Volumetric limbal reconstruction. SBA-labeled samples were visualized as maximum intensity projections (MIPs) of the superior (A) and inferior (B) limbus as seen from the anterior. In this right eye, nasal limbus is shown at the right and temporal at the left (A, bottom right). MIPs A2 and B2 show fine elements of the aqueous humor outflow tract distal to the TM as seen from the anterior chamber angle, viewed through the cornea and facing the z-plane. A3 and B3 show surface reconstruction and labeling of morphology with TM in yellow, CC in red, and SVP in blue. A4 and B4 show merged with corresponding surfaces set to 50% transparency. Vertical, solid white lines demarcate boundaries within which representative sagittal subregions (A, B 2.1, 3.1, 4.1) are segmented and positioned with the Z plane facing inward. ES, episclera.
