Optical Coherence Tomography Angiography
Investigative Opthalmology & Visual Science, 2016 Optical coherence tomography angiography (OCTA) is a noninvasive approach that can visualize blood vessels down to the capillary level. With the advent of high-speed OCT and efficient algorithms, practical OCTA of ocular circulation is now available to ...

Optical coherence tomography angiography
Progress 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 obtained with older forms of imaging.

Advances in swept-source optical coherence tomography and optical coherence tomography angiography
Advances in Ophthalmology Practice and Research, 2022 The fast development of swept-source optical coherence tomography (SS-OCT) and swept-source optical coherence tomography angiography (SS-OCTA) enables both anterior and posterior imaging of the eye. These techniques have evolved from a research tool to an essential clinical imaging modality.The longer wavelength and faster speed of SS-OCT and SS-OCTA ...

Optical Coherence Tomography Angiography [PDF]
Case Reports in Ophthalmological Medicine, 2018 Optical coherence tomography angiography (OCTA) is a new revolutionary non-invasive imaging modality, built on the platform of optical coherence tomography (OCT). This technique works on the principle of ‘decorrelation’ and is still a nascent technology in its infancy with tremendous potential applicability for diagnosing retinal and choroidal vascular

Optical Coherence Tomography Angiography in Diabetes
Asia-Pacific Journal of Ophthalmology, 2021 The introduction of optical coherence tomography angiography (OCTA) has significantly improved our knowledge on the ocular vascular alterations occurring in diabetes. In this article, we will provide a review of the prominent OCTA findings in diabetes. In details, OCTA demonstrated that both the retinal vessels and the choriocapillaris are affected in ...

Optical Coherence Tomography Angiography [PDF]
Retina, 2015 This issue of the journal RETINA is devoted to the use of optical coherence tomography (OCT) in creation of a new form of angiography, known as OCT angiography. Optical coherence tomography produces depth-resolved evaluation of the reflectance data from tissue.

Optical Coherence Tomography Angiography in Chiasmitis
Case Reports in Ophthalmology, 2022 A 29-year-old girl presented complaining of acute bilateral visual loss associated with mild headache and retrobulbar pain. She was diagnosed with chiasmal optic neuritis caused by multiple sclerosis. Her visual acuity and visual field defect promptly improved after steroid therapy.
