ABSTRACT
Twenty-eight ocular bulbs of fourteen adult catheters were evaluated through ultrasound with the transpalpebral approach, using a standardized technique by the operator. Additionally, the hemodynamic study of the external ophthalmic artery was performed using the color Doppler technique. The collected data were statistically analyzed by the Bioestat 5.0 for Windows program, adopting 5% of significance. With the methodology employed, the following values were obtained for the right and left eyeballs, respectively D1: 1.72 ± 0.29mm and 1.76 ± 0.40mm; D2: 9.95 ± 1.08mm and 10.6 ± 0.99mm; D3: 7.42 ± 0.93mm and 7.45 ± 0.72mm and D4: 17.6 ± 0.78mm and 17.8 ± 0.59mm. The mean resistivity index values of the external ophthalmic artery were 0.435 ± 0.02 and 0.448 ± 0.02 (right and left eyeball respectively). There was no statistical difference regarding ocular antimers in any of the studied parameters. We concluded that ocular echobiometry and ophthalmic artery Doppler flowmetry in Tayassu tajacu species is executable and reproducible, provided there is an examiner's domain regarding the anatomy and proper technique. The values inferred in this study serve as a reference for veterinarians in the diagnosis of eye diseases.
