The goal of this study is to evaluate whether Optical Coherence Tomography Angiography (OCTA) has the potential to improve how moderate-to-severe primary open-angle glaucoma (POAG) is clinically monitored.
Optical Coherence Tomography Angiography (OCTA) is a novel method of measuring blood flow through the retina of the eye. FDA approval was obtained for OCTA in 2015. The reliability, reproducibility, and repeatability of OCTA have not been characterized in patients with glaucoma and normal eyes. OCTA parameters were highly repeatable during the same visit.
Traditional still cameras can only focus on a single plane for each image while rendering everything outside of that plane out of focus. However, new light-field imaging technology makes it possible to adjust the focus plane after an image has already been captured. This technology allows the viewer to interactively explore an image with objects and anatomy at varying depths and clearly focus on any feature of interest by selecting that location during post-capture viewing.
