RESUMO
@#AIM:To evaluate the long-term efficacy and safety of retinal photocoagulation combined with intravitreal injection of Ranibizumab(IVR)and simple Ranibizumab in the treatment of branch retinal vein occlusion secondary macular edema(BRVO-ME).<p>METHODS: The literatures related to randomized controlled clinical studies on the treatment of BRVO-ME with laser and Ranibizumab in Embase, The Cochrane Library, PubMed, China National Knowledge Infrastructure(CNKI), Wanfang Database and China Science and Technology Journal Database(VIP)were systematically retrieved, and the risk assessment was carried out and data indicators were extracted for the included studies. RevMan 5.3 software was used for data analysis and funnel plot was used to evaluate publication bias.<p>RESULTS: Totally 7 studies were included, with 641 eyes. There was no significant difference in the best corrected visual acuity(BCVA)between the laser combined with Ranibizumab group and the simple Ranibizumab group at 12mo \ and 24mo \ after treatment. There was no significant difference in central foveal thickness between the two groups at 12mo \ and 24mo \. There were no statistically significant differences in the injection times of Ranibizumab and the incidence of final adverse events between the two groups at 12mo and 24mo after treatment.<p>CONCLUSION: Compared with the treatment of BRVO-ME with simple Ranibizumab, there was no significant difference in the long-term efficacy of vision and central foveal thickness for the laser combined with Ranibizumab, and there was no significant difference in the injection times and safety of Ranibizumab.
