الشرح

This overlies Schlemm’s canal and is composed of collagen beams covered
by trabecular cells. The spaces between these beams become increasingly
small as Schlemm’s canal is approached.This meshwork accounts for most
of the resistance to aqueous outflow. Damage here is thought to be the
cause of the raised intraocular pressure in primary open angle glaucoma.
Some of the spaces may be blocked and there is a reduction in the number
of cells covering the trabecular beams .
Fluid passes into Schlemm’s canal both through vacuoles in its
endothelial lining and through intercellular spaces
