Clinical Study of Sulfotanshinone Sodium Injection in Treating Non-Ischemic Retinal Vein Occlusion

Objectives: To study the effect of sulfotanshinone sodium (SS) injection in the treatment of nonischemic retinal vein occlusion (RVO). Methods: Sixty-two RVO patients treated in our hospital between Jan. 2013 and Oct. 2014 were randomly divided into Control Group (30 patients; Bendazol tablets) and Treatment Group (32 patients, Bendazol tablets + SS injections), each with a follow-up period of 6 months. Statistical analysis was then performed on changes in visual acuity, central retinal thickness (CRT) and retinal circulation time (RCT) before and after the treatment. Results: After treatment, both Control Group and Treatment Group witnessed an improvement on visual acuity (Control Group: t = 2.103, p = 0.044; Treatment Group: t = 8.021, p = 0.000). Visual acuity could be greatly improved in Treatment Group when compared with Control Group, with significant differences (p < 0.01). Macular edema could be greatly relieved in Treatment Group measured by CRT (t = 2.571, p = 0.007) while the difference was of no statistical significance in Control Group (t = 1.016, p = 0.070). RCT were remarkably shortened in both groups (Control Group: t = 43.83, p = 0.000; Treatment Group: t = 27.34, p = 0.000), and when compared with Control group, the changes in Treatment Group were more significant (p < 0.05). Conclusion: SS injection could effectively improve the therapeutic effect in patients with non-ischemic retinal vein occlusion.
