trabecular meshwork

(redirected from intertrabecular spaces)

trabecular tissue of sclera

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.

When trabecular bone was graded for apparent change in the present research, it was observed that group A had widening of intertrabecular spaces with reduction in trabecular thickness.
Stollberger and Finsterer refined the definition as >3 trabeculations protruding from the LV wall apical to the papillary muscles, perfused intertrabecular spaces, and atwolayered myocardium with the noncompacted layer usually thicker than the compacted myocardium in end-systole [21].
There diagnostic criteria were as follows: (1) >3 prominent trabecular formations along the left ventricular endocardial border, which are visible in end-diastole, distinct from papillary muscles, false tendons, or aberrant bands, (2) trabeculations move synchronously with the compacted myocardium, (3) trabeculations form the noncompacted part of the two-layer myocardial structure, best visible at endsystole, and (4) perfusion of the intertrabecular spaces from the ventricular cavity is present at end-diastole on color-Doppler echocardiography or contrast echocardiography.
It is believed that the vascular anomaly is a result of the abnormal persistence of intertrabecular spaces within the embryonic myocardium.
4,5) Trabeculae of bone are often lined by normal osteoblasts and osteoclasts, and intertrabecular spaces are often filled with normal connective tissues, including adipose, cartilage, and hemopoietic tissue.
The OVX animals showed sparse, uniform thinning of the trabeculae resulting in widened intertrabecular spaces (Fig.
In addition to these echocardiographic findings, prominent muscular trabeculations and deep intertrabecular spaces communicating with the ventricular cavity were observed in the infero-postero-lateral region and apical portion of the LV chamber (Fig.
More developed lesions, which are much less common and often lytic, show fibrosis of the intertrabecular spaces infiltrated by numerous small lymphocytes and scattered, large, transformed cells.
Deep intertrabecular spaces communicating with the main ventricular cavity were evident on both two-dimensional and colour flow imaging.
4) Occasionally mucoidlike tissue can be seen grossly within the intertrabecular spaces of the lesion.
