The cornea as a light refractive medium influences the optical aspects of vision. The thickness of the cornea is of surgical/ophthalmological importance. Its thickness is uneven and varies with breed, individual and age. The thickness of the cornea can be measured with ultrasonographic and optical pachymetry. In contrast to these earlier measuring techniques the OCT examination provides a great progress.

Our investigation involved OCT data of 274 anatomically sound dogs. Each eye was characterized with measurements from 3 concentric zones of octans and the centre. The average thickness was 568.89 in the centre, 573.66 in the mid zone and 574.11 at the periphery in micrometer.

During the analysis the data were sorted by the following parameters: age, gender, left/right side, fur colour, size and breed. Our results indicate higher thickness in males, elders, slightly in the right eye, in mid sized individuals and in light brown coloured ones.
