Detailed Description

The aim of this study is to evaluate the clinical outcome after intraocular injections of Bevacizumab or combination of Bevacizumab and Dexamethasone under pro re nata treatment regimen for the patients with Branch Retinal Vein Occlusion (BRVO) patients. Mean change of logarithm of the minimal angle of resolution (logMAR) visual acuity (VA), central foveal thickness (CFT), contrast sensitivity (CS) as well as predictive factors including best-corrected visual acuity (BCVA), vision related questionnaires and various other ocular parameters will be assessed.
