PURPOSE
The aim of the study was to determine the prevalence of myopia at the community level.
METHODS
A population-based, cross-sectional study was planned in 40 clusters among children identified with subnormal vision in the urban community of Delhi. House-to-house visits were conducted for visual acuity screening of 20,000 children aged 0-15 years using age appropriate visual acuity charts. All the children with visual acuity of < 6/12 in any eye in the age group between 3 and 15 years and inability to follow light in age group 0-3 years were referred for detailed ophthalmic examination.
RESULTS
A total of 13,572 (64.7%) children belonged to the age group of 6-15 years. Of these, a total of 507 (3.7%) were found to be having myopia (spherical equivalent of -0.50 DS or worse in one or both eyes) with positive association with higher age groups.
CONCLUSION
The estimated prevalence of myopia is 3.7%; the proportion of uncorrected myopia was 45%, which reflects that refractive error services need to be improved further.
目的
本研究旨在确定社区层面近视的流行率。
方法
计划在德里城市社区中 40 个聚类中开展一项基于人群的横断面研究，对视力低于正常的儿童进行识别。对 20000 名 0-15 岁的儿童进行视力筛查，使用适合年龄的视力表进行视力检查。所有年龄在 3-15 岁之间、任何一只眼视力低于 6/12，以及年龄在 0-3 岁之间无法追随光线的儿童，都需要进行详细的眼科检查。
结果
共有 13572 名（64.7%）儿童属于 6-15 岁年龄组。其中，共有 507 名（3.7%）患有近视（一只或两只眼睛的等效球镜度数为-0.50 DS 或更差），且与较高年龄组呈正相关。
结论
估计近视的患病率为 3.7%；未矫正近视的比例为 45%，这表明需要进一步改善屈光不正服务。
