Brief Summary:
The purpose of this study is to determine the sensitivity and specificity of an aid in assessment of concussion based on eye-tracking, in comparison to a clinical reference standard appropriate for the Emergency Department (ED) or concussion clinic.

Group/Cohort Intervention/treatment
Potential Traumatic Brain Injury
This group will consist of people admitted to the ER, Trauma Bay, or Neurosurgery for potential traumatic brain injury.
Device: EyeBox CNS

Primary Outcome Measures :
  1. A change in metrics of eye movement that enable positive concussion detection using BOX Score. [ Time Frame: Immediately after eye tracking, within 2 weeks of injury ]
    A True Positive rate for identifying Concussion as compared to a Clinical Reference standard.

Secondary Outcome Measures :
  1. Change in Cognitive Function and Symptom Severity during Recovery as Measured with a Clinical Reference Standard for Concussion. [ Time Frame: Immediately before eye tracking, between 1 week and 109 weeks post injury ]

Ages Eligible for Study:   5 Years to 67 Years   (Child, Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Probability Sample
Study Population
Participants will include all patients evaluated for potential traumatic brain injury presenting to the Emergency Department or concussion clinic.

Inclusion Criteria:

  • Provide written informed consent.
  • Be between the ages of 4 and 67 years old.
  • Have a diagnosis of traumatic brain injury with a potential for concussion.
  • Subjects must have baseline vision correctable to within 20/500 bilaterally.
  • Subjects must have intact ocular motility.
  • Subjects must have ability to provide a complete ophthalmologic, medical and neurologic history as well as medications/drugs/alcohol consumed within the 24 hours prior.

Exclusion Criteria:

  • ER visit has been more than 2 weeks since the injury which may have caused the concussion.
  • Have received penetrating trauma or have a head CT demonstrating evidence of acute brain injury (subdural, epidural or intraparenchymal hemorrhage, edema/mass effect per attending radiologist read).
  • Suffering burns, anoxic injury or multiple/extensive injuries resulting in any medical, surgical or hemodynamic instability.
  • Blind (no light perception), are missing eyes, do not open eyes.
  • It is pertinent that subjects be able to detect light and have both eyes in order for the eye tracking data to be effective and significant.
  • Previous history of: ocular motility dysfunction or extensive prior eye surgery.
  • Any physical or mental injury or baseline disability rendering task completion difficult.
  • Obvious intoxication or blood alcohol level greater than 0.2.
