Figure 1 (A) An AS-OCT image of the iridocorneal angle measured using AOD-SL, which can vary depending on the visibility of the image, identification of multiple landmarks, and slope of the curvature post Schwalbe’s line, (B) and the AS-OCT angle width measurement, the diameter of the largest circle that would fit between Schwalbe’s line and iris.
