Parts
The meshwork is divided up into three parts, with characteristically different ultrastructures:
- Inner uveal meshwork - Closest to the anterior chamber angle, contains thin cord-like trabeculae, orientated predominantly in a radial fashion, enclosing trabeculae spaces larger than the corneoscleral meshwork.
- Corneoscleral meshwork - Contains a large amount of elastin, arranged as a series of thin, flat, perforated sheets arranged in a laminar pattern; considered the ciliary muscle tendon.
- Juxtacanalicular tissue (also known as the cribriform meshwork) - Lies immediately adjacent to Schlemm's canal, composed of connective tissue ground substance full of glycoaminoglycans and glycoproteins. This thin strip of tissue is covered by a monolayer of endothelial cells.
The trabecular meshwork is assisted to a small degree in the drainage of aqueous humour by a second outflow pathway, the uveo-scleral pathway (5-10% of outflow occurs this way). The uveo-scleral pathway is increased with the use of glaucoma drugs such as prostaglandins (e.g., Xalatan, Travatan).

Famous quotes containing the word parts:
“Thus Satan talking to his neerest Mate
With Head up-lift above the wave, and Eyes
That sparkling blaz’d, his other Parts besides
Prone on the Flood, extended long and large
Lay floating many a rood, in bulk as huge
As whom the Fables name of monstrous size,
Titanian, or Earth-born, that warr’d on Jove,
Briarios or Typhon, whom the Den
By ancient Tarsus held, or that Sea-beast
Leviathan,”
—John Milton (1608–1674)
“How often we must remember the art of the surgeon, which, in replacing the broken bone, contents itself with releasing the parts from false position; they fly into place by the action of the muscles. On this art of nature all our arts rely.”
—Ralph Waldo Emerson (1803–1882)
“Here I am.... You get the parts of me you like and also the parts that make you uncomfortable. You have to understand that other people’s comfort is no longer my job. I am no longer a flight attendant.”
—Patricia Ireland (b. 1935)
