Assessing the Efficacy and Safety of Brolucizumab Versus Aflibercept in Patients With Visual Impairment Due to Macular Edema Secondary to Branch Retinal Vein Occlusion

Inclusion Criteria: * Signed informed consent must be obtained prior to participation in the study. * Patients with visual impairment due to ME secondary to BRVO diagnosed \< 6 months prior to screening. * BCVA score between 78 and 23 letters, inclusive, using ETDRS visual acuity testing charts (approximate Snellen equivalent of 20/32 to 20/320) at both screening and baseline visits. Exclusion criteria * Concomitant conditions or ocular disorders in the study eye at screening or baseline which could, in the opinion of the investigator, prevent response to study treatment or may confound interpretation of study results, compromise visual acuity or require medical or surgical intervention during the first 12-month study period (e.g. structural damage of the fovea, vitreous hemorrhage, retinal vascular occlusion other than BRVO, retinal detachment, macular hole, or choroidal neovascularization of any cause, diabetic retinopathy (except mild non-proliferative) and diabetic macular edema). Hemiretinal vein occlusion should be excluded. * Any active intraocular or periocular infection or active intraocular inflammation (e.g. infectious conjunctivitis, keratitis, scleritis, endophthalmitis, infectious blepharitis, uveitis) in study eye at screening or baseline * Uncontrolled glaucoma in the study eye defined as intraocular pressure (IOP) \> 25 mmHg on medication, or according to investigator's judgment, at screening or baseline * Presence of amblyopia, amaurosis or ocular disorde…
