Estimating the term…
This invention relates to the electrophysiological assessment of visual function using a head mounted stereo display (eg virtual reality goggles) for displaying a stimulus which is used to generate a retinal or cortical response. In particular, the invention relates to a method for objective electrophysiological assessment of visual function of at least one eye of a patient, which method comprises presenting a visual stimulus to at least one eye of the patient, recording at least one resultant response, selected from the group consisting of a retinal response and a cortical response, generated as a result of the presenting; analysing said response; and as a result of said analysing, forming a map of the visual function of the at least one eye of the patient. The invention also relates to as system for such electrophysiological assessment.
A method for objective electrophysiological assessment of visual function, when method comprises placing a head-mounted stereo display for presenting a stimulus, on the head of a patient, placing electrodes on the scalp or in contact with the eye of said patient, connecting said head-mounted stereo display to a computer which generates an algorithm for driving said stimulus;
A system for electrophysiological assessment of visual function of at least one eye of a patient, comprising a head-mounted stereo display for presenting a stimulus to at least one eye of the patient;
A method for analysing at least one multifocal visual evoked potential recording from any mode of multifocal stimulation comprising scaling output from computer software according to overall spontaneous brain activity levels (ie. electroencephalogram levels) of a subject during the recording in order to minimise inter-subject variability.
