Brief Summary
Purpose: To compare the effects of macular photocoagulation with or without intravitreal bevacizumab (IVB) or triamcinolone (IVTA) for the treatment of diabetic macular edema (DME). Casuistic and Methods: 58 eyes of 44 patients with diffuse DME were randomized to receive either IVB + focal/grid laser (IVB-Laser, n=19), IVTA + focal/grid laser (IVTA-Laser, n=16) or focal/grid laser alone (Laser, n=23). Ophthalmic evaluation, including best-corrected visual acuity (BCVA), intraocular pressure (IOP) and central macular thickness (CMT) were performed at baseline and monthly for 12 months.

Eligibility Criteria
You may qualify if:
- clinically significant diabetic macular edema (DME) with diffuse leakage involving the center of the fovea, with DME greater than 275 microns in OCT examination
- BCVA between 0.3 LogMAR (logarithm of smaller angle of visual resolution) (20/40) and 1.6 LogMAR (20/800)
- signed of inform Consent.
You may not qualify if:
- HbA1c levels greater than 10%
- thromboembolic event history (including myocardial infarction and stroke)
- vitreo-macular traction on OCT
- coagulation disorders
- macular ischemia on fluorescein angiography examination
- proliferative diabetic retinopathy that required treatment
- eye surgery
- history of ocular hypertension or glaucoma
- any ocular pathology which in the opinion of the investigator, could macular edema or change the visual acuity during the study period (for example, retinal vascular occlusion, uveitis or other inflammatory eye disease, neovascular glaucoma)
- systemic corticosteroid therapy
- any conditions that could affect the documentation
- any previous treatment for diabetic macular edema.
