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.

Further study details as provided by VA Office of Research and Development:

Primary Outcome Measures:
  • Stability of Fixation [ Time Frame: During eye movement recording session (20 sec). ]
    The ability to keep eye position fixed on a visual target, measured by the distance between the target and eye fixation point averaged over 20 sec.

Enrollment: 26
Study Start Date: April 2011
Study Completion Date: June 2014
Primary Completion Date: December 2013 (Final data collection date for primary outcome measure)
Control subjects with no Mild Traumatic Brain Injury (MTBI) and no Post-Traumatic Stress Disorder (PTSD)
Subject with a diagnosis for Mild Traumatic Brain Injury (MTBI)

Detailed Description:
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.

Ages Eligible for Study:   18 Years to 55 Years   (Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes
Sampling Method:   Non-Probability Sample
Study Population
Adult betwenn 18 and 55 years old with and without a diagnosis of MTBI

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.
