The visual evoked response in hysterical amblyopia.

The visual evoked response in hysterical amblyopia.

Hysterical amblyopia is a term used to describe a syndrome in which reduction of visual acuity accompanied by contraction of the visual fields occurs in the absence of any organic lesion. This syndrome has been the subject of many reports (Eames, I 947; Yasuna, 1951; Schlaegel and Quilala, 1955; Krill, I967), but no conclusive diagnostic test has yet been established. Spiralling of the visual f...

Multifocal visual evoked potentials in amblyopia due to anisometropia

PURPOSE To investigate multifocal visual evoked potentials (mfVEP) of the amblyopic and fellow eye in amblyopia due to anisometropia. METHODS We recorded mfVEP in both eyes of 15 anisometropic amblyopic patients and 15 normal control subjects. The responses from the central 7.0 degrees arc of the visual field were measured, and changes in latency and amplitude were compared between the amblyo...

Visual Evoked Cortical Response in the Cat.

The cortical response of the cat to light fashes has been studied, the locus of greatest amplitude of response noted, and the conformation described. Recordings through the dura indicate that there is diminution of the response amplitude and reduction of localization caused by the dura. The effects of stimulus parameter changesy of application of strychnine locally, and of intravenous pentobarb...
