Mobility and transverse flow visualization using phase variance contrast with spectral domain optical coherence tomography [PDF]
, 2007 Phase variance-based motion contrast is demonstrated using two phase analysis methods in a spectral domain optical coherence tomography system. Mobility contrast is demonstrated for an intensity matched Intralipid solution placed without flow within ...

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 ...

Paracentral acute middle maculopathy following coronary angiography
American Journal of Ophthalmology Case Reports, 2022 Purpose: To describe a case of paracentral acute middle maculopathy (PAMM) after coronary angiography. Observations: A 65-year-old female patient exhibited a dense central scotoma 5 hrs after coronary angiography. She presented the next day to the retina

Glaucomatous vertical vessel density asymmetry of the temporal raphe detected with optical coherence tomography angiography. [PDF]
, 2020 Changes in retinal vasculature and ocular circulation may play an important role in the glaucoma development and progression. We evaluated the vertical asymmetry across the temporal raphe of the deep retinal layer vessel density, using swept-source ...
