Glaucoma is a leading cause of blindness, and elevated intraocular pressure (IOP) characteristic of glaucoma is caused by increased aqueous humor outflow resistance. Studies have localized the bulk of outflow resistance to particular regions along the outflow pathway — namely, the inner wall endothelium of Schlemm’s canal and its underlying juxtacanalicular tissue (JCT) [1] — but the hydrodynamic details of how aqueous humor flows through these tissues and how these tissues generate outflow resistance are not well understood.
