[Aging of macular function as seen in multifocal electroretinograms].

Multifocal electroretinograms were recorded from 32 eyes of 32 young and aged healthy volunteers to investigate the change in electrophysiological functions with age in the central, nasal, temporal, superior, and inferior retina. The amplitude and latency of the first negative and positive waves were analyzed statistically in correlation with age. In all regions, amplitudes of focal responses tended to diminish with age. There was significant inverse correlation between amplitude and age in the central retina at 2 and 8 degrees, but no significant correlation was found in the other regions. These facts suggest that the macular retina tends to show functional deterioration with age when compared with other retinal areas.
