Sustained Benefits from Ranibizumab for Central Retinal Vein Occlusion with Macular Edema: 24-Month Results of the CRYSTAL Study

An individualized, stabilization criteria-driven dosing regimen of ranibizumab 0.5 mg led to sustained BCVA gains for up to 24 months in patients with CRVO. The presence of macular ischemia at baseline did not influence VA gains. Shorter duration of CRVO at baseline was associated with better VA gains. Safety findings were consistent with those reported in previous ranibizumab studies in patients with CRVO.
