The concept is as follows: Each visual field location is stimulated with a Stimulus Sequence that is Uncorrelated to the sequences used for the other locations. All visual field locations are stimulated in parallel with their individual stimulus sequence. The retinal or cortical activity, which is a mixture of the responses from all visual field locations, is recorded with usual electroretinographic or visual evoked potential methods, respectively. Due to the independence of the stimulus sequences, the responses for each visual field location can be extracted using mathematical algorithms. Mutifocal techniques, in particular the multifocal ERG, are used in the Diagnosis of Ophthalmological diseases. |
