目的:探讨小梁切除术中应用可调节缝线及丝裂霉素c治疗原发性闭角型青光眼的疗效。方法:对我院收治28例(42眼)原发性闭角型青光眼应用可调节缝线联合丝裂霉素C(MMC)的小梁切除术治疗,观察术后视力、前房深度、眼压及滤过泡情况。结果:42眼闭角型青光眼术后无1例持续性浅前房,术后随诊6个月～12个月,眼压小于21mmHg有39眼,成功率92.85%。多囊滤泡37眼,占88.09%,术后视力较术前提高1行～2行者23眼,占54.76%。无变化者19眼。结论:小梁切除联合丝裂霉素c及可调节缝线术操作简便,易掌握,是治疗闭角型青光眼安全有效的方法之一。 Objective: To investigate the therapeutic effect of adjustable sutures and mitomycin C on primary angle-closure glaucoma in trabeculectomy. Methods: Twenty-eight eyes (42 eyes) of primary angle-closure glaucoma underwent trabeculectomy with adjustable suture combined with mitomycin C (MMC) in our hospital. Visual acuity, depth of anterior chamber, Pressure and filtration bleb conditions. Results: There was no persistent shallow anterior chamber in 42 eyes with angle closure glaucoma. The follow - up was 6 months to 12 months. The intraocular pressure was less than 21mmHg, and the success rate was 92.85%. There were 37 eyes with polycystic follicles, accounting for 88.09%. Postoperative visual acuity was improved by 1 line ~ 2 lines in 23 eyes, accounting for 54.76%. No change in 19 eyes. Conclusion: Trabeculectomy combined with mitomycin C and adjustable suture operation is simple and easy to master. It is one of the safe and effective methods to treat angle-closure glaucoma.
