Ophthalmology Test Using Visual Evoked Potential

Diopsys NOVA-DT VEP Vision Testing System

The Diopsys Neuro Optic Vision Assessment-Diagnostic & Tracking VEP Vision Testing System (NOVA-DT) has been developed for ophthalmologists to objectively measure the neurological responses of the entire visual pathway. It is easy to use, non-invasive, and typically requires approximately five to twenty minutes to test both eyes.

The NOVA-DT System uses 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 of the brain. By using VEP, the NOVA-DT is able to identify optical/neural abnormalities related to vision that an Ophthalmologist might not otherwise detect. The NOVA-DT allows the clinician to objectively document a patient’s response to therapy.

Features & Specifications:

Patented technology for stimulus generation allows user to designate pattern reversal and frequency of checkerboard, horizontal, vertical, or sinusoidal patterns.
Algorithms embedded in the NOVA-DT software allow immediate and objective data analysis, and on-site test results.
Randomized music and animated characters are available to maintain child’s fixation.
Synchronized data collection provides quick, objective analysis of neurological response to stimuli. Data may be presented for diagnosis, or serially for “response to therapy”.
User may indicate specific therapy and time of treatment (i.e., patching, lens, surgery) to objectively track efficacy.
Utilizes three, disposable silver chloride electrodes/test.
Mobile point of care wheeled cart.
Menu driven flat panel operator monitor.
17 inch flat panel stimulus monitor.
Bluetooth^® color printer for report generation.
