Visible light optical coherence tomography angiography (vis-OCTA) in human retina for small vessel blood oxygenation (Conference Presentation)

Paper Abstract

Although vis-OCT oximetry has been successfully demonstrated in vivo in human retina, it is so far limited on large vessels. To precisely locate the small vessels in depth dimension, OCTA is the natural method since it can effectively enhance the vessel contrast. In this paper, we demonstrate the first visible OCTA image in human retina, the small blood vessel can be located with high fidelity by using both the structural and angiographic contrasts. This technical advance lays a foundation for the absolute sO2 calculation in small vessels in human retina in order to assess local oxygen extraction and metabolism.
