This clinical trial is designed to compare ranibizumab in comparison with Dexamethasone implant after 6 months of treatment. In the study arm Ranibizumab will be given monthly in a pro re nata scheme whereas the comparator Dexamethasone implant is given once at Month 0 with sham injections PRN afterwards.

Primary Outcome Measures:
  • Measure : mean average BCVA change from Month 1 through Month 6 to Baseline [ Time Frame: 6 month ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Measure : mean BCVA change at Month 6 [ Time Frame: 6 month ] [ Designated as safety issue: No ]
  • Measure: percentage of patients gaining / losing ≥ 15 / 10 / 5 letters [ Time Frame: 6 month ] [ Designated as safety issue: No ]
  • Measure: time to achieve a significant improvement ≥ 15 letters [ Time Frame: 6 month ] [ Designated as safety issue: No ]
  • Measure: change over time of the central retinal thickness [ Time Frame: 6 month ] [ Designated as safety issue: No ]

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Patients diagnosed with visual impairment due to macular edema following BRVO
  • Diagnosis of BRVO at maximum 6 months prior to Screening
  • BCVA using ETDRS charts of 20/40 to 20/400 in the study eye

Exclusion Criteria:

  • Anti-VEGF-treatment in the study or the fellow eye 3 months prior to Baseline
  • IOP ≥ 30mmHg or uncontrolled glaucoma; patients may be re-screened after 1 month if they have undergone glaucoma treatment
  • Improvement of > 10 letters on BCVA between Screening and Baseline

Other protocol-defined inclusion/exclusion criteria may apply
