睫状体冷冻联合小梁切除术治疗晚期新生血管性青光眼

目的　探讨睫状体冷冻联合小梁切除术治疗晚期新生血管性青光眼的疗效。方法　对 2 2例 2 2眼不同原因引起的新生血管性青光眼采取该术式 ,以降低眼压 ,解除症状 ,术后随访 3～ 36个月。结果　术后各眼视力基本保持不变 ;眼压控制在 6 .46～ 2 0 .5 5 m m Hg(1k Pa=7.5 mm Hg)者 12眼(5 4.5 % ) ;2 0 .5 5～ 2 8.0 1mm Hg者 5眼 (2 2 .7% )配合眼球按摩后眼压下降 ;眼压 >2 8.0 1mm Hg者 4眼 (18.2 % ) ;<6 .46 mm Hg者 1例 ,术后 1a眼球萎缩。眼部刺激症状消失或减轻者 19眼 (86 .3% ) ,不能缓解者 3眼 (13.6 % ) ,于术后 2～ 6个月行眼球摘除术。虹膜表面及瞳孔缘新生血管均减少 ,13眼 (5 9% )术后 0 .5 a冷冻区域新生血管消失。结论　对于较晚期视功能差 ,眼部不适症状明显的新生血管性青光眼采用本术式可有效控制眼压 ,缓解症状 ,减少眼球摘除机会

Cyclocryotherapy and trabeculectomy for late neovascular glaucoma

Objective To evaluate the efficacy of cyclocryotherapy and trabeculectomy in the treatment of neovascular glaucoma.Methods Twenty-two cases(22 eyes) of neovascular glaucoma caused by different diseases were treated with cyclocryotherapy and trabeculectomy in order that their intraocular pressures (IOP) were reduced and symptoms were relieved. After operation, 22 cases were followed up period of 3~36 months averaging 18 months.Results Postoperative visual acuity remained unchanged. The IOP in 6.46~20.55 mmHg (1kPa=7.5mmHg)was in 12 eyes (54.5%),in 20.55~28.01 mmHg was in 5 eyes(22.7%) and the IOP over 28.01 mmHg was in 4 eyes (18.2%), below 6.46 mmHg was in 1 eye.The stimulative symptoms were reduced or relieved in 19 eyes (86.3%)and the neovascular net on iris was reduced, most of them disappeared after 6 months. No efficacy was obtained in 3 eyes. These 3 eyeballs were extraction after operation 2 to 6 months. Conclusion Cyclocryotherapy and trabeculectomy can control the IOP, relieve the symptoms and reduce the chance of eyeball extraction in the patients with neovascular glaucoma.
