A population based survey of rural communities in the Akinlalu-Ashipa ward of Ife North Local Government in Osun State, Nigeria, was conducted to determine the prevalence and causes of blindness. 2921 inhabitants were screened by a random cluster sample technique, out of whom 27 were blind in both eyes. The overall prevalence rate of blindness (best corrected visual acuity less than 3/60 in the better eye) was found to be 0.9% (95% confidence interval 0.84-0.96%). The rate of blindness increased with age, especially from age 60. The major causes of blindness were cataract and its sequelae (48.1%), onchocerciasis (14.8%), primary open angle type glaucoma (11.1%), corneal scar/phthisis bulbi (7.4%) and optic atrophy (7.4%). About half of the blindness is potentially curable through cataract surgery, and a third preventable through health education, early diagnosis and prompt treatment.
在尼日利亚奥孙州伊费北地方政府阿金拉卢-阿希帕区对农村社区进行了一项基于人群的调查，以确定失明的患病率和病因。采用随机整群抽样技术对2921名居民进行了筛查，其中27人双眼失明。失明的总体患病率（较好眼最佳矫正视力低于3/60）为0.9%（95%置信区间0.84 - 0.96%）。失明率随年龄增长而增加，尤其是60岁以后。失明的主要原因是白内障及其后遗症（48.1%）、盘尾丝虫病（14.8%）、原发性开角型青光眼（11.1%）、角膜瘢痕/眼球痨（7.4%）和视神经萎缩（7.4%）。约一半的失明可通过白内障手术治愈，三分之一可通过健康教育、早期诊断和及时治疗预防。
