Abstract

PURPOSE: To describe the changes in retinal vascular caliber in response to a single injection of intravitreal triamcinolone (IVTA) in patients with refractory diabetic macular edema. METHODS: Prospective data from a randomized clinical trial were used. The effects of IVTA versus sham injections in patients with refractory diabetic macular edema were evaluated in a randomized clinical trial involving 69 eyes of 43 patients. Of these, 28 eyes (15 IVTA and 13 sham) of 21 patients had gradable retinal photographs at the baseline and 3-month follow-up visit for analysis in the present study. Retinal vascular caliber was measured from digital fundus photographs and summarized as central retinal a..
