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 neurons in combination with contributions from retinal glia.

Electroretinography (ERG) is an eye test that detects the function of the retina (the light-detecting portion of the eye). The retina is comprised of layers of specialized cells, including photoreceptors (rods and cones), that detect light and ganglion cells that transmit images to the brain.

The electroretinography (ERG) test measures the electrical response of the retina to light. It is performed by placing an electrode on the cornea of the eye after it has been numbed with eye drops. Disorders of the retina can be evaluated with this test. It can also help to determine if retinal surgery may be helpful.

Electrodes are placed on the surface of the cornea (DTL silver/nylon fiber string or ERG jet) or on the skin beneath the eye (sensor strips) to measure retinal responses. Retinal pigment epithelium (RPE) responses are measured with an EOG test with …

What is an Electroretinogram? An Electroretinogram, commonly referred to as an ERG test, is a non-invasive diagnostic procedure that measures the retina’s electrical activity in response to light.

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 monitor a variety of retinal disorders.

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 measured by skin or corneal electrodes.

An electroretinogram (ERG) is a test that measures the response of the retina to light. These tests will help the doctor diagnose and monitor eye disorders. This test also monitors the changes caused by certain medicines.

Electroretinography (ERG) is an eye test that is used to detect abnormal function of the retina, which is the light-detecting portion of the eye. In this test, the rods, cones and light sensitive cells of the eyes are examined.
