昆明市学龄前儿童散光特征及分析

目的探讨学龄前视力低常儿童散光眼的主要类型、程度、轴向的分布规律及与弱视的关系．方法对昆明市妇幼保健院2010年1月至2011年11月门诊接待的学龄前儿童进行散瞳验光，并对其中477例831只眼的散光情况进行统计学分析．结果复性远视散光最多，占65.8％，其他依次为混合散光13．8％，单纯远视散光9．0％，复性近视散光8．7％，单纯近视散光23％．学龄前儿童散光度多分布在0．50D-2．00D之间，占42．0％．散光轴向：顺散光占95．9％，逆规散光占2．4％和斜轴散光1．7％．结论复性远视散光是学龄前儿童散光的主要类型，散光与弱视的形成密切相关．

The Characteristic Analysis of Astigmatism in Preschool Children in Kunming

Objective To explore the types, degree and distribution regularities of axial direction in astigmatism preschool children and the relationship of astigmatism and amblyopia. Methods Mydriasis optometry was performed for preschool children in our hospital outpatient reception from 2010 to 2011, and the astigmatism in 831 eyes of 477 cases were statistically analyzed. Results The compound hyperopic astigmatism was the most, accounting fbr 65.8%, followed by mixed astigmatism （13.8%）, simple hyperopia astigmatism （9%）, compound myopia astigmatism （8.7%） and simple myopia astigmatism （2.3%）. Preschool children astigmatism degree distribution was distributed among 0.50 D and 2.00 D, accounting for 42%. For astigmatism axial, the astigmatism with rule, astigmatism against the rule and oblique astigmatism was accounted for 95.9%, 2.4% and 1.7%, respectively. Conclusion Compound hyperopic astigmatism is a main type of astigmatism in preschool children, and astigmatism is closely related to the formation of amblyopia.
