Post-trauma vision syndrome (PTVS), which is characterized by binocular function problems, may be caused by dysfunction of the ambient visual process which is part of the sensory-motor feedback loop rather than specific oculomotor disturbance. Clinically, PTVS frequently presents with symptoms of diplopia, blur, seeing movement in the spatial environment, vertigo, and hallucination-like experiences. Visual evoked potentials (P100) were used to evaluate an experimental group (n = 10) of subjects who suffered a traumatic brain injury, and a control group (n = 10). A new treatment using prisms and bi-nasal occluders which affected amplitude responses of the VEP was evaluated. The results demonstrate the amplitude of the VEP is a function of cortical binocular integration, and that this is influenced by dysfunction of the ambient visual process. The results also demonstrate that base-in prism and bi-nasal occluders are an effective means to treat ambient vision disturbances resulting from head trauma which causes PTVS.
