The following showcases examples of testing completed using the novel technique developed by Dr. Gitchel. By tracking eye movements, the tests below provide examples of a healthy individual and someone with a moderate traumatic brain injury. Numerous decades-long human trials conducted by Dr. Gitchel provide extensive expertise and the capability of stratifying head injuries from normal function to concussion, mild, moderate, to severe TBI. Normative data is based on the largest database of eye movements on the planet, with aged matched control data on over 46,000 individuals from age 6 to 92.
