Diopsys_Early Detection_Enhanced Patient Management.jpg

Do you diagnose and manage glaucoma,
diabetic retinopathy, or optic neuritis?1-3

As the world leader in modern visual electrophysiology, Diopsys, Inc. has done more than any other company to advance the use of electroretinography (ERG) and visual evoked potential (VEP) in the eye care practice. The company’s unique, patented technology provides eye care professionals with objective, functional information about the health of the vision system to aid in the early detection of vision disorders, and post-treatment tracking for enhanced patient management. Results from these tests are not just for rare diseases, but also for the management of more common disorders like glaucoma, diabetic retinopathy, optic neuritis, and retinal concerns obscured by media opacities.1-4

Three platforms. Complete visual electrophysiology suite.

We understand that not all eye care practices are the same. Therefore, we provide three unique platforms for our advanced suite of visual electrophysiology modules. The Diopsys® NOVA™ (cart), Diopsys® ARGOS™ (tabletop), and the Diopsys® RETINA PLUS™ (carry case) ERG and VEP Vision Testing Systems allow you to perform multiple visual electrophysiology tests right in your clinical practice. All with intuitive, clear test results that are color-coded based on documented reference ranges.

Diopsys® ERG (pattern electroretinography)

  • Measures performance of retinal ganglion cells
  • Helps identify “stressed” cells at a subclinical stage, when the cells have become dysfunctional but are still alive5

Diopsys® mfERG (multifocal electroretinography)

  • Helps recognize the first signs of drug-induced retinopathy
  • May indicate retinal dysfunction without structural abnormalities6-8

Diopsys® ffERG / Flicker (flicker electroretinography)

  • Indicates level of retinal function loss and recovery on patients with retinopathies9-10
  • Ability to measure the effect of retinopathies on vision through the presence of cataracts.4

Diopsys® VEP (visual evoked potential)

  • Provides objective information on the function of the entire vision system, from the anterior segment of the eye to the visual cortex

Learn how to integrate these exciting technologies into your daily practice.
