Title:
視覚系を光学的に刺激するための方法および装置
Document Type and Number:
Japanese Patent JP2004517658
Kind Code:
A
Abstract:
A method and device for optically stimulating the visual system during static perimetry and for objectively evaluating adequate stimulus-related electrophysiological and/or magnetophysiological quantities. Light stimuli with defined parameters derived from a predetermined correlation function and from the known intensity dependence of the excitation response amplitude are presented to the observer. The excitation responses contained in the ERG and/or in the EEG/MEG are detected and processed. These excitation responses are used to determine and topographically evaluate the local sensitivity of the visual system. In one embodiment, the light sources are fixed inside a perimeter, and the excitation responses are amplified and digitized by a device, which preferably comprises an ERG/EEG measuring system and an A/D converter. To this end, the device, for the purpose of evaluating, and the light sources, for the purpose of controlling, are connected to a controlling means, preferably to a PC provided with evaluation and control software.
