Surgery on the Trabecular Meshwork: Histopathological Evidence
Juxtacanalicular (JXT) trabecular meshwork and endothelial lining of Schlemm's canal have been cited as the loci of aqueous outflow resistance, both in a normal as well as a glaucomatous eye. In this review, we attempt to understand the currently available surgical modalities in light of the available histopathological evidence, regarding localization of outflow resistance. How to cite this art...
متن کاملMatrix GLA protein function in human trabecular meshwork cells: inhibition of BMP2-induced calcification process.
PURPOSE The matrix GLA (MGP) gene has been found to be among the 10 most highly expressed genes in the human trabecular meshwork (TM), and its expression is affected by conditions associated with glaucoma. Because MGP protein has been shown to play a key role in inhibiting calcification in cartilage and arterial vessels, MGP's function in human TM was investigated. METHODS Perfused TM tissue ...
متن کاملEvidence for multiple P2Y receptors in trabecular meshwork cells.
The purpose of this study was to determine whether functional purinergic P2 receptors are present in trabecular meshwork cells. The human trabecular cell line HTM-3 and cultured bovine trabecular cells were used to assess the effects of P2 agonists on intracellular Ca(2+) levels, extracellular signal-regulated kinase (ERK1/2) activation, and P2Y receptor expression. ATP, UTP, ADP, and 2-methyl-...
متن کاملCalf Trabecular Meshwork
Superoxide dismutase and catalase activities have been measured in cell-free extracts of calf trabecular meshwork, and for comparison, in calf iris, retina, lens, liver, and erythrocytes. Gel electrophoresis has been used to identify isozymes of each enzyme. The superoxide dismutase and catalase activities per milligram wet weight of calf trabecular meshwork, 0.184 and 0.884 U/mg wet wt, respec...
متن کاملTrabecular meshwork and outflow
Core Concepts • iOP elevation results from increased outflow resistance in the outflow pathways: the trabecular meshwork (TM) and the uveoscleral pathway. • steady-state iOP is found in normal eyes where iOP builds up in response to inflow of aqueous humour to the level sufficient to drive fluid across the resistance of the outflow pathways. • in most glaucomatous eyes, the resistance of the ou...
