Predictive Factors for the Progression of Diabetic Macular Ischemia – Corrected Proof
Purpose: To investigate the predictive factors for diabetic macular ischemia progression through the analysis of fluorescein angiography (FA) parameters.Design: Retrospective, longitudinal study.Methods: Data were collected from 79 eyes of 79 patients with type 2 diabetes mellitus. Macular ischemia severity was assessed using Early Treatment Diabetic Retinopathy Study (ETDRS) protocols and custom software used to quantify the foveal avascular zone (FAZ) area. Patients with ischemia grades “mild,” “moderate,” or “severe” and at least 2 macula-centered FA images over a minimum of 6 months were included. Main outcome measures were change in macular ischemia grades and FAZ enlargement rate (mm2/year).Results: The median FAZ (Read more...)
