方法：选取视网膜分支静脉阻塞患者85例85眼随机分为两组，实验组患者43例接受复方血栓通胶囊治疗，对照组患者42例接受丹参治疗，对于两组患者治疗前后的眼底形态学改变进行对照研究。

结果：实验组患者的黄斑水肿消退率及治疗有效率显著高于对照组。两组患者治疗前的最佳矫正视力、视网膜静脉相对直径和视网膜出血相对面积均无显著差异，治疗后两组患者的最佳矫正视力均显著升高，但实验组好于对照组； 两组患者治疗后的视网膜静脉相对直径和视网膜出血相对面积均较治疗前显著降低或缩小，实验组治疗后的视网膜出血相对面积显著小于对照组。

结论：复方血栓通胶囊可以有效促进视网膜分支静脉阻塞患者的视力恢复和视网膜出血面积缩小，效果优于丹参治疗。

METHODS: Eight-five patients(85 eyes)with vein occlusion in retinal branches were selected and divided into two groups. Forty-three patients in experimental group were treated with compound Xueshuantong capsules, while 42 cases in control group with salvia miltiorrhiza. The preoperative and postoperative fundus morphological variations of patients in two groups were compared.

RESULTS: The extinction rate of macular edema and effective rate of patients in experimental group were significantly higher than those in control group. Compared with the optimal corrected vision, relative diameter of retinal veins and square of retinal hemorrhage before treatment, there was no significant difference. However, after treatment, the optimal corrected vision of patients in two groups elevated remarkably, and the optimal vision in experimental group was notably higher than that in control group; the relative diameter of retinal veins and relative square of retinal hemorrhage of patients after treatment significantly decreased or lessened in two groups, and relative square of retinal hemorrhage of patients in experimental group was distinctly smaller than that in control group.

CONCLUSION: Compound Xueshuantong capsule can effectively promote the vision recovery of patients with vein occlusion in retinal branches, and lessen the square of retinal hemorrhage, with the therapeutic effect superior to salvia miltiorrhiza.
