In veterinary ophthalmology, little is known about keratometry in dogs, and its practical application has been limited. The present study aimed to describe keratometry in some dog breeds popular in Japan using a handheld keratometer.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Client\u2010owned dogs of various signalment were enrolled prospectively in the keratometry examination. Interbreed variations in mean corneal curvatures (R1R2avg) and corneal astigmatism (\u0394(R1\u2212R2)) were evaluated statistically with respect to their bodyweight based on the data which fulfilled the predetermined inclusion criteria. P&lt;0.05 was considered statistically significant.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>On examination of 237 dogs from 16 different breeds, R1R2avg (mean\u00b1sd) ranged from 7.54\u00b10.30\u2009mm in Pomeranians to 9.28\u00b10.19\u2009mm in golden retrievers. \u0394(R1\u2212R2) (mean\u00b1sd) ranged from 0.22\u00b10.11\u2009mm in miniature schnauzers to 0.57\u00b10.30\u2009mm in French bulldogs.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The present study successfully described keratometry in 16 dog breeds. The study revealed considerable interbreed variations in both R1R2avg and \u0394(R1\u2212R2), which did not necessarily correlate with bodyweight.
