[Objective evaluation of the visual field defects in a patient with cerebral infarction using multifocal VEPs].
OBJECTIVE
We investigated whether visual field defects can be objectively evaluated using multifocal visual evoked potentials (mVEP) in a patient with cerebral infarction in whom it is difficult to measure the visual field.


METHODS
To determine normal waves in mVEP recording was performed using a VERIS Junior Science (Mayo, Aichi, Japan) in 20 healthy subjects (20 eyes), peak latency and amplitude were used for assessment. In a patient with cerebral infarction, mVEP were recorded, and compared with the lesion observed by computed tomography.


RESULTS
In 20 healthy subjects, the waveforms in the nasal and temporal quadrants were very similar but the waveforms in the superior and inferior quadrants were mirror images. The mVEP in patient with cerebral infarction showed abnormal waves, corresponding to the visual field defects in the lesion observed by computed tomography.


CONCLUSIONS
Objective evaluation of visual field defects using mVEP may be useful in patients with cerebral infarction in whom kinetic/static perimetry as a subjective examination is difficult.
