Electrophysiological Test Unit for quantifying the response to visual stimulation by measuring the Visual Evoked Potential.

The Visionsearch1 System consists of specialist software and the supporting computer and peripherals. The System displays multifocal visual patterns to evoke response in the retina which are transmitted to the visual cortex. The System then detects responses in the visual cortex using specific, validated third party EEG electrodes and biological amplifier. After analyzing the EEG, the System displays the electrical response from each segment of the retina. It also allows the user to compare the response time between eyes and compare an individual's measurements to those from a set of data that the user has compiled as reference.
