Corneal fissure which had not closed well lead to corneal fistula, with corneal epithelial ingrowth, hernia of iris and vitreous, and large area of tissue defect in the center area of the cornea as its common etiology. 角膜伤口闭合不良者易形成角膜瘘,常见原因为角膜上皮细胞内卷,虹膜和玻璃体嵌顿,角膜伤口处组织缺损较大且位于角膜中央。
Conclusions The modified suction ring is safe and effective for those eyes with flat cornea, small corneal diameter and small palpebral fissure. 结论国产改良负压吸引环对于较平的角膜、角膜直径偏小以及睑裂偏小等特殊患者是一种安全有效的负压吸引固定环。
Methods 117 specimens of enucleated eyeball were observed by light microscopy, among which 18 cases of corneal fissure after ocular contusion, 99 cases of corneal perforation. 方法对因角膜外伤后摘除眼球标本117例进行光镜观察,其中因眼挫伤致角膜裂伤18例,角膜穿孔伤99例。
