目的 :探讨定量滤过性小梁切除术的方法及疗效。方法 :将 14 5例 (180只眼 )原发性青光眼随机分为A、B、C组 ,每组均为 6 0只眼。A组行小梁切除联合调整缝线 ;B组行小梁切除联合MMC ;C组行小梁切除联合MMC及调整缝线。观察术后眼压、视力、滤过泡、前房、眼底等。结果 :随访 1年 ,手术成功率A组为 81 7% ,B组为 93 3% ,C组为 96 7%。B、C两组与A组对比有显著差异。低眼压、浅前房、脉络膜脱离、黄斑水肿、视力下降等并发症 ,A、C两组较B组显著减少。结论 :C组方法既能抑制瘢痕化又可避免术后早期超滤过引起的并发症 ,可定量改善滤过。
Objective: To explore the method and efficacy of quantitative filtration trabeculectomy. Methods: 145 cases (180 eyes) of primary glaucoma were randomly divided into A, B, C groups, each group of 60 eyes. Group A trabeculectomy combined with adjustment sutures; Group B trabeculectomy combined with MMC; Group C trabeculectomy combined with MMC and suture adjustment. Postoperative intraocular pressure, visual acuity, filtration bleb, anterior chamber, fundus and so on. Results: After one year of follow-up, the successful rate of operation was 81 7% in group A, 93 3% in group B and 96 7% in group C, respectively. B, C two groups compared with the A significant difference. Low intraocular pressure, shallow anterior chamber, choroidal detachment, macular edema, visual acuity and other complications, A, C two groups were significantly reduced compared with the B group. Conclusion: The method of group C can not only inhibit scarring but also avoid complications caused by early ultrafiltration, which can improve the filtration quantitatively.
