氪激光治疗视网膜分支静脉阻塞并发症46例临床分析

Krypton laser photocoagulation treatment of branch retinal vein occlusion with complications

目的:探讨氪激光光凝治疗视网膜分支静脉阻塞并发症的疗效。方法:对46例46眼视网膜分支静脉阻塞出现并发症患者行氪激光治疗。合并黄斑水肿者26例行格栅状光凝,合并新生血管者20例行播散状光凝。3mo后复查眼底荧光血管造影,仍有黄斑渗漏或新生血管未萎缩者行二次激光治疗。结果:黄斑水肿消退,视力提高2行以上者占61%(28/46),不变者为35%(16/46),2例出现视力减退4%(2/46)。新生血管组80%(16/20)患者经1次光凝后新生血管消退,20%(4/20)患者行2次激光治疗后新生血管消退。结论:氪激光光凝治疗视网膜分支静脉阻塞的并发症有效。

AIM： To investigate the effect of krypton laser photocoagulation on branch retinal vein occlusion BRVO） with comptications. METHODS： All of 46 patients 46 eyes with complications of BRVO were photocoagulated by krypton laser ;26 cases with macular edema were performed grid laser photocoagulation;20 cases with neovascularization were performed diffuse laser photo-coagulation. The patients were followed up by fundus examination and fundus fluorescein angiography（FFA）for 3 months. Patients who still had macular edema or neovascularization after the first photocoagulation at the end of 3 months were performed second photocoa-gulation. RESULTS： Macular edema disappeared and visual acuity improved by 2 lines in 28 eyes,visual acuity of 16 cases were the same as before photocoagulation, and 2 cases were decreased. In the 20 patients with neovascularization,neovascularization disappeared in 16 patients after the first photocoagulation, 4 patients after the second photocoagulation disappeared. CONCLUSION： Krypton laser photocoagulation is obviously effective in treatment of BRVO with cimplications.
