Meta-analysis of traditional Chinese medicine and western medicine in treating retinal vein occlusion complicated by macular edema

Objective:TMeta-analysis was performed to evaluate the clinical efficacy of the combination of traditional Chinese medicine and western medicine in treating patients with retinal vein occlusion(RVO)complicated by macular edema(ME).Methods:We searched The CNKI,Wanfang Data,PubMed and Cochrane Library from database.All of randomized controlled trials(RCTs)of the combination of traditional Chinese medicine and western medicine in treating patients with RVO complicated by ME were searched.The Revman5.3 software were used for meta-analysis.Results:A total of 30 trials involving 1943 patients and 1976 eyes were included.Meta-analysis showed that compared with western medicine,the combination of traditional Chinese medicine and western medicine can significantly improve the best corrected visual acuity[(MD=0.08,95%CI=0.07~0.10,P<0.00001)(MD=-0.16,95%CI=-0.24^-0.08,P=0.0002)(MD=5.78,95%CI=1.30~10.25,P=0.01)],reduce the central macular thickness(MD=-54.6,95%CI=-73.76^-35.43,P<0.00001),and improve the clinical effective rate(RR=1.32,95%CI=1.22~1.43,P<0.00001).Conclusion:The combination of traditional Chinese and western medicine in treating patients with RVO complicated by ME was superior to western medicine in improving the best corrected visual acuity,reducing the thickness of macular fovea and improving the clinical efficacy.
