•New software application with which to process mfVEP signal latency.•Several important parameters can be configured before starting analysis.•Signal display comparing different tests.•Detects which zone of the eye is most affected.•Achieves high latency measurement accuracy.
BackgroundThis paper describes a new non-commercial software application (mfVEP2) developed to process multifocal visual-evoked-potential (mfVEP) signals in latency (monocular and interocular) progression studies.MethodThe software performs analysis by cross-correlating signals from the same patients. The criteria applied by the software include best channels, signal window, cross-correlation limits and signal-to-noise ratio (SNR). Software features include signal display comparing different tests and groups of sectors (quadrants, rings and hemispheres).ResultsThe software׳s performance and capabilities are demonstrated on the results obtained from a patient with acute optic neuritis who underwent 9 follow-up mfVEP tests. Numerical values and graphics are presented and discussed for this case.ConclusionsThe authors present a software application used to study progression in mfVEP signals. It is also useful in research projects designed to improve mfVEP techniques. This software makes it easier for users to manage the signals and allows them to choose various ways of selecting signals and representing results.
