Assessment of tear meniscus using UHR-OCT. Automatic segmentation of the lower tear meniscus in a healthy subject. Calculated parameters (represented in yellow) are (A) the tear meniscus area, (B) height, (C) depth, and (D) radius of curvature. Green crosses represent the points used for the estimation of the radius of curvature. The yellow arrows indicate mirror artifacts of the true upper meniscus boundary due to internal reflectors in the optical setup of the system. This figure was reprinted from Stegmann et al.
