Systemic or local use of glucocorticoids (GCs) can induce pathological elevation of intraocular pressure (IOP), potentially leading to permanent visual loss. Previous studies have demonstrated that rapamycin (Rapa) inhibits the activation of retinal glial cells and the production of neuroinflammation, achieving neuroprotective goals. However, there has been little research on the effect of Rapa on the trabecular meshwork (TM).

Precis: Perspectives and practice patterns regarding perioperative anticoagulation management and minimally invasive glaucoma surgery were queried among surgeons of American Glaucoma Society. Management varied based on surgeon preference and type of procedure performed.
Purpose: The purpose of this study was to characterize anticoagulation and antiplatelet practice patterns for minimally invasive glaucoma surgery (MIGS) in the perioperative period.
Association of Matrix Metalloproteinases Polymorphisms with Glaucoma Risk, Glaucoma Phenotype, and Response to Treatment with Selective Laser Trabeculoplasty or Latanoprost.

In open-angle glaucoma, the increase in intraocular pressure (IOP) is caused by an increased resistance to aqueous humour outflow in the trabecular meshwork. Since genetic variability of matrix metalloproteinase (MMP) genes may influence extracellular matrix remodelling, we investigated their association with glaucoma risk and/or response to treatment. The retrospective part of the study included patients with primary open-angle glaucoma and ocular hypertension (OHT); in the prospective part of the study, newly diagnosed patients with POAG or OHT were randomised to receive either latanoprost or selective laser trabeculoplasty (SLT) as the initial treatment.

Primary open-angle glaucoma (POAG), if caused by elevated intraocular pressure (IOP), may require a trabeculotomy (LOT), in which the trabecular meshwork (TM) and Schlemm's canal (ISC) are incised. However, the association between the incision angle and outcomes remains unclear. Therefore, in this study, we investigated the surgical outcomes of a trabeculotomy combined with cataract surgery in patients with POAG over a 12-month follow-up period.
View Article and Find Full Text PDFGlaucoma is a leading cause of irreversible blindness, often associated with elevated intraocular pressure (IOP) due to trabecular meshwork (TM) dysfunction. Diabetes mellitus (DM) is recognized as a significant risk factor for glaucoma; however, the molecular mechanisms through which hyperglycemia affects TM function remain unclear. This study investigated the impact of high glucose on gene expression in human TM (HTM) cells to uncover pathways that contribute to TM dysfunction and glaucoma pathogenesis under diabetic conditions.
