How Does Electroretinography (ERG) Help Detect Retinal Diseases Earlier?

Early detection is one of the most powerful tools we have in the fight against vision loss. At Your Eye Doctor P.C., we’re proud to offer in-office Electroretinography (ERG); a technology that’s not new to eye care, but has become significantly more accessible and efficient for everyday clinical use.
 

What Is Electroretinography (ERG)?

Electroretinography is a non-invasive test that measures the electrical responses of the retina. When your eyes are exposed to flashes of light, the retina's photoreceptor cells (rods and cones) generate electrical signals. The ERG test records these signals, allowing your eye doctor to evaluate how well your retina is functioning.
 

A Convenient Tool for Early Detection

Although ERG has been used in advanced eye care settings for years, the latest in-office ERG devices make it easier than ever to bring this technology directly to patients. This test can be done comfortably and efficiently during a routine eye exams.
 

Detecting Diabetic Retinopathy Early

ERG is especially useful for identifying diabetic retinopathy before traditional clinical signs appear. By evaluating retinal cell function, the ERG can detect changes in retinal health at a much earlier stage - sometimes before visible damage occurs. This allows for earlier intervention, better management of diabetes-related vision complications, and improved outcomes.
 

Diagnosing Genetic and Complex Retinal Disorders

In addition to diabetic retinopathy, ERG is invaluable for diagnosing genetic retinal diseases, such as retinitis pigmentosa and other inherited retinal conditions. These diseases often involve specific retinal cells, and ERG helps pinpoint the affected areas early in their progression.
 

Additionally, ERG provides a deeper, more functional view of the retina, making it a useful diagnostic aid in evaluating more complex eye diseases. It can enhance our understanding of conditions such as:
 

• Macular degeneration - by detecting functional deficits before they become anatomically visible
• Glaucoma - by assessing inner retinal function and identifying subtle retinal changes
• Other retinal dystrophies - by distinguishing between various types of retinal cell dysfunction
