Table 3: ERG amplitude and implicit time for normal and affected ESS dogs in the masked study. Median, 5th and 95th percentiles are given for ERG a- and b-wave amplitudes (a) in microvolts and in (b) for implicit times in milliseconds, for normal and affected ESS dogs. Scotopic ERGs consisted of scotopic low-intensity responses (S: 0.01 cd·s/m2), which were elicited 4, 8, 12, 16, and 20 minutes after dark adaptation designated: S1, S2, S3, S4, and S5, scotopic standard intensity responses, Ssd: 3 cd·s/m2, and scotopic higher intensity responses, Sh: 10 cd·s/m2. Photopic ERGs consisted of a photopic single flash response: Psd, and 30 Hz flicker responses: Pfl, using 3 cd·s/m2 for both, after at least 10 minutes of light adaptation using 30 cd/m2 of background light.
