Optical coherence tomography angiography (OCTA) as a new diagnostic tool in uveitis. [PDF]

J Ophthalmic Inflamm Infect, 2019
BACKGROUND The broad spectrum of uveitis disorders requires a multimodal imaging approach in the daily practice of an ophthalmologist. As inflammatory conditions, they have in common an alteration in leukocyte migration. In this context, optical coherence tomography angiography (OCTA) might be of great value for diagnosing or following up patients with

A Framework for the Discovery of Retinal Biomarkers in Optical Coherence Tomography Angiography (OCTA) [PDF]

, 2020
Recent studies have demonstrated the potential of OCTA retinal imaging for the discovery of biomarkers of vascular disease of the eye and other organs. Furthermore, advances in deep learning have made it possible to train algorithms for the automated detection of such biomarkers.

Optical Coherence Tomography Angiography (OCTA) in Multiple Sclerosis and Neuromyelitis Optica Spectrum Disorder. [PDF]

Front Neurol, 2020
Vascular changes are increasingly recognized as important factors in the pathophysiology of neuroinflammatory disease, especially in multiple sclerosis (MS). The relatively novel technology of optical coherence tomography angiography (OCTA) images the retinal and choroidal vasculature non-invasively and in a depth-resolved manner.

Optical coherence tomography angiography (OCTA): A review of the current literature

, 2023
OCTA is an imaging modality used in the assessment of the retinal vasculature. It operates on the principle of coherence tomography used in standard OCT with the addition of delineating the retinal vascular. This provides a modern non-invasive retinal vascular imaging method compared to conventional dye-based imaging.

Optical Coherence Tomography Angiography (OCTA) Analysis of Ischemic vs Non-Ischemic Optic Disc Edema. [PDF]

Neuroophthalmology
This study was designed to compare optical coherence tomography angiography (OCTA) microvasculature characteristics of the optic disc and peripapillary retina in ischemic and non-ischemic optic disc edema and to compare them to normals. We hypothesized that ischemic edema would show significantly decreased vascular density when compared with non ...
