温州市152名幼儿屈光状态调查分析

A research of children' s refraction in Wen-zhou city

目的:调查和了解幼儿屈光状态,加强幼儿视力保健。方法:采用随机整群抽样方法,对152名(299眼)3岁至6岁的幼儿用0.50％托吡卡胺滴眼液麻痹睫状肌后检影验光,采用SPSS 11.0进行统计学分析。结果:屈光状态:全体儿童不同年龄组间两两比较,方差分析提示对于球镜和等效球镜,4岁组和3、5、6岁组之间差异有显著性(P<0.05),其余各组之间差异无显著性。对于柱镜,3岁组和4岁组女性差异有显著性,其余各组之间差异无显著性。4岁时各类屈光不正患病率最高。儿童屈光状态中,散光以低度顺规散光为主;总体以单纯远视最多见,复合远视散光次之。结论:幼儿中各类屈光不正患病率很高,应该引起必要的关注。提倡早期检查和早期治疗。

Objective: To study the children ' s refraction, improve the quality of pediatric visual care.Methods: 152 children(299 eyes,3 - 6 years old) were selected randomly. The refraction status was determined with retboscopy after cycloplegia by tropicamide. Results: The status of refraction: between the children in different ages, comparing sphere and equivalent sphere, the analysis of one-way ANOVA shows that the differences are significant between 4-age group and other groups; comparing cylinder, there is significant between 3-age and 4-age female group, others are of little significant difference. Conclusion: Astigmatism degrees of the children(3 - 6 years old) differ little in ages. It shows that the low degree with-the-rule astigmatism is the main cause, of which simple hyperopia is the first reason, the compound hyperopic astigmatism is the second reason. The prevalence rate of all kinds of ametropia is high, and deserve much attention.
