a) Schematic of binary classification process (top). Unmarked AS-OCT images were used as inputs to the convolutional neural network (CNN) classifiers. Gonioscopy grade probabilities (p₀ to p₄) were summed to make the binary prediction of angle status: angle closure = grades 0 and 1, open angle = grades 2, 3, and 4. b) Representative AS-OCT images corresponding to open (bottom left, grade 4) and closed (bottom right; grade 0) angles based on gonioscopic examination.
