Recent advances in the use of optical coherence tomography in neuro‐ophthalmology: A review

Abstract

AbstractOptical coherence tomography (OCT) is an in vivo imaging modality that provides non‐invasive, high resolution and fast cross‐sectional images of the optic nerve head, retina and choroid. OCT angiography (OCTA) is an emerging tool. It is a non‐invasive, dye‐free imaging approach of visualising the microvasculature of the retina and choroid by employing motion contrast imaging for blood flow detection and is gradually receiving attention for its potential roles in various neuro‐ophthalmic and retinal conditions. We will review the clinical utility of the OCT in the management of various common neuro‐ophthalmic and neurological disorders. We also review some of the OCTA research findings in these conditions. Finally, we will discuss the limitations of OCT as well as introduce other emerging technologies.
