Real-time eye motion correction in phase-resolved OCT angiography with tracking SLO [PDF]
, 2013 In phase-resolved OCT angiography blood flow is detected from phase changes in between A-scans that are obtained from the same location. In ophthalmology, this technique is vulnerable to eye motion. We address this problem by combining inter-B-scan phase-

Wide-Field OCT Angiography at 400 KHz Utilizing Spectral Splitting
Photonics, 2014 Optical angiography systems based on optical coherence tomography (OCT) require dense sampling in order to maintain good vascular contrast. We demonstrate a way to gain acquisition speed and spatial sampling by using spectral splitting with a swept ...

Optical Coherence Tomography-Angiography of a large retinal microaneurysm
American Journal of Ophthalmology Case Reports, 2020 A 63-year-old healthy woman was referred for a retinal examination. Dilated fundus examination of the left eye revealed small retinal hemorrhage with surrounding exudation, most consistent with a large retinal microaneurysm, which was confirmed by ...
