“…In contrast to the above-mentioned African studies, in Brazil, Couto et al 25 reported the main causes of blindness to be retinopathy of prematurity (21%), optic nerve atrophy (18%) and congenital glaucoma (16%). A review study of blindness and low vision in America and the Caribbean found the major causes of low vision to be cataract, retinopathy of prematurity, optic atrophy and glaucoma.…”

Background: Low vision and blindness have significant implications, resulting in a generally reduced quality of life amongst the sufferers. Aim:To determine the prevalence and causes of low vision and blindness amongst learners at the Akropong School for the Blind. Setting:The study was conducted in Akropong School for the Blind, Ghana. Methods:A cross-sectional study design was used. Eye examinations included measurements of presenting distance visual acuity (PDVA) with the Tumbling 'E' distance LogMAR chart. Anterior and posterior segments were examined with an ophthalmoscope and a slit lamp.Results: Two hundred and sixty-eight (N = 268) learners comprising 157 (58.6%) males and 111 (41.4%) females took part in this study and their ages ranged from 4 to 43 years (mean and standard deviation [SD] = 15.79 ± 6.15 years). The results indicated that 76.1% were classified as blind and 23.9% of the learners had low vision. The leading cause of low vision was glaucoma (39.1%) followed by pseudophakia (21.9%) and retinopathy (18.8%). The most common causes of low vision and blindness based on pathology found on ocular anatomical structures were corneal opacity/phthisis bulbi (35.5%), followed by glaucoma (25%), cataract (13.4%) and retinopathy (10.8%). Conclusion:The leading causes of low vision and blindness identified in this study were because of avoidable diseases such as corneal opacity/phthisis bulbi and glaucoma. This highlighted the need for adequate primary eye care services, equitable eye health workforce distribution and eye health awareness in Ghana to help prevent low vision and blindness.

“…Blindness is understood as visual acuity worse than 20/400 and low vision as visual acuity worse than 20/60 in the better eye (3) . The impact of this deficiency is exemplified with: functional impairment, limitation and restriction of participating and performing daily activities, as well as impairment of independence and autonomy of respondents (4) , and lack of financial resources, physical safety and protection, of transport and dependence on medication or treatments, among others (5) .…”

Objective: to investigate the master students' expressions about feelings, difficulties and challenges arising from participation in sociodrama "as if" they were blind. Methods: qualitative study. Participants were eight Master students in nursing. They used sociodrama, a video recorder and the Content Analysis technique. In implementing the sociodrama, the steps were followed were warm-up, drama, comments and theoretical processing. Results: the following thematic categories emerged: the role as blind person triggering limitation, blocking and fear; the role as blind person triggering a confused notion of one's own body; spontaneity and creativity expressed by Master students. Conclusion: the Master students expressed the feeling of fear to walking in an environment with which they were already familiar, had difficulty in eating because of the confused notion of their own body, and could reflect on the challenge of caring for the blind person, because they realized that they were professionally unprepared to take care of these individuals.Objetivo: investigar as autoexpressões de mestrandas acerca dos sentimentos, dificuldades e desafios decorrentes da participação em sociodrama "como se" fossem cegas. Métodos: estudo qualitativo. Participaram oito mestrandas em enfermagem. Utilizaram-se sociodrama, uma filmadora e Análise de Conteúdo. Na execução do sociodrama, foram seguidas as etapas de aquecimento, dramatização, comentários e processamento teórico. Resultados: emergiram as categorias temáticas: O papel de cega desencadeando limitação, bloqueio e medo; O papel de cega desencadeando uma noção confusa do próprio corpo; A espontaneidade-criatividade manifestada pelas mestrandas. Conclusão: as mestrandas expressaram o sentimento de medo ao se mobilizarem em ambiente com o qual já estavam familiarizadas, tiveram dificuldade para se alimentar devido à noção confusa do próprio corpo, e puderam refletir acerca do desafio que é cuidar da pessoa cega, pois perceberam que, profissionalmente, estavam despreparadas para cuidar destes indivíduos.
