氪激光治疗视网膜静脉阻塞的新生血管

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27例视网膜静脉阻塞伴有新生血管的28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20只眼，占71.4％，好转6只眼，占21.4%，无效2只眼，占7.2%。 视力进步17只眼，占60.7%。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。(中华眼底病杂志,2001,17:12-14)

Krypton laser treatment of neovascularization in retinal vein occlusion

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.
