The trabecular meshwork is a porous tissue at the eye's drainage angle that allows aqueous humor to exit the anterior chamber. It filters fluid through layered beams toward Schlemm's canal. Flow resistance here helps set intraocular pressure. Balanced function keeps the front of the eye nourished and clear.

Tiny passages guide fluid into Schlemm's canal encircling the eye. This route connects the chamber to the venous system.
The trabecular meshwork is a porous, triangular structure made of collagen beams lined by endothelial cells. It consists of uveal, corneoscleral, and juxtacanalicular zones arranged from inner to outer margins. The spaces between the beams form channels for aqueous humor outflow. Elasticity and cellular tone regulate flow toward Schlemm's canal.
The trabecular meshwork is a spongy tissue located near the cornea and iris that drains aqueous humor from the eye. It helps regulate intraocular pressure by controlling fluid outflow through Schlemm's canal. Proper function of the trabecular meshwork is vital for preventing glaucoma and maintaining clear, healthy vision.
Understanding the anatomy of the eye helps explain how vision works and why each part is important for healthy sight. From the cornea that focuses light to the retina that captures images, every structure plays a precise role. Learning about these components encourages better eye care and awareness of changes that could signal a problem.
Layered sheets and pores slow fluid just enough to control pressure while allowing steady outflow. Cells within the mesh adjust resistance by remodeling matrix and clearing debris. This self tuning maintains a stable environment. Smooth drainage supports optical quality and comfort.
They examine the angle with a gonioscope and may use imaging to infer structure. Pressure measurements and flow tests add context. Together, findings show how easily fluid exits. Clear assessment guides tailored care plans.
It is central to maintaining a healthy pressure range in the eye. Balanced resistance protects delicate optic nerve fibers downstream. Consistent outflow reduces fluctuations that can blur vision. The meshwork's role is fundamental to day to day clarity.
Is it a true filter? It regulates flow rather than trapping most particles.
Can it be seen without tools? No, angle viewing requires special lenses.
Does everyone have the same resistance? No, it varies among individuals.
