Multifocal visual evoked potentials (MVEP) across the central visual field of 8.6 degrees of arc were tested in 31 normal eyes. It was observed that the mean response densities of the MVEP reduced with the increasing eccentricity; and were higher in the lower hemifield than those in the corresponding mirror symmetric locations in the upper hemifield. The incidence of polarity reversal was higher in the upper hemifield. The variation of the MVEPs across the visual field reflects the underlying anatomy of the retina and the visual cortex.
