[Objective evaluation of contrast sensitivity by visual evoked potentials].
The Contrast Sensitivity Function (CSF) is ore often determined by a psychophysical method. To obtain an objective measurement of CSF, we used steady-state Visual Evoked Potential (VEP) with a real time technique. Contrast levels are higher for thresholds determined by VEP technique. Correlation between psychophysical and objective methods is quite good.
