[Computed tomographic anatomy of the orbit in the view of a clinician].
The paper deals with the examination of computed tomograms of 72 patients (90 orbits), including 29 males (36 orbits) and 43 females (54 orbits), who had no any orbital pathology. The patients' age ranged from 34 to 65 years. Data on the volume of the bony orbit and its soft tissue contents are given. The dimensions of the transversal opening to the orbit and its depth are shown. The volumes of all the ocular muscles (extraocular muscles, the elevator muscle of the upper eyelid), optic nerve, eyeball, and ocular fat are separately calculated. These indices may be used for both the differential diagnosis of true exophthalmos and pseudoexophthalmos and the planning of any orbital surgery.
