Abstract

Optical coherence tomography angiography (OCT-A) is an advanced noninvasive retinal blood flow imaging technique. It uses motion-contrast imaging to obtain high-resolution volumetric blood flow information to enhance the study of retinal and choroidal vascular pathologies. OCT-A can obtain detailed images of the radial peripapillary network, the deep capillary plexus (DCP), the superficial capillary plexus (SCP) and the choriocapillaris. In addition, compared to fluorescein angiography (FA), this technique does not require the use of injected dye. This chapter aims to present OCT-A technology and clarify its terminology and limitations. The discussion summarizes the potential application of the technology in different retinal and choroidal diseases.

Keywords: Optical coherence tomography angiography, Principles, Clinical relevance, Retinal diseases, Choroidal diseases.
