Optical Coherence Tomography Angiography as an Imaging Modality for Evaluation of Diabetic Macular Edema

Diabetic retinopathy remains a leading cause of blindness worldwide in patients aged 20–64 years.[1] Diabetic macular edema (DME) threating or involving the fovea is a common etiology for vision loss. Traditionally, treatment methods have been guided by contact and non‑contact slit lamp biomicroscopy, fluorescein angiography and fundus stereo photography.[1] Fluorescein angiography (FA) is a dynamic, invasive imaging technique first described in 1961 and more thoroughly invested and popularized by Gass in 1967.
