What is Diopsys technology?

Diopsys visual electrophysiology vision tests allow Dr. Whitson and the team at Whitson Vision to have access to the most comprehensive information about your eyes and vision. Electroretinography (ERG) and visual evoked potential (VEP) diagnostic test results effectively monitor your vision and assist your physician in determining a customized treatment plan for your specific vision conditions.

The tests are painless and noninvasive to keep you comfortable during your extensive eye exam. Both the ERG and VEP are important vision tests that provide invaluable information about your eyes.

What is the Diopsys ERG vision test?

The Diopsys ERG test measures the function of your retina. Your retina is the area at the back of your eye that refracts, or bends, light so you can see objects clearly. The ERG test uses visual stimuli from a computer screen to elicit an electrical response from your retina. It’s essentially like an EKG for your eyes.

What is the Diopsys VEP vision test?

Another painless, noninvasive vision test using the latest technology is the Diopsys VEP vision test. The VEP test measures the overall function of your eyes. Like ERG, VEP also uses stimuli from a computer to elicit an electrical response from your retina. This electrical energy goes to your visual cortex, which is the part of your brain that processes images.

The Diopsys VEP vision technology records the electrical signal that goes to your visual cortex and records the information for your physician to analyze.

Is Diopsys technology a replacement for other vision tests?

No, it’s not. You may still need a visual field test and other routine tests during your eye exam. However, the Diopsys system provides yet another layer of information so that your physcian can prescribe the most accurate and comprehensive course of treatment for your particular vision problems.

What can I expect during Diopsys vision testing?

Both the ERG and VEP tests use three small sensors that attach to your face or head. During the tests, you sit in front of a computer monitor and look at the center of the screen. As the screen displays visual patterns, the computer records your visual response and compiles the data for your physician.
