Review of OCT angiography development

Abstract

Optical coherence tomography (OCT) angiography visualizes capillaries noninvasively. A certain part of the blood flow in the tissue can be depicted by detecting the time change of the OCT signal. Clinical devices equipped with OCT angiography have also appeared, and several clinical researches using OCT angiography have been actively conducted. This review outlines the history of development and characteristics of OCT angiography so far, and the current technical developments are briefly reported.
