About this trial
This is an interventional treatment trial for Diabetes Complications focused on measuring clinically significant macular edema, diabetic macular edema, focal edema, focal laser photocoagulation, hard exudates, intravitreal bevacizumab
Eligibility Criteria
Inclusion Criteria:
- patients of either gender aged > 18 years
- patients with type 2 diabetes
- central macular thickness > 300 µm on OCT
- eyes not eligible for focal laser photocoagulation due to the central location of hard exudates (< 500 µm)
- an area of retinal thickening less than 2 disc areas in diameter
- 67% or more of leakage associated with microaneurysms
Exclusion Criteria:
- eyes with history of laser photocoagulation or pharmacological intervention for DME on study eye
- eyes with any pharmacologic intervention on fellow eye within 6 months
- history of ocular diseases other than diabetic retinopathy
- surgical history other than cataract extraction with intraocular lens implantation
- panretinal photocoagulation within 3 months of enrollment
- media opacity
- any thromboembolic event within 6 months, or evidence of active cardiac ischemia on electrocardiogram (ECG) at time of screening.

Brief Summary
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).
