Optical Coherence Tomography Angiography of the Optic Disc; an Overview

Handan Akil et al. J Ophthalmic Vis Res. 2017 Jan-Mar.

Abstract

Different diseases of the optic disc may be caused by or lead to abnormal vasculature at the optic nerve head. Optical coherence tomography angiography (OCTA) is a novel technology that provides high resolution mapping of the retinal and optic disc vessels. Recent studies have shown the ability of OCTA to visualize vascular abnormalities in different optic neuropathies. In addition, quantified OCTA measurements were found promising for differentiating optic neuropathies from healthy eyes.

Keywords: Glaucoma; Optic Disc; Optic Nerve Head; Optic Neuropathy; Optical Coherence Tomography Angiography.
