Machine learning classification of retinal imaging of neuropsychiatric and healthy cases in a subset of the UK Biobank cohort

“…The compressed archives of OCT imaging contain 128 individual OCT B-scans, one of a handful of imaging types that OCT devices can produce (only OCT B-scans are available in UKBB). Readers are directed to comprehensive reviews and textbooks about the technical specifications of how OCT imaging is captured (Abràmoff et al, 2010;Aumann et al, 2019;Dahrouj et al, 2022;Schiffman et al, 2015); in sum, data about the speed at which light is reflected against the retina allows for quantification of retinal morphology. Eighteen-thousand A-scans (i.e., a single cross-sectional image of the retina) are collected per second during OCT imaging with the Topcon 3D OCT1000…”
