Comparison set
Multiple thousands of subjects spanning across concussion through severe TBI (including open head wounds).
Science
The wiring of the eyes is not a metaphor.
Saccades, pursuit, and fixation are "hard coded" in the brain, and TBI disrupts those circuits in a reliable and consistent manner. Record those movements properly, compare against the world's largest database of normal eye movemets; and the courtroom finally has a method to easily determine if a TBI has occured or not.
Through two decades of in-depth human research — much of it at the Hunter Holmes McGuire VA Medical Center in Richmond, with colleagues at Virginia Commonwealth University — this practice developed a novel, patented method capable of supporting or refuting the presence or history of TBI with very high accuracy.
The underlying RightEye Vision System received FDA Breakthrough Device designation. VCU named Dr. Gitchel Inventor of the Year in 2019. The Federal Laboratory Consortium’s 2022 Impact Award was the first such honor, in more than forty years, given to a VA laboratory.
Peer-reviewed work associated with the program includes research on differential eye movements in mild TBI versus normal controls (Cifu, Wares, Hoke, Wetzel, Gitchel, Carne, Journal of Head Trauma Rehabilitation, 2015).
Output
Quantitative traces a jury can see, backed by statistical analysis; not just a neurologist's qualitative impression.
Differential
Method reliable across 30+ neurologic conditions, and very senstive to detecting malingering.
