【摘要】 目的探讨7~15岁儿童散光眼的散光类型、散光程度及分布规律。方法从2009年8至10月间来广西壮族自治区人民医院视光门诊就诊患者中随机选择7~15岁儿童249例(498只眼),用1%复方托吡卡胺滴眼液散瞳,瞳孔散大后进行屈光度检查。结果 498只屈光不正眼中,散光眼占80.3%(400/498)。各种散光眼中,复合型近视散光最多,占50.2%,其他依次为复合型远视散光21.1%,混合散光7%。散光程度≤1.00D者占57%,≤2.00D者占22.5%,≤3.00D者占12.5%,≥3.25D者占8%。按散光轴向分,顺规散光占87.5%,逆规散光占6.5%,斜轴散光占6%。结论散光在7~15岁儿童中的检出率为80.3%,各年龄组散光分布均以低中度散光为主,7~9岁儿童以复合型远视散光为主,10~15岁儿童以复合型近视散光为主,各年龄组散轴向均以顺规散光为主。更多还原

【Abstract】 Objective To investigate the main types of astigmatism, astigmatism degree and distribution in the children aged 7~15. Methods 249 cases (498 eyes) were selected randomly in our optometry clinic patients from August to October 2009, the optometry was achieved while eye was dilated by 1% tropicamide. Results of 498 eyes of refractive errors, the eyes with astigmatism account for 80.3% (400/498). In the eyes with astigmatism, compound myopic astigmatism up to 50.2%, followed by the 21.1% compound hyperopic astigmatism and mixed astigmatism of 7%. Astigmatism ≤1.00D accounted for 57%, ≤2.00D accounted for 22.5%, ≤3.00D accounted for 12.5%, ≥3.25D accounted for 8%. According to the astigmatism axis, astigmatism with the rule, astigmatism against the rule and oblique astigmatism account for 87.5%, 6.5% and 6% respectively. Conclusion The detection rate of the astigmatism in 7~15 year-old children was 80.3%, the low to moderate astigmatism are majority in various age groups, most of the 7~9-year-old children was compound hyperopic astigmatism, however,compound myopic astigmatism constituted the most of the 10-15-year-old children,astigmatism with the rule was the most part of all age groups.更多还原
