Diopsys® NOVA Vision Test System


As innovations in technology continue to transform the field of eye care, Eye Doctors of Washington is proud to offer the very latest in eye disease management. To discover  vision-related diseases in their earliest stages, we utilize the Diopsys® NOVA Vision Testing System. Through this state-of-the-art advancement in electrophysiological technology, we can effectively detect, diagnose, and monitor progress of treatment for conditions like glaucoma and macular degeneration at their earliest stages.

Our team makes use of both the VEP (Visual Evoked Potential) and ERG (Pattern Electroretinography) protocols to conduct objective, office-based vision testing. Before the process can begin, sensors are placed on the patient’s head similar to an electrocardiogram or EKG. With such a streamlined process, the Diopsys® NOVA technology provides the following advantages:

  • No need for the patient to verbally respond or push any buttons
  • Comfortable and relatively fast test
  • Easy-to-understand reports for the most accurate physician interpretation
  • Can help diagnose disorders as well as monitor treatment progress

The VEP and ERG tests each measure a specific area of the eye to thoroughly assess the function of the visual system.

Diopsys® NOVA-VEP (Visual Evoked Potential)

The Diopsys® NOVA-VEP measures the activity of the entire visual pathway. Results from this test can determine how well the entire visual system is functioning. This test can be performed on patients as early as six months or older to detect vision or optic nerve disorders. The VEP can also be used for patients who have developed neuro-visual problems following a traumatic brain injury or stroke. It can help determine if the optic nerve function is healthy or abnormal, as seen in multiple sclerosis and glaucoma.

Diopsys® NOVA-ERG (Pattern Electroretinography)

With the Diopsys® NOVA-ERG system, our team can determine the patient’s retinal function, which allows them to identify potential disorders. When used along with other diagnostic tests, like the VEP, this can help differentiate between a retinal and optic nerve disorder. The ERG can help detect these signs at a cellular level for earlier detection and a more timely treatment.

Considering the fact that visual diseases may develop differently, both the VEP and ERG tests are customized to the patient to fully understand their visual health. The entire process takes around 10 minutes, after which time we have instant access to the test results. The Diopsys® NOVA testing systems has proven to be an invaluable addition to our practice.
