Fluorescein angiography (FA) is a useful test in patients affected by diabetic retinopathy (DR) to evaluate the blood-retinal barrier integrity and the presence of non-perfused areas, vascular leakage, microvascular abnormalities, and neovascularization. The peripheral retina is involved in most DR lesions, and, thus, its proper visualization is crucial for the screening, diagnosis, monitoring, treatment, and prognosis of DR. To expand the field of view, wide-field and ultra-wide-field imaging have been developed, allowing images up to 200° of retinal surface in one single photo. In this chapter, emerging issues concerning ultra-wide-field FA in DR are illustrated.

Abstract
Fluorescein angiography (FA) is a useful test in patients affected by diabetic retinopathy (DR) to evaluate the blood-retinal barrier integrity and the presence of non-perfused areas, vascular leakage, microvascular abnormalities, and neovascularization. The peripheral retina is involved in most DR lesions, and, thus, its proper visualization is crucial for the screening, diagnosis, monitoring, treatment, and prognosis of DR. To expand the field of view, wide-field and ultra-wide-field imaging have been developed, allowing images up to 200° of retinal surface in one single photo. In this chapter, emerging issues concerning ultra-wide-field FA in DR are illustrated.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
