氪激光治疗视网膜分支静脉阻塞临床分析

Krypton yellow laser photocoagulation treatment of branch retinal vein occlusion

目的 探讨氪黄激光治疗视网膜分支静脉阻塞的方法和疗效。方法 对 5 6例视网膜分支静脉阻塞采用氪激光进行治疗。光凝后经 1～ 3 2个月随访观察视力 ,眼底荧光造影及并发症情况。结果 视力增加者 3 5眼 ,占 62 5 % ;不变者 3 0例占3 7 5 % ,激光治疗后视力 0 5以上者 2 9例 ,占 5 1 78%。激光治疗后黄斑水肿明显减轻和消退者 3 0例 ,占 76 47%。

Objective To investigate the effect of krypton laser photocoagulation on branch retinal vein occlusion. Methods All of 56 patients with branch retinal vein occlusion were photocoagulated by krypton laser. The patients were followed up for 5 to 32 months. The fundus changes and complications were observed by fundus fluorescein angiography after photocoagulation. Results The visual acuity improved in 35 eyes(62 5%). The visual acuity surpassed 0 5 in 29 eyes(51 78%) after photocoagulation. Macular edema disappeared completely or reduced in 39 eyes(76 42%) after photocoagulation. Conclusion Krypton laser photocoagulation is obviously effective on treatment of branch retinal vein occlusion.
