Abstract: The objective of this study was to demonstrate the specific blood velocity parameters called peak systolic velocity (PSV), end diastolic velocity (EDV) and the resistive index (RI) in the internal ophthalmic artery (IOA) and the long posterior ciliary artery (LPCA) with color Doppler imaging (CDI) in clinically normal dogs. Eight healthy dogs were used in the study. Color Doppler ultrasonography was performed on both eyes. PSV, EDV and RI measurements were obtained for both eyes. The mean RI of the IOA was 0.57 ± 0.095 cm/s and that of the LPCA was 0.58 ± 0.083 cm/s. The RI values did not differ significantly between the right and left eyes. As a result, since CDI is a reliable and easily applicable method for detecting eye vessel blood velocity parameters, such as the IOA and LPCA, it can be recommended for investigating ophthalmic vessel disorders in dogs.
