方法：经眼底荧光血管造影(FFA)确诊为视网膜分支静脉阻塞(BRVO)患者60例60眼。患者随机分两组：A组(治疗组)使用氩绿视网膜光凝治疗30例； B例(对照组)口服活血化瘀药物(复方血栓通胶囊)治疗30例； 两组患者随访时间为治疗后1，3，6，12mo，随访内容为视力、FFA检查及眼底情况，对治疗6mo后视力恢复结果和黄斑水肿消退情况进行对比。

结果：A组：显效8例，有效20例，无效2例。B组：显效2例，有效14例，无效14例。A组合并黄斑囊样水肿者14例，给予氩绿视网膜光凝治疗后黄斑水肿消退12例，未消退2例； B组合并黄斑囊样水肿者13例，药物治疗后黄斑水肿消退3例，未消退10例，经卡方检验，差异有统计学意义(P<0.05)。

结论：氩绿激光对视网膜分支静脉阻塞的激光治疗有显著疗效，激光治疗组治疗后6mo病情稳定，效果好。

METHODS:The 60 BRVO patients clinically confirmed by fundus fluorescein angiography(FFA)were randomly divided into 2 groups: group A(treatment group)30 cases underwent argon chlorine laser photocoagulation; group B(control group)30 cases were for activating blood circulation and eliminating stasis drugs(compound thrombosis the capsule)). The results of visual acuity and macula edema regression in the two groups 6 months after treatment were compared.

RESULTS: Group A: obviously effective in 8 cases, effective 20 cases. Group B: obviously effective in 2 cases, effective in 14 cases, invalid in 14 cases; Group A had 14 cases combined with macular edema, and after argon chlorine retinal photocoagulation, macular edema disappeared in 12 cases, not retreat in 2 cases; Group B had 13 cases combined with macular edema, and macular edema disappeared after medical treatment in 3 cases, not disappeared in 10 cases.

CONCLUSION:The argon laser photocoagulation is an effective treatment for BRVO, promote the visual acuity, shorten the duration of symptoms.
