Leniwe oko (ambliopia)
Epidemiologia

Ambliopia, będąca główną przyczyną utraty widzenia jednoocznego u dzieci i młodych dorosłych, ma globalną częstość występowania około 1,36% (95% CI: 1,27-1,46%), z wyższą częstością u chłopców (1,40%, 95% CI: 1,10-1,70%) niż u dziewcząt (1,24%, 95% CI: 0,94-1,54%). Występowanie różni się geograficznie: Europa 2,90%, Ameryka Północna 2,41%, Azja 1,09%, Afryka 0,72%. Najczęściej ambliopia rozwija się do 7 roku życia, a czynniki ryzyka obejmują wcześniactwo, niską masę urodzeniową, rodzinne występowanie, opóźnienia rozwojowe oraz różnice refrakcyjne powyżej 1D, które zwiększają ryzyko nawet 40-krotnie. Dominujące etiologie to anizometropia (~50%), zez (~19%) oraz ich kombinacja (~27%). Wczesna diagnostyka i leczenie przed 7 rokiem życia są kluczowe dla osiągnięcia ostrości wzroku 20/20, natomiast nawroty występują u około 25% dzieci w ciągu roku od zakończenia terapii.

Epidemiologia leniwego oka (ambliopia)

Leniwe oko (ambliopia) stanowi istotny problem zdrowia publicznego i jest główną przyczyną utraty widzenia jednoocznego u dzieci i młodych dorosłych. Dane epidemiologiczne dotyczące występowania amblyopii na świecie różnią się znacznie w zależności od regionów i okresów badań, jednakże aktualne dane wskazują na ogólnoświatowe rozpowszechnienie tego schorzenia.12

Częstotliwość występowania na świecie

Według najnowszych metaanaliz ogólnoświatowa częstość występowania amblyopii wynosi około 1,36% (95% CI: 1,27-1,46%).1 Inne źródła podają nieco szerszy zakres od 1,1% do 1,8%.2 Częstość występowania amblyopii jest wyższa u chłopców (1,40%, 95% CI: 1,10-1,70%) niż u dziewcząt (1,24%, 95% CI: 0,94-1,54%), co potwierdza iloraz szans OR = 0,885 (95% CI: 0,795-0,985, P = 0,025).3

Kompleksowa metaanaliza globalna obejmująca ponad 1,8 miliona pacjentów z 60 badań wykazała łączny wskaźnik występowania na poziomie 1,44%, z zakresem od 1,17% do 1,78%.4 Szacuje się, że w 2019 roku około 99,2 miliona ludzi na całym świecie było dotkniętych amblyopią, a przewiduje się wzrost do 175 milionów do 2030 roku i 220 milionów do 2040 roku.5

Różnice regionalne

Występowanie amblyopii wykazuje znaczne zróżnicowanie geograficzne. Wskaźniki występowania w różnych częściach świata kształtują się następująco:6

  • Europa: 2,90%7
  • Ameryka Północna: 2,41%8
  • Azja: 1,09%9
  • Afryka: 0,72%10

W Stanach Zjednoczonych częstość występowania amblyopii szacuje się na poziomie 1-4%.11 W Wielkiej Brytanii występuje u około 2-5% populacji, a aż 90% wizyt zdrowotnych związanych ze wzrokiem u dzieci dotyczy właśnie amblyopii.12

Występowanie w grupach wiekowych

Amblyopia najczęściej rozwija się od urodzenia do siódmego roku życia, kiedy to system wzrokowy jest w trakcie formowania.13 Badania populacyjne wykazały zróżnicowane wskaźniki występowania, z szacunkami od 0,7% do 2,6% wśród dzieci w wieku od 30 do 70 miesięcy oraz od 1,0% do 5,5% u starszych dzieci.14

Według Cleveland Clinic, amblyopia dotyka około 5% dzieci poniżej 15 roku życia i jest najczęstszą przyczyną utraty widzenia w tej grupie wiekowej.15 Inne źródła podają, że amblyopia występuje u około 2-3% populacji, co oznacza, że dotyka około 1 na 50 dzieci w USA.16 Statystyki wskazują, że około 2,5 miliona dzieci poniżej 10 roku życia cierpi na to schorzenie, a każdego roku diagnozuje się dodatkowo 250 000 nowych przypadków.17

Trendy czasowe

Interesujący jest fakt, że częstość występowania amblyopii zmniejsza się w niektórych regionach. Badanie przeprowadzone w Izraelu na 1,5 miliona nastolatków wykazało spadek częstości występowania amblyopii z 1,59% w 1993 roku do 0,87% w 2017 roku, co oznacza dwukrotny spadek w ciągu tego okresu.1819

Czynniki ryzyka i predyktory

Zidentyfikowano kilka czynników zwiększających ryzyko wystąpienia amblyopii:20

  • Wcześniactwo i niska masa urodzeniowa2122
  • Rodzinne występowanie amblyopii2324
  • Opóźnienia rozwojowe25
  • Niższy status społeczno-ekonomiczny2627
  • Niższe wyniki w testach funkcji poznawczych28

Ryzyko rozwoju amblyopii znacząco wzrasta przy określonych czynnikach. Gdy różnica w błędzie refrakcji między oczami mieści się w zakresie 1D do 2D równoważnika sferycznego, prawdopodobieństwo rozwoju amblyopii jest 4,5 razy wyższe. To ryzyko może wzrosnąć nawet 40-krotnie, gdy różnica w błędzie refrakcji przekracza 2D.29

Typy amblyopii i ich rozpowszechnienie

Amblyopia najczęściej występuje jako schorzenie jednostronne, choć zdarzają się przypadki obustronnej amblyopii, gdy oba oczy doświadczają zaburzeń widzenia we wczesnym rozwoju.30 Najczęstsze przyczyny amblyopii i ich względna częstość występowania to:31

Badania z Wielkiej Brytanii potwierdzają podobny rozkład przyczyn: około jednej trzeciej przypadków wynika z zeza, jednej trzeciej z anizometropii, a pozostała jedna trzecia z kombinacji obu tych czynników.37

Nawroty i skuteczność leczenia

Istotnym aspektem epidemiologicznym jest częstość nawrotów amblyopii po zakończonym leczeniu. Badania wykazują, że amblyopia nawraca u około 25% dzieci w ciągu roku od zakończenia leczenia.3839 Ryzyko nawrotu jest wyższe w przypadku lepszej ostrości wzroku w momencie zakończenia leczenia, większej liczby linii poprawy podczas poprzedniego leczenia oraz wcześniejszej historii nawrotów.40

Skuteczność leczenia jest ściśle związana z wiekiem rozpoznania i rozpoczęcia interwencji. Wczesne wykrycie i agresywne leczenie przed ukończeniem 7 roku życia daje najlepsze rezultaty, z dużą szansą na osiągnięcie ostrości wzroku 20/20 w słabszym oku.41 Leczenie jest znacznie mniej skuteczne po 9 roku życia, choć nowsze badania wskazują, że także starsze dzieci i nawet dorośli mogą osiągnąć pewną poprawę dzięki nowoczesnym metodom terapeutycznym.4243

Nadzór epidemiologiczny nad amblyopią

Znaczenie wczesnej diagnostyki

Wczesna diagnostyka amblyopii jest kluczowa dla skutecznego leczenia i zapobiegania trwałej utracie wzroku. Amerykańska Grupa Zadaniowa ds. Profilaktyki (USPSTF) zaleca badania przesiewowe wzroku u wszystkich dzieci przynajmniej raz między 3 a 5 rokiem życia w celu wykrycia amblyopii lub czynników ryzyka jej wystąpienia.44

Dzieci z podwyższonym ryzykiem amblyopii powinny być kierowane na badanie okulistyczne jak najszybciej po zidentyfikowaniu czynnika ryzyka.45 Amerykańska Akademia Okulistyki, Amerykańskie Stowarzyszenie Okulistyki Dziecięcej i Zeza oraz Amerykańska Akademia Pediatrii wspierają badania przesiewowe wzroku przed rozpoczęciem nauki w przedszkolu.46

Programy badań przesiewowych

Programy badań przesiewowych mają kluczowe znaczenie dla wczesnego wykrywania amblyopii. Kraje, które wprowadziły wczesne programy badań przesiewowych wzroku, odnotowały zmniejszenie częstości występowania amblyopii.47 Istnieje wiele technik wykrywania amblyopii, wszystkie o różnym stopniu swoistości, czułości, złożoności i kosztów.48

Skuteczność intensywnych protokołów badań przesiewowych w wykrywaniu amblyopii w młodym wieku przekłada się na lepszą ostrość wzroku w chorym oku w wieku 7,5 lat.49 Wyniki badań sugerują, że badania przesiewowe powinny rozpoczynać się już w wieku 6 miesięcy i być kontynuowane przez cały okres wczesnego dzieciństwa.50

Wpływ społeczno-ekonomiczny

Amblyopia stanowi istotny problem społeczno-ekonomiczny. Badania wykazały, że jest główną przyczyną utraty widzenia jednoocznego u dorosłych.51 Osoby z amblyopią mają wyższe ryzyko całkowitej ślepoty z powodu potencjalnej utraty widzenia w zdrowym oku z innych przyczyn.52

Co więcej, badania wykazały, że dzieci z amblyopią czytają znacznie wolniej niż ich rówieśnicy, nawet gdy ostrość wzroku w chorym oku jest zmniejszona tylko do poziomu 20/30.53 Amblyopia może również wpływać na wyniki związane z motoryką precyzyjną w zadaniach akademickich, takich jak czas wypełniania testów wielokrotnego wyboru.54

Niedawne badanie wykazało, że dorośli, którzy mieli amblyopię w dzieciństwie, mają zwiększone ryzyko wystąpienia chorób metabolicznych i sercowo-naczyniowych:5556

Wyzwania w nadzorze epidemiologicznym

Pomimo znaczenia wczesnego wykrywania, amblyopia często pozostaje niezdiagnozowana u małych dzieci, ponieważ rodzice mogą nie zdawać sobie sprawy, że ich dziecko zmaga się z zaburzeniami widzenia.64 Dziecko z amblyopią może mieć normalne widzenie w jednym oku, co prowadzi do polegania na tym oku, podczas gdy drugie słabnie z czasem.65

Niestety, pediatrzy i badania przesiewowe w szkołach często nie mają zasobów i szkoleń niezbędnych do skutecznego wykrywania amblyopii.66 Większość badań przesiewowych jest zaprojektowana do wykrywania oczywistych problemów i może pomijać bardziej subtelne aspekty ostrości wzroku, co skutkuje brakiem diagnozy w wielu przypadkach.67

Często niedocenianym aspektem amblyopii jest fakt, że wiele dzieci z tym schorzeniem nie wykazuje żadnych widocznych objawów, więc mogą pozostać niezdiagnozowane do znacznie późniejszego wieku.68 Podkreśla to krytyczne znaczenie kompleksowych badań wzroku, ponieważ standardowe badania przesiewowe w szkołach, a nawet podstawowa ocena wzroku przez pediatrów, często nie wykrywają tego schorzenia.69

Nowe kierunki w monitorowaniu i leczeniu

Metody leczenia amblyopii u dzieci ewoluowały, oferując szerszy zakres rozwiązań w zależności od nasilenia stanu i preferencji pacjenta oraz jego rodziców.70 W badaniu 419 dzieci poniżej 7 roku życia z amblyopią, terapia atropiną przyniosła porównywalne wyniki do zakrywania oka (patching).71

Najnowsze badania sugerują, że starsze dzieci, a nawet dorośli z długotrwałą amblyopią, mogą odnieść korzyści z leczenia za pomocą programów komputerowych lub aplikacji, które stymulują zmiany neuronalne prowadzące do poprawy ostrości wzroku i czułości na kontrast.72 W badaniu klinicznym 44 dzieci i dorosłych z amblyopią (w wieku od 9 do 54 lat), 70,5% uczestników osiągnęło poprawę ostrości wzroku o co najmniej dwie linie na standardowej tablicy okulistycznej po pełnym cyklu sesji treningowych RevitalVision.73

Obiecujące wyniki przynosi również wykorzystanie technologii rzeczywistości wirtualnej. Urządzenia VR wykorzystujące technologię dichoptyczną/dwuoczną, gdzie każde oko ogląda oddzielny i niezależny ekran, a różne bodźce są prezentowane każdemu oku jednocześnie, wykazują szybszą poprawę ostrości wzroku niż tradycyjne metody.74 Badania wykazały, że niektóre z zaawansowanych urządzeń cyfrowych mogą poprawić ostrość wzroku szybciej niż zakrywanie oka – pacjenci wykazują znaczną poprawę ostrości po jednym do dwóch miesięcy, w porównaniu z czterema do sześciu miesięcy wymaganymi do osiągnięcia podobnej poprawy poprzez typowe zakrywanie oka.75

Zalecenia dla zdrowia publicznego

Na podstawie danych epidemiologicznych można sformułować następujące zalecenia dla zdrowia publicznego:7677

  • Wdrożenie powszechnych badań przesiewowych wzroku dla dzieci przed rozpoczęciem edukacji przedszkolnej78
  • Zwiększenie alokacji środków na badania przesiewowe wzroku i monitorowanie przestrzegania leczenia wśród populacji podatnych na rozwój amblyopii7980
  • Edukacja rodziców i opiekunów na temat znaczenia wczesnych badań wzroku81
  • Dalsze badania mające na celu lepsze zrozumienie barier tworzących różnice w występowaniu amblyopii wśród różnych sektorów społeczeństwa82
  • Promowanie zdrowego stylu życia od dzieciństwa, szczególnie wśród dzieci z amblyopią, ze względu na potencjalne powiązania z ryzykiem chorób metabolicznych i sercowo-naczyniowych w dorosłości83

Ciągły nadzór nad amblyopią powinien pozostać integralną częścią opieki pediatrycznej. Pacjenci i ich rodzice powinni być edukowani o potrzebie kontynuowania kontroli, możliwości nawrotu, ryzyku trwałej utraty wzroku oraz możliwości rozwoju amblyopii związanej z zakrywaniem oka w dobrym oku z powodu nadmiernego terapeutycznego zakrywania.84

    Amblyopia, a decrease in visual acuity, is a major public health problem with a prevalence of 1 to 4 percent in the United States. […] Amblyopia is a major public health problem with an estimated prevalence of 1 to 4 percent in the United States. It is the most common cause of monocular vision loss in children and young adults. Early recognition and prompt referral are crucial, especially during infancy and childhood, to prevent permanent loss of vision. […] Studies have shown that early screening for amblyopia results in better outcomes. Countries that have instituted early vision screening programs have reduced rates of amblyopia. […] Ongoing surveillance for amblyopia should remain an integral part of well-child care. Patients and their parents should be educated about the need for continued follow-up, the possibility of recurrence, the risk of permanent vision loss, and the possibility of developing occlusion-related amblyopia in the good eye from excessive therapeutic patching.

    Amblyopia is common, with estimated prevalence of 2-5% in the UK. It is the most frequently treated disorder in paediatric ophthalmology. […] One Chinese study found that prevalence rates in adults mirrored those of children. This is thought to be due to failure of early detection or of treatment efforts in childhood. […] About a third of cases are due to strabismus, a third due to anisometropia and a further third due to a combination of the two. Other causes are relatively rare.

    https://www.mayoclinic.org/diseases-conditions/lazy-eye/symptoms-causes/syc-20352391
    Lazy eye (amblyopia) is reduced vision in one eye caused by abnormal visual development early in life. Amblyopia generally develops from birth up to age 7 years.

    Functional visual impairments in children are primarily caused by amblyopia or strabismus. This study aimed to determine the prevalence and clinical profile of amblyopia and strabismus among individuals aged 316 years in Shanghai, China. A total of 920 children were enrolled in our study. Among them, 223 (24.24%) children were identified as amblyopia. 30 (3.26%) children were diagnosed with strabismus. The proportion of patients with amblyopia and strabismus was determined as 24.24% and 3.26% in our study. Amblyopia is defined as reduced visual acuity (VA) accompanied by many factors, such as anisometropia, strabismus, and vision deprivation. The estimated incidence of amblyopia is 13.5% worldwide. The reported rates of amblyopia ranged widely from 0.93 to 10.12% of children suffering from VI. The anisometropic type was the most common for unilateral amblyopia, accounting for the entire cohort, occupying 68.99% of the total cohort. In our study, 30 (3.26%) children were identified as having strabismus. This rate is similar to that reported in population-based studies conducted in China. A relatively high prevalence of amblyopia (24.24%) was identified in the present population, compared with the common school-based assessment. Early screening for amblyopia and strabismus is imperative to ensure timely intervention. […] These findings shed light on further longitudinal studies targeting the age-related changes in amblyopia, strabismus and refraction errors. Therefore, efforts should be made to manage uncorrected refractive errors, amblyopia, and strabismus among children in Shanghai.

    Amblyopia is the leading cause of monocular vision loss in children. Early recognition and treatment are important to prevent vision loss. The U.S. Preventive Services Task Force recommends vision screening for all children at least once between three and five years of age to detect the presence of amblyopia or its risk factors. Amblyopia is the leading cause of childhood monocular vision loss, with an estimated prevalence of 1% to 6%, and it is responsible for permanent vision loss in 2.9% of adults. Amblyopia recurs in 25% of children, so continued surveillance is important. Early diagnosis of amblyopia is key to optimize the likelihood of successful treatment. Recommendations from the U.S. Preventive Services Task Force (USPSTF), supported by the American Academy of Family Physicians, suggest screening all children three to five years of age for amblyopia or its risk factors at least once. Children with an increased risk of amblyopia should be referred for an ophthalmologic examination as soon as a risk factor is identified. Careful surveillance is necessary for children successfully treated for amblyopia because 25% will have recurrence within one year. […] Treatment regimens should be individualized based on age, visual acuity, previous treatments, adherence, and psychosocial factors.

[…] Amblyopia generally starts at birth or during early childhood before age 7. […] It’s important to correct amblyopia as early as possible, before the brain ignores vision in the affected eye. […] Amblyopia will not go away on its own, and untreated amblyopia can lead to permanent visual problems and poor depth perception. If amblyopia is detected and aggressively treated before the age 7, in many cases the weak eye will be able to develop 20/20 vision.

Only children can develop amblyopia, and without treatment, it can cause a lifetime of uncorrectable visual loss. […] In most cases, amblyopia affects only one eye. One exception is bilateral refractive amblyopia. In this condition, an uncorrectable vision loss in both eyes results from severe farsightedness, nearsightedness, or astigmatism in both eyes, which is not corrected early. […] Early treatment for amblyopia is always best. […] Patching is generally not as effective after age 9. Patching of older individuals is seldom worthwhile. Some cases of amblyopia can be resistant to therapy. The decision to stop treatment can be difficult but is sometimes best for both the child and the family.

    Amblyopia is the leading cause of monocular vision loss in children. Early recognition and treatment are important to prevent vision loss. The U.S. Preventive Services Task Force recommends vision screening for all children at least once between three and five years of age to detect the presence of amblyopia or its risk factors. Amblyopia is the leading cause of childhood monocular vision loss, with an estimated prevalence of 1% to 6%, and it is responsible for permanent vision loss in 2.9% of adults. Amblyopia recurs in 25% of children, so continued surveillance is important. Early diagnosis of amblyopia is key to optimize the likelihood of successful treatment. Recommendations from the U.S. Preventive Services Task Force (USPSTF), supported by the American Academy of Family Physicians, suggest screening all children three to five years of age for amblyopia or its risk factors at least once. Children with an increased risk of amblyopia should be referred for an ophthalmologic examination as soon as a risk factor is identified. Careful surveillance is necessary for children successfully treated for amblyopia because 25% will have recurrence within one year. […] Treatment regimens should be individualized based on age, visual acuity, previous treatments, adherence, and psychosocial factors.

    Amblyopia is a relatively common disorder and a major cause of visual impairment in children. It represents an insult to the visual system during the critical period of development whereby an ocular pathology (ex. strabismus, anisometropia, high refractive error, or deprivation) interferes with normal cortical visual development. Approximately 3-5% of children are affected by amblyopia.[2] […] The key to prevention is detection. There are numerous techniques to detect amblyopia, all with varying degrees of specificity, sensitivity, complexity, and cost. These include a complete ophthalmic examination, photoscreening, visual evoked potentials, acuity charts, and tests of stereopsis and binocular function. Children who are at higher risk for amblyopia should be watched closely for early signs of this condition. In general, the quicker amblyopia is detected and addressed, the less negative effect it has on the visual system. Vision screening is advocated on the state level to screen as many children as possible for this disease prior to the age of kindergarten. Early intervention results in better overall vision. This is why the American Association for Pediatric Ophthalmology and Strabismus, the American Academy of Pediatrics, and the American Academy of Ophthalmology all support pre-kindergarten vision screening for children.

Early recognition and prompt referral are crucial, especially during infancy and childhood, to prevent permanent loss of vision. […] Studies have shown that early screening for amblyopia results in better outcomes. Countries that have instituted early vision screening programs have reduced rates of amblyopia. […] Ongoing surveillance for amblyopia should remain an integral part of well-child care. Patients and their parents should be educated about the need for continued follow-up, the possibility of recurrence, the risk of permanent vision loss, and the possibility of developing occlusion-related amblyopia in the good eye from excessive therapeutic patching.

    Amblyopia, also known as lazy eye, is the loss or lack of development of clear vision in one or both eyes. […] Amblyopia or lazy eye is often associated with crossed eyes or is a large difference in the degree of nearsightedness or farsightedness between the two eyes. […] It usually develops before age 6 and does not affect side vision. […] Early diagnosis increases the chance of a complete recovery. […] The American Optometric Association recommends that children have a comprehensive optometric examination by 6 months of age and again at age 3. […] Lazy eye will not go away on its own. […] If left undiagnosed until the preteen, teen or adult years, treatment takes longer and is often less effective. […] Treatment for lazy eye may include a combination of prescription lenses, prisms, vision therapy and eye patching. […] A comprehensive eye exam by the age of 6 months and again by 3 years of age.

    Poltavski and Biberdorf say its important to begin treating amblyopia early because the success rate with current treatment standards drops significantly after age 8 a statistic largely attributed to a coinciding decrease in patch compliance rates as children get older. […] The virtual reality headsets incorporate dichoptic/binocular technology, whereby the child watches shows or plays interactive video games as each eye views a separate and independent screen. Different stimuli are presented to each eye simultaneously. […] Evidence has shown that some of the high-tech digital devices may improve visual acuity more quickly than patching with patients showing significantly improved acuity after one to two months compared with the four to six months required to achieve similar improvement through typical patching.

  • #76 Frontiers | The Global Prevalence of Amblyopia in Children: A Systematic Review and Meta-Analysis
    https://www.frontiersin.org/journals/pediatrics/articles/10.3389/fped.2022.819998/full
    Epidemiological data about the prevalence of amblyopia around the world vary widely among regions and periods. This meta-analysis aimed to determine the global prevalence of amblyopia in children. A total of 97 studies were included, including 4,645,274 children and 7,706 patients with amblyopia. The overall worldwide pooled prevalence of amblyopia was 1.36% (95%CI: 1.27–1.46%). The prevalence of amblyopia was higher in males (1.40%, 95%CI: 1.10–1.70%) than in females (1.24%, 95%CI: 0.94–1.54%) (OR = 0.885, 95%CI: 0.795–0.985, P = 0.025). The results of the meta-regression analysis showed that there were no significant associations between the prevalence of amblyopia and geographical area, publication year, age, sample size, and whether it was carried out in a developed or developing country (all P > 0.05). […] In conclusion, amblyopia is a significant vision problem worldwide, and public health strategies of early screening, treatment, and management are important.

    Amblyopia is a relatively common disorder and a major cause of visual impairment in children. It represents an insult to the visual system during the critical period of development whereby an ocular pathology (ex. strabismus, anisometropia, high refractive error, or deprivation) interferes with normal cortical visual development. Approximately 3-5% of children are affected by amblyopia.[2] […] The key to prevention is detection. There are numerous techniques to detect amblyopia, all with varying degrees of specificity, sensitivity, complexity, and cost. These include a complete ophthalmic examination, photoscreening, visual evoked potentials, acuity charts, and tests of stereopsis and binocular function. Children who are at higher risk for amblyopia should be watched closely for early signs of this condition. In general, the quicker amblyopia is detected and addressed, the less negative effect it has on the visual system. Vision screening is advocated on the state level to screen as many children as possible for this disease prior to the age of kindergarten. Early intervention results in better overall vision. This is why the American Association for Pediatric Ophthalmology and Strabismus, the American Academy of Pediatrics, and the American Academy of Ophthalmology all support pre-kindergarten vision screening for children.

[…] Amblyopia is a major public health problem with an estimated prevalence of 1 to 4 percent in the United States. It is the most common cause of monocular vision loss in children and young adults. Early recognition and prompt referral are crucial, especially during infancy and childhood, to prevent permanent loss of vision. […] Studies have shown that early screening for amblyopia results in better outcomes. Countries that have instituted early vision screening programs have reduced rates of amblyopia. […] Ongoing surveillance for amblyopia should remain an integral part of well-child care. Patients and their parents should be educated about the need for continued follow-up, the possibility of recurrence, the risk of permanent vision loss, and the possibility of developing occlusion-related amblyopia in the good eye from excessive therapeutic patching.

    Dr Siegfried Wagner from UCL Institute of Ophthalmology and Moorfields Eye Hospital said: “Vision and the eyes are sentinels for overall health – whether heart disease or metabolic dysfunction, they are intimately linked with other organ systems. […] It is rare to have a ‘marker’ in childhood that is associated with increased risk of serious disease in adult life, and also one that is measured and known for every child – because of population screening. […] The large numbers of affected children and their families may want to think of our findings as an extra incentive for trying to achieve healthy lifestyles from childhood.
