2023例弱视儿童散光状况调查

Prevalence of astigmatism in 2023 children with amblyopia

摘要:

目的：调查弱视儿童中散光的主要类型、分布规律。方法：选取4~11岁弱视儿童2023例(3657眼)，对其散光的分布情况进行调查。结果：3657只眼中，散光眼(≥0.50 D)占91.9%，散光眼构成比随年龄增长而下降。散光分布类型中，复合远视所占比例最高(38.8%)，且随着年龄的增加，其所占比例呈增长趋势。轴向分布中以顺规散光的构成比最高，占90.1%；不同年龄散光轴向分布差异有统计学意义(P<0.01)。不同弱视程度儿童的散光度、散光类型和散光轴向分布差异有统计学意义(P<0.05)。结论：4~11岁弱视儿童中散光眼比例高，所占比例随年龄增长而降低；年龄和弱视程度可能是弱视儿童散光分布的影响因素。

Abstract:

OBJECTIVE: To investigate the prevalence, type and distribution of astigmatism in children with amblyopia. METHODS: A total of 2023 children with amblyopia (aged 4-11 years, 3657 eyes) were recruited. The prevalence of astigmatism was investigated. RESULTS: Of the 3657 amblyopic eyes, 91.9% presented astigmatism (≥0.5 D). The proportion of eyes with astigmatism decreased with the increasing age. Compound hyperopic astigmatism was the most common type of astigmatism (38.8%) and its prevalence increased with the increasing age in children with amblyopia. Astigmatism with the rule was the most common (90.1%) in the axial distribution test. There were statistical significances in the axial distribution of astigmatism in different age groups. Statistical significances were also found in the degree, type and axis of astigmatism among the children with mild, moderate and severe amblyopia (P<0.05). CONCLUSIONS: The prevalence of astigmatism in children with amblyopia is high but is reduced with age. The age and the degree of amblyopia might be influential factors in the distribution of astigmatism.
