PURPOSE: We investigated whether visual field defects could be objectively evaluated using multifocal visual evoked potential(m-VEP) in two children with epilepsy caused by intracranial disease in whom it was difficult to measure the visual field. METHODS: To determine normal waves in m-VEP, recording was performed using a visual evoked response imaging system(VERIS)Junior Science program (Mayo, Aichi, Japan) in 20 healthy children (20 eyes); peak latency and amplitude were used for assessment. In the two children with epilepsy, m-VEPs were recorded, and compared with the results of static perimetry or the lesions observed by Magnetic Resonance Imaging (MRI). RESULTS: In the 20 healthy children, there was no significant difference in the peak latency or amplitude among 4 quadrants by one-way analysis of variance. m-VEP in the children with epilepsy showed abnormal waves, corresponding to the visual field defects in the static perimetry or the lesions observed by MRI. CONCLUSIONS: Objective evaluation of visual field defects using m-VEP may be useful in children with epilepsy caused by intracranial disease in whom kinetic/static perimetry as a subjective examination is difficult.
