PupilScreen: Using Smartphones to Assess Traumatic Brain Injury

University of Washington researchers are developing the first smartphone app capable of objectively screening athletes and others who may be suffering from concussion based on the pupillary light response. This reflex has been used to assess whether a patient has severe traumatic brain injury, and recent research indicates it can be useful in detecting milder concussions. The UW researchers plan to conduct field studies of PupilScreen with the help of coaches, emergency medical technicians, doctors and others, and use the data they collect to produce a commercially available version of the app within two years.
