Eye Movement Recordings in the Diagnosis of Traumatic Brain Injury

The study investigates whether the use of eye movement recordings can provide a reliable diagnostic of previously undiagnosed mild traumatic brain injury (blast and impact) in Operations Enduring Freedom or Iraqi Freedom (OIF/OEF) veterans.

• No Intervention: Arm 1
  Screening for Inclusion - Neuropsych evaluation for Mild Traumatic Brain Injury (MTBI) with no Post-Traumatic Stress Disorder (PTSD)
• Experimental: Arm 2
  Diagnose for MTBI - patient eye movement is tracked while looking at lights
  Intervention: Other: Eye movement recording and analysis
• Arm 3
  Intervention - Eye movement training to improve reading performance
  Intervention: Other: Eye movement recording and analysis

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.
