Abstract/OtherAbstract:
The purpose of the study was to establish normal electroretinogram (ERG) parameters in 56 normal eyes of four common dog breeds in Thailand: Poodle, Labrador Retriever, Thai Ridgeback and Thai Bangkaew. Standard ERGs were bilaterally recorded using a handheld multi-species ERG unit with the ERG-jet lens electrode in 28 dogs under preanesthesia with diazepam, induction with propofol and anesthesia maintenance with isoflurane. There were significant differences in the means of ERG amplitudes and implicit times among the four dog breeds (P<0.05) except for the b-wave implicit time of the photopic 30 Hz flicker response with 3 cd.s/m(2) (P=0.610). Among all breeds, Thai Bangkaew had the longest implicit time (p<0.001) of scotopic low intensity responses, b-wave of scotopic standard intensity responses (3 cd.s/m(2)), a-wave of the higher intensity response (10 cd.s/m(2)) and a-wave of the photopic single flash response (3 cd.s/m(2)). For b/a ratio, only the ratio of the Cone response had a significant difference among dog breeds. This study reported normal ERG parameters in four dog breeds and supported that the breed-specific limits of normality to ERG response are necessary in each clinic and laboratory.
