Intravitreal Injection of Triamcinolone for Diffuse Diabetic Macular Edema

Abstract

DIABETIC MACULAR edema is one of the main reasons for reduced visual acuity in patients with diabetic retinopathy. According to the results of the study on the early treatment of diabetic retinopathy, diabetic macular edema has usually been treated by focal laser coagulation of leaking circumscribed retinal areas, unless the whole macular region is diffusely affected.¹ In eyes with diffuse macular edema, laser treatment cannot be focused on localized retinal leakage spots since the entire macula is involved. A recommendation for grid laser treatment covering the whole macular region with a fine net of small laser coagulation spots has been controversial, since randomized prospective studies proving the efficacy of this treatment have not yet been published.
