Summary

  • I am an ophthalmologist with a glaucoma tertiary care subspecialty practice of 37 years. I am passionate about the need to understand the regulation of aqueous outflow in glaucoma, how it fails, and how to restore it. I have had a research laboratory for the past twelve years studying aqueous outflow regulation. Our lab has collaborated with the UW Department of Bioengineering, Keck Microscopy Center, and Nanotechnology Center. We identify dynamically moving valves and chambers in the aqueous outflow system that permit pulsatile aqueous outflow. Using OCT in human subjects, we find tissue stiffening in glaucoma with loss of motion. Motion loss identifies the glaucoma process and can predict diurnal IOP fluctuations not apparent from daytime IOP measurements.
