保存视力和控制眼压是新生血管性青光眼治疗中尚未解决的难题。作者对24只不同病因所致的新生血管性青光眼行滤过性手术,在这两方面均取得较好效果。患眼均为眼压高伴有小梁新生血管,360°周边前粘连,房角全部或大部关闭,术前眼压平均42mmHg,药物不能控制,视力从20/40到光感。手术方法分小梁切除术和后唇巩膜切除术两种。首先在颞下方角膜缘内作前房穿刺切口(以便恢复前房,冲洗前房出血),然后在上方距角膜缘12mm处切开结膜,分离结膜瓣直达角膜缘,严格止血并剪去球筋膜。在小梁切除术中,用刀片作一1/2巩膜厚度的三角形或长方 Preserving vision and controlling intraocular pressure are unresolved problems in the treatment of neovascular glaucoma. The author of 24 different causes of neovascular glaucoma filterability surgery, both in terms of better results. Patients with high intraocular pressure are associated with trabecular neovascularization, 360 ° peripheral adhesions, all or most of the angle closure, preoperative intraocular pressure average 42mmHg, the drug can not be controlled, visual acuity from 20/40 to light perception. Surgical methods divided trabeculectomy and posterior lip sclerectomy two. First in the temporal corneal margin of the anterior chamber puncture incision (in order to restore the anterior chamber, flushing the anterior chamber hemorrhage), and then from the top of the limbal incision 12mm at the conjunctiva, conjunctival flap directly to the corneal margin, strict stop bleeding and the corpus fascia . In trabeculectomy, a blade is used to make a triangle or rectangle of 1/2 scleral thickness
