本文对３６只儿童高度散光眼进行了角膜地形图分析观察，发现患眼屈光不正的总体散光度与其角膜前表面散光度呈正相关并有非常显著意义，总体散光度＝０．５２×角膜前表面散光度＋１．８７（ｒ＝０．８０２３，Ｐ＜０．０１）。角膜前表面不规则指数与患眼矫正视力间无相关性。本文对这些结果的临床意义以及高度散光儿童的配镜问题进行了讨论。 In this paper, 36 children with high degree of astigmatism were analyzed by corneal topography and found that the total astigmatism with refractive errors of the corneal surface astigmatism was positively correlated and has a very significant significance, the overall astigmatism = 0.52 × corneal Surface astigmatism +1.87 (r = 0.8023, P <0.01). There was no correlation between the anterior index of anterior corneal surface and eyesight corrected vision. This article discusses the clinical implications of these results and the issue of glasses for highly astigmatic children.
