本组男14例,女6例;年龄38～69岁。术前视力无光感,眼压为4.60～10.89kPa。有糖尿病12例,视网膜静脉阻塞8例。术后恢复正常眼压以下18例,有效率90%。2例眼压不降者,不愿行二次手术,摘除眼球。观察6个月无眼球痨。 方法:局麻下沿角膜缘下方自3点至9点扇形切开球结膜,分离暴露内外直肌。将肌健、肌纤维分上、下各半,分别结扎,肌健、肌纤维,结扎相距3mm。冷冻器在下方睫状体突部角、巩膜上冻6～7个点,温度-80℃,时间60秒。缝合球结膜,结膜下注射庆大霉素、地塞米松。术后口服醋氮酰胺、消炎痛,拆线后用消炎痛眼水点眼。 讨论:晚期新生血管性青光眼由于虹膜表面及房角有大量新生血管网,行各种滤过性手术引流效
The group of 14 males and 6 females; aged 38 to 69 years. No preoperative visual acuity, intraocular pressure was 4.60 ~ 10.89kPa. There are 12 cases of diabetes, retinal vein occlusion in 8 cases. Postoperative normal pressure to restore the following 18 cases, the effective rate of 90%. 2 cases of intraocular pressure is not down, unwilling to line the second surgery, removal of the eye. Observation of 6 months without eyeball 痨. Methods: under local anesthesia along the corneal margin from 3 o’clock to 9 o’clock fan cut the conjunctiva, the separation of the medial and lateral rectus muscles. The muscle-building, muscle fiber points on the next half, respectively, ligation, muscle-building, muscle fibers, ligation 3mm apart. Frozen ciliary body in the lower corner of the angle, sclera frozen 6 to 7 points, the temperature -80 ℃, time 60 seconds. Suture conjunctiva, conjunctival injection of gentamicin, dexamethasone. Postoperative oral acetazolamide, indomethacin, stained with indomethacin eye drops. Discussion: advanced neovascular glaucoma because of the iris surface and a large number of angina neovascularization, a variety of drainage surgery drainage effect
