小梁手术的结膜瓣以往一般都采用以角膜缘为基底的方法,考虑到术后滤过孔有结膜和巩膜双重瓣膜的复盖,直接阻碍房水的眼外引流近年来随着眼科显微手术的普及推广,国内外众多学者,均渐采用以穹窿部为基底的经角膜缘结膜切开法进行小梁手术。笔者在手术显微镜(10～25×)、部份病例在双目手术放大镜(4×)下采用这种方法选择性地对几种常见类型的青光眼42例(54眼)分别进行了小梁切开、小梁切除、小梁切除联合巩膜下虹膜嵌顿、小梁切除联合白内障摘除等手术(表1)。其中男性18例、女性24例、年龄最小为8个月、最大年龄为
Trabeculectomy conjunctival flap traditionally used in the limbal-based approach, taking into account the postoperative filtration holes conjunctival and scleral double valve coverage, a direct impediment to aqueous humor drainage in recent years with ophthalmic microscopy The popularization of surgery, many scholars at home and abroad, are gradually using the fornix-based corneal conjunctival incision trabeculectomy. In the surgical microscope (10 ~ 25 ×), some cases in the binocular surgical magnifying glass (4 ×) using this method selectively several common types of glaucoma in 42 cases (54 eyes) were trabeculectomy Open, trabeculectomy, trabeculectomy with scleral iris incarceration, trabeculectomy combined with cataract surgery (Table 1). Among them, 18 were males and 24 females, the youngest was 8 months and the oldest was
