小梁切除术与联合小梁切除术的临床疗效比较

A clinical comparison of trabeculectomy with combined trabeculectomy

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１８４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（３２／３４，９４１％）。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 successful rates and complications between trabculectomy and combined trabeculectomy. Methods 98 eyes of 84 cases with primary glaucoma were divided into three groups. The first group(32 eyes):trabeculectomy was done in usual manner;the second group (32 eyes):trabeculectomy was done with combining removable suture;and the third group:(34 eyes)trabeculectomy was done with combining mitomycin C(MMC).These cases were followed up for 12～28 months (mean 18.4 months). Results The IOPs were controlled within normal limit in 65.6% for the first group,87.5% for the second group,94.1% for the third group( P <0.05).The incidence of ocular complications was significantly lower in the second and the third group. Conclusion Combined trabeculectomy has higher successful rate and lower complications than single trabeculectomy.
