Eligibility
Inclusion criteria
Inclusion criteria: Macular edema persisting for more than 3 months period despite conventional medication listed above. Central retinal vein occlusion is confirmed by slit-lamp biomicroscopy and fluorescein angiography (FLAG). Patients randomized into ranibizumab-treated group do not receive macular laser treatment. Macular edema is defined by OCT: the thickness of central foveal area calculated by macular map analysis is above 280 µm and/or retinal thickness is above 330 µm at any region of the macula calculated by retinal thickness analysis. Baseline visual acuity is less than 78 ETDRS letters (or 20/32 Snellen equivalent). 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

| Measure | Time frame |
|---|---|
| Main Objective: Primary objectives: To assess the superiority of intravitreal (IVT) ranibizumab to conventional treatment concerning prevention of visual loss or improvement of BCVA as determined by the mean change of BCVA tested by ETDRS chart compared to baseline in 12 months period, when intravitreal ranibizumab is applied monthly in the first 3 months period, and later when visual acuity (VA) decreases with more than 5 letters at any visit performed monthly. ;Secondary Objective: Secondary objectives: The efficacy of treatment concerning change of anatomical structure of macular region detected by Optical Coherence Tomography (OCT) – the mean change of macular thickness (micron) at each months of 1 year period. ;Primary end point(s): Mean change of BCVA tested by ETDRS chart compared to baseline in 12 months period. | — |
