This, in turn is drained by the collector channels and aqueous veins
, which empty into the conjunctival veins.
Canaloplasty is a relatively new nonperforating blebless technique, quite similar to Stegmann's viscocanalostomy , in which a 10-0 prolene suture is positioned and tensioned within Schlemm's canal after the injection of a small amount of high viscosity sodium hyaluronate, thus facilitating aqueous outflow through natural pathways (collectors channels and aqueous veins) [2-12].
The Heidelberg Retina Tomograph (HRT) cornea module clearly showed postoperative enlargement of aqueous veins and episcleral vessels in all successful eyes (Figure 11).
The conventional route of aqueous outflow involves movement of aqueous humour through the trabecular meshwork, a connective tissue which acts like a filter, across the inner vascular-like endothelial wall of Schlemm's canal, into collector channels and finally out of the eye in episcleral veins via the aqueous veins
. The outer portion of the trabecular meshwork is known as the juxta-canalicular meshwork and the outer endothelial layer forms the inner wall of Schlemm's canal.
