摘要
目的探讨儿童屈光不正性弱视与散光状态的关系。方法对１７２例３１２只屈光不正性弱视眼的散光类型、散光程度和散光参差度进行统计分析。结果屈光不正性弱视的散光类型以复合远视散光最多（３０．１％），其次为复合近视散光（２４．４％）和混合散光（１８．３％）。结论导致屈光不正性弱视的散光度：单纯近视散光为１．６２±０．５２Ｄ，单纯远视散光为１．５３±０．４８Ｄ，散光参差度为１．２８±０．３３Ｄ，复合远、近视和混合散光的最低球、柱镜度数均为０．５～１．０Ｄ。
Objective To evaluate the relation between the ametropic amblyopia and astigmatism in children.Methods The typy,degree and irregularity of the astigmatism in 312 eyes of ametropia amblyopia were analysed in paper.Rusults As to the type of ametropia amblyopia in the 312 eyes,compound hyperopia astigmatism is the most(30.1%),then is compound myopia astigmatism(24.4%) and mix astigmatism(18.3%).Conclusion The astigmatic degrees that can bring about ametropia amblyopia are as follows the simple myopia astigmatism of 1.62±0.52D,the simple hyperopia astigmatism of 1.53±0.48D and the irregular degree of astigmatism of 1.28±0.33D.The lowest sphere and colum mirror degree of the compound hyperopia,myopia and mix astigmatism are all 0.5-1.0D to cause ametropia amblyopia.
