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