Optical coherence tomography angiography (OCT-A) has emerged as a non-invasive technique for imaging the microvasculature of the retina and the choroid. The first clinical studies using this innovative technology were published in 2014 .

2024年9月26日 · 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.

2017年3月15日 · OCT-A imaging is based on the principle of motion contrast portraying differing patterns of reflectance across time due to red blood cell movement within tissue. 1,2. Fig. 4. Foveal enlargement and perifoveal capillary remodeling detected with OCT-A in a diabetic eye without funduscopically visible diabetic retinopathy.

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] …

2015年4月15日 · 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.

2018年9月15日 · Optical coherence tomography angiography (OCT-A) is a relatively new, noninvasive imaging technique that obtains images in rapid succession and evaluates for changes to examine retinal and choroidal blood flow.

Optical Coherence Tomography Angiography (OCT-A) is a non-invasive imaging modality that allows a detailed and three-dimensional study of retinal and choroidal vessels. This article discusses the anatomy of normal retinal vasculature and its analysis by OCT-A.

OCT angiography (OCTA) has several advantages over traditional imaging techniques, including being noninvasive, depth resolved, and rapid. OCTA can distinguish the various vascular networks without obscuration by leakage, making it helpful for characterizing neovascularization and nonperfusion.

2021年6月30日 · Optical coherence tomography angiography (OCT-A) is a novel technology that provides a dyeless, three-dimensional view of chorioretinal microvasculature. OCT-A adds a layer of dynamic and functional vascular data onto the structural anatomical information recognizable in conventional OCT imaging.

Optical coherence tomography angiography (OCTA) can image the retinal vasculature in vivo, without the need for contrast dye. This technology has been commercially available since 2014, however, much of its use has been limited to the research ...
