目的:采用前瞻性随机对照的方法观察三种方法治疗复发性翼状胬肉的疗效。方法:对两中心自1999年7月-2002年7月施行的复发性翼状胬肉80例(81眼),男37例(37眼),女43例(44眼),年龄为39-72岁,平均年龄53.42岁,随机分三组, A组:自体角膜缘与结膜移植30例30眼,B:组单纯胬肉切除+Sr90照射22例22眼,C组:单纯胬肉切除+术中应用MMC(浓度为0.2mg/ml) 28例29眼,三组无性别及年龄的差别,翼状胬肉侵入透明角膜内2~7mm不等,所有病例无局部活动性角膜或巩膜的炎症,其中有2例2眼为颞侧发病,其余均为鼻侧发病,随访6月-2年,(其中失访5例)。判定指标 1. 术后1天、3天、7天在裂隙灯显微镜下观察其术后反应包括患眼局部水肿、流泪异物感二指标之和为记分。水肿根据程度分无水肿为0、角膜缘处可见结膜水肿皱折为1、结膜水肿明显高出角膜为2分、结膜水肿部分或全部突出于睑裂外为3分;无异物感的为0分,可正常的生活学习的为1分,影响学习和生活不原睁眼的为2分,刺激症状较重难以睁眼的为3分。2. 复发情况(复发的判定指标为纤维血管组织再次跨过角膜缘为标准)。所有手术均由技术操作熟练的医生完成,并有中心专人负责观察记录术后的随访情况,一周内每天复查,术后15天、1月、3月、6月、1年、2年常规裂隙灯显微镜复查。应用SPSS统计软件q检验及卡方检验进行统计学处理。结果 术后1天A组反应较B、C组重( P=0.0432),术后3天、7天A组与其他无显著性差异(P=0.152,P=0.523);角膜愈合时间三组均在第二次复诊时上皮完全愈合;术后2年复发率三组间有差异有显著性(P=0.037),A组复发率明显为低。结论 角膜缘干细胞移植是治疗复发性翼状胬肉较为理想的方法。

Abstract
Objective To compare the therapeutic effect of three different kinds of surgical methods to treat recurrent pterygium. Methods 80 cases (81 eyes) of patients with recurrent pterygium were randomly divided into three groups. We treated group A with autograph transplantation with limbus stem cells; exposed group B to Sr90 5 to 7 days after resected for three times; contacted the surface of sclera in group C with tampon dipped in MMC(0.2mg/ml) solution 3 minutes after resected. And compare the effect between every two groups. Results Reaction after operation in group A is more severe than group B or C( P=0.0432) one day after operation, but three days later they are the same. Cornea hurling in all groups , and the ratio of recurrence in group A is lowest during a two-year follow-up. Conclusions Autograph transplantation with limbus stem cells is a relatively ideal method to treat recurrent pterygium.
