昆明市婴幼儿眼散光状态的调查研究

Research of infant astigmatism in Kunming municipality

目的 :调查和了解婴幼儿眼散光状态 ,以利于正确测定及合理矫正婴幼儿散光 ,尽早治疗和预防弱视。方法 :用托品酰胺眼液麻痹睫状肌后 ,对 1146名 1月～ 3岁婴幼儿的 2 2 91眼进行视网膜检影验光 ,并对其中的 5 6 0眼散光进行统计学分析。结果 :散光 30 3例 5 6 0眼 ,占 2 4.44 % ;其中混合散光 2 5眼 ,占 1.0 9% ;>1.0 0 D的散光为 13.75 % ,最大散光度 4.0 0 D,92 .78%为顺规散光。结论 :昆明市婴幼儿眼散光率 2 4.2 2 % ,以1.0 0 D以下的轻度散光为主。随年龄增长 ,散光逐渐减少 ,散光度逐渐减低。因此 ,实际矫治时可根据其年龄和屈光度适当减 0 .2 5～ 0 .5 0 D。

Objective:To research infant astigmatism in mass screening refraction,detecting and correcting properly infant astigmatism for the treatment and prevention of amblyopia as early as possible.Methods:The visual acuity of 1146 children(2291 eyes,1 month～3 years) were determined with retinoscopy after tropicamide cycloplegia.Results:The results of statistics show that 560 eyes(24.44%) had astigmatism and 25 eyes(1.09%) had mixed astigmatism,the grade of 13.75% astigmatism were more than 1.00D,the maxium grade of astigmatism were 4.00D,and 92.78 were direct astigmatism.Conclusion:The morbidity of astigmatism among infant in Kunming municipality were 24.44%,and most of them were low grade(<1.00D).The morbidity of astigmatism among infant in Kunming municipality were 24.44%,and most of them were low grade(<1.00D).The astigmatism and the grade of astigmatism decreased with age increase.We think that the 0.25～0.50D of astigmatism should be reduced depend up the age and the dioptry for their emmetropization.
