角膜混浊[1][2](corneal opacity)、角膜浑浊[3]角膜失透(corneal opacification),在汉语中,均指角膜失去原有的透明性。但英语 corneal opacity 较为偏向角膜因瘢痕形成而失去透明度,此时汉语可称角膜斑[4]

任何发生于角膜的炎症、水肿以及瘢痕均会导致角膜混浊,角膜混浊会造成视力障碍以及失明[5]。而且有人患有先天性角膜混浊[6]。另外人死后角膜内层细胞自溶房水进入角膜中层,角膜出现乳白色云雾状斑块。法医会用角膜混浊程度来判断死亡时间。通常人死后6~12小时角膜轻度混浊,15~20小时角膜中度混浊,死后24小时左右角膜高度混浊,此时瞳孔已无法看清[7]
