Diopsys® VEP tests 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. Diopsys offers two VEP modules – Multi-Contrast(LX) and User-Defined.

      • Both objective and functional test results, no verbal response or “button pushing” required.
      • Color-coded reports for rapid, intuitive report interpretation.
      • Enhanced treatment tracking and patient management with quantitative data.
      • All Diopsys VEP tests conform to the standards of the International Society for Clinical Electrophysiology of Vision (ISCEV).


Diopsys® VEP – Multi-Contrast (LX)

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.

Diopsys® VEP – User-Defined

Designed to allow the user to customize the stimulus to the patient and pathology, including the pattern, pattern size and contrast level.

Diopsys NOVA-LX Report

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.
