Fluorescein angiography (FA) is a useful examination in patients suffering from diabetic retinopathy (DR). Traditional angiograms explore 30°–50° of the retina at once; however, visualization of peripheral retina is fundamental in order to assess nonperfused areas, vascular leakage, microvascular abnormalities, and neovascularizations. In order to expand the field of view, wide-field and ultra-wide-field imaging has been developed allowing to image up to 200° of retinal surface in one single shot. The aim of this narrative review was to provide an overview of the role of the most recent technique of ultra-wide-field fluorescein angiography in DR.

Abstract
Fluorescein angiography (FA) is a useful examination in patients suffering from diabetic retinopathy (DR). Traditional angiograms explore 30°–50° of the retina at once; however, visualization of peripheral retina is fundamental in order to assess nonperfused areas, vascular leakage, microvascular abnormalities, and neovascularizations. In order to expand the field of view, wide-field and ultra-wide-field imaging has been developed allowing to image up to 200° of retinal surface in one single shot. The aim of this narrative review was to provide an overview of the role of the most recent technique of ultra-wide-field fluorescein angiography in DR.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
