Auditory 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 کاملCentrifugal Optic Nerve Responses Evoked by Auditory and Somatic Stimulation.
The evidence for the efferent control of receptor events has recently been repeatedly challenged. The present experiments were undertaken to provide a simple 'demonstration of the existence of such a mechanism. Clicks were presented to unanesthetized cats and bipolar recordings made of potential changes evoked in the optic nerve' and tract with implants of small (300 I.t spaced about 0.2 mm) el...

متن کاملPosition, size and luminosity of phosphenes generated by direct optic nerve stimulation
Pulses of low intensity current, delivered through a cuff electrode chronically implanted around the optic nerve of a blind retinitis pigmentosa patient generate visual sensations. These phosphenes are obtained at lower thresholds for a train of stimuli than for single pulses, which suggests the existence of a spatial and temporal integrating mechanism. The perceptions are much smaller than tho...
متن کاملMicrovascular Decompression of the Optic Nerve for Paroxysmal Phosphenes and Visual Field Deficit.
BACKGROUND Microvascular decompression surgery is standard neurosurgical practice for treating trigeminal neuralgia and hemifacial spasm. Most other cranial nerves have been decompressed for paroxysmal intermittent hyperactivity of the affected cranial nerve or in very long-standing compressions to treat cranial nerve hypofunctioning. CASE DESCRIPTION We describe a case of intermittent paroxy...
