Eye tracking measures brain injury severity

NYU‘s Uzma Samadan has developed an eye tracking device that measures the severity of concussion or brain injury.  This simple, inexpensive technology could improve the speed and accuracy of TBI diagnosis.

Researchers compared 64 healthy control subjects to 75 trauma patients at Bellevue Hospital. Pupil movement was tracked for 200 seconds while patients watched a music video.

The study showed that 13 patients who had hit their heads and had CT scans showing new brain damage, and 39 patients who had hit their heads and had normal CT scans, had significantly less ability to coordinate their eye movements than uninjured control subjects. 23 subjects who had bodily injuries but did not require head CT scans had a similar ability to coordinate eye movements as uninjured controls.
