For many causes of blindness, a device to restore sight by sending signals from an external camera directly to the brain is the most promising treatment path. We have been using computerized simulations of artificial vision with normal, sighted subjects to answer questions about device design, and gaze tracking is a critical part of those studies. In this presentation, we will review our studies that have used a variety of gaze tracking systems and look to the future of visual prostheses.

Assistant Professor of Neurosurgery, Massachusetts General Hospital
John S. Pezaris, Ph.D. has bachelor's and master's degrees in Electrical Engineering and Computer Science from MIT, and a doctoral degree in Computation and Neural Systems from Caltech. After post-doctoral training at Harvard Medical School, he joined the research faculty in the Department of Neurosurgery at Massachusetts General Hospital where he currently runs the Visual Prosthesis Laboratory. His research interests include basic investigation of the early visual pathway, with translational application to restoration of sight of the blind.
This study focuses on eye movement disorders, in particular nystagmus, and the possibility of using eye tracking as an established form of diagnosis tool.Learn more
