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 neovas-cularization,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.·
