The morphlogic change of the lens capsule in patients with congenital cataract

目的 探讨晶体囊膜的形态学特点及与先天性白内障的关系。方法 对患有先天性白内障的26人41眼进行临床形态学观察。结果 有晶体囊膜异常的病例占总数的39.0%，大部分在半岁内发病，多数合并有小眼球、青光眼、虹膜异常、晶体后纤维增生症、永存增生性原始玻璃体(PHPV)、小晶体等先天异常。眼轴越短的眼有囊膜病变的几率越高。结论 本结果提示晶体囊膜的形成与白内障的发生及眼球的发育密切相关。Object To investigate researched the morphologic change of thelens capsule and the relationship with congenital cataract. Method We reviewed records of 41 eyes of 26 patients with congenital cataract. They were undergone the cataract extraction between April. 1998 and October. 1999. The mean age of them was 2.5 years. (2 months～12years), 16 male and 10 female. The morphologic characteristics of the lens were observed with slit-lamp or operating microscope. Result 39.0% of all cases have the pathological changes of the lens capsule. In the most of them, cataract often happens in the 6 months of age and majority of the eyes were combined with multifarious congenital abnormalities, such as microphthalmus、 glaucoma、 PHPV、 microcrystal and so on. The shorter the ocular axial lengths is, the more odds of lens capsule abnormalities is. Conclusion The dysgenesis of lens capsule is intimately correlated with congenital cataract.018-10
