3～11岁视力低常儿童散光与弱视分析

目的探讨3~11岁儿童弱视散光类型、散光度分布、散光轴分布、双眼散光轴关系、散光轴与弱视的关系。方法对门诊3~11岁视力低常儿童266例(503只眼)散光状况进行统计分析。结果复性远视散光居多,占71.07%,依次为复性近视散光11.53%,混合散光8.95%,单纯远视5.17%,单纯近视散光3.18%。散光程度0.50~1.00DC占52.18%,依次为1.25~2.00DC占30.02%,2.25~3.00DC占10.54%,>3.00DC占6.76%。顺规散光占94.23%,逆规散光占2.19%,斜向散光占3.58%。双眼散光中,对称散光占95.43%,不对称散光占4.57%。双眼散光占89.46%,单眼散光占10.54%。结论远视性散光是儿童散光的主要类型,顺规散光为主,双眼散光以对称散光多见,散光与弱视关系密切,科学合理矫正儿童散光眼,有利于儿童弱视防治。

Analysis of astigmatism and amblyopia in children aged from 3 to 11 years whose visual acuity(VA)is declined

Objective To investigate the type of astigmatism and amblyopia, distribution rule of astigmatism degree ,distribution rule axis of astigmatism , the relationship between two eyes axis of astigmatism , the relationship between axis of astigmatism and amblyopia in children aged 3~11 old.whose visual acuity(VA)is declined. Methods 266 cases 503 eyes of astigmatism in children aged from 3 to 11 years whose visual acuity declined were analysised statistically. Results the ratio of compound hypermetropic astigmatism is predominant,is 71.07%, then compound myopic astigmatism is 11.53%,mixed astigmatism is 8.95%,simple hypermetropia is 5.17%, simple brachymetropia is 3.18%. astigmatism degree 0.50 DC~1.00 DC is 52.18%,1.25 DC~2.00 DC is 30.02%, 2.25 DC ~ 3.00 DC is 10.54%,>3.0 DC is 6.76%.The ratio of astigmatism with rule is 94.23%,astigatism against the rule is 2.19%, oblique astigmatism is 3.58%. Symmetrical astigmatism is 95.43%,asymmetrical astigmatism is 4.57%in the binoculus astigmatism .The binoculus astigmatism is 89.46%,monoculus astigmatism is 10.54%. Conclusion The main tyre of astigmatism of children is hypermetropic astigmatism, astigmatism with rule is predominant. Symmetrical astigmatism is predominant in the binoculus astigmatism. There is an association between astigmatism and amblyopia.
