Comparative Therapy Evaluation of Intravitreal Bevacizumab and Triamcinolone Acetonide on Persistent Diffuse Diabetic Macular Edema

With the generally used concentration, intravitreal injection of triamcinolone acetonide showed better results in reducing DME and in the improvement of VA than that of bevacizumab, suggesting that the pathogenesis of DME is not only attributable to VEGF-dependency, but is also attributable to other mechanisms suppressed by corticosteroid.
