connective tissue
The structure is composed of connective tissue beams and sheets or lamellae covered by TM cells. Three consecutive regions define the filtering portion of the TM: uveal meshwork, corneoscleral meshwork and juxtacanalicular region (JCT) also often called the cribriform region.
What is a trabecular meshwork?
The trabecular meshwork is the spongy tissue located near the cornea through which aqueous humor flows out of the eye. The trabecular meshwork lies in the drainage angle (see video above), and 80 – 90 percent of aqueous humor makes its way into circulation via the trabecular meshwork and its associated structures.
What blocks the trabecular meshwork?
Pigment dispersion, where tiny fragments or granules from the iris (the colored part of the eye) can circulate in the aqueous humor (the fluid within the front portion of the eye) and block the trabecular meshwork, the tiny drain for the eye’s aqueous humor.
What is the uveal meshwork?
The uveal meshwork extends from the ciliary body in the angle recess to Schwalbe’s line and covers the ciliary body face, the scleral spur, and the trabecular meshwork. In most eyes the uveal meshwork is colorless and is either not visible or is seen only as a glistening veil in the angle of young patients.
What is trabecular pattern?
Trabecular pattern of proximal femur refers to the five groups of trabeculae that are demonstrable within the femoral head and neck.
What blocks the trabecular meshwork in open angle glaucoma?
In open-angle glaucoma, the iris is in the right position, and the uveoscleral drainage canals are clear. But the trabecular meshwork isn’t draining properly. In closed-angle glaucoma, the iris is squeezed against the cornea, blocking the uveoscleral drains and the trabecular meshwork.
What does trabecular mean?
1 : a small bar, rod, bundle of fibers, or septal membrane in the framework of a body organ or part. 2 : a fold, ridge, or bar projecting into or extending from a plant part especially : a row of cells bridging an intercellular space.
What are the properties and functions of trabecular bone?
Trabecular bone transfers mechanical loads from the articular surface to the cortical bone. The hydraulic properties absorb shock. The material properties of the bone compartments differ: trabecular bone has lower calcium content and more water content compared to cortical bone.
What is the ciliary epithelium?
The ciliary epithelium of the ciliary processes produces aqueous humor, which is responsible for providing oxygen, nutrients, and metabolic waste removal to the lens and the cornea, which do not have their own blood supply.
What is the function of trabecular bone?
The general functional role of trabecular bone is to provide strength and transfer external load away from the joint and toward the cortical bone (Currey, 2002; Barak et al.
