为了解可拆式巩膜瓣缝线是否能有效地减少小梁切除术后并发症。以６５例原发性慢性闭角型青光眼（１０５眼）为对象。前６个月，３４例病人（４８眼）接受标准小梁切除术；后６个月，３１例病人（５７眼）接受可拆式巩膜瓣缝线小梁切除术。术后一天、七天、一月及一年，检查比较两组滤过泡、前房深度、眼压、视力和眼底情况。结果：在可拆式巩膜瓣缝线小梁切除术组，术后早期Ⅱ—Ⅲ度浅前房和视力下降的发生率分别为３．５１％和１０．５３％；而在标准小梁切除术组，为１６．６７％和２９．１７％（Ｐ＜０．０１）。而且，术后前房轴深减少值与术后一天眼压成直线负相关关系。结论：小梁切除术后超滤过是前房形成迟缓和低眼压性黄斑病变的主要原因。可拆式巩膜瓣缝线小梁切除术能有效控制术后滤过水平，从而减少因超滤过所引起的术后并发症。
To understand whether the detachable scleral suture can effectively reduce post-trabecular surgery complications. To 65 cases of primary chronic angle-closure glaucoma (105 eyes) as the object. In the first 6 months, 34 patients (48 eyes) underwent standard trabeculectomy; after 6 months, 31 patients (57 eyes) received detachable scleral suture trabeculectomy. One day, seven days, one month and one year after operation, we compared the two groups of filtration bleb, anterior chamber depth, intraocular pressure, visual acuity and retinal status. Results: In the detachable scleral flap trabeculectomy group, the incidence of postoperative Ⅱ-Ⅲ shallow anterior chamber and visual acuity were 3.51% and 10.53% respectively; while in the standard trabeculectomy The surgery group was 16.67% and 29.17% (P <0.01). Moreover, postoperative anterior axial depth reduction and intraocular pressure after a day into a linear negative correlation. CONCLUSIONS: Ultrafiltration after trabeculectomy is a major cause of delayed formation of anterior chamber and macular degeneration. Removable scleral suture trabeculectomy can effectively control the level of postoperative filtration, thereby reducing the complications caused by ultrafiltration complications.
