氪激光治疗视网膜静脉阻塞的新生血管

Krypton laser treatment of neovascularization in retinal vein occlusion

目的 探讨氪激光治疗视网膜静脉阻塞新生血管的方法和疗效。 方法 对 2 7例视网膜静脉阻塞伴有新生血管的 2 8只患眼采用氪绿、氪红激光进行光凝治疗。光凝后经 6个月～ 2 .5年随访 ,对比分析光凝前后的荧光素眼底血管造影及视力变化情况。 结果 新生血管萎缩 2 0只眼 ,占 71.4% ,好转 6只眼 ,占 2 1.4% ,无效 2只眼 ,占 7.2 %。视力进步 17只眼 ,占 6 0 .7%。 结论 氪激光光凝术对视网膜静脉阻塞新生血管的消退及预防其玻璃体积血具有显著疗效。

Objective To investigate the method and effect of krypton laser photocoagulation for neovascularization in retinal vein occlusion. Methods Tweenty eight eyes of 27 patients with retinal vein occlusion with neovascularization were photocoagulated by krypton-green and-red laser.The fundus changes were observed by fundus fluorescein angiography after photocoagulation. Results The neovascularization disappeared completely in 20 eyes and became smaller in 6 eyes,remained no-change in 2 eyes,and the visual acuity improved in 17 eyes (60.7%) after 6 monthes to 2.5 years of follow-up. Conclusion Krypton laser photocoagulation is obviously effective on regression of neovascularization and prevenion of vitreous hemorrhage in retinal vein occlusion.
