High-resolution iridocorneal angle OCT imaging, segmentation, and depth-encoding. (A) The example is an radial image, where the low-intensity prolate ellipse corresponds to the cross-section of a ring-shaped SC, which locates right above the TM. (B) The anterior surface was segmented and delineated in blue using a custom semi-automated algorithm. (C) The region outside of the surface boundary is blackened as zeros. (D) A depth-encoded image shows the rainbow effect starting from the segmented boundary into deeper tissues. TM: trabecular meshwork; SC: Schlemm’s canal; AC: anterior chamber.
