Diopsys® is an advanced diagnostic tool that is painless, safe, and non-invasive way for our doctors to objectively measure the functionality of your entire vision system. It also enables our doctors to examine the entire visual pathway for visual and neuro-visual disorders.
A Diopsys® ERG vision test measures the function of your retina – the light-sensitive layer at the back of your eye.
When light from an image enters your eye, it is turned into electrical energy by cells in the retina. Pattern ERG, or electroretinography, uses visual stimuli from a computer screen in different patterns and contrasts to elicit that electrical response. The electrical energy created is measured by the Diopsys® ERG vision test, and used to create a report for your doctor. It is similar to an EKG, but for your eyes
VEP, or Visual Evoked Potential, uses visual stimuli from a computer screen in different patterns and contrasts to elicit the electrical response from your retina. The electrical energy is then sent to your visual cortex where the VEP vision test records the signal and creates a report for your doctor. It is similar to an EKG, but for your entire vision system.
