Aktiv komparator: Monthly Ranibizumab
Patients randomized to the Monthly Ranibizumab arm of the study will be administered intravitreal injections each month for their diabetic macular edema for the duration of the study.
|
Pars plana injection of ranibizumab 0.5mg into the vitreous cavity.

Eksperimentel: Treat and Extend Ranibizumab
Patients randomized to this arm of the study will receive intravitreal injections of ranibizumab until their maculae are anatomically "dry," at which point the evaluation and injection interval will be extended.
