手术操作和外伤对角膜内皮均有损伤。作者用角膜内皮显微镜检查12例不同大小的角膜裂伤或角巩膜裂伤患者,以阐明角膜伤口长度与内皮细胞丢失的关系,以期预测再次手术时角膜失代偿的危险性。材料与方法:作者检查了1985～1990年所有眼外伤患者230例,除外没有角膜裂伤,或有角膜裂伤但已做过眼球摘除或穿透性角膜移 Surgery and trauma are all corneal endothelial damage. The authors used corneal endothelial microscopy in 12 patients with corneal laceration or scleral laceration of different sizes to clarify the corneal wound length and endothelial cell loss in order to predict the risk of corneal decompensation during reoperation. Materials and Methods: The authors examined 230 patients with all eye trauma from 1985 to 1990 except for no corneal laceration or corneal laceration but had enucleated or penetrating keratoplasty
