Glaucoma is the leading cause of irreversible blindness throughout the world and the second leading cause of blindness overall in the USA. Increased resistance to aqueous humor outflow through the trabecular meshwork (TM) results in elevated intraocular pressure (IOP), the most important risk factor for glaucoma. Reduced TM cellularity is observed with age and correlates with increased outflow resistance and elevated IOP. Current therapies for control of IOP involve pharmacological reduction of aqueous production and surgical enhancement of outflow. But lowering of intraocular pressure by biological modification of TM function has remained elusive. Our research is currently focused on: identifying characteristics of trabecular meshwork stem cells in vitro and in vivo; investigating how the stem cells function in animal models of glaucoma; studying stem cell-based therapy for glaucoma using TM stem cells or other types of stem cells for autologous transplantation.
