There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Title: Mechanical Properties of the Trabecular Meshwork
Abstract:
Glaucoma is an eye disease that can cause total permanent blindness without treatment. Elevated intraocular pressure (IOP) is the most important risk factor and the only proven treatment currently available for glaucoma is IOP reduction. Trabecular meshwork (TM) stiffness has been measured in previous studies and it is suggested that change of TM stiffness may play a role in IOP dysregulation. However, previous studies have limitations such as the use of completely excised TM and confounding effects of glaucoma medications. In this project, in Aim 1, we propose a specimen-specific FEM to estimate TM stiffness in a more physiologically relevant manner. In aim 2, we propose to investigate the relation between measured TM stiffness and outflow facility in mice. By accomplishing this project, it will answer the fundamental question of whether variation of TM stiffness contributes to the increased outflow resistance, leading to elevated IOP.
