[Devic's neuromyelitis optica: diagnosis after 10 years of bilateral severe relapsing optic neuritis].

Introduction: Neuromyelitis optica, also known as Devic's disease, is a severe idiopathic inflammatory demyelinating disease of the central nervous system that preferentially affects the optic nerve and spinal cord. Neuromyelitis optica has long been thought of as a variant of multiple sclerosis; however, clinical, laboratory, immunological, and pathological characteristics that distinguish it from multiple sclerosis have now been recognized.

Case Report: A young man presented isolated severe bilateral relapsing optic neuritis.

[Multifocal ERG using ERG-jet and Gold Foil electrodes in normal subjects: comparison and reproducibility].

Purpose: To compare multifocal electroretinogram (mfERG) amplitudes with the Gold Foil electrode and ERG-jet electrode. To study mfERG amplitude changes between two successive records (intraindividual reproducibility).

Methods: The right eye of 27 normal subjects was examined.
