Eye Testing Device Could Help Soldiers, Doctors Diagnose Traumatic Brain Injury

By Hardwick & Pendergast, P.S. on March 8, 2012

A simple computerized device developed by the U.S. Army could help field medics, emergency medical technicians, doctors, and even sports coaches check for signs of traumatic brain injuries like concussions in order to speed treatment, according to a recent article posted on the Army website.

The device, known as Eye-Tracking Rapid Attention Computation or EYE-TRAC, consists of a piece with a screen, worn over the eyes, and a hand-held device that gives information readouts. The person who may have a traumatic brain injury wears the headpiece and tries to follow a moving target on the screen. The device tracks the person’s eye movements and sends information to the hand-held device, based on calculations of how well the person can track the moving target on the screen and what eye movements are made during the attempt.

Eye movements are often impaired when a concussion or other brain injury occurs, but human vision can’t always detect them merely by watching the patient. The EYE-TRAC device is more sensitive, allowing it to pick up on impairments that might signal a traumatic brain injury. Read the rest »
