As in the subject - do you know any comercial systems for computer-based campimetry/perimetry, where light stimuli are displayed on the flat computer screen? I know only common perimeters based on the hemispherical surface stimuli presentation, such as Humphrey Field Analyser or Medmont M700. I'm also familiar with the software for psychophysics listed at http://www.hans.strasburger.de/psy_soft.html.
