方法：将64例视网膜静脉阻塞患者随机分为激光治疗组(对照组，32例)和激光联合复方血栓通胶囊治疗组(观察组，32例)，观察对比两组治疗后的视力、视网膜黄斑厚度和有效率。

结果：观察组临床总有效率和视力进步比例均显著高于对照组，两组间差异具有统计学意义(P<0.05或P<0.01)； 两组治疗后1、3、6mo的黄斑中心凹厚度均较治疗前显著降低(P<0.05)，但观察组治疗后1、3、6mo的黄斑中心凹厚度均明显小于对照组同期(P<0.05)。

结论：激光联合复方血栓通胶囊治疗视网膜静脉阻塞伴黄斑水肿有较好的疗效，能有效提高视力，降低视网膜黄斑厚度，值得进一步研究。

METHODS: Sixty-four patients with retinal vein occlusion were randomly divided into laser photocoagulation treatment group(control group, n=32)and laser photocoagulation combined with compound xueshuantong capsule treatment group(observation group, n=32). The visual acuity, macular thickness and clinical effective rate of the two groups were observed and compared.

RESULTS:The total clinical effective rate and the proportion of visual improvement of the observation group were significantly higher than those of the control group, and the differences between the two groups were statistically significant(P<0.05 or P<0.01); The macular thickness at 1, 3, 6mo after the treatment of the two groups were significantly lower than those before the treatment(P<0.05), and macular thickness at 1, 3, 6mo after the treatment of the observation group were significantly lower than those of the control group at the same period(P<0.05).

CONCLUSION:Laser photocoagulation combined with compound xueshuantong capsule has a good effect in treating retinal vein occlusion, which can effectively improve visual acuity, reduce macular thickness, and deserves further study.
