Objective: Macroscopic study of different regions of one-humped camel eyes.
Design: Descriptive study.
Animals: Six pairs of eyes of six mature camel.
Procedure: Camel eyes were provided from semnan slaughterhouse, fixed in 10% formalin, dissected and studied. The layers of eye were studied by stereomicroscope. The cornea, lens and pupil were measured. Result: The ci1lia of upper eyelid are longer than lower eyelid in camel. There are many tactile hairs up the medial cantus of eye in the camel. The motion of upper eyelid is more than lower eyelid. Mean sixs of internal axis to external axis in cornea is around 2.92
in right and 2.93 in left eye. Mean sixs of dorsoventral axis of cornea is 2 in right eye and 1.95 in left eye of camel. All measurements are showen in tables.
Conclusion: There are adipos tissue in the ventral, ventromedial
and dorsomedial aspects of eyeball. This adipose tissue is cause of easy motion of third eyelid on the cornea of eyes. The cornea and pupil of camel eye are oval shape, but the medial poles are wider. The iris has a few folds in the dorsal and ventral borders. The folds of dorsal border of iris are greater. These folds are absent in other ruminant such as cattle. The tapetum is absent in the camel eye. J. Fac. Vet. Med. Univ. Tehran. 58, 4:313-318, 2003.
