目的:观察角膜缘干细胞移植治疗翼状胬肉的临床疗效。方法:对40例45眼翼状胬肉患者行角膜缘干细胞移植术。观察术后角膜上皮修复,角膜缘新生血管及翼状胬肉复发情况。结果:术后随访5～48mo,42眼植片透明光滑,无异常胬肉样组织增生,3眼复发。复发率7%,治愈率93%。结论:角膜缘干细胞治疗翼状胬肉可有效防止翼状胬肉复发,具有复发率低的优点,是目前治疗翼状胬肉的一种安全有效的方法。

AIM:To investigate clinical effect of corneal limbal stem cell transplantation for treatment of pterygium.METHODS:Totally 45 eyes of 40 patients with pterygium were treated by limbal stem cell transplantation.Postoperative corneal epithelial healing,corneal neovas-cularization and pterygium recurrence were observed.RESULTS:The patients were followed up for 5-48 months.42 eyes had clear and smooth graft,no abnormal proliferation of pterygium tissue;3 eyes recurred.Recurrence rate was 7%,the cure rate was 93%.CONCLUSION:The limbal stem cell transplantation for treatment of pterygium can prevent its recurrence with the advantage of a low recurrence rate,and it is a safe and effective method.
