The primary objectives are: 1) To demonstrate that measurements from visual stimulus and eye tracking system will predict the presence or absence of traumatic brain injury related vision disorder, i.e. oculomotor dysfunction (OMD) as diagnosed by a developmental optometrist (OD). 2) To use the eye tracking visual measurements to predict the effectiveness of neurovision rehabilitation (NVR) on post-traumatic OMD by comparing the data obtained to the objective visual measurements found on the OD examination.
