Ultrasonographic findings of some ocular structures inCaspian miniature horse

Ultrasonography is a relatively easy, safe and non-invasive examination method which can be used indiagnosis of ocular disorders as complementary to routine ophthalmic examinations. As there has been no collated study undertaken on the normal measurements of ocular structures in Caspian miniature horse, obtaining these measurements could be a benchmark to diagnose some of the diseases and eye problems of this miniature breed. Transpalpebral ultrasonographic scanning of left and right eyes of six Caspian horses was performed using a 10-13 MHz transducer. Qualitative ultrasonographic findings of the eyes were described and measurements of the ocular structures were obtained. Mean ± standard deviation of the anterior-posterior length of the eye axis, thickness of the lens, depth of the anterior chamber and depth of vitreous were as 32.9 ± 1.0, 10.8 ± 0.8, 3.0 ± 0.5 and 18.3 ± 1.0 mm, respectively.
