Dural arteriovenous fistula and spontaneous choroidal detachment: new cause of an old disease.

A case is presented in which bilateral spontaneous choroidal detachments appear to be the direce result of bilateral dural arteriovenous fistula of the cavernous sinus region. Rapid resolution of the clinical signs followed bilateral orbital decompression via the transfrontal approach. Similarities in clinical presentation of both entities are reviewed and a premise for their cause-and-effect relationship elaborated. A literature search for similar unrecognised cases is discussed. The paper suggests that this association may be more frequent than published reports would imply.

Blue-domed cyst with optic nerve compression.

A patient presenting with persistent headache of vascular quality and an intermittently progressive chiasmal syndrome had a blue-domed haemorrhagic cyst beneath the right optic nerve and underwent surgical drainage with good results. As prompt surgical intervention may proivde significant return of visual function, detailed diagnostic evaluation of similar cases is recommended.

Amaurosis fugax from disease of the external carotid artery.

Three patients with proved internal carotid artery occlusion and diseased external carotid artery or common carotid artery had amaurosis fugax. Evidence for retinal embolization through external carotid collaterals is retinal emboli and infarction after carotid artery manipulation, amaurosis during external carotid angiography, and relief of amaurosis by endarterectomy of this vessel. The abundance of external carotid collaterals, their size, and natural incidence are discussed. Reports clinically support embolization to the central retinal artery and ophthalmic artery through these collaterals.

Smith-Lemli-Opitz syndrome: neuropathological and ophthalmological observations.

The case of a three-year-old boy with the Smith-Lemli-Opitz syndrome is reported. In addition to the constellation of skeletal and genital anomalies classically described in this syndrome, this patient had spontaneous opsoclonus-like eye movements, strabismus, lack of visual following responses and of opticokinetic reflexes. At autopsy the cerebellar vermis was found to be absent. There were retinal hemangiomas. Microscopical examinations showed loss of Purkinje cells and extensive neuronal degeneration within dentate nuclei, associated with patchy demyelination of cerebellar peduncles and central white matter. These findings may contribute to the explanation of the pathophysiology of opsoclonus and some of the neuro-ophthalmological findings.

Embolic posterior cerebral artery occlusion secondary to spondylitic vertebral artery compression. Case report.

The authors report a case of isolated homonymous hemianopsia secondary to embolic occlusion of the posterior cerebral artery. The cause of embolism was demonstrated to be spondylitic vertebral artery compression. The importance of arteriography is emphasized since the clinical syndrome may be nonspecific and myelographic or plain x-ray changes may be minimal. Surgical therapy is also discussed.

A fatal case of sun exposure in a multiple sclerosis patient.

A 35-year-old woman with a long standing history of relapsing-remitting multiple sclerosis became physically incapacitated by heat-induced muscle weakness while sunbathing and suffered fatal sun exposure. These deleterious effects of increased core temperature on the neurological symptoms have been documented for a half century. Elevation of the patient's core temperature may lead to either transient or permanent neurologic symptoms and signs that predispose to considerable morbidity and mortality.
