Eye-tracking technology presents promising biomarkers for identifying traumatic brain injury

What can eyes tell us about the brain? A recent report has found that horizontal and vertical self-paced saccades – the rapid movements of the eye between fixation points – act as a biomarker of traumatic brain injury (TBI). To test this hypothesis, researchers compared the horizontal and vertical saccades of people with no history of TBI and patients with a clinical diagnosis of TBI using RightEye eye-tracking technology. A total of 287 clinically verified participants, reporting either no TBI, mild, moderate or severe TBI participated in the tests. They concluded that eye tracking was an objective and quantifiable way of measuring not just the presence of TBI, but also the severity of the condition.
