Comparison of Intravitreal versus Posterior Sub-Tenon's Capsule Injection of Triamcinolone Acetonide for Diffuse Diabetic Macular Edema

The findings from our study neither advocate nor support the use of corticosteroids for the treatment of diabetic macular edema, but do imply that both intravitreal and Sub-Tenon's capsule injections of triamcinolone acetonide may be equally tolerated, with short-term performance clearly favoring the intravitreal (4 mg) more than the SBT capsule (40 mg) route for the anatomic and functional aspects of improvement tested in this investigation.
