Electrodiagnostic Tests in Eye Disease.
Basis of the Electroretinogram An electrical potential exists between the cornea and the fundus of the living eye. When the eye is illuminated by a flash of light a small potential is generated in addition to this corneofundal potential, which forms the ERG. This is analogous to the way in which the ECG is recorded above the steady skin potential. The final response is the sum of a number of co...
متن کاملComparison of electrodiagnostic criteria for primary demyelination in chronic polyneuropathy.
Three sets of electrodiagnostic criteria for establishing primary demyelination in chronic polyneuropathy are evaluated. Sensitivity is assessed in 70 patients with clinically established chronic inflammatory demyelinating polyradiculoneuropathy (CIDP). The criteria use different abnormal values, one adjusts for the effects of axonal loss, while another relies only on conduction velocity. Howev...
متن کاملAcute-onset chronic inflammatory demyelinating polyneuropathy: An electrodiagnostic study.
INTRODUCTION Acute-onset chronic inflammatory demyelinating polyneuropathy (A-CIDP) is an increasingly recognized CIDP subtype. Differentiating A-CIDP from Guillain-Barré syndrome (GBS) is challenging but important, because there are different treatment outcomes. METHODS We report 3 patients with A-CIDP who were initially diagnosed with severe GBS but were later confirmed to have CIDP based o...
متن کاملComparison of electrodiagnostic abnormalities and criteria in a cohort of patients with chronic inflammatory demyelinating polyneuropathy.
BACKGROUND Current electrodiagnostic criteria for chronic inflammatory demyelinating polyneuropathy (CIDP) are research oriented favoring specificity over sensitivity. Application of such criteria in clinical practice may miss the diagnosis in potentially treatable patients. OBJECTIVES To analyze the electrophysiologic abnormalities in a cohort of patients with clinically defined CIDP, to com...
متن کاملThe electrodiagnostic sensitivity of proximal lower extremity muscles in the diagnosis of L5 radiculopathy.
The aim of this study was to assess the electrodiagnostic (EDx) sensitivity of proximal lower extremity muscles, including tensor fascia lata (TFL) and gluteus medius (GMED), in the diagnosis of L5 radiculopathy.Eleven EDx recordings with L5 radiculopathy were collected. The motor unit action potentials were assessed for morphology, stability, and firing characteristics. A descriptive analysis ...
