The author examined 43 patients with various ophthalmic problems by using E.M.I. scanner 5005/7 from Oct. 77 to Sep. 78. The results which were analized by picture and pathology were obtained as follows; 1) The greaest number of cases were complaints of unilateral and bilateral proptosis. Eleven intraorbital tumors and one mucocele were detected in proptosis cases. 2) Among intraorbital tumors, pseudotumor was most frequently observed. 3) Intraocular tumors were found most frequently at superotemporal and inferotemporal area in the orbit. 4) An increase in absorption coefficient was observed after the use of contrast medium infusion in the case of tumors. On the other hand, no enhancement effect was shown in all cases of mucocele and intracranial hematomas. C.T. is a markedly useful examination, not only to investigate intraorbital space occupying lesions, but also to detect abnormalities of neuro-ophthalmological patients.

Weber-Christian disease (WCD) is a rare inflammatory disease of adipose tissue, which is characterized by painful cutaneous nodules and constitutional symptoms. Although any area of the body containing fat can be affected by WCD, the involvement of retrobulbar fat is uncommon and proptosis is a rare presenting manifestation. We report a case who presented with proptosis of the right eye which is accompanied by painful subcutaneous nodules, high fever and myalgia. Biopsies of retrobulbar tissue and suprapubic nodule showed lobular panniculitis with mixed cellular infiltration, mainly composed of histiocytes and lymphocytes. He responded well to high-dose glucocorticoid.

Leprosy is a chronic systemic disease with ocular complications including lagophthalmos, uveal diseases, and corneal diseases. Blindness may result unless appropriate treatment is done. The authors report the ocular leprosy with generalized systemic nodules associated with severe proptosis, corneal opacity and retinal pathology.

A case of traumatic delayed meningo-encephalocele suffered orbital fracture, but bony defects in frontal sinus had not been found on CT scanning. We treated the patient with surgery of intranasal endoscopy and repaired the skull base defect successfully during the first attempt. There was no recurrence in 10 months followed up. The leak site may not correlate with imaging in traumatic delayed meningo-encephalocele by comparing operative findings with the imaging estimate and endoscopy. Therefore, endoscopical approaching is effective in seeking and treatment.

Endoscopic sinus surgery is effective to nasal sinus mucocele with eye symptoms as main manifestation. It is very importment to raise the awareness of the disease and to prompt imaging examination. Three cases were reviewed. One mucocele was found in the frontal sinus ethmoid sinus,1 in the fronto-ethmoid sinus and 1 in the spheno-ethmoid sinus. All cases were preoperatively diagnosed by CT, MRI or intranasal endoscopy. Nasal sinus mucocele with eye symptoms as main manifestation should be early diagnosed. Endoscopic sinus surgery is a safe and effective method for the treatment of nasal sinus mucocele,and could be the primary choice for it. All cases were treated by nasal endoscopic sinus surgery. The majority of symptoms, such as exophthalmos, epiphora and diplopia, disappeared in all patients. However, vision recovery was observed only in some patients.

BACKGROUNDWith conventional imaging methods only the morphous of the visual nerve fiber bundles can be demonstrated, while the earlier period functional changes can not be demonstrated. We hypothesized that diffusion tensor imaging (DTI) would demonstrated the whole optic never fiber bundle and visual pathway and the earlier period functional changes. The purpose of the present study was to evaluate the application of DTI technique in the demonstration of the whole optic never fiber bundle and visual pathway, and the influence of orbital tumors on them.

METHODSGE 1.5 T signa HD MR System, and the software package DTV2 were adopted. The total 45 subjects were enrolled, including 15 volunteers and 30 patients. All patients had ocular proptosis from minor to major. Seven patients had visual acuity decrescence.

RESULTSThe nerve fiber bundles, e.g. optic chiasma, optic tract and optic radiation in posterior visual pathway were well demonstrated in all cases. Wherein, the intact whole visual pathway fiber bundles were clearly revealed in 10 volunteers and 17 patients, and optic nerve was not wholly revealed in the rest of the subjects. Shift of optic nerve caused by compression and partial deformation were seen in 7 patients with orbital tumor. In 6 of 7 patients, DTI displayed significant abscise and deformation of visual nerve. Chi-square test indicated significant correlation between visual acuity decrescence and DTI visual nerve non-display.

CONCLUSIONSVisual nerve fiber bundles and the whole visual pathway were visualized in most of patients with DTI. It might be an effective method of providing imaging evidence for visual nerve fiber earlier period functional changes, and laid a foundation for the study in other cranial nerves.

Osteoma is a slowly growing benign tumor which mainly grows on the mandible and in the paranasal sinuses of the craniofacial region. Embryological, inflammatory, and traumatic theories make up the etiological basis of osteoma, but is still unclear and yet to be studied. We can classify osteoma by morphology and pathology into eburnated, cancellous, and mixed type, of which eburnated type is relatively common. Most osteomas accompany no symptoms, so they are often discovered accidentally by a radiological examination. They never develop into a malignant form, so that periodic observation is sufficient enough for management, but when they grow and invade intraorbitally or intracranially and then compress clinically important structures, need a surgical management, because of possibility of diplopia, exophthalmos, epiphora, blindness due to optic atrophy, mucocele, brain abscess, meningitis. A 52-year-old man complaining of right eye pain, diplopia, and exophthalmos was diagnosed a 4.5x3.0x 2.0cm sized fronto-ethmoidal osteoma by means of a three dimensional computed tomography. We experienced a osteoma removal through bicoronal incision, and orbital reconstruction with both rib and calvarial bone graft, and received satisfying results after 1 year follow-up, thereby report this case with a short review of references.
