Salzmann,1 in 1912, published his classic text on the anatomy and histology of the eyeball, summarizing existing knowledge and describing the results of his own investigations. Little has been added to his description of the trabecular meshwork until recent years.

The trabecular meshwork has been considered to be composed of a uveal and a corneoscleral portion. The uveal meshwork borders the anterior chamber and its netlike fibers extend in an arc from the surface of the corneoscleral meshwork to the root of the iris. The meshwork is loose with large and irregular openings; the fibers appear rounded in cross section. The corneoscleral meshwork comprises the major portion of the trabeculae. The trabecular meshwork roughly is ring-shaped and in cross section is somewhat triangular, the apex being at the end of Descemet's membrane and the base of the triangle extending along a line between the scleral spur and the sclera
