How the RETeval ERG Device Detects Vision Problems Before You Notice Symptoms

When it comes to eye health, early detection is key. Many serious eye conditions can begin developing long before you notice any changes in your vision. At Texas State Optical, we are proud to offer advanced diagnostic technology like the RETeval ERG device to help identify hidden problems within the eye.
 

What Is the RETeval ERG Device?

The RETeval device is a state-of-the-art tool that evaluates how well the retina and optic nerve are functioning. Rather than relying solely on visual acuity tests or patient-reported symptoms, this device uses non-invasive sensors placed near the eye to record the electrical signals generated in response to light stimuli. These signals provide valuable insight into the health of your retina and the visual pathways that connect your eyes to your brain.
 

Why Early Detection Matters

Many eye diseases develop silently. Conditions like diabetic retinopathy, glaucoma, and certain inherited retinal disorders can begin to impair visual function before noticeable vision loss occurs. The RETeval system helps detect early functional changes in the eye, giving your optometrist a deeper understanding of how your visual system is performing.

By measuring electrical activity in response to light flashes, your eye doctor can identify signs of stress or dysfunction in the retina and optic nerve. This makes it possible to begin treatment or monitoring strategies early - often before permanent damage occurs.
 

Comfortable, Quick, and Non-Invasive

One of the benefits of the RETeval ERG assessment is how simple and patient-friendly the process is. There are no eye drops or complex preparations required. The test involves placing small adhesive sensors on the skin around the eyes and exposing the eye to controlled flashes of light. The entire process is quick, painless, and can be performed as part of a regular eye exam.
 

A Smarter Way to Monitor Eye Health

For patients with diabetes, a family history of retinal disease, or those at risk for glaucoma, RETeval assessments offer a proactive approach to eye care. By tracking the electrical responses of the eye over time, your optometrist can monitor changes more precisely and adjust treatment plans accordingly.
