目的 调查分析近期东北地区角膜移植患者的致病原因。方法 选择符合角膜移植手术适应症标准并行穿透或板层角膜移植的2 5 4例病例,分析角膜移植病人的致病原因。结果 目前角膜移植术适应症主要以各种原因导致的角膜白斑71例居首位,约占2 8 .0 % ,其中病毒性角膜病导致的角膜白斑2 9例,约占4 0 . 8%。年龄分布以中青年组为主。结论 角膜白斑是东北地区角膜移植的主要病因,其中真菌性逐年增多,病毒性逐年减少,但病毒性角膜病导致的角膜白斑居多,预防角膜白斑的形成,可有效地降低临床角膜移植率
Objective To investigate the causes of corneal transplantation in northeast China. Methods Twenty-five cases were selected in accordance with the standard indications of keratoplasty and standard corneal transplants or lamellar keratoplasty. The causes of corneal transplantation were analyzed. Results At present, the indications for corneal transplantation mainly include 71 cases of corneal leucoma caused by various reasons, accounting for 28.0%, of which 29 cases are caused by viral keratopathy, accounting for 40.8% . The age distribution mainly in middle-aged group. Conclusions Leukoplakia is the main cause of corneal transplantation in Northeast China. The fungality is increasing year by year, while the virus is decreasing year by year. However, the majority of corneal leukoplakia caused by viral keratopathy prevents the formation of corneal leukoplakia, which can effectively reduce the clinical corneal graft rate
