目的比较单纯小梁切除术与联合小梁切除术的成功率及并发症。方法８４例（９８眼）原发性青光眼随机分成３组，第１组行单纯小梁切除术；第２组行小梁切除联合可拆除缝线术；第３组行小梁切除术中联合丝裂霉素。术后平均随访时间为１８４月。结果手术成功率分别为：单纯小梁切除组（２１／３２，６５．６％），可拆除缝线组（２８／３２，８７．５％），丝裂霉素组（３２／３４，９４１％）。并发症发生率：单纯小梁切除组＞可拆除缝线组＞丝裂霉素组。结论联合小梁切除术较单纯小梁切除术成功率高而并发症发生率低。
Objective To compare the success rate and complications of simple trabeculectomy and trabeculectomy. Methods 84 cases (98 eyes) of primary glaucoma were randomly divided into 3 groups, group 1 trabecular surgery alone; group 2 trabeculectomy with removable suture; group 3 trabeculectomy combined Mitomycin. The average follow-up time was 18 April. Results The successful rates of surgery were as follows: simple trabeculectomy group (21/32, 65.6%), detachable suture group (28/32, 87.5%), mitomycin group (32/34, 94 1%). Incidence of complications: simple trabeculectomy group> detachable suture group> mitomycin group. Conclusions Combined trabeculectomy has a higher success rate and lower complication rate than trabeculectomy alone.
