Computed tomography has revolutionized the diagnosis of ophthalmologic and neuro-ophthalmologic disease. High resolution CT with thin-section techniques has made available the depiction of finer anatomic orbital detail and permits radiologic detection of more subtle lesions than was previously available. ⋯ A segment of the superior ophthalmic vein was identified in 18 of 64 orbits examined by CT. Virtually the entire superior ophthalmic vein was identified in three orbits.
