Measuring principle of the iridocorneal angle with AOS (Angel Opening Sequence) suggested by the authors in 2011. Each iris contour point (in red) is connected to a suitable corneal contour point (in yellow). A division into the appropriate contour is performed based on the point in the largest curvature (shown in black). In this way, a sequence of measurements at various distances from the apex of the measured angle is obtained.
