Electroretinography: A test in which the electrical potentials generated by the retina of the eye are measured when the retina is stimulated by light. Abbreviated ERG. The instrument used to conduct ERG is an electroretinograph, and the resultant recording is called an electroretinogram..
Keeping this in view, what does the prefix ERG mean?
ργον), a Greek word meaning 'work' or 'task'. An erg is the amount of work done by a force of one dyne exerted for a distance of one centimetre. In the CGS base units, it is equal to one gram centimetre-squared per second-squared (g⋅cm2/s2).
what does an ERG look like? 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. They form part of the back of the eye known as the retina.
Accordingly, what does an ERG test for?
Electroretinography (ERG) is an eye test that detects 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.
What is multifocal ERG test?
Multifocal ERG uses visual stimuli from a computer screen to elicit electrical responses from different areas within the retina. The electrical energy created is measured by the Diopsys® mfERG vision test, and used to create a report for your doctor. It is similar to an EKG, but for your eyes.
