儿童屈光不正与弱视关系探讨

目的 探讨儿童屈光不正与弱视的关系。方法 对520例患儿（928眼）进行散瞳验光。其中男279例，女241例，年龄3～13岁，记录并统计弱视的发病情况。结果 患儿远视、近视及混合性散光分别占46．77％、45．15％及8．08％；远视及混合性散光的弱视患病率高于近视性，差别高度显著性（P〈0．01）；学龄前患儿以远视为主，学龄期患儿以近视为主；学龄前患儿弱视患病率高于学龄期；弱视患病率随屈光不正程度的增加而升高，差异显著（P〈0．01）。结论 妨碍儿童视觉功能的屈光不正以远视、近视为主，混合性散光最少；弱视防治重在学龄前，近视防治重在学龄期。

Correlative Study between Children Crook of Refraction and Amblyopia

Objective To investigate children error of refraction with amblyopia.Methods Carry on the scattered pupil and have an eye test to 520 infants(928 eyes),279 boys,241 girls,3~13 years old.Results Long sight,near-sighted and mixing astigmatism account for 46.77%.45.1 5% and 8.08% respectively.The rate of amblyopia of long sight and mixing astigmatism is higher than near-sighted( P <0.01).The preschool children mainly show long sight,and near sighted mainly occur in school children. The rate of preschool children amblyopia is higher than that of school children.The rate of amblyopia increases with the increasing extent of error of refraction( P <0.01). Conclusion What hinder children's sight most are long sight and near sighted.Mixing astigmatism stands for the least percentage.Amblyobia should be prevented during preschool age,while near sighted during school age mainly.
