This work was carried out on the cornea of the eyeball of the donkey, cow, buffalo, camel, sheep, goat, pig and dog. The following dimensions were measured: the outer and inner dorsoventral and mediolateral dimension, also the plain, weight and the volume of the cornea and fibrous coat were recorded. The morphometric studies include also thickness of the cornea and its different layers centrally and peripherally. Generally, the thickness of the cornea is about 0.5–0.8 mm, the thickest cornea was observed in cow followed by pig and donkey, the thinnest cornea was observed in sheep followed by camel, goat and buffalo, while the cornea of the goat and buffalo has nearly the same thickness. The biometry of the cornea has been useful for assessment of certain pathologic and congenital abnormalities such as microcornea, megalocornea moreover this measurement are of utmost important when superficial keractectomy and keratoplasty are indicated.
