Effect of Intravitreal Bevacizumab on Focal Edema With Hard Exudates Secondary to Diabetic Retinopathy

September 22, 2011 updated by: Won Ki Lee, Seoul St. Mary's Hospital

Purpose: To evaluate the efficacy of intravitreal bevacizumab (IVB) on focal edema with hard exudates secondary to diabetic retinopathy.

Design: Prospective interventional case series. Participants: Ten eyes of 10 consecutive patients showing focal edema with hard exudates secondary to diabetic retinopathy which are not eligible for focal laser photocoagulation due to central location (< 500 µm from fovea).
