弱视儿童散光变化的动态检测

The Dynamic Studies of the Astigmatic Changes of Amblyopic Children

对395例（612眼）3～12岁弱视儿童散光变化进行了动态检测，进一步了解了弱视儿童的散光变化规律。全部病例球镜的主要变化为远视度数减少或近视度数增加（75％）。激光的主要变化为：复性远视散光大部分转变为单纯远视激光（44％），单向转变占25％；混合性激光大部分单向转变（63％）。散光轴位无变化420眼（68．6％），激光的屈光度大部分没有改变，且以规则性散光为主。本文并对产生原因及激光变化的意义进行了详细讨论。

The dynamic studies were made of the cycloplegic astigmatic changes of 395 cases (612 eyes ) amblyopic children,3-12 years of ages. During development there was decrease in the degree of hypermetropia of increase in the degree of myopia (75% ) on the major spherical changes of all cases. Most compound hypermetropic astigmatism changed into simple hypermetropic astigmatism (44% ), 25% were changes of single way and most mixed astigmatism were changes of single way (63% ) on the major astigmatic changes. There was no change in the astigmatic axis of 420 eyes (68. 6% )and the majority of cylindrical refraction (dioptres ), moreover the major astigmatic eyes were direct astigmatism.The significance and cause of cycloplegic astigmatic changes in amblyopic children were discussed.
