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:
“All are but parts of one stupendous whole,
Whose body Nature is, and God the soul;”
—Alexander Pope (1688–1744)
“He could jazz up the map-reading class by having a full-size color photograph of Betty Grable in a bathing suit, with a co- ordinate grid system laid over it. The instructor could point to different parts of her and say, “Give me the co-ordinates.”... The Major could see every unit in the Army using his idea.... Hot dog!”
—Norman Mailer (b. 1923)
“I’m an expert in hookers. I’m an expert in doormats. I’m an expert in victims. They were the best parts. And when I woke up—sociologically, politically, and creatively—I could no longer take those parts and look in the mirror.”
—Shirley MacLaine (b. 1934)
