摘要角膜上皮细胞功能障碍是指在无角膜缘细胞功能失代偿的条件下,角膜上皮细胞再生、连接、黏附及移行功能异常.由于患者自身及围手术期各种因素的影响,少数白内障患者在术后1～2周,开始出现角膜上皮水肿及角膜点状染色等,在处理不正确时,角膜上皮会发生缺损,甚至发展为迁延性溃疡.治疗的关键在于早期发现与及时正确地处理.对于有全身代谢性疾病、术前泪液异常及长期睑缘炎等情况的患者,应特别注意术后角膜上皮细胞功能障碍.

abstractsCorneal epithelial dysfunction (CED) is the abnormality of the regeneration,conjunction,adhesion and immigration of the corneal epithelium cells without the decompensation of the corneal limbal cells.Due to the affection resulting from the systemic problems of patients and the management in the preoperative period,some of the patients at one to two weeks after cataraci surgery will present the edema and fluorescein staining of the corneal epithelium.Without correct therapy,the defect of the epithelium,or even persisting ulceration of the cornea will occur.The key points of the management for CED are the early diagnosis and reasonable therapy.We suggest paying special attention to CED in the patients with metabolism diseases,abnormality of the tear film and long-term blepharitis.
