Krótkowzroczność
Diagnostyka i diagnoza

Krótkowzroczność (myopia) to wada refrakcji charakteryzująca się wyraźnym widzeniem obiektów bliskich i rozmazanym widzeniem obiektów odległych. Diagnostyka obejmuje wywiad medyczny oraz kompleksowe badanie wzroku, w tym test ostrości wzroku (tablica Snellena), badanie refrakcji, ocenę reakcji źrenic, ruchomości gałek ocznych, widzenia obwodowego, pomiar ciśnienia wewnątrzgałkowego oraz ocenę stanu rogówki, soczewki i powiek. W diagnostyce wykorzystuje się retinoskopię, foropter, autorefraktometrię oraz cykloplegię, szczególnie u dzieci, aby dokładnie określić stopień wady. Krótkowzroczność klasyfikuje się według mocy korekcyjnej w dioptriach (D): łagodna (-0,5 do -3,0 D), umiarkowana (-3,0 do -6,0 D) i wysoka (> -6,0 D). W przypadku patologicznej krótkowzroczności konieczne są zaawansowane badania obrazowe, takie jak angiografia fluoresceinowa (FA), angiografia indocyjaninowa (ICG) oraz optyczna koherentna tomografia (OCT), w celu wykrycia neowaskularyzacji naczyniówkowej i zmian degeneracyjnych na dnie oka.

Diagnostyka i rozpoznanie krótkowzroczności

Krótkowzroczność (myopia) to powszechne zaburzenie refrakcji oka, w którym obiekty znajdujące się w bliskiej odległości są widoczne wyraźnie, natomiast obiekty odległe wydają się rozmazane. Diagnoza krótkowzroczności jest kluczowym elementem w procesie leczenia tej wady wzroku, ponieważ umożliwia wczesną interwencję i wdrożenie odpowiednich metod korekcji.123

Badanie wzroku jako podstawa diagnozy

Podstawowym narzędziem diagnostycznym w rozpoznawaniu krótkowzroczności jest kompleksowe badanie wzroku przeprowadzane przez specjalistę – okulistę lub optometrystę. Proces diagnostyczny zwykle rozpoczyna się od wywiadu medycznego, podczas którego lekarz zbiera informacje na temat historii choroby pacjenta, aktualnych objawów oraz występowania chorób oczu w rodzinie.34

Standardowe badanie wzroku obejmuje kilka kluczowych elementów:

  • Test ostrości wzroku (badanie przy użyciu tablicy Snellena) – pacjent odczytuje z określonej odległości litery lub symbole o różnej wielkości, co pozwala określić, jak dobrze widzi obiekty z różnych odległości56
  • Badanie refrakcji – określa, jak oczy skupiają światło i jaką moc korekcyjną soczewek potrzebuje pacjent78
  • Badanie oceny reakcji źrenic na światło910
  • Badanie ruchomości gałek ocznych1112
  • Ocena widzenia obwodowego (bocznego)1314
  • Pomiar ciśnienia wewnątrzgałkowego1516
  • Badanie stanu rogówki, źrenicy, soczewki i powiek1718

Specjalistyczne metody diagnostyczne

W procesie diagnostyki krótkowzroczności specjaliści korzystają z różnorodnych technik i narzędzi, które pozwalają na dokładną ocenę wady refrakcji:

Retinskopia

Retinskopia to cenna technika stosowana przez specjalistów w diagnostyce krótkowzroczności. W tej procedurze lekarz używa retinskopu do oświetlenia oka, obserwując jednocześnie odbicie światła z siatkówki. Dostosowując soczewki przed okiem, badający może określić wadę refrakcji i obecność krótkowzroczności.192021

Badanie z użyciem foroptery

Foropter to urządzenie diagnostyczne, które umożliwia pacjentowi patrzenie przez różne soczewki, aby określić najlepszą korekcję wzroku. Podczas tego badania pacjent patrzy przez urządzenie wyposażone w różne soczewki i określa, które z nich zapewniają najwyraźniejszy obraz. To badanie pomaga specjaliście ustalić odpowiednią moc soczewek korekcyjnych.222324

Autorefraktometria

Autorefraktometria to nowoczesna metoda diagnostyczna wykorzystująca zautomatyzowane urządzenie do pomiaru wady refrakcji oka. Podczas tego badania pacjent patrzy w wizjer urządzenia, a instrument automatycznie określa moc refrakcyjną potrzebną do uzyskania wyraźnego widzenia. Jest to szybka i dokładna metoda badania krótkowzroczności.2526

Badanie z rozszerzeniem źrenic

Specjalista może również zastosować krople rozszerzające źrenice (cykloplegię), aby dokładniej zbadać stan siatkówki i nerwu wzrokowego. Cykloplegia jest szczególnie ważna w diagnostyce krótkowzroczności u dzieci, ponieważ blokuje naturalną akomodację oka, co pozwala na dokładniejsze określenie wady refrakcji.27282930

Diagnostyka krótkowzroczności u dzieci

Wczesne wykrycie krótkowzroczności u dzieci jest kluczowe dla skutecznego zarządzania jej progresją i zapobiegania poważnym powikłaniom w późniejszym życiu. Badanie wzroku u dzieci obejmuje specyficzne elementy, które uwzględniają ich wiek i zdolność do współpracy:313233

  • U dzieci zbyt małych, aby przeczytać litery na tablicy, okuliści mogą używać retinskopu do pomiaru, gdzie światło jest kierowane wewnątrz oka, co pozwala na określenie wady refrakcji34
  • Badanie obejmuje również ocenę regularności odruchu świetlnego i ocenę stanu zdrowia oczu dziecka35
  • Cykloplegia (krople rozszerzające źrenice) jest często stosowana u dzieci, aby uzyskać dokładny pomiar refrakcji poprzez zredukowanie skurczu mięśni oka, co jest naturalnym zjawiskiem u dzieci i może powodować, że skupiają się one bardziej na obiektach bliskich niż odległych36

American Academy of Ophthalmology zaleca regularne badania przesiewowe wzroku, aby zapewnić wczesną diagnozę i leczenie krótkowzroczności.37 Zalecany harmonogram badań wzroku dla wszystkich dzieci obejmuje:

  • Pierwsze badanie wzroku w wieku 6 miesięcy38
  • Badanie przesiewowe w szkole lub u pediatry, które może wykryć krótkowzroczność3940
  • Regularne badania wzroku, szczególnie dla dzieci z grup ryzyka (np. z rodzinnym występowaniem krótkowzroczności)41

Ocena stopnia krótkowzroczności

W wyniku badania wzroku pacjentowi z krótkowzrocznością przepisywana jest recepta na okulary lub soczewki kontaktowe, która określa, jakie soczewki są potrzebne do poprawy wzroku. Stopień krótkowzroczności mierzony jest w dioptriach (D), a recepta ma wartość ujemną.424344

Krótkowzroczność można sklasyfikować na podstawie jej nasilenia:

  • Łagodna krótkowzroczność: od -0,5 D do -3,0 D4546
  • Umiarkowana krótkowzroczność: od -3,0 D do -6,0 D4748
  • Wysoka krótkowzroczność: powyżej -6,0 D495051

Im wyższa wartość bezwzględna dioptrii, tym silniejsze będą soczewki korekcyjne.52

Diagnostyka patologicznej krótkowzroczności

Patologiczna krótkowzroczność (degeneracyjna) to poważniejsza forma krótkowzroczności, która wiąże się z degeneracyjnymi zmianami na dnie oka i może prowadzić do trwałego upośledzenia widzenia. Diagnoza patologicznej krótkowzroczności wymaga bardziej zaawansowanych badań:535455

  • Angiografia fluoresceinowa (FA) jest przydatna w ocenie pacjentów z krótkowzrocznością pod kątem rozwoju neowaskularyzacji naczyniówkowej (CNV). Wczesne obrazy mogą pokazać defekty transmisji w plamkach lub obszarach atrofii nabłonka barwnikowego siatkówki (RPE) w plamce żółtej i/lub wokół tarczy nerwu wzrokowego.56
  • Angiografia indocyjaninowa (ICG) może być bardziej czuła w wykrywaniu CNV, ponieważ przeciek naczyniowy w patologicznej krótkowzroczności jest zwykle mniej wyraźny niż w przypadku patologii związanych z AMD i może być łatwiej przeoczony w angiografii fluoresceinowej.57
  • Optyczna koherentna tomografia (OCT) jest preferowaną metodą śledzenia myopicznej CNV w czasie. Chociaż FA lub angiografia ICG są bardziej czułe w wykrywaniu, SD-OCT jest nieinwazyjną, mierzalną i szeroko dostępną metodą monitorowania CNV.5859

Diagnoza patologicznej krótkowzroczności opiera się na badaniu dna oka z identyfikacją charakterystycznych cech, braku bardziej prawdopodobnej przyczyny degeneracji i testach diagnostycznych opisanych powyżej.60

Nowoczesne techniki diagnostyczne

W ostatnich latach nastąpił znaczący postęp w diagnostyce krótkowzroczności, wprowadzając nowe technologie i metody, które umożliwiają bardziej precyzyjną ocenę i monitorowanie tej wady wzroku.6162

Pomiar długości osiowej oka

Pomiar długości osiowej oka (długości przednio-tylnej gałki ocznej) jest uznawany za złoty standard w monitorowaniu kontroli krótkowzroczności.63 Badania wykazały, że długość osiowa oka jest lepszym wskaźnikiem ryzyka rozwoju patologii siatkówki niż stopień krótkowzroczności wyrażony w dioptriach.64

  • Długość osiowa oka wynosząca 26 mm jest uważana za wartość graniczną, przy której ryzyko upośledzenia widzenia znacznie wzrasta. Przy długości osiowej większej niż 26 mm istnieje 25% szans na trwałą utratę wzroku.65
  • Ryzyko trwałej utraty wzroku w oku o długości osiowej większej niż 30 mm wynosi 90%, a 3,8% jeśli oko jest krótsze niż 26 mm.66

Pomiar długości osiowej oka jest istotnym elementem kontroli krótkowzroczności. Mierzenie długości oka w praktyce klinicznej może znacznie pomóc w ustaleniu profilu ryzyka. Pozwala również na dokładne monitorowanie progresji krótkowzroczności u młodych pacjentów i dostosowanie strategii zarządzania i opcji leczenia dla każdego dziecka.67

Myopia Master

Myopia Master to narzędzie diagnostyczne, które łączy trzy istotne badania w jednym systemie. Mierzy długość osiową, krzywiznę rogówki i błąd refrakcji. Są to kluczowe wskaźniki przy ocenie krótkowzroczności.68

Komputerowe systemy diagnostyczne

Rozwój algorytmów obrazowania siatkówki i systemów diagnostyki wspomaganej komputerowo do automatycznego wykrywania patologicznej krótkowzroczności z obrazów dna siatkówki budzi obecnie duże zainteresowanie w środowisku naukowym.69

Aktualna praktyka kliniczna w wykrywaniu patologicznej krótkowzroczności jest w dużej mierze zależna od ręcznych wysiłków przesiewowych badającego; dlatego kompleksowe badanie oka może trwać do 60 minut.70 Nowe technologie oparte na sztucznej inteligencji mogą pomóc w opracowaniu nieinwazyjnych metod diagnostyki krótkowzroczności, na przykład na podstawie zdjęć dna oka, które nie wymagałyby cykloplegii i umożliwiałyby przeprowadzenie masowych projektów przesiewowych.71

Znaczenie wczesnej diagnostyki

Wczesne wykrycie i interwencja są kluczowe w spowolnieniu progresji krótkowzroczności. Wiele dzieci z krótkowzrocznością nie będzie miało oczywistych objawów i nie będzie zgłaszało dolegliwości.7273

Korzyści wczesnej diagnostyki

Wczesna diagnoza krótkowzroczności przynosi liczne korzyści:

  • Umożliwia wczesną interwencję, co może pomóc spowolnić progresję krótkowzroczności7475
  • Pozwala na wdrożenie metod kontroli krótkowzroczności, które mogą zmniejszyć ryzyko rozwoju wysokiej krótkowzroczności76
  • Redukuje negatywny wpływ słabego wzroku na rozwój społeczny i akademicki dziecka77
  • Może zapobiec powikłaniom związanym z krótkowzrocznością, takim jak odwarstwienie siatkówki, jaskra, zaćma czy zwyrodnienie plamki żółtej7879

Progresja krótkowzroczności

Krótkowzroczność zwykle rozwija się w dzieciństwie, najczęściej między 5. a 14. rokiem życia, i stopniowo pogarsza się do wczesnej dorosłości, kiedy to wzrok zwykle stabilizuje się.8081 Wczesna interwencja jest kluczowa, ponieważ krótkowzroczność postępuje szybciej u młodszych dzieci, które szybko rosną i rozwijają się.82

Regularne badania wzroku są niezbędne dla osób z krótkowzrocznością, aby monitorować jej stopień. Jeśli krótkowzroczność postępuje, wczesne interwencje są kluczowe. Bardzo ważne jest spowolnienie progresji krótkowzroczności, zanim rozwinie się wysoka krótkowzroczność.83

Grupy ryzyka

Szczególną uwagę należy zwrócić na diagnostykę krótkowzroczności w grupach ryzyka:

  • Dzieci, których rodzice mają krótkowzroczność8485
  • Dzieci spędzające mało czasu na świeżym powietrzu8687
  • Dzieci spędzające dużo czasu na pracy wzrokowej z bliska (czytanie, korzystanie z urządzeń elektronicznych)8889
  • Wcześniaki, które są narażone na krótkowzroczność, amblyopię i zeza90

Różnicowanie diagnozy

Podczas diagnostyki krótkowzroczności ważne jest różnicowanie jej od innych wad refrakcji i chorób oczu. Główne wady refrakcji to:91

  • Krótkowzroczność (myopia) – obiekty odległe wydają się rozmazane, a obiekty znajdujące się blisko są widoczne wyraźnie92
  • Nadwzroczność (hyperopia/hypermetropia) – trudności z widzeniem obiektów znajdujących się blisko, podczas gdy obiekty odległe są widoczne wyraźniej93
  • Astygmatyzm – nieregularny kształt rogówki powoduje zniekształcenie widzenia94
  • Starczowzroczność (presbyopia) – niezdolność do skupiania wzroku na obiektach znajdujących się blisko, związana z wiekiem95

Zrozumienie różnic między tymi wadami refrakcji jest kluczowe dla właściwej diagnozy i leczenia.96

Znaczenie regularnych badań kontrolnych

Regularne badania wzroku są ważne dla wszystkich, ale są szczególnie istotne dla osób z wysoką krótkowzrocznością lub krótkowzrocznością patologiczną.9798

Zalecany harmonogram badań kontrolnych:

  • Dzieci z krótkowzrocznością powinny mieć badania wzroku co 6-12 miesięcy99
  • Dorośli i dzieci ze zdiagnozowaną krótkowzrocznością potrzebują regularnych badań wzroku, aby sprawdzić stopień krótkowzroczności100
  • Osoby z wysoką lub patologiczną krótkowzrocznością powinny mieć częstsze badania kontrolne101
  • Okresowe przeglądy – zwykle co 6 miesięcy lub według innych zaleceń102

Regularne badania wzroku są niezbędne do wykrywania i skutecznego zarządzania krótkowzrocznością. Wczesne wykrycie krótkowzroczności umożliwia terminową interwencję i odpowiednie środki korekcyjne, pomagając osobom cieszyć się wyraźnym widzeniem i utrzymać optymalne zdrowie oczu.103

Podsumowanie procesu diagnostycznego

Diagnoza krótkowzroczności jest kluczowym krokiem w zarządzaniu tym powszechnym problemem ze wzrokiem. Testy ostrości wzroku, retinskopia i autorefraktometria są podstawowymi metodami stosowanymi przez specjalistów w zakresie ochrony wzroku do dokładnej diagnozy krótkowzroczności.104

Kompleksowy proces diagnostyczny krótkowzroczności obejmuje:

  1. Wywiad medyczny i ocenę objawów105106
  2. Badanie ostrości wzroku (tablica Snellena)107108
  3. Retinskopię lub badanie za pomocą foroptery109110
  4. Autorefraktometrię (w miarę dostępności)111
  5. Badanie z rozszerzeniem źrenic (w razie potrzeby)112113
  6. Ocenę stanu siatkówki i nerwu wzrokowego114
  7. Pomiar długości osiowej oka (szczególnie w przypadku postępującej lub wysokiej krótkowzroczności)115116
  8. Dodatkowe badania obrazowe (OCT, angiografia) w przypadku podejrzenia patologicznej krótkowzroczności117118

Wczesne wykrycie i odpowiednie zarządzanie krótkowzrocznością jest kluczowe dla utrzymania dobrego widzenia i zapobiegania potencjalnym powikłaniom związanym z tą wadą wzroku. Regularne badania wzroku odgrywają kluczową rolę w identyfikacji i skutecznym zarządzaniu krótkowzrocznością.119120

[…] This refractive defect poses a risk to vision as it can lead to more severe visual pathologies. […] High myopia can favor progressive retinal and choroidal atrophy, vitreous degeneration, optic nerve alterations, retinal hemorrhages and even macular holes. […] In principle, there is no specific treatment for high myopia and, in any case, an individual assessment of each patient should be made to establish the guidelines to be followed.

    Is it hard to see distant objects, like highway signs, until you’re a few feet away, but easy to read a book up close? Chances are you have myopia, also known as nearsightedness. […] An eye doctor will perform an eye exam to see you have myopia. […] An eye exam can show you if you have myopia. Glasses, contacts, or refractive surgery can usually correct the problem. […] Your doctor will have you stand at a specific distance from an eye chart called a Snellen chart. This chart has rows of letters or symbols that gradually get smaller down the chart. […] A phoropter test is a similar exam that has you look through a device with different lenses until you can see symbols or letters clearly. This helps your doctor know which prescription you need to correct your vision. […] When you have myopia, your prescription for glasses or contact lenses will be a negative number. The more negative the number, the stronger your lenses will be. […] Myopia doesn’t have a cure, but the treatments for it are very effective and in many cases can restore your vision to 20/20. […] Regular vision screenings can help catch this condition early so you can treat it.

    Myopia, also known as being short sighted, causes your vision to be blurry in the distance but clearer when looking at things up close. […] Myopia is a very common focusing problem, and for most people it can be easily corrected using glasses or contact lenses to make vision clear and crisp. […] Pathological myopia means that you are very short sighted and that this has caused degenerative changes to the back of your eye. Pathological myopia can cause a reduction in your sight that cannot be corrected with glasses or contact lenses. […] In people with myopia, the light entering the eye comes to a focus point before it reaches your retina. This makes vision blurry and is caused by the eyeball being too long or the cornea being more steeply curved. […] People with myopia require a prescription for glasses or contact lenses with a minus lens power to correct their vision.

    Most people with myopia of less than -6.00D dont develop any further problems. This is sometimes known as simple myopia, meaning that your eyes are healthy and that the blurriness that your myopia causes is easily corrected for with glasses or contact lenses. […] If youve been diagnosed with pathological or degenerative myopia, you have very high myopia, and your eye also shows degenerative changes affecting the back of the eye (the retina). […] The type of treatment you may need will depend upon the degenerative change that has developed. Unfortunately, not all the changes that happen in pathological myopia, such as retinal atrophy and lacquer cracks, can be treated. […] If you already have high myopia, there are no treatments available to stop your eye from developing the complications of high or pathological myopia.

    Pathologic myopia represents a subgroup of myopia and affects up to 3% of the world population. Vision loss related to pathologic myopia is of great clinical significance as it can be progressive and irreversible and affects individuals during their most productive years. High myopia is defined as refractive error of at least -6.00 D or an axial length of 26.5 mm or more. […] Diagnosis is based on fundus examination with identification of characteristic features, lack of more plausible cause for the degeneration, and diagnostic testing as described below. […] Fluorescein angiography (FA) is useful for evaluating myopic patients for development of CNV. Early images may show transmission defects in patches or areas of RPE atrophy in the macula and/or around the optic disc. […] Indocyanine green (ICG) angiography may be more sensitive for detecting CNV as the vascular leakage in pathologic myopia is typically less prominent than for AMD-related pathology and can be more easily missed on fluorescein angiography.

[…] Researchers and developers of diagnostic technologies should design improved patient tests to better understand the myopic eye, its development, and the effects of the visual diet. […] The report notes that most research on myopia comes from international studies, with limited evidence available in the United States due to a lack of standardized definitions of myopia, irregular and inconsistent screening practices, and the use of varied assessment techniques. There is no consensus for mandatory assessment and diagnostic components of a clinical examination of myopia patients. Diagnostic biomarkers are under development that may improve identification, prognosis, and aid in customized management of myopia.

    It is now understood that prescription (the refraction and power of your glasses) and eyeball length (axial length) are not necessarily proportional; for a low myopic refraction may have a high axial length, and vice versa. This is why measuring the length of the eye, in addition to determining the refraction during the consultation is so important. […] Measuring axial length is a vital component of myopia control. Measuring the eye length in clinical practice can greatly assist with establishing a risk profile.

    Refraction is the “clearer 1 or clearer 2” game that optometrists have played with patients for decades. It’s the art of determining the prescription for each eye based on the information we have available. […] Historically, it was believed that becoming more than -6.00D short sighted increased the risk of developing retinal pathology. It was then discovered that even low levels of shortsightedness have an increased risk of eye conditions affecting the retinal health. This turned the attention towards axial length as the predictor of retinal risk. […] The length of the eyeball (or axial length) is the gold standard of monitoring myopia control. […] Axial length of 26mm is considered a defining number in the literature, whereby risk of visual impairment is considerably increased. If the axial length is more than 26mm, there is a 25% chance of permanent vision loss.

[…] Diagnosis is based on fundus examination with identification of characteristic features, lack of more plausible cause for the degeneration, and diagnostic testing as described below. […] Fluorescein angiography (FA) is useful for evaluating myopic patients for development of CNV. Early images may show transmission defects in patches or areas of RPE atrophy in the macula and/or around the optic disc. […] Indocyanine green (ICG) angiography may be more sensitive for detecting CNV as the vascular leakage in pathologic myopia is typically less prominent than for AMD-related pathology and can be more easily missed on fluorescein angiography. […] Spectral-domain OCT (SD-OCT) has been the preferred method of following myopic CNV over time. Although FA or ICG angiography is more sensitive for detection, SD-OCT is a noninvasive, quantifiable, and widely available method for monitoring CNV.

    If you have high myopia (severe short-sightedness), usually over 600 degrees, you may be at risk of developing complications in the macula (the part of the retina used for central vision), which are often termed „myopic maculopathy” or „pathologic myopia”. […] Myopic maculopathy is diagnosed by careful dilated eye examination by an ophthalmologist. Examination is usually supplemented by detailed imaging such as optical coherence tomography (OCT) scans, geared toward assessing for thinning of the retina as well as other layers of the eye, such as the choroid and sclera.

    Is it hard to see distant objects, like highway signs, until you’re a few feet away, but easy to read a book up close? Chances are you have myopia, also known as nearsightedness. […] An eye doctor will perform an eye exam to see you have myopia. […] An eye exam can show you if you have myopia. Glasses, contacts, or refractive surgery can usually correct the problem. […] Your doctor will have you stand at a specific distance from an eye chart called a Snellen chart. This chart has rows of letters or symbols that gradually get smaller down the chart. […] A phoropter test is a similar exam that has you look through a device with different lenses until you can see symbols or letters clearly. This helps your doctor know which prescription you need to correct your vision. […] When you have myopia, your prescription for glasses or contact lenses will be a negative number. The more negative the number, the stronger your lenses will be. […] Myopia doesn’t have a cure, but the treatments for it are very effective and in many cases can restore your vision to 20/20. […] Regular vision screenings can help catch this condition early so you can treat it.

    Corneal reshaping therapy, also known as orthokeratology, involves using specific lenses to temporarily change the shape of the cornea. […] A 2019 review of articles suggests that this therapy may help correct myopia and prevent it from progressing. […] Eye doctors may use low-dose atropine to help slow down the progression of myopia in children. […] The long-term outlook for people with myopia is good. Myopia can worsen from childhood until your 20s. However, most people with nearsightedness see great improvement with treatment, including corrective lenses or surgery. […] Treating myopia early in childhood can help prevent the progression of myopia as well as any social and academic impact of poor eyesight. […] Certain treatments, including bifocals, contact lenses, corneal reshaping therapy, and eye drops, may help prevent nearsightedness from progressing.
