氩激光超全视网膜光凝术治疗新生血管性青光眼

Effect of extrapanretinal photocoagulation with argon laser on neovascular glaucoma

目的：评估氩激光超全视网膜光凝术对视网膜中央静脉阻塞所致的新生血管性青光眼的疗效。方法：用氩蓝绿激光对１２眼视网膜中央静脉阻塞所致的新生血管性青光眼行超全视网膜光凝术，每眼平均光凝点达２０５０点。结果：术后８例虹膜和前房角新生血管全部萎缩，４例术后眼压控制至正常水平，８例术后眼压仍高，但较术前明显下降，虽需药物或其他手术辅助降压，但全部患者的眼痛、头痛症状均有减轻或消失。结论：超全视网膜光凝术应为视网膜中央静脉阻塞所致的新生血管性青光眼的首选治疗方法，光凝越早，范围越广，效果越好。

Objective: To evaluate the effect of extrapanretinal photocoagulation with argon laser for neovascular glaucoma induced by central retinal vein occlusion. Methods: Twelve cases (twelve eyes) of neovascular glaucoma were treated by extrapanretinal photocoagulation with argon laser. The average number of photocoagulation spots of each eye was 2 050. Results: After photocoagulation, the iris and anterior chamber angle neovascularizations of 8 cases disappeared. The IOPs of 4 cases became normal. Though the IOPs of another 8 cases were still high and antiglaucoma medicines or other procedures were needed, the IOPS were much lower than that before laser treatment and the ocular pain and headache were disappeared or reduced. Conclusion: The extrapanretinal photocoagulation appears to be the first choice for neovascular glaucoma induced by central retinal vein occlusion. The earlier and more extensive the photocoagulation is, the better the effect is.
