Abstract: The invention relates to a method and system for determining the topography for reaction signals of an eye. The reaction signals of cyclic luminous excitations are simultaneously measured on partial surfaces of the retina by using, for each partial surface, another integer number of oscillations in a predetermined time segment. These oscillations are derived from a clock rate. In the time segment, a smaller number of oscillations occur by prolonging a clock pulse by an appointed interval, and a greater number of oscillations occur by shortening the clock pulse by an appointed interval. The cumulative signal recorded on the patient contains the sum of the reaction signals and is digitized in an amplified and filtered manner with the clock pulse for generating the oscillations. The reaction signals of the individual partial surfaces are recovered by cyclic summation.

Abstract: The purpose of the invention is to determine the topography of retinal reactions with high effectiveness and great certainty. In accordance with the invention, the problem is solved by generating a light-emitting image consisting of surface segments on a surface placed before the eye, and using complete extended m sequences, to brighten and darken the surface segments in each time interval. From the eye reaction signal, with the aid of the cross-correlation function, the reaction functions of the segments are calculated in each time interval, and the quality of the results is evaluated by forming some functions for each time interval. Only reaction signals evaluated as good are added up for the total result. The reaction signal of the eye is monitored for staying within limit values, and when errors are recognized, the m sequences are set back by a number of steps which can be preset, recognized errors in the reaction signal are replaced by the repetition.
