The Effect of Intravitreal Injection of Anti-VEGF on Macular Edema and Visual Acuity, after Central Retinal Vein Occlusion

Central retinal vein occlusion (CRVO) is a common retinal vascular disorder which affect the patient visual ability. Visual prognosis depends on the type of retinal vein occlusion, that can be ischemic or non-ichemic, its severity, degree of retinal ischemia or macular edema and development of complications. The two most frequent complications of CRVO are persistent macular edema and neovascularization. One of the best and effective treatment for macular edema and neovascularisation seems to be intra vitreal anti-VEGF. Case report: We report 3 cases of CRVO with macular edema, treated with 3 intavitreal aflibercept (EYLEA) in 3 months. The Visual acuity (VA) improved on all 3 cases after each injection. This article aims to review the effect of anti-VEGF drugs in macular edema and improving vision in patients with CRVO.Keywords: CRVO, macular edema, coroidal neovascularisation, visual acuity, anti-VEGF treatment.
