Glycocalyx on the giant vacuoles.
In bovine eyes, glycocalyx only sparsely coated the outer membrane, not the inner membrane of a giant vacuole (GV) of aqueous plexus (AP) endothelium whether a basal opening was not present (A) or present (B, arrowhead). The same is true in human eyes; glycocalyx is usually seen only coating the outer membrane but not inner membrane of a GV of Schlemm’s canal (SC) endothelium whether a basal opening is not observed (C) or is observed (arrowhead, D). More uniform glycocalyx was seen on the outer membrane of GVs in human eyes than in bovine eyes.
