Abstract
Central retinal vein occlusion (CRVO) is the most common vascular disease leading cause of vision loss after diabetic retinopathy (DR) and branch retinal vein occlusion (BRVO). The pathogenesis of CRVO involves a thrombus formation leading to increased retinal capillary pressure, increased vascular permeability, and possibly retinal neovascularization. Vision loss due to CRVO is commonly caused by macular edema. Multiple treatment modalities have been used to treat macular edema. Currently, the most common therapy modality used is intravitreal inhibition of vascular endothelial growth factor (VEGF). The three most widely used agents are aflibercept, bevacizumab, and ranibizumab. In addition, intraocular steroids can be used to treat macular edema. This review will briefly cover the treatment options and discuss in greater detail the efficacy and safety of aflibercept.
