Description
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.
