Efficacy of Compound Danshen Dripping Pills combined with western medicine in the treatment of diabetic retinopathy: a systematic review and meta-analysis of randomized controlled trials.

Abstract

The Compound Danshen Dripping Pills have been widely used in the treatment of diabetic retinopathy (DR), but there is a lack of systematic review of reports on this topic. To explore the efficacy of Compound Danshen Dripping Pills combined with western medicine in the treatment of diabetic retinopathy, we conducted a meta-analysis. Randomized controlled trials published in the Chinese Medical Literature Database (CBM), Embase, PubMed, and Medline databases from January 2010 to August 2021 were searched. After screening the qualified literature, literature quality was evaluated by the Cochrane Handbook for Systematic Reviews of Interventions. Meta-analysis was performed on outcome measures including effective rate, visual field gray value, hemangioma volume, hemorrhagic plaque area, and visual acuity after diabetic retinopathy treatment with Compound Danshen Dripping Pills using Revman 5.3 analysis software to comprehensively evaluate the utility of Compound Danshen Dripping Pills. A total of 167 documents were preliminarily searched, and 8 studies involving 524 patients were included for meta-analysis. Meta-analysis showed that the statistical value of the effective rate of diabetic retinopathy treatment in the intervention group and control group was OR =5.00, 95% CI: 2.84, 8.83, P<0.0001. The statistical value of visual field gray value comparison was MD =-0.93, 95% CI: -0.98, -0.89, P<0.00001. The statistical value of hemangioma volume was MD =-3.16, 95% CI: -3.48, -2.84, P<0.00001. The statistical value of hemorrhagic plaque area comparison was MD =-0.65, 95% CI: -0.97, -0.32, P<0.0001. The statistical value of visual acuity comparison was MD =0.15, 95% CI: 0.10, 0.19, P<0.00001. The Compound Danshen Dripping Pills combined with western medicine are effective and safe in the treatment of diabetic retinopathy.
