The Evolution of Objective, Functional Testing in Ophthalmic Practices

Posted by Diopsys, Inc. on September 22, 2018 at 3:29 PM

Diopsys Turns 20!


Twenty years ago, visual electrophysiology testing was not widely used in the eye care office, and its importance to routine clinical practice was poorly understood. Diopsys has changed all that.

The early experience with visual electrophysiology is hardly reflective of how this testing is used in modern eye care today, especially with the advent of smaller platforms and streamlined protocols. Even as new diagnostic technology has entered the eye care space, electrophysiology testing has gained a more prominent role in evaluating patients, precisely because no other testing modality can deliver both objective and functional information about the health of retinal cells. For eye care specialists, that kind of data is indispensable for deciding who to treat and how to treat.

“It's another tool in the toolbox,” said Mark Latina, MD, “We think we understand a lot of diseases, we think we know what we are doing, but this testing gives us an objective functional approach to patients, and that is a huge benefit.”

Light Induced Visual-response (LIV)


Light Induced Visual-response (LIV) measures the electrical responses of cells within the eye upon stimulation by a light source. Various stimuli can be used to target different cells within the visual pathway to gain objective information regarding their function, thus allowing clinicians to detect even subtle changes in cell health and viability. But what is the real value of LIV?

With objective, functional data, Light Induced Visual-response allows for tailored treatment and more precise disease management.

Diopsys, Inc: Our ERG and VEP History

Posted by Diopsys, Inc. on September 28, 2016 at 3:21 PM


Diopsys introduced its first visual evoked potential (VEP) device at the American Academy of Pediatrics meeting in 2004, and has been leading the visual electrophysiology space ever since. Our Research and Development program is very important to the success of our vision testing devices, and our customers have benefited from our continuous product expansions. In addition to all of the clinical research done in the last 16 years, we currently have 15 studies running at several prestigious institutions, such as:

  • Wills Eye Hospital
  • Doheny Eye Institute
  • New York Eye and Ear Infirmary
  • University of Pittsburgh Medical Center (UPMC)
  • UCSF Medical Center

Take a look at our brief history below to see where we came from, and where we're headed.
