For electrophysiological assessment of visual function, a head mounted stereo display (eg virtual reality goggles) for displaying a stimulus is used to generate a retinal or cortical response. In particular, a method for objective electrophysiological assessment of visual function of at least one eye of a subject includes presenting a visual stimulus to at least one eye of the subject, recording at least one of a retinal response and a cortical response generated as a result of the presenting, analyzing said response and, as a result of said analysing, forming a map of the visual function of the at least one eye of the subject. The invention also relates to a system for such electrophysiological assessment.
