Outcome Measures
Primary Outcomes (1)
A change in metrics of eye movement that enable positive concussion detection using BOX Score.
A True Positive rate for identifying Concussion as compared to a Clinical Reference standard.
Immediately after eye tracking, within 2 weeks of injury
Secondary Outcomes (1)
Change in Cognitive Function and Symptom Severity during Recovery as Measured with a Clinical Reference Standard for Concussion.
Immediately before eye tracking, between 1 week and 109 weeks post injury
Study Arms (1)
Potential Traumatic Brain Injury
This group will consist of people admitted to the ER, Trauma Bay, or Neurosurgery for potential traumatic brain injury.
Interventions
Eligibility Criteria
Participants will include all patients evaluated for potential traumatic brain injury presenting to the Emergency Department or concussion clinic.
You may qualify if:
- 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.
You may not qualify if:
- 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.
