复发性翼状胬肉手术治疗的临床观察

Clinical observation of surgical treatment of the recurrent pterygium

目的探讨复发性翼状胬肉的手术方法和临床效果。方法采用复发性翼状胬肉手术切除联合角膜缘干细胞移植术46例（46眼）,术后给予丝裂霉素C滴眼液预防复发等治疗。观察术前术后视力、结膜瓣植片以及角膜情况等。术后随访6个月以上。结果 46眼术后视力均有不同程度提高,≥0.3者7眼（15.22%）,0.4~0.8者30眼（65.21%）,≤1.0者9眼（19.57%）。治愈45眼（97.83%）,复发1眼（2.17%）。无严重并发症发生。结论采用胬肉手术切除联合角膜缘干细胞移植术以及术后给予丝裂霉素C滴眼液治疗复发性翼状胬肉方法简单,手术安全,疗效良好,适合基层医院开展。

Objective To explore the surgical method and clinical efficacy of the recurrent pterygium. Methods Forty-six patients（ 46 eyes） with the recurrent pterygium were given the excision of pterygium combined with corneal limbus stem cell transplantation,and postoperatively treated with mitomycin C eye drops to prevent recurrence. The preoperative and postoperative visual acuity,corneal situation,conjunctival flap and recurrence rate were observed. The patients were followed up more than 6months. Results The postoperative visual acuity of all cases was improved in different degrees. There was ≤0. 3 in 7 eyes（ 15. 22%）,0. 4-0. 8 in 30 eyes（ 65. 21%）,≥1. 0 in 9 eyes（ 19. 57%）. Forty-five eyes（ 97. 83%） recovered after surgery,1 eye（ 2. 17%） relapsed. There was no severe complications occurred. Conclusion The treatment method of the excision of the recurrent pterygium combined with corneal limbus stem cell transplantation and the mitomycin C eye drops treated postoperatively is simple and safe. Postoperative visual was good. It is convenient to be used in primary hospital.
