New technology that tracks the eye movements of patients may be a more accurate measure of brain injury than any other diagnostic measurements currently in use, according to a study recently published in the journal¬†Concussion. Dr. Uzma Samadani, who recently joined the faculty at Hennepin County Medical Center, in collaboration with researchers at the Steven and Alexandra Cohen Veterans Center at NYU Langone Medical Center, developed the technology that can serve as a biomarker for concussion by tracking patients’ eye movements as they watch music videos.

The eye tracking technology works by having patients watch a music video for 220 seconds while eye movements are measured using a tracking camera. Videos used in the study ranged from Disney’s Puss in Boots to Wavin Flag by K’Naan. Multiple measures of each eye’s movement, followed by comparisons of their positions over time are used to distinguish between normal subjects and those with concussion.
