Eligibility Criteria:
Inclusion Criteria:
* Diagnosis of macular edema due to central retinal vein occlusion foveal thickness \> 250 μm (measured by OCT)
* Age \> 18 years
* Written informed consent of the patient
* BCVA score in the study eye between 24 letters (20/320) and 78 letters (20/25) measured in ETDRS chart
* History of CRVO no longer than 6 months
* Presence of capillary non-perfusion in peripheral retina larger than 5 disc areas documented in ultra wide-field fluorescein angiography
* Ability and willingness to attend all scheduled visits and assessments
Exclusion Criteria:
* CRVO with ischemic maculopathy defined as diameter of the foveolar avascular zone larger than 2 optic disc diameters
* Macular edema due to another etiology than retinal vein occlusion (e.g. diabetic maculopathy, uveitis, age related macular degeneration, Irvine-Gass syndrome)
* History of idiopathic central serous chorioretinopathy
* Presence of vitreoretinal interface disease (e.g. vitreomacular traction, epiretinal membrane), either on clinical examination or in OCT
* An eye that, in the investigator's opinion, would not benefit from resolution of macular edema, such as eyes with foveal atrophy, dense pigmentary changes, or dense subfoveal hard exudates
* Aphakia in the study eye
* Scatter laser photocoagulation or macular photocoagulation in the study eye prior to study entry
* Intraocular or periocular injection of steroids in the study eye prior to study entry
* Previous use of an anti-VEGF drug in the study eye
* Cataract surgery or any other intraocular surgery in the study eye within 3 months prior to study entry
* Uncontrolled glaucoma (defined as intraocular pressure ≥ 30 mm Hg despite treatment with maximal anti-glaucoma medications)
* History of stroke, myocardial infarction, transient ischemic attacks within 3 months prior to the study
* Pregnancy (positive urine pregnancy test) or lactation
* The presence of active malignancy, including lymphoproliferative disorders.
* History of allergy to fluorescein or any component of the ranibizumab formulation
* Active intraocular infection
* Participation in another simultaneous interventional medical investigation or trial
* Women with child bearing potency without effective contraception (i. e. implants, injectables, combined oral contraceptives, some IUDs or vasectomised partner) during the conduct of the trial.
