Research Interests:

The broad goal of our research is to determine the principal site of aqueous humor outflow resistance in the normal human eye and to determine how this resistance is increased in primary open-angle glaucoma. Currently there are four ongoing research projects:

1. A potential target site to decrease outflow resistance (Funded by the American Health Assistance Foundation)
Major goals of this project is to better understand how the connectivity between the inner wall of Schlemm’s canal and underlying juxtacanalicular connective tissue (JCT) plays a role in regulation of outflow resistance and its potential mechanism in non-human and human eyes and to determine whether the inner wall and JCT separation can be induced in human eyes to decrease outflow resistance.

2. A study of the dynamics of Schlemm’s canal endothelial cells using a three-dimensional cell culture device with real-time imaging (Funded by the Glaucoma Research Foundation)
Major goals of this project is to modify and apply a three-dimensional cell culture device with real-time imaging recently developed at MIT to study the dynamics of cultured Schlemm’s canal endothelial cells from normal and POAG eyes.

3. New strategies for the development of glaucoma treatment (Funded by Boston University School of Medicine Wing Tat Lee Fund)
Major goals of this project is to establish a collaborative research and training program between Boston University School of Medicine and Huashan Hospital of Fudan University, Shanghai, China

4. Outflow Area and its Role in Glaucoma Pathogenesis (Funded by the American Health Assistance Foundation and the Massachusetts Lions Eye Research Fund, Inc.)
Major goals of this project is to determine whether increased outflow resistance in glaucoma could be related to an irreversible herniation of the inner wall and JCT into collector channel ostia and a diminished capacity for these eyes to recruit additional areas for outflow, as IOP changes.
