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.
The osteogenic areas are composed of long trabeculae of woven bone associated with the same proliferation of fusiform stromal cells in the intertrabecular spaces. These stromal cells are fusiform, elongated with moderate nuclear atypias.
For further evaluation, echocardiogram was done that showed appearance of trabeculations and deep intertrabecular recesses (Figure 2), blood flow from ventricular chamber into intertrabecular spaces on doppler imaging (Figure 3), systolic thickness of compacted layer less than 8 mm (Figure 3), and ratio of noncompacted to compacted layer of >2 at end of systole (Figure 3) as well as diastole (Figure 4) consistent with noncompaction.
The histopathological study showed that the tissues from the OVX + CMC treated group were thinly scattered with wider intertrabecular spaces.
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].
In PMF JAK2 V617F, megakaryocytes had a larger cytoplasmic area (P = .04), more regular cytoplasmic circularity (P = .001), a lower percentage of megakaryocytes in clusters (P = .049), a lower percentage of megakaryocytes attached to bone trabeculae (P = .05), and a higher percentage of megakaryocytes in intertrabecular spaces (P = .05).
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.
