The Diopsys® NOVA-VEP Vision Testing System is a part of the Diopsys® NOVA suite of tests which use a technology called Visual Evoked Potential (VEP) to objectively measure the functional responses of the entire visual pathway from the anterior segment of the eye to the visual cortex. Using VEP test results can help improve sensitivity and specificity in diagnosing visual pathway disorders when used in conjunction with other diagnostic tests. The Diopsys® NOVA-VEP system comes equipped with two protocols – the Diopsys® NOVA-LX and Diopsys® NOVA-TR.
- No verbal response or “button pushing” required, providing objective results.
- Report contains quantitative information formatted to facilitate physician test interpretation and patient management.
- Documents the results of practitioner intervention for tracking patients’ response.
- The Diopsys® NOVA-VEP conforms to the standards of the International Society for Clinical Electrophysiology of Vision (ISCEV)
Created to provide doctors with an easy-to-follow, advanced protocol that guides the technician through the test procedure. The color-coded reports show results for low contrast tests, indicating the health of magnocellular pathways, and high contrast tests, indicating the health of parvocellular pathways.
Designed to allow the user to customize the stimulus to the patient and pathology, including the pattern, pattern size and contrast level.
Eye Care Specialists may test patients six months of age and older for vision and optic nerve disorders such as glaucoma, multiple sclerosis (MS), and amblyopia. Patients may also be tested to detect neuro-visual problems caused by traumatic brain injury (TBI) or stroke.
