with conventional methods including orbital arteriography, orbital venography, penumoorbitography and positive contrast orbitography, imaging of eyeball and orbit is not only difficult, invasive or expensive but also nonspecific in result. Ultrasonography provides safe, specific and reliable way to obtain image of eyeball and orbit. Fifty six ultrasonograms of 50 patients which were referred under the impression of various ophthalmic diseases were analyzed. 1. Sixteen cases were normal. 2. Ocular diseases were 26 cases and extraocular orbital diseases were 8 cases. 3. Among the ocular diseases, 9 foreign body cases, 6 retinal detachment cases, 5 vitreous hemorrhage 4. Among the extraocular orbital diseases, 5 pseoudotumor cases, 1 pseudolymphoma, 1 eyelid cyst case were diagnosed. 5. Ultrasonic findings were specific enough to differentiated from other diseases and well corresponded with clinical and pathological diagnosis. 6. It can be concluded that ultrasonography is one of the most reliable imaging method in ocular and extraocular orbital diseases.
