角膜软化症是缺乏维生素A引起角膜与结膜上皮的干燥性变性,角膜基质崩溃和坏死。其病理改变在光学显微镜下:角结膜干燥时,上皮角化,上皮细胞均匀一致,细胞边界及核不能看出,表层上皮细胞內有透明角质小球?悄と砘?角膜基质小板广泛坏死,继以脱落。本文报告一例角膜软化后角膜葡萄肿并发眼内炎,眼球摘出后进行扫描电镜观察的结果。一、临床资料王从元,男,10岁。住院号:15837。左眼痛、纳呆半月入院。1岁时,曾腹泻三个月。腹泻二十余天时,双眼出现“翳子”。此后,左眼失明,常痛痒。检查:右眼正
Corneal softening is the lack of vitamin A causes corneal and conjunctival epithelial dry degeneration, corneal stroma collapse and necrosis. The pathological changes in the optical microscope: the angle of the conjunctiva dry, epithelial keratosis, epithelial cells are uniform, the cell boundaries and nuclei can not see the surface epithelial cells with transparent keratinocytes? Necrosis, followed by loss. This article reports a case of corneal degeneration of corneal staphyloma complicated with endophthalmitis, the results of scanning electron microscopy after enucleation. First, the clinical data Wang Congyuan, male, 10 years old. Hospital number: 15837. Left eye pain, half a month admitted to hospital. 1 year old, had diarrhea for three months. Diarrhea more than twenty days, his eyes appear “prickly heat”. Since then, the left eye blindness, often itchy. Check: right eye is positive
