blindness globally. There are frequently no early signs, which is why 50 percent of patients are unaware of glaucoma progression. […] Glaucoma’s effects are gradual. Untreated glaucoma normally takes between 10 and 15 years from the commencement of initial damage to total blindness. […] The most common type is primary open-angle glaucoma, with age as a factor in its progression. Over the years, the person’s eye drainage system becomes obstructed, causing inadequate fluid outflow from the eye and eventually causing a progressive increase in IOP. […] Rarer than open-angle glaucoma is closed-angle glaucoma. Typically, it grows swiftly. Suddenly, the eye’s drainage region becomes entirely blocked. If left untreated, ocular hypertension can lead to a higher risk of blindness.

    https://www.massgeneralbrigham.org/en/about/newsroom/articles/early-symptoms-of-glaucoma
    Glaucoma is the second leading cause of blindness in the world. People can go years without detecting the condition; they typically experience symptoms only when vision loss becomes permanent. […] Patients rarely notice glaucoma signs and symptoms until it is too late. No current treatments can reverse damage from the condition, let alone vision loss. […] Early symptoms include: Clouded vision, Difficulty seeing when lighting conditions change or in low-light situations. […] In later stages of the disease, patients may experience: Loss of side vision, Damage to central vision. […] A sudden spike in eye pressure can lead to acute and permanent vision loss. This is considered a medical emergency. Symptoms and signs may include: Eye pain, Headaches, Seeing halos around lights, Dilated pupils, Red eyes, Nausea and vomiting.
  • #7 Glaucoma
    https://www.lei.org.au/services/eye-health-information/glaucoma/
    Glaucoma the sneak thief of sight as its commonly called refers to a group of eye diseases which damage your optic nerve causing irreversible vision loss, often without any obvious symptoms. […] When there is significant damage to this nerve, your peripheral (side) vision is lost. Often the loss of peripheral vision goes unnoticed as your central vision remains good. However, the vision loss will gradually extend towards your central vision, until ultimately sight is lost completely. […] Vision loss caused by glaucoma is permanent. […] With open-angle glaucoma, there are no warning signs or obvious symptoms in the early stages and most people dont notice any change in their vision until the damage is quite severe. […] When symptoms do occur, they include: Loss of peripheral vision that gradually creeps towards your central vision, Blurred vision, Difficulty adjusting to low-light conditions.
  • #8 Glaucoma
    https://www.lei.org.au/services/eye-health-information/glaucoma/
    With acute angle-closure glaucoma symptoms include: Sudden onset of severe pain in the eye or forehead, Sudden vision loss, Blurred vision, Redness of the eye, Appearance of rainbow-coloured circles around bright lights, Headache, Nausea, Vomiting. […] If you experience these symptoms, you should contact your ophthalmologist immediately or visit the nearest emergency department, as this is a medical emergency and requires immediate treatment.
  • #9 Stages of Glaucoma: Symptoms, Progression, and Outlook
    https://www.healthline.com/health/eye-health/stages-of-glaucoma
    Glaucoma often doesnt cause noticeable symptoms in the early stages. As the disease progresses, it may cause: blind spots, narrowed vision, blurry vision, low vision. […] Glaucoma is a progressive condition that can lead to complete vision loss if not managed properly. No matter what staging system your doctor uses, a higher stage correlates with a higher degree of vision loss or structural damage. […] With early detection and treatment, glaucoma doesnt cause most peoples vision to change quickly enough to cause noticeable vision loss. It can take many years to decades for glaucoma to cause blindness. […] Advanced glaucoma may cause symptoms such as: vision loss, often starting with peripheral vision, red eyes, blurred vision. […] Most people with glaucoma can maintain their vision with treatment or regular monitoring. About 10% of people have vision loss even with treatment.
  • #10 Glaucoma | Blindness | MedlinePlus
    https://medlineplus.gov/glaucoma.html
    Glaucoma is a group of diseases that can damage the optic nerve of one, or both, of your eyes. This can result in vision loss. […] You may not have any symptoms of glaucoma. Regular eye exams by an eye care provider can check for glaucoma and other eye problems to help protect your vision. Treatments that lower eye pressure help slow the disease. Without treatment, glaucoma can eventually lead to blindness. […] Often there are no symptoms of glaucoma at first. Or symptoms may start so slowly that you may not notice them. Without treatment, you slowly lose your peripheral (side) vision. It may seem like you’re looking through a tunnel. Over time, your straight-ahead vision may decrease until no vision remains. […] If you have sudden symptoms of intense eye pain, blurry vision, red eyes, or an upset stomach (nausea), you need to go to your eye care provider or an emergency room right away. These could be symptoms of angle-closure glaucoma. This less common type of glaucoma causes fluid to build up quickly in your eye.
  • #11 Glaucoma Signs And Symptoms | About Glaucoma | Glaucoma UK
    https://glaucoma.uk/about-glaucoma/signs-symptoms/
    There are several different types of glaucoma. Each type has different signs and symptoms, although the most common type of glaucoma often has no symptoms. […] Most types of glaucoma develop gradually, so in the early stages there are no symptoms. Significant vision can be lost before someone has any signs of glaucoma. […] For people with more advanced glaucoma, daily activities such as reading, driving or moving about become more difficult. […] If you experience these symptoms, you must seek medical advice straight away. […] If you think you or your loved one might have glaucoma, the best thing to do is to book a routine eye test at your local opticians. In fact, glaucoma is often symptomless, so everyone should have an eye test every two years, unless you’ve been told otherwise by your doctor.
  • #12
    https://www.nhs.uk/conditions/glaucoma/
    Glaucoma can lead to loss of vision if it’s not diagnosed and treated early. […] Glaucoma does not usually cause any symptoms to begin with. […] It tends to develop slowly over many years and affects the edges of your vision (peripheral vision) first. […] If you do notice any symptoms, they might include blurred vision, or seeing rainbow-coloured circles around bright lights. […] Very occasionally, glaucoma can develop suddenly and cause: intense eye pain, nausea and vomiting, a red eye, a headache, tenderness around the eyes, seeing rings around lights, blurred vision. […] If you have glaucoma, early diagnosis and treatment can help stop your vision getting worse. […] Without treatment, glaucoma can eventually lead to blindness. […] Glaucoma can usually be detected during a routine eye test at an opticians, often before it causes any noticeable symptoms. […] It’s not possible to reverse any loss of vision that occurred before glaucoma was diagnosed, but treatment can help stop your vision getting worse.
  • #13 Your Guide on Glaucoma in the Eyes
    https://www.healthline.com/health/glaucoma
    As your IOP increases, your optic nerve may become damaged. As damage to your nerve progresses, you may begin losing sight in your eye. […] Primary open-angle glaucoma is the most common type, with no symptoms before gradual vision loss. […] With open-angle glaucoma, the water-like fluid produced in the tissue of your eye near the cornea (aqueous humor) doesn’t drain adequately, leading to a gradual eye pressure increase. This pressure damages the optic nerve and leads to vision loss. […] That vision loss may be so slow that you may not experience any other symptoms or signs of this damage, before that damage becomes permanent and vision loss cannot be restored. […] If you can lower the increased eye pressure to normal levels, vision loss may be slowed or even stopped. […] However, because there’s no cure for glaucoma, you’ll likely need treatment for the rest of your life to regulate your eye pressure levels.
  • #14
    https://www.aao.org/eye-health/diseases/what-is-glaucoma
    People at risk for angle-closure glaucoma usually show no symptoms before an attack. Some early symptoms of an attack may include blurred vision, halos, mild headaches or eye pain. […] An attack of angle-closure glaucoma includes the following: severe pain in the eye or forehead, redness of the eye, decreased vision or blurred vision, seeing rainbows or halos, headache, nausea, vomiting. […] People with „normal tension glaucoma” have eye pressure that is within normal ranges, but show signs of glaucoma, such as blind spots in their field of vision and optic nerve damage. […] Some people have no signs of damage but have higher than normal eye pressure (called ocular hypertension). These patients are considered „glaucoma suspects” and have a higher risk of eventually developing glaucoma.

    https://www.mayoclinic.org/diseases-conditions/glaucoma/symptoms-causes/syc-20372839
    If you have symptoms that come on suddenly, you may have acute angle-closure glaucoma. Symptoms include bad headache and severe eye pain. You need treatment as soon as possible. […] Glaucoma develops when the optic nerve becomes damaged. As this nerve gradually gets worse, blind spots develop in your vision. For reasons that eye doctors don’t fully understand, this nerve damage is usually related to increased pressure in the eye. […] Glaucoma can damage vision before you notice any symptoms. So be aware of these risk factors: High internal eye pressure, also known as intraocular pressure. […] These steps may help find and manage glaucoma in its early stages. That may help to prevent vision loss or slow its progress. Regular eye exams can help find glaucoma in its early stages, before a lot of damage occurs.

    Glaucoma is a group of eye conditions that can damage the optic nerve. This nerve sends the images you see to your brain. […] Most often, optic nerve damage is caused by increased pressure in the eye. This is called intraocular pressure. […] Open-angle glaucoma is the most common type of glaucoma. […] The cause is unknown. The increase in eye pressure happens slowly over time. You cannot feel it. […] The increased pressure pushes on the optic nerve. Damage to the optic nerve causes blind spots in your vision. […] Most people have no symptoms. […] Once you are aware of vision loss, the damage is already severe. […] Slow loss of side (peripheral) vision (also called tunnel vision) is the main type of vision loss. […] Advanced glaucoma can lead to blindness. […] Symptoms may come and go at first, or steadily become worse.

    Narrow-angle glaucoma is much more rare and is very different from open-angle glaucoma in that eye pressure usually goes up very fast. This happens when the drainage canals get blocked or covered over. The iris gets pushed against the lens of the eye, shutting off the drainage angle. Sometimes the lens and the iris stick to each other. This results in pressure increasing suddenly, usually in one eye. There may be a feeling of fullness in the eye along with reddening, swelling and blurred vision. […] The onset of acute narrow-angle glaucoma is typically rapid, constituting an emergency. If not treated promptly, this glaucoma produces blindness in the affected eye in three to five days. Symptoms may include: Inflammation and pain, Pressure over the eye or extreme headache, Moderate pupil dilation thats non-reactive to light, Blurring and decreased visual acuity, Extreme sensitivity to light, Seeing halos around lights, Nausea and/or vomiting. […] Because of the rapid, potentially devastating results of narrow-angle glaucoma, you should consult your eye doctor immediately if you experience any of the above symptoms.

    https://en.wikipedia.org/wiki/Glaucoma
    Vision loss […] Glaucoma may cause vision loss if left untreated. It has been called the „silent thief of sight” because the loss of vision usually occurs slowly over a long period of time. […] Open-angle glaucoma usually presents with no symptoms early in the course of the disease, but it may gradually progress to involve difficulties with vision. […] Acute angle-closure glaucoma, a medical emergency due to the risk of impending permanent vision loss, is characterized by sudden ocular pain, seeing halos around lights, red eye, very high intraocular pressure, nausea and vomiting, and suddenly decreased vision. […] If treated early, slowing or stopping the progression of glaucoma is possible. […] In open-angle glaucoma, the typical progression from normal vision to complete blindness takes about 25 years to 70 years without treatment, depending on the method of estimation used.

    https://responsumhealth.com/conditions/glaucoma/stages-of-glaucoma/
    Like other diseases, glaucoma has multiple stages of progression and severity. Understanding the flow of these stages and the symptoms that characterize them can help make the transition easy as possible, even during the most challenging times. […] The first stage of glaucoma is often exhibited through the onset of mildly intraocular pressure. This stage is generally brought on by changes to the optic nerve and the eyes ability to drain fluid from the trabecular meshwork. Continue working with your physician to monitor your symptoms. […] The second stage of glaucoma is when you or your loved one will start to notice symptoms. These may include patchy or blurry vision or mild to moderate eye pain. […] The third stage of glaucoma can be officially characterized as the advanced stage. Depending upon your level blockage and angle-closure, your doctor may recommend interventions like medications or surgery.

    https://www.voeyedr.com/blog/stages-of-glaucoma/
    Glaucoma progresses gradually, starting with mild vision changes in its early stages and advancing to significant vision loss and potential blindness if left untreated. Early detection and treatment are crucial to slowing its progression and preserving vision. […] Most people don’t notice symptoms until significant vision problems occur. As the disease progresses, blind spots develop in the peripheral vision, eventually leading to severe impairment if untreated. […] In the early stage of glaucoma, symptoms are often minimal or completely absent, making it difficult for people to recognize any changes. Peripheral vision may begin to show subtle changes, and eye pressure might be elevated. […] As glaucoma progresses to the moderate stage, optic nerve damage becomes more apparent – leading to noticeable visual field changes. Symptoms can include tunnel vision – where peripheral vision narrows – or challenges with visual acuity.
  • #21 What are the Different Stages of Glaucoma?

    In advanced glaucoma, significant vision loss occurs, and visual impairment becomes more noticeable. Damage to the optic nerve is extensive, and symptoms often include a severe narrowing of the visual field and difficulty with daily activities that require clear sight. […] The terminal stage of glaucoma is marked by complete or near-total loss of vision. By this point, optic nerve damage is irreversible, and the structural integrity of the eye is compromised.

    https://www.reviewofophthalmology.com/article/glaucoma-staging-and-progression-risk-factors
    When faced with treating a new glaucoma patient, there are two important predictors of patient outcomes to consider. First, one must determine the stage of disease i.e., how advanced the patient’s disease is at the time of presentation. Second, one needs to determine the patient’s risk of progression. […] Although numerous risk factors have been found to be associated with glaucoma progression in different studies, only one has been associated with progression in every major clinical trial: advanced disease at the time of presentation. […] Risk factors for progression are another important determinant when evaluating a patient for glaucoma. They allow us to approximate the likelihood that the patient’s vision will deteriorate in the near future (and long-term). […] Different clinical studies have helped us identify numerous risk factors for glaucoma progression, including elevated IOP, significant diurnal IOP fluctuations, older age, reduced central corneal thickness, the presence of disc hemorrhages, certain genetic factors (for example, mutations in the myocilin, WDR-36 or OPTN genes, or single-nucleotide polymorphisms in the myocilin gene promoter), and a large beta zone of peripapillary atrophy. However, only one risk factor has been found to be statistically significant in every study: advanced disease at the time of presentation.

    Disc hemorrhages are associated not only with OCT and visual field progression (on both 24-2 and 10-2 grids), but also with increased velocity of that progression when compared to glaucoma patients without. It was found that the rate of RNFL progression was faster with post-disc hemorrhages than pre-disc hemorrhages, and intensifying treatment following hemorrhage slowed progression by an average of -0.50m/year. […] A silver lining in the glaucoma progression change the treatment or hold steady? conundrum is that most patients whose disease is identified early in its course and are treated will not experience visual impairment. Nonetheless, rapid progressors are at a much higher risk of impairment than their slower progressing counterparts. […] Therefore, prospectively identifying signs consistent with the risk of rapid glaucomatous progression and then verifying it should lower the threshold for escalating treatment and adopting a more aggressive stance. Intervening with fast progressors is a necessity, but across the board the level of subsequent intervention after a patient has progressed is dependent on many factors, most importantly; current disease stage, rate of past progression, residual field and predicted remaining lifetime.

    The reported proportion of glaucomatous eyes progressing at faster than -1.5 dB/year have varied from 3 to 17% in some previous studies, while others found that 15-20% of eyes seem to progress at rates of VFI loss greater than 5% per year. […] These numbers echo those of a number of older studies estimating the number of patients going blind from glaucoma that range between 6 to 13%. […] However, an irreversible impact on a patients VRQoL could occur even at a much slower rate than this depending on their life expectancy and severity of disease. […] In glaucoma patients, the rates of global neuroretinal rim area loss measured using confocal scanning laser ophthalmoscopy (CSLO) have been found to range between -0.018 and -0.0072 mm2/year while average rates of global SD-OCT based RNFL thinning have been estimated to range between -0.76 and 1.5 m/year.

    Clinically important rates of glaucoma progression (worsening) are ones that put a patient at risk of future functional impairment or reduction of vision-related quality of life. […] Most treated eyes do not progress at rates that will lead to future visual impairment, but there are a significant proportion (3-17%) of eyes, that are at risk of impairment even under clinical care. […] While very fast rates of progression (e.g. MD progression of -1.5 dB/year) are generally problematic, much slower rates also may be deleterious for young patients, particularly those diagnosed with late disease. […] In evaluating whether a rate of loss is clinically important, three factors require consideration: 1) the current stage (or severity) of disease; 2) the life expectancy of the patient; and 3) the severity/stage of disease at which VRQoL would be affected.

    https://www.healthline.com/health/glaucoma
    Glaucoma is an eye disease that can damage optic nerve tissue and result in vision loss. […] Glaucoma is usually, but not always, the result of abnormally high pressure inside the eye. Over time, the increased pressure can erode optic nerve tissue, leading to vision loss or even blindness. […] Many people with glaucoma, especially those with earlier stages of this eye disease, may not experience any symptoms and not recognize they have glaucoma. […] This is true for the most common glaucoma type, open-angle glaucoma. There are no symptoms except for gradual vision loss. […] As this type of glaucoma gets worse, it can lead to increased eye pressure and tunnel vision, or loss of peripheral side vision. […] If these channels are blocked or partially obstructed, the natural pressure increases in your eye (known as intraocular pressure, or IOP).

[…] Increasing eye pressure can lead to irreversible damage to the optic nerve without treatment. […] Both types of glaucoma involve damage to the optic nerve, which can lead to vision loss and blindness. […] Around 10% of people with glaucoma experience some vision impairment. Typically, vision loss from glaucoma first affects a persons peripheral vision. […] As the condition progresses, it may affect their central vision, which a person requires for daily tasks such as driving and reading. […] Without treatment, glaucoma will progress.

    Glaucoma is a group of diseases that can damage the optic nerve of one, or both, of your eyes. This can result in vision loss. […] You may not have any symptoms of glaucoma. Regular eye exams by an eye care provider can check for glaucoma and other eye problems to help protect your vision. Treatments that lower eye pressure help slow the disease. Without treatment, glaucoma can eventually lead to blindness. […] Often there are no symptoms of glaucoma at first. Or symptoms may start so slowly that you may not notice them. Without treatment, you slowly lose your peripheral (side) vision. It may seem like you’re looking through a tunnel. Over time, your straight-ahead vision may decrease until no vision remains. […] If you have sudden symptoms of intense eye pain, blurry vision, red eyes, or an upset stomach (nausea), you need to go to your eye care provider or an emergency room right away. These could be symptoms of angle-closure glaucoma. This less common type of glaucoma causes fluid to build up quickly in your eye.

    Glaucoma impacts millions of people in the world, but many are unaware they have the disease because usually there are no symptoms and most will not notice any vision loss until the disease is at a late stage. […] There are usually no early warning symptoms of glaucoma. Over time, you may slowly lose vision, usually starting with your side (peripheral) vision. Because it happens slowly, you may not notice your vision is changing at first. But as glaucoma progresses, you may experience blurry vision or vision loss. […] Most people who have primary open-angle glaucoma feel fine and do not notice a change in their vision at first because the initial loss of vision is of the side or peripheral vision, and the visual acuity or sharpness of vision is maintained until late in the disease. […] By the time a patient is aware of vision loss, the disease is usually quite advanced. Vision loss from glaucoma is not reversible with treatment, even with surgery.

    For most people with glaucoma, there are no warning signs or noticeable changes in vision until the disease has silently and gradually worsened to a severe stage. […] In the early stages, glaucoma typically affects peripheral (or side) vision. A common misconception is that those with glaucoma get tunnel vision. Tunnel vision is almost never the way patients experience their glaucoma. Instead, vision changes start with a very subtle blurring which usually begins near the nose. Since we see with both eyes at the same time, vision lost in one eye is often covered up and hidden by the other eye. If left untreated, areas of vision loss will slowly spread and may go unnoticed until it reaches the central vision. […] On the other hand, some people may develop acute glaucoma which often presents with severe vision loss and pain that is brought on rather quickly. Symptoms are usually a combination of: Severe eye pain and headache, Blurry vision, Redness of the eyeball, Nausea (upset stomach) or vomiting.

    Glaucoma is a slowly progressing optic neuropathy that may eventually lead to blindness. To help patients receive customized treatment, predicting how quickly the disease will progress is important. […] The progressive glaucomatous damage involves RGC loss in the asymptomatic stages of the disease followed by VF defects at the more advanced stage of glaucoma with significant RGC death. […] Hence, there is a considerable interest to use artificial intelligence (AI) to predict progression rates and facilitate immediate treatment for early-stage glaucoma patients and provide a means to identify rapidly progressing patients who are at high risk of visual disability and may therefore require escalation in treatment.

    The most commonly used functional test of glaucoma is based on standard automated perimetry, which is regarded as the clinical gold standard for assessing visual function. […] However, this assessment is challenging due to VF variability which can be due to several factors like cataracts, the severity of glaucoma with frequent fixation losses, learning effects or distraction. […] AI has also been utilized for predicting glaucoma progression. […] A deep learning model was used to estimate longitudinal changes in RNFL thickness from fundus photographs in order to predict the future development of glaucomatous visual field defects.

[…] Moreover, faster rates of CSLO measured rim area loss and OCT-based RNFL thinning are associated with an increased risk of developing VF damage. […] However, there are challenges in evaluating whether rates of structural progression are clinically significant for a particular patient. […] Estimates of significant mean RNFL rates of loss in healthy eyes of between -0.33 m/year (cross-sectional analysis) and -0.52 m/year (longitudinal analysis) have been reported. […] It is further difficult to reconcile measures of structural loss to what a patient can see as research in this area is scarce. […] Notably, it has been found that RNFL loss is associated with longitudinal reduction in quality of life, even after adjustment for progressive visual field loss. […] Overall, it is important to know the severity of disease that needs to be prevented in order to define what rates of loss are rapid enough to risk future visual impairment and more work needs to be done to achieve this aim.

    A thin cornea can fool us into believing that a patient’s IOP is better controlled than it is. […] Diurnal variation can explain progression in some patients with seemingly well-controlled IOP. […] The patient’s IOP could be 7 mm Hg higher at another time of day. […] If you never check his IOP at any time other than midmorning, you will never discover this pressure fluctuation, which has been shown to be a risk factor for progressive optic neuropathy. […] For some therapeutic agents, the difference between peak and trough efficacy can be as great as 3 to 4 mm Hg, an amount that can make the difference between stability and progression. […] Some patients with apparently well-controlled IOP experience glaucomatous progression. […] With other patients, however, issues such as noncompliance, diurnal fluctuations, and thin corneas can lull us into a false sense of security regarding their IOP control.

    Once the diagnosis of glaucoma is made and there is ultimately a decision to treat it, an entirely new set of decisions arise that can lead to uncertainty for the practitioner and patient alike. Primarily, we need to determine whether our initial intervention is successful or unsuccessful, and can gauge this by seeing if the patient has progressed. If so, what is the rate of progression? […] A major goal in longitudinal glaucoma care is to determine the rate of progression and prioritize fast progressors who are more likely to have a worse prognosis than slow progressors. Keep in mind the course of glaucoma is not always linear, and patients that have historically progressed slowly may change gears and show more rapid advancement of their conditions along the management road. […] Despite having intervened, clinicians should not be surprised or dismayed when further progression occurs. Fortunately, when treated, most eyes will not progress at rates rapid enough to lead to vision loss. Although the majority of patients are not at risk of vision loss, there is still a minority (3% to 17%) that are. […] A recent study examined the relationship between OCT structural measurements, level of average IOP lowering and progression. IOP was shown to significantly impact the rate of global RNFL, isolated ganglion cell layer (GCL) and ganglion cell-inner plexiform layer (GC-IPL) loss, with each additional 1mm Hg mean increase being associated with faster loss of 0.05m/year of RNFL, 0.021m/year GCL and 0.032um/yr of GC-IPL thickness, respectively.

[…] If those test results remain stable over time, the patient is probably at or near a reasonable target IOP. Still, if we watch carefully, most individuals eventually show measurable progression. The doctors task is to limit the amount of glaucomatous change and to minimize the chance of visual disability in the patients expected lifetime. […] State-of-the-art OCT devices are able to detect early glaucomatous progression but frequently miss further loss in areas that have already undergone extensive structural damage.
