Apr 20, 2020 · An electroretinography (ERG) test, also known as an electroretinogram, measures the electrical response of the light-sensitive cells in your eyes. These cells are known as rods and cones.

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 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.

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.

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.

An electroretinogram (ERG) test performed in 2014. A historical photo of a patient undergoing an electroretinogram. Clinically used mainly by ophthalmologists the electroretinogram (ERG) is used for the diagnosis of various retinal diseases.

Electroretinography is an electrophysiological test of the retina, the layer of the eye which detects light. The electroretinogram (ERG) is to the retina what the electrocardiogram (ECG) is to the heart.

Learn about the Electroretinogram (ERG) test, a key diagnostic tool for retinal health. Discover its purpose, procedure, and how it helps detect vision disorders.

ERG and VEP are specialized tests that help measure how your eyes and brain respond to visual stimuli. They provide essential insights into retinal function and optic nerve health, helping our eye doctors detect issues that may not show up during routine exams.

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.
