What information does this add to my diagnostic battery?

The main extra piece of information that the VEP/VER adds to ones diagnostic battery is a test of the neurology of the primary flow from the eye back to the primary visual cortex (V1). It is good to know as soon as possible whether or not there may be any frank neurological involvement that would preclude a positive outcome. One would very much like to know if there is an active problem that requires care from other disciplines. The VEP/VER does not answer all of these questions unequivocally, but it does add significantly to the clinical picture of these types of cases. It only takes one good recording to tell us the neurology is intact and the potential for improved vision exists.
