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.

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.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| A change in metrics of eye movement that enable positive concussion detection using BOX Score. | Immediately after eye tracking, within 2 weeks of injury | A True Positive rate for identifying Concussion as compared to a Clinical Reference standard. |
Secondary
| Measure | Time frame |
|---|---|
| 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 |
