- W3136111019 abstract "To determine the prevalence of refractive errors and causes of visual impairment in school children in Enugu State, South-eastern Nigeria.A descriptive cross-sectional, school-based survey in children aged 5-15 years from selected primary and junior secondary schools (public and private) in both urban and rural communities of Enugu State was carried out. Ocular examinations were performed on them according to the Refractive Error in School-age Children (RESC) protocol.A total of 1167 children were examined. The mean age (standard deviation) was 10.58 ± 3.0 years. Females were 653 (54.4%) of the study population. The uncorrected, presenting and best-corrected visual acuity of ≤20/40 (6/12) in the better eye of the children in this study were 3.6%. 3.5% and 0.4%. Among the children that had visual impairment, refractive error accounted for 33.3% of reduced vision while the overall prevalence of refractive error was 2.1%. Prevalence of myopia was 1.9% and hyperopia, 0.1%. The most prevalent astigmatism was ≤0.75 dioptre cylinder.The prevalence of refractive error in this study is low, with myopia being more common. Despite the low prevalence of refractive error, school vision screening is still important for African children as it serves as an opportunity to identify other ocular morbidities among the children." @default.
