Abstract

visual deficits autonomic dysfunction
Visual and autonomic system disturbances are common after concussion and predict prolonged recovery in adolescents. Eye tracking is a potential rapid and objective supplement to current clinical assessments of these deficits in concussed adolescents. Participants aged 13 to 17 years were enrolled in an observational cohort study between August 2017 and January 2020. A total of 132 healthy control adolescents, 110 acutely concussed adolescents (≤28 days since injury), and 95 concussed adolescents with persistent symptoms ( > 28 days since injury) had their eye movements recorded binocularly while viewing a 220 second moving video. Eye tracking metrics were compared across the three groups using Kruskal‐Wallis tests. Bonferroni corrections were applied to account for multiple comparisons. Nine eye tracking metrics were associated with injury status. One measure of binocular alignment (acute v. control: P = .003, persistent v. control: P < .001) and one measure of saccadic movement (acute v. persistent: P = .03, acute v. control: P = .03, persistent v. control: P < .001) were associated with injury status. Cases had larger mean and median pupil size (acute v. control, P < .001; persistent v. control, P < .001) and greater differences in mean, median, and variance of (acute v. control: P < .01, persistent v. control: P < .01) left and right pupil size. Eight of these metrics were associated with injury status in females and none were different among males. Objective eye tracking technology may quickly and objectively identify vision and pupillary disturbances after concussion, thereby augmenting current clinical assessments. These metrics may be integrated into existing practice to monitor recovery in a heterogeneous adolescent concussion population and identify sex‐specific differences.
