目的了解北京市海淀区儿童的屈光状况,为防治屈光不正提供依据。方法应用Suresight手持自动验光仪对17356名4月～6岁儿童(34712只眼)进行屈光检查。结果儿童群体屈光筛查异常率为21.22%。随年龄增长,屈光异常率逐渐下降,3岁时明显下降,4～5岁时又有上升趋势。屈光不正中散光占多数,为19.16%,但随年龄增长呈下降趋势。从各年龄组球镜、柱镜均数可看出随着儿童年龄增长其屈光值逐渐减低。统计得到了各年龄组球柱镜的参考值范围。结论了解儿童各年龄屈光状况非常必要,可以发现潜在问题,预测发展趋势,为早期干预提供依据。
Objective To understand the refractive status of children in Haidian District, Beijing, to provide basis for prevention and treatment of refractive errors. Methods 17356 children (34712 eyes) aged from 4 months to 6 years were examined with Suresight handheld automatic refractometer. Results The abnormal rate of refraction of children was 21.22%. With age, the rate of refractive error gradually decreased, significantly decreased at the age of 3, 4 to 5 years old, there is an upward trend. Astigmatism accounted for the majority of astigmatism, 19.16%, but with the decline of age showed a downward trend. From the age of all spherical, cylinder average can be seen as children age their refraction decreased. Statistics obtained by the age group lenticular reference range. Conclusion It is necessary to understand the refractive status of children at all ages, to identify potential problems, predict the development trend and provide the basis for early intervention.
