Diopsys

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. Our 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.

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.

Concentric Stimulus Fields

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).

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).
