“…For presenting VI, the prevalence was 10.8%, similar to what was found in Nepal [21] and Malaysia [23], which was 9.1% and 10.1%, respectively. However, in Brazil [24] and Vietnam [20], the prevalence was slightly higher (with 14.5% and 12.2%, respectively), and in Ghana [22] it was much lower (3.7%). The prevalence of presenting VI is an indicator that so much reflects the coverage of the health system and accessibility to eye health services, which may vary depending on each country and region, and may also be determined by economic and socio-cultural factors that lead people to live with VI.…”

Visual impairment (VI) can significantly interfere in the child’s daily activities and quality of life, having a negative effect on their development and learning. The aim of the study was to determine the prevalence of VI and associated demographic factors in students examined during the program “Moçambique te vejo melhor”. This study was cross-sectional and retrospective, based on the 2018/19 edition of the program. Eye examinations were performed in secondary school students, aged between 12 and 20 years, of five districts in Nampula province. The examination included visual acuity, non-cycloplegic refraction and assessment of the anterior and posterior segment and ocular adnexa. The prevalence of uncorrected, presenting and best-corrected VI found was 18.3%, 10.8%, and 5.0%, respectively. Refractive error (RE) had a prevalence of 24.7%, and the age groups between 15–17 years and 18–20 years were significantly associated with myopia (with OR: 4.9 and OR: 8.8, respectively), as well as the 11th and 12th grade (OR: 8.1 and OR: 10.7, respectively), and Malema district had association with myopia (ORa: 0.4) and hyperopia (ORa: 0.4 and OR: 0.3) as a protective factor. The prevalence of RE and VI was relatively high, showing the need for greater intervention at the school level.

“…Similarly to our results, a recent study on school-age Brazilian children (age range: 7-17) found a frequency of visual impairment and blindness of 14.58% considering PVA (no BCVA measurements were performed). 25 On the other hand, a previous population-based study (age range: 11-14) performed in Brazil found a prevalence of presenting and best-corrected visual acuity <20/32 in the better vision eye of 2.67%, and 0.41%, respectively. 21 When considering only those in the same age range (i.e.…”

Objective: The purpose of this study was to investigate frequency and causes of visual impairment in school-aged children from low-income areas of Sao Paulo evaluated by the “Ver na Escola” project, an initiative from São Paulo city government in partnership with a local non-governmental organization, launched aiming to offer free-of-charge visual screening and treatment to children enrolled in public schools. Methods: Vision screening included presenting VA, ocular motility, and automated dynamic refraction assessment. Children referred for the ophthalmologist were submitted to automated and subjective static refraction, best-corrected VA, slit lamp, and fundus examination. Results: A total of 17972 children were included in the study. Our findings show a frequency of visual impairment and blindness of 14.6% considering presenting VA decreasing to 1.3% after appropriate refractive correction. The main causes of visual impairment and blindness were uncorrected refractive errors (96.77%), amblyopia (0.88%), and retinal abnormalities (0.37%). Conclusion: The frequency of visual impairment and blindness in the population under study was 14.6% mainly due to uncorrected refractive errors. These results support the need for expanded and perennial refractive services through school-based programs associated with provision of spectacles. These initiatives should be sustainable and pursued by health and school authorities to provision of screening and eye care for those in need.

“…O presente estudo evidenciou uma prevalência de baixa AV de 66,87% (n=111) nos escolares, superando a estimativa de 20% das crianças em idade escolar prevista no Caderno temático do PSE (3) . Esse dado contrapõe-se também às frequências apresentadas em outros estados brasileiros, como Amazonas (6) , com 6,3%; em Minas Gerais 34,8% no ano de 2010 (10) e recentemente, em 2018, 14,5% (11) ; no estado de Santa Catarina (12) , 9,4%; no Rio Grande do Sul (13) prevalência de 10,88%; e no estado São Paulo (14) , 13,1%.…”

“…Um estudo realizado em Santa Catarina (11) revelou que 47,3% das crianças apresentaram baixa AV compatível com a autopercepção negativa da qualidade da visão, o que se aproxima dos 61% (n=101) evidenciados neste estudo. Outros estudos observaram que muitos escolares apresentam dificuldade em expressar sua percepção visual dada as frequências relativamente elevadas de crianças que referiram autopercepção visual normal entre aqueles que tinham baixa AV e vice-versa (9,20) .…”

Objetivo: verificar a prevalência de baixa acuidade visual em escolares do Distrito Federal.Método: estudo quantitativo, transversal, realizado com 166 crianças e seus respectivos responsáveis, matriculadas em uma escola da rede pública de educação do Distrito Federal. Aplicou-se a Escala Optométrica de Snellen e questionários. Os dados foram submetidos à análise estatística de cunho descritivo e inferencial.Resultados: 111 (66,87%) escolares apresentaram baixa acuidade visual, sendo que 126 (75,9%) crianças nunca receberam nenhum atendimento relacionado à saúde ocular. Dos 13 escolares que faziam uso de lentes corretivas, 11 (84,6%) apresentaram acuidade visual menor que 0,8 mesmo com a correção.Conclusão: a elevada prevalência de baixa acuidade visual identificada revela fragilidades nas ações de prevenção de problemas visuais dos estudantes e demanda planejamento de ações contínuas e efetivas em prol da prevenção da cegueira e da promoção da saúde ocular na infância.
