Normal ocular structure of dromedary camel (camelus dromedaries)‎ : gross, ultrasonographic and computed tomographic study

الملخص EN

The camel eye is studied by mean of ultrasound (US), computed topography (CT) and grossly.

US was performed by micro convex probe on B-mode either by transcorneal and transpalpebral techniques and the appearance was described and ocular dimensions were recorded.

Ocular sonographic appearance found similar to other species and the optic nerve appeared as a hypoechoic circular area next to the vitreous body at the far field of the image.

Biometrically, the cornea was thicker at the center than the periphery, lens diameter is more than thickness and the depth of vitreous body is less than the axial length of the globe.

CT images showed eye globe nearly radiolucent with some slightly radiopaque shades, the lens appeared as a highly opaque rounded spot, the bony orbit seen as an opaque rim encircling the globe and communicate with the nasal sinus medially at level of the medial canthus.

Grossly, the upper cilia were longer than the lower, tactile hairs seen on the medial canthus, fat tissue present in the eyeball, cornea and pupil were oval, presence of structure on the iris resembles granula iridica in equine and the tapetum is absent.
