  Purpose

To evaluate, specifically within the Canadian medical environment, the efficacy, safety and cost-efficacy of ranibizumab administered either as combination therapy (ranibizumab plus laser photocoagulation), or as monotherapy in comparison with the current standard of care (laser photocoagulation monotherapy), in patients with visual impairment due to DME.

Primary Outcome Measures:
  • Measure: mean change from baseline in Best Correct Visual Acuity (BCVA) [ Time Frame: 12 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Measure: number of patients with visual acuity above 73 letters [ Time Frame: 3, 6, 9 and 12 months ] [ Designated as safety issue: No ]
  • Measure: number of patients with improvement in BCVA [ Time Frame: 3, 6, 9 and 12 months ] [ Designated as safety issue: No ]
  • Measure: time course of BCVA changes [ Time Frame: 3, 6, 9 and 12 months ] [ Designated as safety issue: No ]
  • Measure: change in central retinal thickness and other anatomical changes [ Time Frame: 3, 6, 9 and 12 months ] [ Designated as safety issue: No ]
  • Measure: 15-letter (3-line) gain in BCVA [ Time Frame: 3, 6, 9 and 12 months ] [ Designated as safety issue: No ]
