摘要
目的了解南宁市学龄前儿童眼散光的主要类型及分布规律,为儿童散光防治提供参考。方法采用整群随机抽样法,随机选取南宁市3～6岁学龄前儿童2 304名(4 608眼),采用标准对数视力表检测视力,Suresight自动验光仪测定散光状况。结果受检的4 608眼中,散光眼≥0.75 DC和≥1.25 DC的检出率分别为40.4%和12.3%,散光检出率随年龄增长而下降(χ2=18.659,P<0.01)。散光度分布以低度散光(0.75～1.00 D)、远视散光和顺规散光为主。不同年龄的散光度、散光类型和散光轴向分布差异均无统计学意义(P值均>0.05)。结论南宁市3～6岁学龄前儿童中散光患病率与国内其他地区一致,矫正高度散光、逆规和斜轴散光是学龄前儿童眼病防治的重点。
Objective To investigate the main type and distribution of astigmatism among the preschool children in Nanning,and to provide evidence for the prevention and treatment.Methods Totally 4 608 eyes of 2 304 preschool children aged 3-6 years old were selected,the astigmatism were determined by SureSight handheld autorefractor and the vision acuity were tested using standard logarithmic visual acuity chart.Results Of the 4 608 eyes,the detective rate of astigmatism（≥0.75 DC） and astigmatism（≥1.25 DC） was 40.4% and 12.3%,respectively.The detective rate of astigmatism reduced with age increasing（χ2=18.659,P0.01）.In the astigmatic eye（≥0.75 DC）,astigmatism 0.75-1.00 DC,compound hyperopic astigmatism and astigmatism with the rule were the mainly type.The distribution of astigmatism magnitude in different age had no statistical difference（P0.05）,as well as the distribution of astigmatism type and astigmatism axis in difference age had no statistical difference（P0.05）.Conclusion The prevalence of astigmatism in Nanning preschool children is similar to other city of China.It was the key for preventing amblyopia and strabismus to correct the high astigmatism,astigmatism against the rule and oblique astigmatism timely.
