【摘要】 目的:分析3～12岁视力不良儿童210只散光眼的散光度及散光轴向分布情况。方法:对3～12岁视力不良儿童用10g/L阿托品眼液散瞳3d,3次/d,采用带状光检影法加主觉试镜法验光,对检查中检出的散光度≥0.50D的210只散光眼进行统计分析。结果:在3～12岁视力不良儿童210只散光眼中复性远视散光146眼占67.6%,复性近视散光占15.7%,混合散光24眼占11.4%,单纯性散光占5.3%;循规性散光占85.2%,逆规性散光占6.2%,斜轴散光占8.6%。散光程度:0.50～1.00D占54.7%,1.25～2.00D占27.6%,2.25～3.00D占11.0%,3.25～4.00D占6.7%。对称散光128眼占61.0%,不对称散光占39.0%。复性远视散光导致弱视占弱视眼75.8%(75/99);其次为混合散光占14.1%(14/99)。结论:3～12岁视力不良儿童210只散光眼中散光类型以复性远视散光多见,散光轴向分布以循规性散光为主。散光程度多在3.00D以下,散光度随着年龄增加而有下降趋势。更多还原

【Abstract】 AIM: To study the astigmatic degree and astigmatic axis distribution in the poor vision acuity children aged from 3 to 12 years old. METHODS: One percent of atropine sulfate gutta was given tid for 3 days and 210 eyes were examined by retinoscopy. To statistical analysis on 210 eyes with astigmatism of≥0.50 diopter which were detected from six- to twelve -year-old children with poor vision acuity examination. RESULTS: In astigmatism from six to twelve years old children, the ratio of compound hyperopic astigmatism was 67.6%,mixed astigmatism 11.4%; With rule direct astigmatism made up 85.2%, indirect astigmatism 6.2%, and oblique astigmatism 8.6%. Grade of astigmatism; the ratio of astigmatism of 0.50D to 1.00D was 54.7%of the astigmatism eyes, 1.25D to 2.00D 27.6%, 2.25D to 3.00D 11.0%, 3.25D to 4.00D 6.7%. CONCLUSION: Compound hyperopic astigmatism is more in six to twelve years old children’s astigmatism eyes. Direct astigmatism is mainly in distribution of astigmatism. The astigmatic degree has a trend of decreasing with ageing.更多还原
