Optical coherence tomography angiography in the diagnosis of ophthalmologic diseases: problems and prospects (Review)

Abstract

Optical coherence tomography angiography, which is based on optical coherence tomography, is a diagnostic technology that makes it possible to noninvasively visualize in vivo the dynamics of blood flow with micrometer resolution in depth down to several millimeters. This analytic review presents the construction principles and prospects of using optical coherence tomography angiography in ophthalmology. Problems of the anatomical and functional diagnosis of the retina in real time are analyzed by comparing the architecture of modern optical coherence tomography and optical coherence tomography angiography. The results of applying optical coherence tomography angiography in the study of the pathogenesis and antiangiogenic therapy of age-related macular dystrophy are discussed.
