The invention relates to a method and arrangement for optically stimulating the visual system according to the requirements of the static perimetry and for objectively evaluating adequate stimulus-related electrophysical and/or magnetophysical quantities. Physiologically adequate luminous excitations with defined luminous 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 (1), and the excitation responses are amplified and digitized by a device (3), which preferably comprises an ERG/EEG measuring system and an A/D converter. To this end, the device (3), for the purpose of evaluating, and the light sources, for the purpose of controlling, are connected to a controlling means (2), preferably to a PC provided with evaluation and control software.
