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. The Diopsys^® NOVA-VEP Vision Testing System is available in both a Fixed Protocol with Multi-Contrast  Stimuli and User-Defined  Protocol configuration. 

The Diopsys^® NOVA-LX  is an easy-to-follow, fixed protocol VEP module that automatically guides the technician through the procedure, and takes 38-53 seconds per eye, or approximately 5 minutes from set-up to results. The procedure 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.

The Diopsys^® NOVA-TR objectively measures the neurological responses of the entire visual pathway using multiple testing options. It is easy to use, non-invasive, and testing times are flexible and depend upon the customized settings designated by the clinician. Patented technology for stimulus generation allows the clinician to manually customize the pattern reversal and frequency of checkerboard, horizontal, vertical, or sinusoidal patterns to the patient and pathology. The Diopsys^® NOVA-TR allows clinicians to specify therapy types and duration of treatment (i.e., patching, lens, surgery) to document the results of physician intervention, and support medical decision-making.
