Optical coherence tomography (OCT) angiography is a non-invasive method of visualizing the microvasculature in

the eye. It contrasts flowing blood from static tissues by assessing the change in the OCT signal over time. With

the continued development of high-speed OCT and improved algorithms, practical OCT angiography is now

available clinically. OCT angiography is particularly well suited for investigations relating to neovascularization

and capillary dropout. Recent clinical work has shown that OCT angiography can be used to track changes in

choroidal neovascularization in response to treatment and, in conjunction with other imaging modalities, aid

in the study of the pathophysiology of retinal degeneration.
