状胬肉的临床疗效。方法137例(167眼)翼状胬肉患者随机分为A、B、C组,A组48例行单纯性翼状胬肉切除术;B组53眼行翼状胬肉切除联合新鲜羊膜移植术;C组66眼行翼状胬肉切除联合自体角膜缘干细胞移植术。术后随访6月～60月,比较各组患者术后翼状胬肉复发情况。结果A组48眼中16眼复发,复发率33.33%;B组53眼中8眼复发,为15.09%;C组66眼中3眼笔发,复发率为4.55%;A组与B组比较(χ2=4.47,P<0.05);B组与C组比较(χ2=3.90,P<0.05)差异具有显著性。结论自体角膜缘干细胞移植可有效地降低翼状胬肉术后的复发率,是目前较理想的手术方法。
Symptomatic pterygium clinical efficacy. Methods A total of 137 patients (167 eyes) with pterygium were randomly divided into A, B and C groups. A group of 48 patients underwent simple pterygium excision; B group of 53 patients underwent pterygium excision combined with fresh amniotic membrane transplantation; C Group 66 eyes underwent pterygium excision combined with limbal stem cell autografting. The patients were followed up for 6 months to 60 months and the recurrence of pterygium was compared between the groups. Results The recurrence rate was 33.33% in group A, and the recurrence rate was 33.33% in group B. The recurrence rate was 4.55% in 66 eyes of group C. The recurrence rate was 4.55% in group A and group B (χ2 = 4.47, P <0.05). There was significant difference between group B and group C (χ2 = 3.90, P <0.05). Conclusion Autologous limbal stem cell transplantation can effectively reduce the recurrence rate of pterygium surgery, which is the ideal surgical method.
