Background: The present study is first of its kind to evaluate causes of visual impairment of blind students in Nepal and assess their need for low vision rehabilitation services. Aim: To evaluate causes of vision impairment of students enrolled in blind schools in Nepal and assess the need for low vision rehabilitation services in these students. Materials and methods: A survey was conducted in 12 blind schools in Nepal, which were registered with Nepal Association for Welfare of Blindness (NAWB).It was conducted by a team of an ophthalmologist and an optometrist, by using standard eye examination protocols of the World Health Organization Prevention of Blindness Program (WHO/ PBL). Results: Of the 345 students enrolled in 12 schools, 285 students were examined (response rate of 82.61%). The students were in the 5 - 29 years age group. Nearly three-fourth of the children had become blind within one year of age and 52.3% visually impaired at birth and 20.7% developed vision impairment within one year of age. After refraction, 26 students (9.12%) had mild visual impairment, 21 students (7.37%) had severe visual impairment and 238 students (83.51%) were blind. The main cause of vision impairment was found to be corneal 35.79% and retina diseases, mainly dystrophy, 20.35% followed by problems with the whole globe, lens and optic nerve, accounting for 13.33%, 12.63% and 12.98% respectively. The major etiological factors were those of childhood such as Vitamin A deficiency, measles and similar causes (42.11%) followed by hereditary causes (25.26%). Of the total students examined, 48.07% were visually impaired due to preventable causes and 16.14% treatable aggregating to 64.21% of avoidable blindness. Fifty seven (28.22%) students could read smaller than 2 M print size after low vision assessment for near and 33(15.78%) students benefited with telescopic trial for distance low vision. Conclusion: In Nepal, renewed focus on providing best possible quality of life for visually impaired children by proper low vision assessment and eye health education focusing on, general public and community health workers, with governmental and institutional support is required to achieve Vision 2020 objectives to decrease childhood blindness.

Vision Care

Most causes of childhood blindness in Ghana are avoidable. Over 40 % of the students in the school for the blind in Ghana have functional residual vision that requires low-vision care. Corneal blindness is the commonest form, followed by cataract. Retinal blindness is rare and is usually from hereditary or congenital causes. The Expanded Program of Immunization (EPI) in the Ghana health service has been very successful, with measles coverage for under one-year-olds of 95 %. This should now translate into a decline in measles-related corneal blindness, a common preventable occurrence. This then brings challenges in cataract management into focus. Provision of sustainable intervention services for low-vision care in children is a priority for the Prevention of Childhood Blindness program in Ghana. Barriers to access range from parents’ negative perceptions, societal/cultural misconceptions, and inadequate resources, to absence of collaboration and coordination between low-vision care providers and weak national support. Clients usually come from families within the lower socioeconomic groups and often find the low-vision devices unaffordable. A successful program for intervention is more likely to succeed when it is subsidized, at least until a reasonable impact has been made. One must, however, strike a good balance between cost recovery, which is more likely to ensure sustainability of the program, and subsidization.

Tajam penglihatan adalah daya lihat yang mampu dilakukan seseorang. Tajam penglihatan normal adalah apabila seseorang dapat melihat huruf, angka, maupun bentuk dalam berbagai macam ukuran pada kartu Snellen dengan jarak 20 kaki (20/20). Katarak merupakan salah satu penyebab terjadinya gangguan penglihatan terbanyak kedua setelah gangguan refraksi yang tidak terkoreksi. Penelitian ini bertujuan untuk mengetahui faktor-faktor yang mempengaruhi timbulnya low vision setelah operasi bedah katarak di Rumah Sakit Muhammadiyah Palembang. Penelitian ini menggunakan desain penelitian deskriptif kuantitatif dengan pendekatan cross sectional menggunakan data rekam medis pasien yang sudah menjalani operasi katarak di Rumah Sakit Muhammadiyah Palembang periode Januari 2017-April 2018. Besar sampel penelitian ini adalah 31 orang. Hasil penelitian ini menunjukkan bahwa pada kontrol keempat pasca operasi, ada 38,7% subjek yang tetap memiliki low vision. Subjek penelitian sebagian besar terdiri dari individu lansia akhir (74,2%), terdapat 2 orang subjek yang mengalami komplikasi intra operasi (6,4%), dan terdapat 9 orang subjek yang mengalami komplikasi pasca operasi (29,1%). Timbulnya lowvision setelah operasi katarak tidak dipengaruhi oleh usia (p = 1,000) dan komplikasi intraoperasi (p = 1,000), namun dipengaruhi oleh adanya komplikasi pasca operasi (p = 0,043). Faktor risiko timbulnya lowvision pasca operasi katarak adalah adanya komplikasi pasca operasi. Oleh karena itu, perlu upaya pencegahan dari berbagai sisi agar tidak terjadi komplikasi pasca operasi katarak.
