Optical coherence tomography angiography: Technical principles and clinical applications in ophthalmology
Abstract
Optical coherence tomography angiography (OCTA) is a functional extension of OCT that provides information on retinal and choroidal circulations without the need for dye injections. With the recent development of high-speed OCT systems and efficient algorithms, OCTA has become clinically feasible. In this review article, we discuss the technical principles of OCTA, including image processing and artifacts, and its clinical applications in ophthalmology. We summarize recent studies which qualitatively or quantitatively assess disease presentation, progression, and/or response to treatment.
Keywords: Choroidal neovascularization; diabetic retinopathy; glaucoma; optic disc; optical coherence tomography angiography; retina.
