Electroretinography (ERG) is a non-invasive eye test that measures the retina’s electrical response to light. The retina is the light-sensitive tissue at the back of the eye, and its function is vital for clear, healthy vision.

Why ERG Matters for Your Eye Health

Many eye diseases begin silently at a cellular level—long before symptoms appear. ERG allows for early detection of retinal dysfunction, enabling timely diagnosis and more effective treatment.

Conditions ERG Helps Detect and Monitor:

Diabetic Retinopathy
Glaucoma
Retinitis Pigmentosa and other inherited retinal diseases
Macular Degeneration
High Myopia (short-sightedness)

With early intervention, we can better preserve your vision and monitor long-term retinal health.

ERG and Myopia Control: Detecting Complex Cases Early

While myopia is common, high or rapidly progressing myopia, especially in children, can sometimes be linked to syndromic or genetic conditions. Recent research highlights ERG as a key tool in detecting these subtle retinal abnormalities.

Our optometrists use ERG to identify syndromic myopia, ensuring accurate diagnosis, appropriate referrals, and personalised management plans—far beyond standard vision correction.

What to Expect During an ERG Test

Quick and painless, typically 20–30 minutes
Electrodes placed on or around the eye
You’ll look at flashing lights or visual patterns
Retinal responses are recorded and analysed by our experts
