目的比较评价新鲜羊膜移植与自体角膜缘移植在翼状胬肉治疗中的效果。方法翼状胬肉患者42例48眼。分为羊膜移植组及角膜缘移植组,每组24眼。分别行翼状胬肉切除联合新鲜羊膜移植和自体角膜缘移植。术后随访12～19个月,观察翼状胬肉复发率。结果羊膜移植组6眼(26%)复发,角膜缘移植组3例(13.6%)复发。在初发性胬肉治疗中两组分别有3眼(20%)、2眼(14%)复发;在复发性胬肉治疗中两组分别有3眼(37%)、1眼(12.5%)复发。结论在防止胬肉复发方面,羊膜移植与角膜缘移植在治疗初发性胬肉中疗效相当;角膜缘移植治疗复发性胬肉疗效优于羊膜移植。
Objective To evaluate the effect of fresh amniotic membrane transplantation and limbal autograft in the treatment of pterygium. Methods 42 cases of pterygium patients 48 eyes. Divided into amniotic membrane transplantation group and limbal transplantation group, 24 eyes in each group. Pterygium excision combined with fresh amniotic membrane transplantation and autologous limbal transplantation. The patients were followed up for 12-19 months and the recurrence rate of pterygium was observed. Results In the amniotic membrane transplantation group, 6 eyes (26%) relapsed and 3 cases (13.6%) in the limbal graft group relapsed. There were 3 eyes (20%) and 2 eyes (14%) in the two groups, respectively. In the treatment of recurrent pterygium, there were 3 eyes (37%), 1 eyes (12.5% )relapse. Conclusion Amniotic membrane transplantation and limbal transplantation in the treatment of primary pterygium in the prevention of recurrence of pterygium has the same effect; limbal transplantation for the treatment of recurrent pterygium better than amniotic membrane transplantation.
