NCT03297684

Brief Summary

To assess the biomarker profile in diabetic macular edema patients in response to intravitreal aflibercept injection. Patients with diabetic macular edema who meet study requirements will receive monthly intravitreal injections of aflibercept as approved by FDA for a period of 6 months. A small quantity of fluid will be removed from the vitreous at each injection for laboratory evaluation of biomarkers present before, during and after treatment with aflibercept.
