Influence of the Age of the Month on Electroretinogram in Beagle Dogs

Abstract

To investigate for influence of the age of the month on electroretinogram (ERG) in beagle dogs, ERG was recorded in 20 beagle dogs (10 males and 10 females) at 6, 7, 9, 12, 16 and 18 months. ERG was recorded on the six light stimulation conditions, recommended by the International Society of Clinical Electrophysiology of Vision. As a result, the change of latency and amplitude was not seen at any age of the month. The ERG on the beagle dogs from 6 to 18 months was not influenced by the age of the month.
