1000例儿童屈光状态分析

Analysis of Refraction Status of 1 000 Children

目的了解学龄前及学龄儿童的屈光状态.方法对昆明医科大学第一附属医院2009年1月到2012年12月眼科门诊接待的3-12岁1 000例儿童（2 000只眼）进行睫状肌麻痹下视网膜检影验光,并对其屈光状态情况进行统计学分析.结果近视最多,占658只眼（65.8%）,远视296只眼（29.6%）混合散光46只眼（4.6%）;其中学龄前近视眼29只（2.9%）,学龄后近视眼629只（62.9%）;学龄前远视眼128只（12.8%）,学龄后远视眼168只（16.8%）;学龄前混合散光眼25只（2.5%）,学龄后混合散光眼21只（2.1%）.结论 3~6岁儿童屈光不正以远视为主,6-12岁儿童屈光不正以近视为主,随年龄增长近视人数增多及程度加深,弱视多发于远视眼.

Objective To investigate the refractive state of preschool and school-age children. Methods In the First Affiliated Hospital of Kunming Medical University fromJanuary 2009 to December 2012,1000 cases of 3 ~12 years old children（2000 eyes） admitted in the Ophthalmic Outpatient Clinic were enrolled in this study, and they were given retinal screening shadow optometry under cycloplegia, the refractive state was statistically analyzed.Results There were 658 eyes（65.8%） of myopia,296 eyes（29.6%） of hyperopia,and 46 eyes（4.6%） of mixed astigmatism. There were 29 eyes（2.9%） of pre-school myopia,and 629 eyes of post-school myopia（62.9%）;128（12.8%） eyes of pre-school hyperopia and 168（16.8%） eyes of post-school hyperopia; 25（2.5%） eyes of pre-school mixed astigmatism and 21（2.1%） eyes of post-school mixed astigmatism. Conclusion Hyperopia is the major refractive error in children aged 3 ~ 6 years old, while myopia is the major refractive error in children aged 6 ~ 12 years old. With the growing age, the incidence and degree of myopia is increasing,amblyopia is more frequent than hyperopia.
