The Diopsys® Neuro Optic Vision Assessment Systems use a technology called Visual Evoked Potential (VEP) to evaluate a patient’s response to an external stimulus along the entire visual pathway from the lens of the eye to the visual cortex. By using VEP, the Diopsys® NOVA-VEP Systems provide objective, quantitative information on the function of the vision system to support the clinician in the interpretation and diagnosis of vision deficits. The Diopsys® NOVA-VEP Systems also offer objective measurements for tracking disease progression and patients’ response to clinicians’ treatment.
