摘要:

Surgical exploration and biopsy confirmed the clinical diagnosis of bilateral optic nerve sheath meningiomas in a 27-year-old male patient with radiologic findings of calcifications of the intraorbital portions of the optic nerves. Plain orbital x-rays revealed ring calcifications and a CT scan disclosed the true extent of these calcifications, which were found to extend bilaterally along the nerves from the globes to the optic foramina. Coronal CT scan images revealed that the ring of calcification extended almost unbroken for the entire intraorbital length of the optic nerves. These optic nerve sheath calcifications represented calcified meningiomas.

摘要:

This article reports three cases of visual failure of presumably ischemic etiology, after aneurysm surgery; the first case occurring 7 months after clipping and gauze wrapping of a 4-mm anterior communicating artery aneurysm; the second case occurring 8 months after gauze wrapping of a partially intracavernous 10-mm internal carotid artery aneurysm which projected into the right optic foramen; and the third case occurring 11 months after ligation, clipping, and gauze wrapping of an 8-mm internal carotid-posterior communicating artery aneurysm.

摘要:

A 72-year-old, white male presented with sudden, painless loss of vision bilaterally associated with optic disc swelling. His visual loss occurred within 24 hours of receiving multiple beestings. Clinical examination revealed papillitis. Optic neuritis associated with beestings is a rare complication which is not understood fully.

摘要:

All patients between 1977 and 1982 who presented with unilateral exophthalmos were evaluated with contact B-scan ultrasonography. Of these, eight patients were diagnosed as having retro-orbital or orbital arteriovenous anomalies (two carotidcavernous sinus fistulas, four dural arteriovenous malformations, and two orbital arteriovenous malformations). On B-scan ultrasound, all of these patients demonstrated a dilated superior ophthalmic vein. None of the other patients with unilateral proptosis demonstrated this finding. With recent advances in treatment of these conditions, early diagnosis becomes increasingly important. Contact B-scan ultrasonography (which is widely available, convenient, and expedient) can be used for early diagnosis of arteriovenous anomalies in the orbit and cavernous sinus areas. Other ultrasonic techniques such as A-scan, standardized A-scan, or immersion B-scan, are equally reliable in the recognition of a dilated superior orbital vein. In the authors' opinion, however, these are less convenient, more time consuming, and require more expertise for similar results.

摘要:

A 35-year-old woman with an isolated, transient sixth cranial nerve palsy was found to have a positive fluorescent antinuclear antibody test with a pattern and titer most consistent with systemic lupus erythematosus. Mild anemia and leukopenia were also present. Over 2 months she improved without treatment. Nervous system disease in systemic lupus erythematosus and the unusual nature of presentation in this case are discussed.

摘要:

An 80-year-old man developed right herpes zoster ophthalmicus complicated by contralateral hemiparesis after right cataract extraction. Although herpes zoster ophthalmicus is a frequent occurrence among the elderly, the association with contralateral hemiparesis is probably overlooked by many ophthalmologists. A review of the literature has been made to outline the etiology of this problem and to make diagnosis more likely. The varicella virus probably spreads in a retrograde fashion from the gasserian ganglion toward the cavernous sinus to involve cranial nerves 3, 4, or 6. Involvement of the ipsilateral carotid arterial system by the progressive inflammatory reaction can result in the contralateral hemiparesis. Standard therapy includes topical steroids and topical antibiotics for the ocular and surface lesions. The efficacy of systemic steroids to minimize the hemiparesis is still in question.

摘要:

A 34-year-old man had both periodic alternating nystagmus and periodic alternating skew deviation. Neurologic examination and cranial computed tomography supported the diagnosis of cerebellar degeneration. Pathophysiologic mechanisms of these motility disturbances are discussed briefly. To our knowledge these two unusual eye movement abnormalities have not been reported previously in the same patient.
