Jaskra
Epidemiologia

Jaskra, będąca drugą najczęstszą przyczyną nieodwracalnej ślepoty na świecie, dotyka około 57,5 miliona osób z pierwotną jaskrą otwartego kąta (PJOK), a jej globalna częstość wynosi 2,2%. Prognozy wskazują na wzrost liczby chorych do 111,8 miliona do 2040 roku. W USA w 2022 roku jaskrą cierpiało około 4,22 miliona osób, z czego 1,5 miliona miało jaskrę wpływającą na widzenie. Epidemiologia jaskry wykazuje znaczne zróżnicowanie etniczne i geograficzne: częstość PJOK w populacjach białych wynosi 0,3-4,0%, azjatyckich 0,5-2,6%, latynoskich 2,0%, a w populacji czarnoskórej 2,9-8,8%, z ryzykiem rozwoju jaskry 3-6 razy wyższym niż u osób białych. Wiek jest kluczowym czynnikiem ryzyka – częstość PJOK wzrasta z 0,7% w wieku 40 lat do 7,7% powyżej 80 lat, a kobiety wykazują wyższe wskaźniki chorobowości niż mężczyźni (1,36% vs. 1,17%). Pierwotna jaskra zamkniętego kąta (PJZK) stanowi znaczący odsetek przypadków, szczególnie w populacjach Inuitów, gdzie jej częstość jest 20-40 razy wyższa niż u osób białych.

Epidemiologia jaskry na świecie

Jaskra stanowi jeden z najważniejszych problemów zdrowia publicznego na świecie, będąc drugą po zaćmie przyczyną nieodwracalnej ślepoty. Szacuje się, że na świecie około 57,5 miliona osób cierpi na pierwotną jaskrę otwartego kąta (PJOK), a globalna częstość występowania tej choroby wynosi 2,2%1. Do 2020 roku przewidywano, że około 76 milionów osób będzie cierpieć na jaskrę, a liczba ta ma wzrosnąć do 111,8 miliona do 2040 roku12. Najnowsze dane wskazują, że w 2022 roku w Stanach Zjednoczonych około 4,22 miliona osób cierpiało na jaskrę, w tym 1,5 miliona osób z jaskrą wpływającą na widzenie3.

Według danych Światowej Organizacji Zdrowia (WHO) z 2002 roku, jaskra przesunęła się z trzeciego na drugie miejsce na liście głównych przyczyn ślepoty na świecie4. Szacunkowo 12,3% spośród 37 milionów niewidomych na świecie straciło wzrok z powodu jaskry4. W 2010 roku, około 8,4 miliona osób na świecie było niewidomych z powodu pierwotnej jaskry otwartego kąta, a do 2040 roku szacuje się, że liczba ta wzrośnie do 22 milionów5.

Warto podkreślić, że jaskra często rozwija się bezobjawowo, co sprawia, że nawet 50% osób dotkniętych tą chorobą nie jest świadomych swojego stanu6. W niektórych krajach rozwijających się, nawet 90% przypadków jaskry pozostaje niezdiagnozowanych7. W samych Stanach Zjednoczonych co najmniej 2,25 miliona osób powyżej 40. roku życia ma jaskrę, ale tylko połowa z nich jest tego świadoma i poddaje się leczeniu8.

Różnice geograficzne i etniczne

Częstość występowania jaskry różni się znacząco w zależności od regionu geograficznego i pochodzenia etnicznego. W populacjach białych, pierwotna jaskra otwartego kąta występuje u 0,3-4,0% starszej populacji, w populacjach azjatyckich u 0,5-2,6%, a w populacji latynoskiej w Stanach Zjednoczonych u 2,0%9. W populacjach czarnoskórych częstość występowania PJOK jest wyższa i waha się od 2,9 do 8,8% starszej populacji9.

Badania wykazały, że osoby pochodzenia afrykańskiego mają około 3-6 razy wyższe ryzyko rozwoju jaskry niż osoby białe1011. Czarnoskóre osoby nie tylko 4-8 razy częściej tracą wzrok z powodu jaskry, ale także ślepną 8 razy szybciej11. Wśród osób w wieku 46-65 lat, prawdopodobieństwo ślepoty z powodu PJOK jest 15 razy wyższe wśród czarnoskórych niż wśród białych12.

W Europie, najwyższą częstość występowania jaskry wśród krajów UE-4 i Wielkiej Brytanii odnotowano w Niemczech (0,7 miliona przypadków), a następnie we Francji i we Włoszech (dane z 2023 roku)13. W Japonii odnotowano około 1,6 miliona zdiagnozowanych przypadków jaskry w 2023 roku13.

Ponadto, częstość występowania pierwotnej jaskry zamkniętego kąta (PJZK) również różni się znacząco między grupami etnicznymi. W populacjach kaukaskich w Stanach Zjednoczonych i Europie częstość występowania PJZK szacuje się na 0,1%12. Populacje Inuitów z regionów arktycznych mają najwyższą znaną częstość występowania PJZK, około 20-40 razy wyższą niż u osób białych12.

Wpływ wieku i płci

Ryzyko rozwoju jaskry zwiększa się znacząco wraz z wiekiem. Częstość występowania PJOK zwiększa się z 0,7% w wieku 40 lat do 7,7% dla osób powyżej 80 lat14. W raporcie samooceny z National Health Interview Survey stwierdzono, że częstość występowania jaskry wzrasta z 0,2% w wieku 18 lat do ponad 10,7% dla osób powyżej 75 lat14.

Osoby znajdujące się w grupie najwyższego ryzyka to te w wieku 70 lat lub starsze (częstość występowania specyficzna dla wieku wynosi 58,7 na 100 000 osób rocznie)15. Badania Rotterdam i Barbados wykazały znaczący wzrost częstości występowania jaskry u starszych osób, przy czym osoby w wieku 70 lat mają generalnie 3-8 razy wyższe ryzyko niż osoby w wieku 40 lat12.

Jeśli chodzi o płeć, kobiety mają wyższe wskaźniki chorobowości niż mężczyźni zarówno dla jaskry (1,36% vs. 1,17%), jak i jaskry wpływającej na widzenie (0,48% vs. 0,41%)3. Kobiety mają również 3,8 razy wyższe ryzyko wystąpienia ostrej pierwotnej jaskry zamkniętego kąta w porównaniu z mężczyznami15.

Globalne obciążenie chorobą

Obciążenie ekonomiczne związane z jaskrą jest znaczące. W Stanach Zjednoczonych szacunkowy koszt leczenia i zapobiegania jaskrze wynosi około 5,8 miliarda dolarów rocznie, a przewiduje się, że roczny koszt medyczny jaskry może wynieść nawet 12 miliardów dolarów do 2032 roku i 17,3 miliarda dolarów do 2050 roku16. Bezpośrednie koszty i straty produktywności wynikające z jaskry wynoszą 2,86 miliarda dolarów rocznie dla amerykańskiej gospodarki617.

W badaniu Global Burden of Disease 2019 oszacowano, że globalna liczba przypadków jaskry wzrosła z 3 881 624 w 1990 roku do 7 473 400 w 2019 roku, podczas gdy standaryzowany wiekowo wskaźnik chorobowości zmniejszył się ze 111,92 w 1990 roku do 94,68 w 2019 roku18. Liczba lat życia skorygowanych niesprawnością (DALY) z powodu jaskry wzrosła z 442 182 w 1990 roku do 748 308 w 2019 roku18.

Należy również podkreślić, że najwyższe obciążenie jaskrą odnotowano w regionach o niskim wskaźniku społeczno-demograficznym (SDI), które wymagają większej uwagi w zakresie wczesnej diagnostyki i leczenia18. Zaobserwowano istotną negatywną korelację między wskaźnikiem społeczno-demograficznym a standaryzowanymi wiekowo wskaźnikami DALY18.

Jaskra jako globalny problem zdrowia publicznego

Wysoka częstość występowania i wysoki wskaźnik ślepoty czynią z jaskry problem zdrowia publicznego i priorytet wśród planistów opieki zdrowotnej i decydentów politycznych, z naciskiem na potrzebę ścieżek opieki nad jaskrą dla wczesnego wykrywania i leczenia w celu zapobiegania ślepocie16.

Jaskra jest najczęstszą przyczyną możliwej do uniknięcia, nieodwracalnej ślepoty na świecie. W Stanach Zjednoczonych jaskra dotyka ponad 2,2 miliona osób i jest drugą wiodącą przyczyną ślepoty u dorosłych powyżej 40. roku życia (pierwszą jest zwyrodnienie plamki żółtej)9.

Co więcej, badania wykazują, że jaskra jest bardziej powszechna wśród starszych osób, przy czym osoby w wieku 70 lat mają 3-8 razy wyższą częstość występowania PJOK niż osoby młodsze19. Wraz ze starzeniem się populacji całkowita liczba pacjentów z jaskrą będzie nadal rosnąć19.

Różnice w typach jaskry

Jaskra to grupa chorób o zróżnicowanej etiologii, przy czym główne typy to jaskra otwartego kąta (JOK) i jaskra zamkniętego kąta (JZK). Pierwotna jaskra otwartego kąta (PJOK) stanowi większość przypadków jaskry na świecie20.

Jednakże epidemiologia PJZK jest mniej zbadana niż epidemiologia jaskry otwartego kąta, choć nie jest mniej ważna. W rzeczywistości PJZK może stanowić 64% wszystkich przypadków jaskry w Mongolii i 50% wszystkich przypadków jaskry na świecie21. PJZK odpowiada za połowę wszystkich przypadków ślepoty związanej z jaskrą20.

Ślepota może wystąpić zarówno w jaskrze zamkniętego kąta, jak i otwartego kąta. W rzeczywistości wskaźnik ślepoty z powodu jaskry zamkniętego kąta może być nawet wyższy niż w przypadku jaskry otwartego kąta21.

Różnice w rozpowszechnieniu różnych typów jaskry

Według badania przeprowadzonego w siedmiu głównych rynkach (7MM: USA, Francja, Niemcy, Włochy, Hiszpania, Wielka Brytania i Japonia), w 2020 roku było 4 190 943 zdiagnozowanych nowych przypadków pierwotnej jaskry otwartego kąta (PJOK) z wyłączeniem jaskry normalnego ciśnienia (NTG)22. Zdiagnozowane nowe przypadki jaskry będą wykazywać roczny wskaźnik wzrostu (AGR) przekraczający 1% w latach 2023-203322.

W 7MM kraje te miały 7 289 907 całkowitych przypadków PJOK w 2020 roku, a przewiduje się, że liczba ta wzrośnie do 8 835 233 przypadków do 2030 roku, przy rocznym wskaźniku wzrostu (AGR) wynoszącym 2,12%23. Przypadki PJZK w 7MM wzrosną z 1 781 968 w 2020 roku do 2 065 644 w 2030 roku, przy AGR wynoszącym 1,59%23.

Model epidemiologiczny jaskry klasyfikuje jaskrę otwartego kąta na podtypy w oparciu o różne cechy kliniczne. W 2023 roku było około 2 milionów przypadków pierwotnej jaskry otwartego kąta (PJOK), 0,8 miliona przypadków jaskry normalnego ciśnienia (NTG) i 0,2 miliona przypadków wtórnej jaskry otwartego kąta (WJOK)13.

Warto podkreślić, że PJOK jest dominującym podtypem klinicznym jaskry na wszystkich analizowanych rynkach24. Ponadto szacuje się, że całkowita populacja PJOK na świecie wynosi około 68,56 miliona w 2020 roku, a ponad 53% z nich znajduje się w Azji25.

Czynniki ryzyka jaskry

Zidentyfikowano wiele czynników ryzyka związanych z rozwojem jaskry. Ogólnie rzecz biorąc, ryzyko rozwoju jaskry jest bardzo małe w populacji ogólnej, ale istnieje kilka czynników ryzyka, które są związane z rozwojem PJOK21.

Główne czynniki ryzyka

Do głównych czynników ryzyka jaskry należą:

  • Zaawansowany wiek: Im jesteś starszy, tym bardziej prawdopodobne jest, że rozwiniesz jaskrę21. Ryzyko PJOK wzrasta z wiekiem25.
  • Rasa: Osoba czarnoskóra ma 4 razy większe ryzyko rozwoju jaskry niż osoba biała21. Afroamerykanie nie tylko częściej chorują na PJOK, ale także wcześniej rozwija się u nich jaskra w porównaniu do osób białych11.
  • Pozytywny wywiad rodzinny: Jeśli twój krewny pierwszego stopnia (rodzic lub rodzeństwo) ma jaskrę, twoja szansa na rozwój jaskry wzrasta 2-4 krotnie21. Badania bliźniąt potwierdzają genetyczny wpływ w PJZK, ale nie zidentyfikowano żadnego konkretnego genu26.
  • Podwyższone ciśnienie wewnątrzgałkowe (IOP): Jeśli twoje ciśnienie wewnątrzgałkowe przekracza 30 (mm Hg), szansa na rozwój jaskry jest 40 razy większa niż jeśli IOP jest poniżej 1521.
  • Płeć: Mężczyźni są bardziej podatni na PJOK niż kobiety (RR 1,28, p<0,01)25. Jednakże kobiety mają wyższe wskaźniki chorobowości niż mężczyźni zarówno dla jaskry (1,36% vs. 1,17%), jak i jaskry wpływającej na widzenie (0,48% vs. 0,41%)3.

W systematycznym przeglądzie i metaanalizie badań prospektywnych zidentyfikowano sześć czynników ryzyka PJOK, w tym leczenie ciśnienia wewnątrzgałkowego (meta-OR = 3,69; 95% CI = 2,64-5,15), pozytywny wywiad rodzinny jaskry (meta-OR = 2,49; 95% CI = 1,92-3,24), krótkowzroczność (meta-OR = 2,08; 95% CI = 1,59-2,70), podwyższone IOP (meta-OR = 1,13; 95% CI = 1,11-1,15), zaawansowany wiek (meta-OR = 1,07; 95% CI = 1,05-1,08) oraz płeć męska (kobiety: meta-OR = 0,76; 95% CI = 0,66-0,88)27.

Dodatkowe czynniki ryzyka

Inne udokumentowane czynniki ryzyka jaskry obejmują:

  • Choroby układowe: Takie jak cukrzyca, niedoczynność tarczycy i wysokie ciśnienie krwi28.
  • Pochodzenie etniczne: Osoby pochodzenia latynoskiego i niektóre populacje azjatyckie są również w bardzo wysokim ryzyku5.
  • Leczenie kortykosteroidami: Zwłaszcza krople do oczu, przez długi czas29.
  • Urazy oka: Lub pewne rodzaje operacji oka29.
  • Skrajna krótkowzroczność lub dalekowzroczność29.
  • Cienkie centrum rogówki29.

Ponadto jaskra może również rozwinąć się wtórnie do pewnych chorób układowych lub leczenia, takich jak cukrzyca, niedoczynność tarczycy i stosowanie kortykosteroidów28. Wszystkie wyżej wymienione czynniki ryzyka mogą indywidualnie lub zbiorowo wpływać na ryzyko jaskry28.

Tendencje epidemiologiczne i prognozy

Analizując trendy epidemiologiczne można zauważyć, że częstość występowania jaskry na świecie rośnie. W 2022 roku, częstość występowania jaskry wśród osób w wieku 18 lat lub starszych wynosiła 1,62% (95% UI, 1,33%-2,00%), a wśród osób w wieku 40 lat lub starszych 2,56% (95% UI, 2,10%-3,16%)30.

Częstość występowania jaskry wśród osób w wieku 18 lat lub starszych wahała się od 1,11% (95% UI, 0,89%-1,40%) w Utah do 1,95% (95% UI, 1,57%-2,39%) w Mississippi31. Czarnoskóre osoby dorosłe miały częstość występowania 3,15% (95% UI, 2,32%-4,09%) w porównaniu z 1,42% (95% UI, 1,10%-1,85%) wśród białych dorosłych31.

Przewiduje się, że do 2050 roku liczba osób z jaskrą w Stanach Zjednoczonych wzrośnie do 6,3 miliona z powodu starzenia się amerykańskiej populacji6. Co więcej, oczekuje się, że do 2050 roku 50% wszystkich pacjentów z jaskrą w Stanach Zjednoczonych będzie pochodzenia latynoskiego32.

Trendy regionalne i krajowe

W 2023 roku, szacunkowy odsetek zdiagnozowanych przypadków jaskry w 7MM wynosił około 42% całkowitej liczby przypadków, co wynika z takich czynników jak starzenie się populacji i ulepszone techniki diagnostyczne ułatwiające wczesne wykrywanie13. Około 7 milionów przypadków z całkowitej liczby zdiagnozowanych przypadków jaskry oszacowano w 7MM w 2023 roku i wskazano na wzrost w okresie badania13.

Kraj/Region Szacowana liczba przypadków jaskry (2023)
Stany Zjednoczone 2,5 miliona
UE4 i Wielka Brytania (łącznie) 3,0 miliony
Japonia 1,6 miliona

Źródło: Na podstawie danych z13

Wśród krajów UE4 i Wielkiej Brytanii, Niemcy miały najwyższą zdiagnozowaną populację chorych na jaskrę, z 0,7 miliona przypadków, następnie Francja i Włochy w 2023 roku13.

W Nigerii, badanie krajowe dotyczące ślepoty i upośledzenia wzroku wykazało, że całkowita częstość występowania jaskry wynosiła 5,02% (95% CI 4,60-5,47), co jest znacznie wyższe niż średnia światowa33. Wśród osób z pierwotną jaskrą, które miały przeprowadzoną gonioskopię (n=243), jaskra otwartego kąta była bardziej powszechna (86%) niż jaskra zamkniętego kąta (14%)33.

W Niemczech, na podstawie dużej administracyjnej bazy danych dotyczących roszczeń niemieckich, oszacowano jednoroczną częstość występowania PJOK na 1,70% i jednoroczną zapadalność na 0,17% w 2018 roku; oba wskaźniki wzrastały wraz z wiekiem, osiągając szczyt u osób w wieku 80-89 lat34.

Jaskra w populacjach specjalnych

Jaskra w populacji dziecięcej

Jaskra dziecięca stanowi grupę zaburzeń, które prowadzą do nadciśnienia wewnątrzgałkowego z następczym uszkodzeniem nerwu wzrokowego i utratą wzroku, jeśli nie są leczone. Odpowiada za 5% ślepoty w populacji pediatrycznej i dotyka ponad 300 000 dzieci na świecie35.

Częstość występowania pierwotnej jaskry wrodzonej (PCG) wynosi około 1 na 10 000-18 000 żywych urodzeń i zależy w dużym stopniu od pochodzenia etnicznego36. PCG jest wysoce rozpowszechniona w populacjach charakteryzujących się zawieraniem małżeństw w obrębie danej społeczności, a związek krwi jest silnie powiązany z chorobą36.

Ślepota spowodowana jaskrą u dzieci odpowiada za 18% dzieci w instytucjach dla niewidomych i 5% ślepoty pediatrycznej na świecie36. W krajach europejskich występuje przewaga mężczyzn w porównaniu do kobiet z PCG36.

Jaskra normalnego ciśnienia

Jaskra normalnego ciśnienia (NTG) jest powszechną formą pierwotnej jaskry otwartego kąta (PJOK), w której nie występuje zmierzone podwyższenie ciśnienia wewnątrzgałkowego (IOP)37.

Epidemiologia NTG stanowi intrygujące wyzwanie dla badaczy i klinicystów. Podczas gdy dokładna częstość występowania NTG może się różnić w zależności od regionu geograficznego, szacuje się, że stanowi ona znaczącą część wszystkich przypadków jaskry, a niektóre badania sugerują, że może stanowić nawet 30-40% wszystkich pacjentów z jaskrą37.

Badanie Collaborative Normal Tension Glaucoma Study (CNTGS) wykazało korzyści z obniżenia IOP w leczeniu pacjentów z NTG38. Badanie to wykazało, że 30-procentowa redukcja wyjściowego IOP skutkowała zmniejszonym ryzykiem progresji choroby38.

Nadzór i monitorowanie jaskry

System Nadzoru nad Wizją i Zdrowiem Oczu (VEHSS) oraz Szacunkowe Modele Jaskry VEHSS są podstawowymi szacunkami CDC dotyczącymi częstości występowania jaskry w Stanach Zjednoczonych3.

VEHSS dostarcza dane na temat procentu osób z jaskrą w Stanach Zjednoczonych według stanu, hrabstwa i różnych grup wiekowych, rasowych, etnicznych i płciowych3. Jest to główny środek CDC do pomiaru odsetka mieszkańców USA cierpiących na jaskrę, ich lokalizacji i tego, kim są3.

CDC wspiera projekty wykrywania jaskry w całym kraju poprzez swoją Inicjatywę Zdrowia Wizji (VHI) i Program Wykrywania Jaskry32. Badania te mają na celu dotarcie do populacji o wysokim ryzyku i przezwyciężenie wyzwań związanych z badaniami przesiewowymi i leczeniem32.

W amerykańskich siłach zbrojnych, analiza z wykorzystaniem Systemu Nadzoru Medycznego Obrony zidentyfikowała 37 718 nowych przypadków jaskry w okresie od 2013 do 2017 roku i ogólny wskaźnik zapadalności wynoszący 5,9 przypadków na 1 000 osobolat39. Większość przypadków (97,6%) została zdiagnozowana na wczesnym etapie jako jaskra graniczna; z tych przypadków granicznych, 2,2% postępowało do jaskry otwartego kąta w okresie badania39.

Wskaźniki jaskry były wyższe wśród nie-latynoskich czarnoskórych (11,0 na 1 000 osobolat), azjatyckich/wysp Pacyfiku (9,5) i latynoskich (6,9) członków służby, w porównaniu z nie-latynoskimi białymi (4,0) członkami służby40.

Wyzwania w monitorowaniu jaskry

Obecnie nie ma zadowalającego testu, który byłby odpowiedni do masowych badań przesiewowych w kierunku jaskry41. Strategie zapobiegania ślepocie z powodu jaskry będą musiały koncentrować się na identyfikacji czynników ryzyka i na tym, jak można je wykorzystać do określenia badań przesiewowych, leczenia i monitorowania10.

W niektórych krajach rozwijających się, nawet 90% przypadków jaskry pozostaje niewykrytych7. W większości przypadków ślepotę można zapobiec dzięki odpowiedniej kontroli i leczeniu7.

Wczesne wykrywanie i skuteczne zarządzanie jaskrą są kluczowe dla zachowania wzroku i zminimalizowania znaczących konsekwencji ekonomicznych17.

Implikacje dla zdrowia publicznego

Zaktualizowane szacunki częstości występowania jaskry mogą pomóc w opracowaniu, priorytetyzacji i ocenie strategii zdrowia publicznego w celu rozwiązania problemu jaskry, alokacji zasobów i dostosowania strategii zdrowia publicznego do grup najbardziej dotkniętych chorobą42.

Te nowe dane dotyczące częstości występowania jaskry mogą pomóc w planowaniu polityki związanej ze zdrowiem wzroku i będą cenne, ponieważ stany i lokalne społeczności pracują nad wsparciem swoich starzejących się populacji42.

Szacunki zostały opracowane przy użyciu danych z Systemu Nadzoru nad Wizją i Zdrowiem Oczu CDC (VEHSS)42. Szacunki te stanowią czwarty zestaw krajowych, stanowych i powiatowych szacunków stworzonych przez System Nadzoru nad Wizją i Zdrowiem Oczu, dołączając do wcześniej opublikowanych szacunków dotyczących upośledzenia widzenia i ślepoty, zwyrodnienia plamki żółtej związanego z wiekiem i retinopatii cukrzycowej42.

Wpływ jaskry na jakość życia

Jaskra ma znaczący wpływ na jakość życia i jest główną przyczyną ślepoty i utraty wzroku na świecie22. Jaskra spowodowana upośledzeniem widzenia poważnie wpływa na jakość życia i zdrową oczekiwaną długość życia pacjentów43.

Nakłada również duże obciążenie na rodziny i systemy opieki zdrowotnej43. Ze względu na podstępny początek i niski wskaźnik wykrywalności we wczesnych stadiach jaskry, większość pacjentów jest diagnozowana w zaawansowanych stadiach z rozległymi i nieodwracalnymi uszkodzeniami43.

Dlatego wczesne wykrywanie i interwencja są niezbędne do zapobiegania nieodwracalnym uszkodzeniom wzroku i związanej z tym niepełnosprawności43.

Strategie zdrowia publicznego

Tworzenie świadomości publicznej, nacisk na kompleksową ocenę, gdy pacjent odwiedza każdego okulistę w celu korekcji okularów lub z jakąkolwiek inną dolegliwością, pomogłoby we wcześniejszym wykrywaniu jaskry44.

Odpowiednia opieka lub terminowe skierowanie pomogłoby zaopiekować się potrzebującymi pacjentami i zapobiec ślepocie spowodowanej jaskrą44.

Wskazuje to na krytyczną potrzebę dokładnej kampanii badań przesiewowych w kierunku jaskry, aby chronić wzrok wielu osób, które albo nie są świadome swojego stanu jaskry, albo nie otrzymują opieki45.

  • #4 Epidemiology studies highlight glaucoma public health impact
    https://www.ophthalmologytimes.com/view/epidemiology-studies-highlight-glaucoma-public-health-impact
    Statistics released by the World Health Organization (WHO) in 2002 indicate glaucoma has become a more common cause of blindness than it was in the past, said Anne L. Coleman, MD, PhD, the Frances and Ray Stark Professor of Ophthalmology, Jules Stein Eye Institute, David Geffen School of Medicine at UCLA, Los Angeles. […] While glaucoma previously ranked third on the WHO list of leading causes of blindness worldwide, in the 2002 report the disease had moved up to second place. Overall, an estimated 12.3% of the worlds 37 million blind had lost their sight because of glaucoma. […] The bottom line is that glaucoma is a disease with a huge public health impact, and for that reason there is significant interest in directing human and financial resources toward its prevention and treatment, Dr. Coleman said.

    The worldwide prevalence of glaucoma is increasing. […] It is estimated that in 2010, 8.4 million individuals worldwide were blind from primary open-angle glaucoma. By the year 2040, it is estimated that there will be 22 million individuals worldwide who are blind from glaucoma. […] For some time we have known that individuals of African ancestry are at very high risk. We are now learning that Hispanic individuals and certain Asian populations also are at very high risk. […] Vision loss from glaucoma is silent, it is slow, it is progressive, it is irreversible, but it is treatable. Glaucoma blindness is preventable. […] The key to preserving vision is timely diagnosis and treatment, through regular complete eye examinations; and the purpose of glaucoma treatment is to allow the glaucoma patient to maintain his or her independence and quality of life.

    Glaucoma is one of the leading causes of irreversible blindness in the United States. More than 3 million Americans have glaucoma. By 2050, that number is expected to rise to 6.3 million due to the aging US population. Glaucoma costs the US economy $2.86 billion every year in direct costs and productivity losses. […] Currently, there is no cure for glaucoma. But if the disease is found early, it can be treated and managed before vision loss or blindness occurs. Because there are usually no symptoms, only 50% of people with glaucoma even know they have it. […] Certain population groups are at higher risk of becoming blind from glaucoma. These groups include Black or African American people, Hispanic or Latino people, people who are uninsured or underinsured, people living in poverty, and people living in rural areas with limited resources.
  • #7 Glaucoma Information Statistics – Glaucoma Information
    https://www.glaucomapatients.org/basic/statistics/
    Glaucoma is the most common cause of irreversible blindness. Based on prevalence studies, it is estimated that 79.6 million individuals will have glaucoma in 2020. This number is likely to increase to 111.8 million individuals in 2040. At least, half of those with glaucoma are unaware that they are affected. In some developing countries, 90% of glaucoma is undetected. It is estimated that more than 11 million individuals will be bilaterally blind due to glaucoma in 2020 (around 13% of the cases). In most cases, blindness can be prevented with appropriate control and treatment. Unfortunately, many individuals are unaware of the existence of glaucoma. A better awareness could prevent visual disability in many people. […] It is important for you to get yourself regularly screened for glaucoma. If you have been diagnosed to have glaucoma, effective treatment options are now available and regular treatment and follow up can help you to preserve your vision for your lifetime, avoiding unnecessary fear of going blind. You can live happily with glaucoma and enjoy an excellent quality of life, particularly if the disease is detected early and treated in time. Always remember that once you have glaucoma, you will have to be under the care of an eye doctor for the rest of your life. There is a lot of research going on and new treatments may become available for glaucoma in the near future.

    https://emedicine.medscape.com/article/1205421-overview
    Elevated IOP (ocular hypertension) is estimated to affect 5-10 million Americans, placing them at risk for developing glaucomatous damage. Each year, about 1% of individuals with ocular hypertension develop glaucomatous damage. Similarly, many patients with other risk factors, such as suspicious optic nerve appearance, nerve fiber layer defects, and family history of glaucoma without definite glaucomatous damage, are observed. […] More than 100 million people have elevated IOP. More than 3 million people worldwide are blind secondary to POAG; about 2.4 million people develop POAG each year. […] Glaucoma is the second most common cause of legal blindness (described as visual acuity [VA] of 20/200 or poorer and visual field of less than 20 in width of its diameter) in the United States, and it is the leading cause of blindness in African Americans. Between 80,000-116,000 persons are legally blind secondary to glaucoma. Each year, an additional 5,500 people are estimated to become legally blind. At least 2.25 million people older than 40 years have glaucoma, but only one half are aware of it and are being treated.

    Glaucoma represents a significant public health problem. Glaucoma affects more than 67 million people in the world, and approximately 10% of them are estimated to be blind from glaucoma. It is the leading cause of irreversible blindness in the world. In the United States, glaucoma affects more than 2.2 million people, and is the second leading cause of blindness in adults over the age of 40 (the first is macular degeneration). […] Epidemiology (study of disease in populations) of the open-angle glaucoma is sufficiently different from the angle closure glaucoma that each warrants a separate discussion. […] Prevalence of primary open angle glaucoma has been extensively studied by a number of well-designed clinical studies in different populations. In white populations, primary open angle glaucoma is present in 0.3 to 4.0% of the older population. In Asian populations, POAG is present in 0.5 to 2.6% of the older population. In the Hispanic population in the United States, POAG is present in 2.0%; however, the number of studies on Hispanic populations is limited. In black populations, the prevalence of POAG is higher and ranges from 2.9 to 8.8% of the older population. It is clear that the black population is at a higher risk of developing POAG than in other populations.
  • #10 Epidemiology studies highlight glaucoma public health impact

    Strategies to prevent blindness from glaucoma will need to focus on the identification of risk factors and how they can be used to determine screening, treatment, and monitoring. In that regard, ethnicity-related differences in glaucoma risk are important to consider. […] Glaucoma is three times more common in African-Americans than in whites and together with cataracts are a leading cause of blindness in African-Americans, while recent data from the Los Angeles Latino Eye Study indicate that glaucoma prevalence rises rapidly after age 65 in Hispanics and it is the most common cause of blindness in older Hispanics, Dr. Coleman said.

[…] Black individuals are also at greater risk of blindness from POAG, and this risk increases with age: in persons aged 46-65 years, the likelihood of blindness from POAG is 15 times higher among blacks than that among whites. […] The prevalence of primary angle-closure glaucoma (PACG) varies among different racial and ethnic groups. […] The prevalence is estimated at 0.1%, in Caucasian populations in the United States and Europe. […] The Inuit populations from the Arctic regions have the highest-known prevalence of PACG about 20 to 40 times higher than that for Caucasian. […] The available data suggests that for most Asian population groups, the prevalence of PACG is between that for Caucasian and Inuit populations.

  • #14 The Changing and Challenging Epidemiology of Glaucoma
    https://www.reviewofoptometry.com/article/the-changing-and-challenging-epidemiology-of-glaucoma
    The prevalence of glaucoma is believed to be about 2% (with estimates ranging between 1.6% and 2.7%) in adults over the age of 40. In the year 2000, an estimated 2.2 million Americans had glaucoma, including those either diagnosed or unknown. This number is expected to reach 3.3 million by the year 2020. The rapid growth in glaucoma is due to the aging of baby boomer population. […] Numerous studies have shown that the prevalence of glaucoma increases with age. The Eye Disease Prevalence Research Group developed estimates of glaucoma prevalence from data that included multiple US-based and international studies. The group estimated that open-angle glaucoma prevalence increased from 0.7% at age 40 to 7.7% for those over age 80. Self-reported epidemiologic data from the National Health Interview Survey found glaucoma prevalence increasing from 0.2% at age 18 to over 10.7% for those over 75. The growth in the oldest-old is important, as the prevalence of glaucoma triples in those over 75 compared to those aged 65.

    http://eyerounds.org/books/glaucoma_guide/chapter2.html
    In general, the risk of developing glaucoma is very small in general population. However, there are several risk factors that are associated with the development of POAG. As seen in Table 2-1, the black race is one such risk factor. Other risk factors include older age, positive family history of glaucoma, and elevated intraocular pressure. A black person has 4 times the risk of developing glaucoma than a white person. The older you are, the more likely you will develop glaucoma. If your first-degree relative (parent or sibling) has glaucoma, your chance of developing glaucoma increases by 2 to 4 fold. If your intraocular pressure is over 30 (mm Hg), the chance of developing glaucoma is 40 times greater than if the IOP is under 15. […] Epidemiology of PACG is less studied than that of open angle glaucoma. However, it is no less important. In fact, PACG may account for 64% of all glaucomas in Mongolia, and 50% of all glaucomas worldwide. […] Blindness can occur in angle closure glaucoma as well.

    Twin studies support a genetic influence in ACG, but no specific gene has been isolated. […] The definition of ACG by consensus now allows comparisons among studies, and the word glaucoma is used only when there is disc and field loss. […] The gonioscopic definition for angle closure is coverage of more than one-half of the pigmented meshwork without indentation. […] Recent quantitative measurements of the iris and angle with anterior segment optical coherence tomography that took the pupil’s size into account showed that the angle’s narrowing on dilation is partially due to changes in iris volume. […] Eyes with ACG lose less iris volume on dilation, making angle closure more likely. […] Choroidal expansion is five times more common in asymptomatic ACG eyes than in controls. A 20% choroidal expansion would dramatically increase IOP to 60 mm Hg yet would be invisible clinically. […] Research into the multiple dynamic features of ACG may explain its risk factors and lead to better diagnosis.

    Prevalence of glaucoma among people 18 years or older ranged from 1.11% (UI, 0.89%-1.40%) in Utah to 1.95% (UI, 1.57%-2.39%) in Mississippi. […] Black adults had a prevalence of 3.15% (UI, 2.32%-4.09%) compared with 1.42% (UI, 1.10%-1.85%) among White adults; adults in the Hispanic and all other racial and ethnic categories combined had a prevalence of 1.56% (UI, 1.13%-2.06%). […] This meta-analysis found that an estimated 2.56% of people 40 years or older have glaucoma, slightly more than estimated by previous studies. Black individuals are disproportionately affected. Prevalence estimates at the state and county level can help guide public health planning.

    Members of some racial and ethnic groups are at higher risk of developing glaucoma. For example: A 2016 study found that 81% of glaucoma cases among Hispanic or Latino people are undiagnosed and untreated compared to 73% in non-Hispanic White people. By the year 2050, it is expected that 50% of all glaucoma patients in the United States will be Hispanic people. Glaucoma is six times more common among Black or African American people than White people. […] CDC supports glaucoma detection projects across the country through its Vision Health Initiative (VHI) Glaucoma Detection Program. These studies are designed to reach populations at high risk and overcome challenges to screening and treatment. […] The goal of this study is to develop a program that can be expanded nationwide into both rural and urban communities to reach populations at high risk for glaucoma. […] The goal of this study is to evaluate the program to see if it can be effective in other communities. […] The goal of this study is to share program findings and create a model that other communities can use to provide similar services to prevent vision loss from glaucoma and other eye diseases.

    Glaucoma is the leading cause of irreversible blindness worldwide. […] Research findings of glaucoma in Nigeria will significantly increase our understanding of glaucoma in Nigeria, in people of the West African diaspora and similar population groups. […] We determined the prevalence and types of glaucoma in Nigeria from the Nigeria National Blindness and Visual Impairment cross-sectional Survey of adults aged 40 years. […] A total of 13,591 participants in 305 clusters were examined (response rate 90.4 %). […] There were 682 participants with glaucoma; a prevalence of 5.02 % (95 % CI 4.605.47). […] Among those with definite primary glaucoma that had gonioscopy (n=243), open-angle glaucoma was more common (86 %) than angle-closure glaucoma (14 %). […] Nigeria has a high prevalence of glaucoma which is largely open-angle glaucoma.

    Pediatric glaucoma is a group of disorders that result in ocular hypertension with subsequent optic nerve damage and vision loss if left untreated. It accounts for 5% of blindness in the pediatric population and affects more than 300,000 children in the world. […] Several studies have used the CGRN classification for the categorization of childhood glaucoma. Bouhenni et al. conducted a study in Akron, Ohio. The study included 104 patients diagnosed with childhood glaucoma or glaucoma suspects from 2008 through 2018. Males represented 64% of the whole cohort. The authors found that glaucoma suspect was the most prevalent category in their study (46%). […] Another study conducted by Mokbel et al. in Mansoura Ophthalmic Center in Dakahelia, Egypt. They included 207 glaucoma patients (305 eyes) who have been seen at their institute over the period of 4 years. They reported that males represented 63.8% and that PCG was the predominant glaucoma category (55.1%).

    Normal tension glaucoma (NTG) is a common form of primary open angle glaucoma (POAG) in which there is no measured elevation of the intraocular pressure (IOP). […] The epidemiology of NTG presents an intriguing challenge for researchers and clinicians. While the exact prevalence of NTG can vary by geographic region, it is estimated to comprise a significant proportion of all glaucoma cases, with some studies suggesting it may account for up to 30-40% of all glaucoma patients. […] Current research tackles the disparity demonstrated by the aforementioned data, suggesting that other factors/predispositions within specific ethnic groups may be playing a significant role in the pathogenesis of NTG. […] A recent cross-sectional study aimed to further describe a potential link between the incidence of NTG in patients with dementia.

    A recent study demonstrated that persons with NTG had increased risk for developing vascular dementia (VaD), with particular increased risk when diagnosed with glaucoma at ages 70. […] The Collaborative Normal Tension Glaucoma Study (CNTGS) demonstrated the benefit of IOP reduction for the treatment of patients with NTG. […] The study concluded that a 30 percent reduction in baseline IOP resulted in a reduced risk of disease progression. […] The CNTGS trial was therefore instrumental in demonstrating the role of IOP in the pathogenesis of NTG and the benefit of treatment to lower it.

    Update: Incidence of Glaucoma Diagnoses, Active Component, U.S. Armed Forces, 20132017 […] Glaucoma is an eye disease that involves progressive optic nerve damage and vision loss, leading to blindness if undetected or untreated. This report describes an analysis using the Defense Medical Surveillance System to identify all active component service members with an incident diagnosis of glaucoma during the period between 2013 and 2017. The analysis identified 37,718 incident cases of glaucoma and an overall incidence rate of 5.9 cases per 1,000 person-years (p-yrs). The majority of cases (97.6%) were diagnosed at an early stage as borderline glaucoma; of these borderline cases, 2.2% progressed to open-angle glaucoma during the study period. No incident cases of absolute glaucoma, or total blindness, were identified. Rates of glaucoma were higher among non-Hispanic black (11.0 per 1,000 p-yrs), Asian/Pacific Islander (9.5), and Hispanic (6.9) service members, compared with non-Hispanic white (4.0) service members. Rates among female service members (6.6 per 1,000 p-yrs) were higher than those among male service members (5.8). Between 2013 and 2017, incidence rates of glaucoma diagnoses increased by 75.4% among all service members.

    The vast majority of glaucoma diagnoses in active component service members (97.6%) represent early stage disease (borderline or suspect glaucoma). Over the surveillance period, incidence rates of glaucoma diagnoses increased by 75.4% overall; the greatest increase occurred in service members 20 years of age, which may reflect improved detection among younger service members. […] There is no cure for glaucoma, and vision loss caused by glaucoma does not return with treatment; treatment only stops or reduces the rate of new vision loss. Glaucoma prevention efforts should continue to focus on early detection through periodic and comprehensive eye examinations performed by an eye care professional (optometrist or ophthalmologist). […] During the 5-year surveillance period, a total of 37,718 incident cases of glaucoma were identified. This represents an overall incidence rate of 5.9 per 1,000 person-years (p-yrs). The rate of incident glaucoma diagnoses among female service members (6.6 per 1,000 p-yrs) was 14% higher than that of male service members (5.8 per 1,000 p-yrs). The rate was highest among non-Hispanic black service members (11.0 per 1,000 p-yrs) and it was more than double the rate among non-Hispanic white service members (4.0 per 1,000 p-yrs). Rates among both Asian/Pacific Islander (9.5 per 1,000 p-yrs) and Hispanic (6.9 per 1,000 p-yrs) service members were also elevated in comparison with non-Hispanic white service members.

    There are approximately 250,000 sufferers from Primary Open Angle Glaucoma (POAG) in the UK, with possibly a similar number remaining undiagnosed in the community. POAG patients now represent 25-30% of the outpatient load of ophthalmology departments in the UK, and this outpatient burden will increase as life expectancy increases and as our methods of detection of glaucoma become more sensitive. […] A general finding from population-based surveys is that approximately 50% of people found to have glaucoma were previously undiagnosed, hence the role of general practitioners, optometrists and technicians as primary screeners has been investigated. […] Consensus is yet to be reached on the most effective way to screen for glaucoma, and at present there is no satisfactory test that would be suitable for mass screening for glaucoma.

    Significant disparities existed in incidence rates for glaucoma across geographic regions and age groups. Further research is needed to understand which risk factors drive glaucoma incidence in different socioeconomic strata for tailored health policy on preventing glaucoma. […] Glaucoma, characterised by progressive optic neuropathy, is a leading cause of irreversible visual impairment and blindness worldwide. In 2020, an estimated 76 million individuals globally were affected by glaucoma, with approximately 4.5 million experiencing moderate to severe visual impairment and 3.2 million suffering from blindness. With the anticipated rise in the aging population, the number of prevalent glaucoma cases is projected to reach 112 million by 2040. Glaucoma-induced visual impairment seriously affects the life quality and healthy life expectancy of patients. It also imposes a large burden on families and health care systems. Due to the insidious onset and low detection rate in the early stages of glaucoma, most patients are diagnosed in advanced stages with extensive and irreversible damage. Therefore, early detection and intervention are essential to prevent irreversible visual damage and associated disability.

    Also due to the large geographical and ethnic diversity, the pattern of glaucoma varies in different regions of India. […] This tertiary institutional-based, cross-sectional study reflects the pattern of glaucoma and its subtypes in Southern India. […] Among primary glaucoma, POAG and PACG had similar disease severity; however, JOAG had greater severity at presentation. […] Patients with secondary glaucoma were noted to be younger and presented with higher IOP with severe disc damage and with severe field defects. […] Creating public awareness, emphasis on comprehensive evaluation when patient visits any ophthalmologist for a spectacle correction or any other complaint would help with earlier detection of glaucoma. […] Appropriate care or timely referral would help care for the deserving patients and prevent blindness due to glaucoma.

    The prevalence of glaucoma at the tertiary eye center during the ten-years was 660 out of 19000 representing 3.5% of the total cases reported to the eye care facility. […] This ten-year clinic-based prevalence study indicated that fewer persons with glaucoma are receiving care relative to the reported prevalence in the population of Ghana. […] This points to the critical need for a thorough glaucoma screening campaign to protect the eyesight of the many Ghanaians who are either unaware of their glaucoma status or not receiving care. […] The majority of the patients despite having essentially normal visual acuity were found to have lost significant peripheral vision as per the visual field assessment. […] The inherent threat is that given the most accessible and utilized means of transport in Ghana is by road, most of these patients who own cars per their socioeconomic status or engaged in commercial driving do not only endanger their own lives but that of other road users and passengers.
