目的观察翼状胬肉切除联合自体角膜缘干细胞移植治疗翼状胬肉的临床疗效。方法将80例(92眼)翼状胬肉患者随机分为治疗组38例(45眼)和对照组42例(47眼)。对照组采用传统胬肉切除治疗,治疗组采用翼状胬肉切除联合自体角膜缘干细胞移植治疗。比较2组角膜上皮愈合情况及术后复发情况。结果治疗组角膜上皮愈合速度显著快于对照组;且12个月内,治疗组复发率为2.6%显著低于对照组的31.0%,差异有统计学意义(P<0.01)。结论翼状胬肉切除联合自体角膜缘干细胞移植治疗翼状胬肉疗效可靠,复发率低,无严重手术并发症,值得推广应用。
Objective To observe the clinical effect of pterygium excision combined with autologous limbal stem cell transplantation in the treatment of pterygium. Methods Eighty patients (92 eyes) with pterygium were randomly divided into treatment group (38 eyes) and control group (42 eyes) (47 eyes). The control group received conventional pterygium excision, and the treatment group received pterygium excision combined with autologous limbal stem cell transplantation. Corneal epithelial healing and postoperative recurrence were compared between the two groups. Results The healing rate of corneal epithelium in treatment group was significantly faster than that in control group. The recurrence rate of treatment group was significantly lower than that of control group (2.6% vs. 31.0%, P <0.01). Conclusion Pterygium resection combined with limbal stem cell autologous transplantation for the treatment of pterygium with reliable curative effect, low recurrence rate and no serious surgical complications is worth popularizing and applying.
