Multiple regression analysis of diagnostic predictors in optic nerve disease.
Demyelination is assumed to be the cause of the majority of cases of isolated optic neuritis. Because of the importance of establishing the presence of optic nerve dysfunction in patients suspected of having multiple sclerosis several new indices of optic nerve conduction have been reported including the visual evoked potential, the edge-light pupil cycle time, and the Pulfrich test. These meas...

متن کاملAuditory evoked phosphenes in optic nerve disease.
Five patients with optic neuropathy, four vascular and one demyelinating, are described who each complained of an unusual symptom. Bright flashes of light (phosphenes) occurred in the affected eyes and were evoked by sudden unexpected sounds. Movement of the eye alone did not reproduce the symptom. In all patients the phenomenon was sufficiently prominent to interfere with sleep and was the mai...
متن کاملVitreous fluorophotometry in optic nerve disease.
Posterior vitreous fluorophotometry measurements have been shown to be increased in patients with acute retrobulbar neuritis. We studied 12 patients who had optic neuropathy by posterior vitreous fluorophotometry, with and without correction for blood fluorescein concentration. Both uncorrected and corrected posterior vitreous measurements were increased in patients with inflammatory, obstructi...
متن کاملOptic nerve enlargement in Krabbe's disease.
We report imaging and gross pathologic findings from two cases of Krabbe disease in which there was marked enlargement of the intracranial optic nerves. Numerous globoid cells were observed in the optic nerves at autopsy in one case. Krabbe disease should be included in the differential diagnosis of children with enlargement of the optic nerves.
