AIM:To observe the effects of compound Xueshuantong on fundus morphology of patients with vein occlusion in retinal branches.

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.
