Comparison of central corneal thickness in dogs measured by ultrasound pachymetry and ultrasound biomicroscopy.

•Ultrasound biomicroscopy (UBM) and ultrasound pachymetry (UP) can be used interchangeably for measuring corneal thickness.•Differences in central corneal thickness (CCT) in healthy Beagle dogs measured by UBM and UP were approximately 5%.•The cornea was thicker in male dogs than female dogs and in dogs.•CCT was higher in male than female dogs, and in dogs weighing ≥15kg than in lighter dogs; sex was correlated with weight.
