Optical Coherence Tomography Angiography in Neurology and Neuro-Ophthalmology

Optical coherence tomography angiography (OCT-A) is a recent advancement in retinal imaging that uses high-speed OCT and advanced processing algorithms to generate en face angiographic images of the retinal and choroidal microcirculation, utilizing the non-invasive motion-contrast of intra-luminal erythrocyte flow. This chapter offers a review of the recent translational and clinical applications of OCT-A in the fields of neurology and neuro-ophthalmology, focusing on non-glaucomatous optic neuropathies and other central neurological disorders.
