Abstract Purpose: To summarize the evidence from Cochrane systematic reviews on interventions for Central or Branch Vein Occlusion. Methods: We included and summarized the results from Cochrane systematic reviews on interventions for both types of occlusion. The initial search retrieved was 21 reviews and four of them were selected. Results: The four systematic reviews included evaluated the effects of laser techniques and intravitreal injections of Anti-Vascular Endothelial Growth Factor (anti-VEGF) and corticosteroids on Branch and Central Retinal Vein Occlusions. Conclusions: In Branch Retinal Vein Occlusion was found some benefits in the use of grid laser when comparable to no intervention but insufficient evidence about the use of early grid laser, subthreshold laser, intravitreal triamcinolone or anti-VEGF over macular grid laser photocoagulation. In Central Retinal Vein Occlusion with Macular Edema was found insufficient evidence to determine the benefits of intravítreo steroids but ranibizumab may improve clinical and visual outcomes at six and 12 months and repeated intravitreal injection of anti-VEGF agents improved visual outcomes at six months when compared to no treatment.
