Concussion is a complex, yet to be fully understood brain injury that can have life altering consequences.
A person with a concussion will have vision problems which include double vision, poor eye tracking skills, difficulty looking from one point to another, difficulty maintaining a focus, reduced ability for the eyes to work together as a team, convergence insufficiency and possibly convergence excess.
Screening an athlete suspected of having a concussion is a difficult task loaded with responsibility. In a perfect world every sporting event would have a trained professional on hand in case an injury occurs. That ideal is not often possible.
Trainers, coaches and physicians observe eye muscle movements when assessing a concussion. When a trained professional is not available, having a C-Rod on hand could prove to be useful for screening purposes as an athlete coming off the field and having the onset of distressed saccadic eye movements is likely to have a concussion.
If an injured athlete cannot perform the 6 C-Rod eye exercises without distress then the player should be removed from play.
Part of "return to play" protocol should include an athlete regaining all oculomotor function free of distress.
