Brief Summary

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

This study is to see whether treating diabetic retinal swelling with ranibizumab injections into the eye monthly is better than treating diabetic retinal swelling with ranibizumab injections into the eye less frequently.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a prospective randomized study comparing two groups of patients with diabetic macular edema. One group will receive injections of ranibizumab monthly and the other group will have the option to receive injections of ranibizumab less frequently. That is eligible to receive the injections less frequently will have fewer injections given if the patients in that group are doing well.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

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.

Group Type ACTIVE_COMPARATOR

Ranibizumab

Intervention Type DRUG

Pars plana injection of ranibizumab 0.5mg into the vitreous cavity.

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.

Group Type EXPERIMENTAL

Ranibizumab

Intervention Type DRUG

Pars plana injection of ranibizumab 0.5mg into the vitreous cavity.
