Optical coherence tomography angiography [PDF]
Progress in Retinal and Eye Research, 2018 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.

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 ophthalmologists. Clinical investigations that used OCTA have increased exponentially in the past few

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.

Optical Coherence Tomography Angiography in Glaucoma [PDF]
Journal of Glaucoma, 2020 Optical coherence tomography angiography (OCTA) is a relatively new, noninvasive, dye-free imaging modality that provides a qualitative and quantitative assessment of the vasculature in the retina and optic nerve head. OCTA also enables visualization of the choriocapillaris, but only in areas of parapapillary atrophy.

Optical Coherence Tomography Angiography
Sriwijaya Journal of Ophthalmology, 2019 Optical Coherence Tomography Angiography (OCTA) is a new high-resolution imaging method for visualizing retinal and choroidal circulation without any dye injection By detecting intravascular flow quickly when needed and being able to repeat images, as often as needed, without risk to patients, doctors will value OCTA as one of the most important ...

Handheld optical coherence tomography angiography
Biomedical Optics Express, 2017 We developed a handheld optical coherence tomography angiography (OCTA) system using a 100-kHz swept-source laser. The handheld probe weighs 0.4 kg and measures 20.6 × 12.8 × 4.6 cm3. The system has dedicated features for handheld operation. The probe is equipped with a mini iris camera for easy alignment. Real-time display of the en face OCT and cross-
