In the human eye, the final barrier for aqueous humor to cross before returning to systemic
circulation is the inner wall of Schlemm's canal. Unfortunately, the specific contribution of the
inner wall to total outflow resistance in the conventional pathway is unknown in both normal
and glaucomatous eyes. To better understand inner wall physiology, we contrasted it with 2
specialized continuous endothelia, initial lymphatic, and blood capillary endothelia.
Specifically, we compare their developmental origin, morphology, junctional complexes …
