Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.
