This study was aimed to investigate the main morphological components of the eyes in local Iraqi buffalos. Ten pairs of eyeballs were collected from a local slaughterhouse for anatomical observations. The Biomedical measurements were recorded and then these spacemen were fixed in 10% formalin. The rostral surface of the buffalo eyeball was protected by upper and lower eyelids, lined by thin, moist pink mucous membrane, conjunctiva. The cartilage of the third eyelid has a wing-like shape piece cartilage. The eyeball of buffalo is semispherical in shape, with a flat posterior surface. The sclera is penetrated by the optic nerve at the posterior part ventral to the median plane. The cornea is elliptical, the medial end is wider than the lateral end; the horizontal corneal diameter is longer than the vertical corneal diameter and the thickness of the cornea was more in central than in peripheral. The choroid is a thin dark or black-pigmented membrane located between the sclera and retina and continuous rostrally as iris and ciliary body. A well-developed metallic shiny bluish teptum lucidium was formed the dorsal half of the choroid. The retina was thin and easy to lose during fixation. The iris is a delicate diaphragm that has a central foramen by the pupil. The vertical axis of the pupil is shorter than horizontal axis. The posterior surface of the lens is more convex than the cranial surface. The lacrimal gland of buffalo appears as amass of glandular tissue located in dorso-lateral angle of the eye inserted between bony orbit and eyeball. The muscles responsible for move the eyeball are the rectus group; dorsal, ventral, medial and lateral muscles, the dorsal and ventral oblique muscle, the retractor oculi muscle also is appears surrounded by the optic nerve.
