PupilScreen Output

Caption

PupilScreen combines a smartphone's flash and video camera with machine learning tools to track how the eye's pupil reacts to light. The app can currently distinguish between the pupillary light reflex of healthy people (shown above) and patients with severe traumatic brain injury. Additional studies this fall will help determine what characteristics are most useful in detecting milder concussions.
