Abstract:
Objective To research the relationship between flash visual evoked potentials (fVEP)and intracranial pressure (ICP),to evaluate the usefulness of baseline fVEP testing in the diagnosis of increased ICP Methods 22 normal individuals,44 increased intracranial pressure patients and other 35 patients which were measured by lumbar puncture were recorded with fVEP The latency of their waves were compared Results A positive correlationship between elevated intracranial pressure and a latency shift of the P 2,N 2,P 3,N 3 wave of the flash evoked potential is demonstrated( P
