Abstract

The orbital bony rim completely encircled the globe and projected above the surrounding bony surfaces. The orbital cavity reduced in its size ventrorostrally by the presence of the lacrimal bullae, which is the orbital diverticulum of the maxillary sinus inside the orbital cavity. The CT images and anatomical sections determine the most structures of the eye orbit as; eye lens, vitreous body of eye, anterior chamber, muscles of eye and peri-orbital fat. The lacrimal gland was clear and located on the dorsolateral surface of the orbit. The orbital cavity not closed by bone but limited by the coronoid process of the mandible and temporomandibular joint. There is one supra-orbital foramen and one wide infra-orbital foramen. There are two lacrimal notches on the rostrodorsal border of the orbital cavity. The frontal sinus has an orbital diverticulum that extended dorsally and ventrally around the orbital cavity. The maxillary sinus has two diverticulums inside the orbital cavity named the tympanic bulla.
