trabecular meshwork


Also found in: Wikipedia.

trabecular tissue of sclera

[TA]
the network of fibers (pectinate ligaments) at the iridocorneal angle between the anterior chamber of the eye and the venous sinus of the sclera; it contains spaces between the fibers that are involved in drainage of the aqueous humor and is composed of two portions: the corneoscleral part (the part attached to the sclera) and the uveal part (the part attached to the iris).

trabecular meshwork

The fibrous basement membrane in the angle between the iris and the corneal-sclera junction. Aqueous humour exits the anterior chamber of the eye through spaces in the trabecular meshwork and enters the venous sinus of the sclera (i.e., the canal of Schlemm).

Trabecular meshwork

A sponge-like tissue located near the cornea and iris that functions to drain the aqueous humor from the eye into the blood.
Mentioned in: Glaucoma

meshwork, trabecular

Meshwork of connective tissue located at the angle of the anterior chamber of the eye and containing endothelium-lined spaces (the intertrabecular spaces) through which passes the aqueous humour to Schlemm's canal. It is usually divided into two parts: the corneoscleral meshwork which is in contact with the cornea and the sclera and opens into Schlemm's canal and the uveal meshwork which faces the anterior chamber. See phacolytic glaucoma; plateau iris; anterior limiting ring of Schwalbe; pigment dispersion syndrome.

02%, is a novel eye drop that the company believes, if approved, would become the only once-daily product available that, based on Aerie's preclinical and clinical studies to date, specifically targets the trabecular meshwork, the eye's primary fluid drain and the diseased tissue responsible for elevated IOP in glaucoma.
Latanoprostene bunod is believed to lower IOP by increasing outflow of aqueous humor through both the trabecular meshwork and uveoscleral routes, according to the companies.
In this condition, the angle in the eye where the iris meets the cornea is normal, but the eye's trabecular meshwork (its drainage canals) becomes clogged over time, causing an increase in IOP and damaging the optic nerve.
Due to increased AMPK activation, as the aqueous humor circulates, it comes in contact with trabecular meshwork and may cleanse the glycation around the endothelial cells of the trabecular meshwork, thus allowing the aqueous humor to pass to exits without resistance.
17) Blockage of the trabecular meshwork by pigment and PEX material, and trabecular cell dysfunction eventually result in elevated IOP, which leads to PEX glaucoma.

Mice with glaucoma were able to maintain normal intraocular pressure after receiving a stem cell transplant to restore their eye's trabecular meshwork.
Apposition of the iris to the trabecular meshwork is the consequence leading to elevated IOP and glaucoma [1].
The influx of cells regenerated the tiny, delicate patch of tissue known as the trabecular meshwork, which serves as a drain for the eyes to avoid fluid buildup.
The causes for raised IOP are deposition of capsular debris in the trabecular meshwork, inflammatory swelling of the ciliary body or iris root associated with angle closure, liquefied vitreous and shock wave damage to the trabecular meshwork.
