title: Multivariate analysis of visual evoked response.
abstract: The visual potentials evoked by flash are analyzed in healthy subjects in cases of retinal detachment, of optic nerve lesions, and of amblyopia by means of different statistical methods: 1. Analysis of the various features of the response, evaluated separately 2. Analysis of the interdependence between the measures of the various features The first method supplies information on the differences in 'size' of the curves in the various samples, the second method reveals differences of 'shape'. The second method has proved to be able to distinguish both normal conditions from pathologic impairment of optic structures and the different sites of the lesions.
