Inclusion criteria: • Signed informed consent • CRVO or BRVO • No requirement for panretinal laser coagulation • No active proliferative disease (NVD/NVE/rubeosis) • Patients with BRVO will only included if vision is better than 0.4 or if previous focal laser coagulation has shown no significant improvement in vision. • Retinal thickness of at least 250µm due to intraretinal or subretinal edema as measured by OCT. Are the trial subjects under 18? no Number of subjects for this age range: F.1.2 Adults (18-64 years) yes F.1.2.1 Number of subjects for this age range F.1.3 Elderly (>=65 years) yes F.1.3.1 Number of subjects for this age range
Exclusion criteria
Exclusion criteria: Prior/Concomitant Treatment • Previous vitrectomy • Laser coagulation within the last 3 month • Previous participation in any studies of investigational drugs within 3 month preceding Day 0 including intravitreal Triamcinolone Concurrent Ocular Conditions • Any concurrent intraocular condition in the study eye (e.g., cataract or diabetic retinopathy) that, in the opinion of the investigator, could either Require medical or surgical intervention during the 12-month study period to prevent or treat visual loss that might result from that condition, or If allowed to progress untreated, could likely contribute to loss of at least 2 Snellen equivalent lines of best corrected visual acuity over the 12-month study period • Active intraocular inflammation (grade trace or above) in the study eye • Current vitreous hemorrhage in the study eye • History of idiopathic or autoimmune-associated uveitis in either eye • Infectious conjunctivitis, keratitis, scleritis, or endophthalmitis in either eye • Intraocular surgery (including cataract surgery) in the study eye within 2 months preceding Day 0 • Uncontrolled glaucoma in the study eye (defined as intraocular pressure ?30 mmHg despite treatment with anti-glaucoma medication) • History of vitrectomy or complicated cataract surgery with rupture of the posterior lens capsule Concurrent Systemic Conditions • Any planned ocular surgery within the study period. • Patients on anticoagulation therapy other than Aspirin. • Premenopausal women not using adequate contraception The following are considered effective means of contraception: surgical sterilization; use of oral contraceptives; barrier contraception with either a condom or diaphragm in conjunction with spermicidal gel; an IUD; or contraceptive hormone implant or patch. • History of other disease, metabolic dysfunction, physical examination finding, or clinical laboratory finding giving reasonable suspicion of a disease or condition that contraindicates the use an investigational drug or that might affect interpretation of the results of the study or render the subject at high risk for treatment complications • Current treatment for active systemic infection Other • History of allergy to fluorescein, not amenable to treatment • Inability to obtain fundus photographs or fluorescein angiograms of sufficient quality to be analyzed and graded by the investigators • Inability to comply with study or follow up procedures
