Normal ultrasonographic findings of the eye in Lori-Bakhtiari sheep

Using of ultrasonography is necessary to inspect and diagnose the disorder of internal structure of the eye in many ocular diseases. As there has been no collated study undertaken on the natural measurements of Lori – Bakhtiari sheep's eye, obtaining these measurements could be a benchmark to diagnose some of the diseases and eye problems of this breed. In order to undertake this study, the left and right eyes of twenty Lori – Bakhtiari sheep were evaluated by using ultrasonographic B-mode real time technique and normal ultrasonographic images of the eyes have been taken. After description of the images, measurements of the lens thickness, depth of anterior chamber, depth of vitreous and length of anterior- posterior axis of the eye were measured on the recorded images. The average and standard deviation of the measurements are recorded 0.79 ± 0.96cm, 0.23 ± 0.18cm, 1.09 ± 0.12cm, 2.16 ± 0.25cm respectively. There have been no significant between left and right eyes and between male and female sheep’s eyes (P≥0.05). The result of this study can be used as normal value measurements in ultrasonographic evaluation of Lori – Bakhtiari sheep's eye.
