Feb 13, 2026 · The electroretinogram (ERG) is a diagnostic test that measures the electrical activity of the retina in response to a light stimulus. The ERG arises from currents generated directly by retinal …

Electroretinography measures the electrical responses of various cell types in the retina, including the photoreceptors (rods and cones), inner retinal cells (bipolar and amacrine cells), and the ganglion …

Read about electroretinography (ERG), an eye test where electrodes placed on the cornea measure electrical responses to light to try to detect abnormal retinal function.

Apr 20, 2020 · What is electroretinography? An electroretinography (ERG) test, also known as an electroretinogram, measures the electrical response of the light-sensitive cells in your eyes. …

Electroretinography (ERG) is a highly specialized diagnostic test that evaluates the retina’s electrical responses to light stimuli. By analyzing these responses, an ERG test helps detect and …

Aug 5, 2024 · Electroretinography is a test to measure the electrical response of the eye's light-sensitive cells, called rods and cones. These cells are part of the retina (the back part of the eye).

The electroretinogram (ERG) is an examination that evaluates the function of the eye’s retinal cells. Patients’ eyes are stimulated with light and the resulting electrical activity from their retinal cells is …
