Electroretinography (ERG) Testing for Pets in Plano, TX
Electroretinography (ERG) is a non-invasive diagnostic test that measures the electrical activity of the retina—the light-sensitive layer at the back of the eye. At Animal Eye Specialists in Plano, we use ERG to evaluate retinal function in pets who may have vision loss or are preparing for cataract surgery.
When Is ERG Recommended?
ERG is commonly recommended if a pet has unexplained vision changes or if cataracts prevent a clear view of the retina. It helps our veterinary ophthalmologists determine whether the retina is functioning properly, even if the internal eye structures are not visible through examination alone.

How the Procedure Works
During the ERG, your pet is given light sedation for comfort. A contact lens electrode is placed on the eye, and flashes of light stimulate the retina. The equipment records the retina’s electrical responses, allowing us to analyze its function in real time. The procedure is painless and typically takes under an hour.
