Optical coherence tomography angiography

open access: yesProgress in Retinal and Eye Research, 2017
Optical coherence tomography (OCT) was one of the biggest advances in ophthalmic imaging. Building on that platform, OCT angiography (OCTA) provides depth resolved images of blood flow in the retina and choroid with levels of detail far exceeding that ...

Detailed Vascular Anatomy of the Human Retina by Projection-Resolved Optical Coherence Tomography Angiography

open access: yesScientific Reports, 2017
Optical coherence tomography angiography (OCTA) is a noninvasive method of 3D imaging of the retinal and choroidal circulations. However, vascular depth discrimination is limited by superficial vessels projecting flow signal artifact onto deeper layers ...

A deep learning model for identifying diabetic retinopathy using optical coherence tomography angiography

open access: yesScientific Reports, 2021
As the prevalence of diabetes increases, millions of people need to be screened for diabetic retinopathy (DR). Remarkable advances in technology have made it possible to use artificial intelligence to screen DR from retinal images with high accuracy and ...

An overview of optical coherence tomography angiography and the posterior pole

open access: yesTherapeutic Advances in Ophthalmology, 2019
Optical coherence tomography angiography is a relatively new, noninvasive technology that has revolutionized imaging of the retinal and choroidal microvasculature. This technology is based on the detection of movement or changes that represent moving red

Optical coherence tomography angiography analysis of the retina in patients recovered from COVID-19: a case-control study

open access: yesCanadian journal of ophthalmology, 2020
Objective To quantify the density of the macular microvasculature and the area of the foveal avascular zone (FAZ) in patients recovered from Coronavirus Disease 2019 (COVID-19) using optical coherence tomography ...
