Eye Movement Recordings in the Diagnosis of Traumatic Brain Injury

Eye movements are recorded for Operations Enduring Freedom or Iraqi Freedom (OIF/OEF)
veterans with mild traumatic brain injury (mTBI) and compared to the eye movements of those
without mTBI. By analyzing and characterizing the differences between the two groups, a
diagnostic measure of mTBI through the use of eye movements can be developed.

Inclusion Criteria:

- OIF/OEF Veteran;

- Neuropsych diagnosis of MTBI

Exclusion Criteria:

- chronically abusing alcohol or illicit drugs.

- uncorrected vision prevents subject from effectively viewing the stimuli, unless they
can wear contact lenses during the recording session.

- inability to make normal eye movements (i.e.: saccades, smooth pursuit) required by
study paradigms. Note: Deficit can be caused by taking medications that can
potentially affect eye movements or any neurological condition that can interfere
with making normal eye movement.

- psychological or psychiatric conditions that preclude sustained concentration or
ability to perform the tasks.
