Ultrasonic pachymetry was used to measure central, superior peripheral, and temporal peripheral corneal thicknesses of 75 dogs (150 eyes) with normal corneas, anterior chambers, and intraocular pressure. Mean corneal thickness averaged over the 2 eyes, 3 locations, and 75 dogs was 562 +/- 6.2 microns. The peripheral cornea was thicker on average than the central cornea by 49.43 +/- 8.45 microns and this difference increased with age at 6.97 +/- 1.3 microns/month of age. Mean corneal thickness changed with age (14.23 +/- 2.26 microns/month), and weight (1.83 +/- 0.38 microns/kg). Females had significantly thinner corneas (22.43 +/- 11.03 microns than males) after adjusting for age and weight.
