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. 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. Diopsys® NOVA-TR Designed to allow the user to customize the stimulus to the patient and pathology, including the pattern, pattern size and contrast level. DiopsysHeader The Diopsys® NOVA-ERG Vision Testing System is an office-based pattern electroretinography (ERG) module – a part of the Diopsys® NOVA suite of tests. Pattern electroretinography can help doctors gain objective, functional information about the performance of the inner retinal cells of the eye, especially in the macula. 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-ERG conforms to the standards of the International Society for Clinical Electrophysiology of Vision (ISCEV) Protocols Concentric Stimulus FieldsERGProtocol Information gathered is intended to be used to aid in the diagnosis and care of diseases that affect the retina in specific topographic patterns, i.e., Age Related Macular Degeneration (AMD), Diabetes Macular Edema (CME) and Toxic Maculopathies (e.g. Plaquenil Maculopathy). These types of diseases usually have an expected pattern of macular deterioration, affecting the central or paracentral area of the macula. The NOVA-ERG Concentric Stimulus Fields test utilizes two different degrees of stimulus presented as concentric circles with contrast reversing patterns. Contrast Sensitivity Designed to provide data to aid in the diagnosis and care of diseases that affect the retina in a diffuse pattern like Chronic Open Angle Glaucoma (COAG) and Diabetic Retinopathy (DR). Since there is typically no specific topographic pattern of damage, the information collected using this protocol may help in detecting the depth of the macular dysfunction. The NOVA-ERG Contrast Sensitivity test utilizes a full screen stimulus with two different contrast levels to give an objective, functional response of the vision system at the retina. User-Defined Designed to allow the user to manually customize the stimulus to the patient and pathology, inluding the pattern, pattern size and contrast level. The NOVA-ERG is designed to provide data to the doctor to help detect cellular dysfunction that can precede evident structural defects, thereby contributing to earlier detection for more specific and timely management of diseases that impair macula and ganglion cells.
