目的 :角膜缘干细胞移植术与结膜瓣移植术治疗翼状胬肉的疗效比较 ,寻找低复发率的治疗方法。方法 :6 8例 (73眼 )非复发性、复发性翼状胬肉及化学烧伤后的假性胬肉 ,分别进行胬肉切除加自体带蒂结膜瓣移植或角膜缘干细胞移植术 ,术后观察两组的泪膜破裂时间 BUT、角膜上皮修复时间 ,以及复发率。结果 :对非复发性胬肉 ,两组间各项指标比较无统计学差异 ;对复发性胬肉、化学烧伤后的假性胬肉 ,角膜上皮修复时间比较无显著差异 ,但角膜缘干细胞移植术的复发率明显低于结膜瓣组 ,BUT恢复快。结论 :对复发性胬肉及化学烧伤后的假性胬肉 ,角膜缘干细胞移植术的效果优于结膜组 OBJECTIVE: To compare the curative effect of limbal stem cell transplantation and conjunctival flap transplantation in the treatment of pterygium, and to find the treatment method of low recurrence rate. Methods: Sixty-eight cases (73 eyes) of non-recurrent and recurrent pterygium and pseudo-pterygium after chemical burns were performed resection of pterygium and autologous pedicle conjunctival flap transplantation or limbal stem cell transplantation, postoperative observation The tear film breakup time BUT, corneal epithelial repair time, and recurrence rate were compared between the two groups. Results: For non-recurrent pterygium, there was no significant difference in the indexes between the two groups. There was no significant difference in the repair time between recurrent pterygium, pseudobulb after chemical burns and corneal epithelium, but limbal stem cell transplantation The recurrence rate was significantly lower than the conjunctival flap group, BUT faster recovery. Conclusion: The effect of limbal stem cell transplantation on recurrent pterygium and pseudobulb after chemical burn is better than that of conjunctiva group
