Optical coherence tomography angiography (OCTA) [1] [2] [3] [4] is a non-invasive imaging technique based on optical coherence tomography (OCT) developed to visualize vascular networks in the human retina, [4] [5] [6] [7] [8] [9] choroid, [10] …

OCT angiogram of a normal eye illustrating detailed microvasculature in the macula. The foveal avascular zone is seen in the center of the macula. Optical coherence tomography angiography (OCT-A) has emerged as a non-invasive technique for imaging the microvasculature of the retina and the choroid.

Sep 26, 2024 · Optical coherence tomography (OCT) and optical coherence tomography angiography (OCTA) are non-invasive imaging tests. They use light waves to take cross-section pictures of your retina. With OCT, your ophthalmologist can see each of the retina’s distinctive layers and the optic nerve fiber layer.

Aug 14, 2019 · Optical coherence tomography angiography (OCTA) is a non-invasive imaging technique which can be used to provide three-dimensional visualization of perfused vasculature of the retina and choroid [1, 2].

Apr 15, 2015 · Optical coherence tomography angiography (OCTA) is a new non-invasive imaging technique that employs motion contrast imaging to high-resolution volumetric blood flow information generating angiographic images in a matter of seconds.

OCTA is becoming a staple of retinal clinical practice in the diagnosis and management of AMD, DR and Retinal Vascular Disease

Mar 3, 2020 · Optical coherence tomography angiography (OCTA) is a revolutionary method in the visualization of the vascular system in different retinal and choroidal layers.

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.

Jul 7, 2020 · Optical coherence tomographic angiography (OCTA) can image the retinal blood flow but visualization of the capillary caliber is limited by the low lateral resolution. Adaptive optics (AO) can be used to compensate ocular aberrations when using high numerical aperture (NA), and thus improve image resolution.

Mar 26, 2025 · A groundbreaking study published in 2025 sheds light on how Optical Coherence Tomography Angiography (OCTA) is proving to be a superior tool compared to traditional methods. This research highlights OCTA’s ability to detect subtle vascular changes in highly myopic eyes, which traditional structural imaging fails to identify, offering a new ...
