One-year follow-up of ischemic index changes after intravitreal dexamethasone implant for diabetic macular edema: an ultra-widefield fluorescein angiography study

To investigate late changes in peripheral ischemia in patients affected by diabetic macular edema (DME) and treated with repeated dexamethasone (DEX) intravitreal implants over a 1-year period. In this retrospective cohort study, patients older than 18 years of age and with type 2 non-proliferative treatment-naive diabetic retinopathy (DR) and DME at baseline were included.
