Study Title:

Pupil characteristics after acute mild traumatic brain injury.

What is the purpose of the study?

The purpose of this study is to test the hypothesis that pupil size and reactivity in individuals who have suffered a concussion within the last 48 hours will be significantly different than pupil responses in individuals who have suffered orthopedic injury or who have not suffered any injury. We’d also like to test the hypothesis that the effects of cognitive load, or multi tasking, to see if there is a difference between concussed individuals and those with orthopedic or no injury. And we will look one month follow up via a phone survey to review any persistent symptoms.
