The article presents the results of ultrasound examination of eyes in cattle in nor-
mal and uveitis animals. As a result of this work, we were able to assess the diagnostic value of
ultrasound for uveitis. In case of violation of the transparency of the optical media of the eye, this
diagnostic method is an integral part of the diagnosis and understanding of the development of
the disease process.
The main sonographic sign of uveitis is thickening of the choroid due to its swelling. It was
established that in the majority of sick animals in the vitreous body there were hyperechoic float-
ing opacities, which were absent in the paired eye. The size of the inflamed eyeball was several
millimeters smaller than that of the contralateral eye and 7 % smaller than that of the control
animals. The average thickness of the choroid in the posterior pole was 1,46 cm, which is 71 %
less than in healthy animals.
The advantage of this technique is its non-invasiveness, using ultrasound it is possible to carry
out a comparison and analysis of the anatomical structures of the eyeball, the orbit, to determine
their hemodynamic characteristics, which is particularly important in the study of opaque struc-
tures of the eye.
Keywords: cattle, uveitis, cornea, retina, ultrasonography, vitreous body, choroid.
