The Diopsys® NOVA-LX Vision Testing System is a part of the Diopsys® NOVA-VEP 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. By using VEP, the device provides quantitative information to support the interpretation and management of eye and vision deficits, and reports and documents the results of practitioner intervention for tracking patients’ response. It is easy to use, non-invasive, and provides a quick qualitative analysis of the VEP waveform and easy quantitative analysis of the amplitude (strength) and latency (speed) values.
The Diopsys® NOVA-LX also helps provide objective data to aid the physician in the detection of vision abnormalities that are often subtle and difficult to detect since no verbal response or “button pushing” is required from the patient, enabling testing of preverbal children, infants, and patients with communication difficulties.

The Diopsys® NOVA-LX is an easy-to-follow, fixed protocol VEP module that automatically guides the technician through the procedure. The protocol uses both low contrast and high contrast patterns to indicate the health of the magnocellular and parvocellular pathways. Clinicians may quickly view color-coded VEP results to enhance medical decision making and treatment planning.
Eye care specialists may test children six months of age and older, patients with a degenerative process such as glaucoma or multiple sclerosis (MS), or patients following a neurological event like traumatic brain injury (TBI) or stroke in order to help the clinician detect visual deficits such as optic nerve disorders, amblyopia, and other neuro-visual disorders.
