    OCT Angiography Face Mask-associated Artifacts During the COVID-19 Pandemic

    Prcis: Face mask wearing has no significant effects on artifacts or vessel density measurements in optic nerve head and macular OCT-Angiography scans. Purpose: To assess the difference in area of artifacts observed in optical coherence tomography angiography (OCT-A) scans with and without face mask wear and to verify if mask wear interferes with OCT-A vessel density measurements. Subjects and controls: 64 eyes of 10 healthy subjects, 4 ocular hypertensive, 8 glaucoma suspects, and 17 glaucoma patients were included. Methods: High density optic nerve head (ONH) and macula OCT-A scans were obtained in patients with and without surgical masks. Seven different ...
