Efficacy and safety of intravitreal therapy in macular edema due to branch and central retinal vein occlusion: a systematic review.

Intravitreal agents have replaced observation in macular edema in central (CRVO) and grid laser photocoagulation in branch retinal vein occlusion (BRVO). We conducted a systematic review to evaluate efficacy and safety outcomes of intravitreal therapies for macular edema in CRVO and BRVO.
