BACKGROUND AND OBJECTIVE: To evaluate the efficacy of combined bevacizumab-triamcinolone intravitreal injection in the treatment of diabetic macular edema (DME) compared to monotherapy. PATIENTS AND METHODS: At eight clinical sites, 111 patients with DME were randomly assigned to receive an intravitreal injection of bevacizumab (Avastin; Genentech, South San Francisco, CA), triamcinolone (Ophthalmos Pharmaceutical Industry, São Paulo-SP, Brazil), or their combination. The primary outcome was visual acuity (VA) at 6 months' follow-up. RESULTS: The average number of injections was 3.2 in the bevacizumab group, 2.4 in the combined group, and 2.1 in the triamcinolone group. All groups presented with improvements in VA (P < .001); however, no differences between groups were observed (P = .436). Mean reduction in central retinal thickness was statistically different only between the triamcinolone and bevacizumab groups (P < .015). CONCLUSION:Mono- or combination therapy was effective for DME treatment. No synergistic effects were observed; however, triamcinolone alone or a drug combination may reduce the number of injections required when compared to bevacizumab alone.
