Research Interests:

Glaucoma is a leading cause of blindness worldwide. A primary risk factor for the development and progression of primary open-angle glaucoma (POAG) is elevated intraocular pressure (IOP), which results from increased resistance to aqueous outflow. However, the cause of this resistance remains unknown. The research in Dr. Gong’s laboratory is focused on developing new therapeutic strategies to lower IOP in glaucoma. This is done through understanding the mechanisms that regulate aqueous outflow resistance in normal eyes and how this resistance is increased in POAG. Dr. Gong’s laboratory has developed a novel fluorophore-guided method of studying the structure and function of the aqueous outflow system. This unique method uses the effective filtration area as a new parameter in examining the structural changes responsible for the reduced outflow in glaucomatous eyes. They are currently using this new method to investigate both the mechanisms of potential drugs, as well as novel micro-invasive surgical devices in the treatment of glaucoma.

Our current ongoing research projects include:

1. Cellular Physiology of the Aqueous Outflow Pathway (Funded by NIH/NEI)
The goals of this project are to determine the factors that regulate the effective filtration area in normal eyes and the changes in these factors responsible for decreased effective filtration area in eyes with ocular hypertension or POAG.

2. The Mechanical Basis of Primary Open Angle Glaucoma (Funded by NIH/NEI)
This is a research project in collaboration with Dr. Mark Johnson at Northwestern University. The goals of this project are to definitively determine whether increased stiffness of Schlemm’s canal endothelial cells leads to decreased inner wall porosity and consequently the increased aqueous outflow resistance characteristic of most cases of POAG.

3. Matricellular Proteins in Trabecular Meshwork Increase Intraocular Pressure (Funded by NIH/NEI)
This is a research project in collaboration with Dr. Douglas Rhee at Case Western Reserve University. The goals of this project are to examine the role of matricellular proteins in regulating extracellular matrix turnover in the trabecular meshwork, its effect on IOP, and the potential contributions of dysregulation of matricellular proteins to the pathophysiology of glaucoma.
