From: Effect of digital ocular massage on intraocular pressure and Schlemm’s canal dimensions

Measurements of Schlemm’s canal (SC) area, SC diameter, trabecular meshwork (TM) thickness, and TM width. SC was outlined by yellow line and measured by delineating the lumen. SC diameter is the distance from the anterior endpoint to the posterior endpoint of the SC. TM width was measured from the scleral spur (SS) to the Schwalbe line (SL). TM thickness was calculated as the average of two measurements, the perpendicular distances from the anterior endpoint (A1) and midpoint (A2) of SC to the inner layer of the TM. (a) Dimensions at baseline (subject 011): SC area = 18,035.4 μm2, SC diameter = 456.1 μm, TM width = 849.8 μm, TM thickness = 139.5 μm. (b) Dimensions immediately after ocular massage (subject 011): SC area = 23,030.4 μm2, SC length = 430.8 μm, TM width = 880.6 μm, TM thickness = 155.4 μm.
