目的 对平凉市崆峒区幼儿园在园儿童视力进行筛查,了解各年龄组儿童视力状况,分析视力异常儿童屈光状态,为进一步做好儿童眼保健工作提供依据.方法 整群抽取6所幼儿园在园儿童1 920名,应用图形视力表筛查儿童视力.结果 1 920名儿童中视力异常者有189人,异常率为9.84%.随着年龄的增长,视力异常率增高,5岁儿童最高,6岁时视力异常率下降.各年龄组间视力异常率比较有显著性差异(χ2=8.642,P<0.05).各年龄组儿童平均正常视力随年龄增长而逐渐提高,视力异常儿童的屈光状态以远视为主,占55.56%.结论 每年至少应进行1次儿童视力筛查,可有效预防其眼病的发生,使儿童的视觉异常在敏感期或最佳期得到纠正.加强儿童眼保健健康教育宣传,从而引起社会各届的高度重视,共同做好儿童眼保健工作.%Objective To screen the vision of kindergarten children in Pingliang Kongdong District, understand children' s visual acuity of each age group and analyze refractive status of the children with vision disorders, so as to provide evidence for further improving children' s eye health care.

It was highest in 5-year-old children, but it declined in 6-year-old children. The differences in abnormal vision rate among different age groups were statistically significant (X2 = 8. 642,P <0.05 ). Average normal vision was improved with the increasing of age in each group, and refractive status of children with abnormal vision was mainly hyperopia, occupying 55. 56%.
