目的探讨晚期青光眼小梁切除术的成功率。方法对34例（36眼）晚期青光眼行小梁切除术，术中用0．2mm.ml丝裂霉素及巩膜瓣密缝技术，术后平均随访17．5月。结果术后1年眼压控制率（＜21mmHg）为91．7%，＜15mmHg者占83．31%。术后并发症也较少发生。结论小梁切除术术中联合应用丝裂霉素能提高晚期青光眼患者的手术成功率，较好地保存患者残余视功能。
Objective To investigate the success rate of trabeculectomy in advanced glaucoma. Methods Thirty-four patients (36 eyes) with advanced glaucoma underwent trabeculectomy. The patients were treated with 0.2mm.ml mitomycin C and scleral flap seams. The average follow-up was 17.5 months. Results One year after operation, the intraocular pressure control rate (<21mmHg) was 91.7%, and those with <15mmHg accounted for 83.31%. Postoperative complications occur less frequently. Conclusion Mitomycin combined with trabeculectomy can improve the success rate of surgery in patients with advanced glaucoma and better preserve the residual visual function.
