A review of optical coherence tomography angiography (OCTA) [PDF]

open access: yesInternational Journal of Retina and Vitreous, 2015
Optical coherence tomography angiography (OCTA) is a new, non-invasive imaging technique that generates volumetric angiography images in a matter of seconds. This is a nascent technology with a potential wide applicability for retinal vascular disease. At present, level 1 evidence of the technology's clinical applications doesn't exist.

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

open access: yesFront 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 in diabetic retinopathy. [PDF]

open access: yes, 2023
There remain many unanswered questions on how to assess and treat the pathology and complications that arise from diabetic retinopathy (DR). Optical coherence tomography angiography (OCTA) is a novel and non-invasive three-dimensional imaging method that

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

open access: yes, 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): A review of the current literature

open access: yes, 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.
