An electrophysiological follow-up study on acquired unilateral nyctalopia

Unilateral diaphragmatic paralysis: an electrophysiological study.

An electrophysiological study was carried out on four patients with unilateral diaphragmatic paralysis. Whereas neurogenic involvement of the paralysed hemidiaphragm was roughly similar in all cases, neurogenic patterns could be detected in the normally moving contralateral hemidiaphragm in three cases, and the degree of involvement could be correlated with the respiratory state of the patients...

Do Optic Disc Drusen Cause Unilateral Nyctalopia?

This is a case report of a patient with unilateral nyctalopia in whom ipsilateral optic disc drusen were the only finding despite extensive investigation.

Electrophysiological findings in persons with nyctalopia.

INTRODUCTION Ophthalmologists are occasionally confronted with an individual presenting with nyctalopia (i.e., a relatively greater difficulty seeing at night). When there is no accompanying abnormality seen in the fundus, visual electrophysiology becomes useful as an objective means of assessing rod (scotopic) photoreceptor function or pathway defects. MATERIALS AND METHODS A retrospective s...

Thalidomide neuropathy: a clinical electrophysiological, and histological follow-up study.

An electrophysiological follow up of patients with n-hexane polyneuropathy.

Electroneurographic (ENeG) and evoked potential (EP) studies were regularly performed on 11 printing workers with n-hexane polyneuropathy after cessation of exposure. At the initial examination, the ENeG studies simulated a demyelinative process. Further slowing of nerve conduction velocity, or further decreasing of action potential amplitude, or both in the follow up ENeG study were found in a...
