Summary:

      This was a Phase III, multicenter, randomized, double-masked, sham injection-controlled study
      of the efficacy and safety of intravitreal ranibizumab compared with sham injections in
      patients with macular edema secondary to central retinal vein occlusion (CRVO); 392 patients
      with CRVO were enrolled at 95 investigational sites in the United States. The study included
      a treatment period (6 months) and an observation period (6 months).

             in the study (e.g., chronic alcoholism or drug abuse, personality disorder or use of
             major tranquilizers, indicated difficulty in long-term follow-up, and likelihood of
             survival of less than 1 year)

          -  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

          -  Presence of an ocular condition that, in the opinion of the investigator, might affect
             macular edema or alter visual acuity during the study (e.g., uveitis or other ocular
             inflammatory disease, neovascular glaucoma, Irvine-Gass syndrome, or prior macula-off
             rhegmatogenous retinal detachment)

             to reduced visual acuity

          -  Presence of a substantial cataract that, in the opinion of the investigator, is likely
             to be decreasing visual acuity by 3 lines or more (i.e., a 20/40 cataract)
