What kinds of cases could benefit from this information?

VEP/VER can be used with any patient. It yields the greatest insights when working with amblyopia, strabismus, non-malingering syndrome, and with some non-verbal patients. The loss of visual acuity associated with these conditions can mimic other conditions that may be secondary to neurological problems. Some have used the devices to monitor changes in binocularity before and after treatment, and to do a form of refraction in some cases. The VEP/VER can be helpful in determining if the loss of visual acuity is functional or developmental, and therefore more treatable, or if the loss is secondary to neurological damage.
