学龄前儿童散光特征分析

目的 探讨学龄前儿童散光的类型、程度及轴向分布情况.方法 对3～8岁儿童1980例(2288只眼)行1%阿托品常规散瞳检查,结果进行统计分析.结果 散光类型分布:复性远视散光最多占62.15%、混合性散光18.05%、复性近视散光9.31%.散光程度分布:0.50～2.0DC占75.88%、2.25～3.0DC占15.73%、3.25～4.0DC占6.78%、大于4.25DC占8.39%;散光轴向分布:顺规散光占96.24%、逆规散光占2.84%、斜轴散光占0.92%.所有患儿中弱视患者占58.83%.结论 复性远视散光是学龄前儿童散光的主要类型,以顺规散光为主.散光与弱视密切相关.

The characters of astigmatic eyes in the preschool children

Objective To investigate distribution rules in preschool children, the main type ,degree and axis of astigmatism. Methods 1980 cases (2288 eyes )of astigmatism whose age were 3-8 years old were given 1% atropine sulfate gutta and statistically analyzed.Results In astigmatic eyes, compound hyperopin astigmatism was the most counting for 62.15%, mixed astigmatism 18.05%, compound myopia astigmatism 9.31%o In the constituent ratio of astigmatic diopter, 0.50DC-1.00DC was 75.83%, 2.25DC-2.00DC 15.73%, 2.25DC-3.00DC 15.73%, 2.25DC-4.0DC 6.78%,>4.25DC 8.39%. Direct astigmatism is mainly distribution of astigmatism (96.24%). The ratio of amblyopia was 58.83%. Conclusion The main type of astigmatism at preschool age is compound hyperopia astigmatism. There is an association betweenastigmatism and amblyopia.
