Electroretinogram - EyeWiki
网页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.
Electroretinogram: Uses, Procedure, Results - Verywell Health
网页2022年3月14日 · An electroretinogram is designed to determine how well the light-sensitive retinal tissue is functioning. This test monitors the electrical activity that occurs in response to flashing lights in both dark and light conditions. The electroretinogram should take about 60–90 minutes to complete.
Full-Field Electroretinogram - StatPearls - NCBI Bookshelf
网页2023年8月28日 · The full-field electroretinogram (ffERG) is an ophthalmologic test that provides non-invasive objective quantitative measures of the electrical activity in the retina. The ffERG represents an electrical response from the retina to a flash of light and measures global retinal function. [1]
Electroretinography: Purpose, Procedure & Results - Healthline
网页2020年4月20日 · 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 - Wikipedia
网页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 cells.
The Electroretinogram and Electro-oculogram: Clinical …
网页2015年7月14日 · The global or full-field electroretinogram (ERG) is a mass electrical response of the retina to photic stimulation. The ERG is a test used worldwide to assess the status of the retina in eye diseases in human patients and in laboratory animals used as models of retinal disease.
Electroretinogram / Multifocal ERG | Wills Eye Hospital
网页An electroretinogram is a diagnostic procedure that evaluates the function of the retina, the light-sensitive lining on the back of the eye where light is focused. The retina can be affected by several different conditions that can lead to serious complications, including permanent vision loss.
Electroretinography (ERG) Waves, Procedure, Readings, Risks - MedicineNet
网页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 …
The Electroretinogram: ERG - Webvision - NCBI Bookshelf
网页2001年5月1日 · This light-induced electrical activity of the eye was called the electroretinogram. Now, the electroretinogram response is commonly abbreviated to the ERG. As early as 1865, Holmgren found that a light stimulus could cause a change in the electrical potential of the amphibian eye.
Pattern Electroretinogram - StatPearls - NCBI Bookshelf
网页2023年7月25日 · The pattern electroretinogram (PERG) is a specialized electrophysiologic test of central retinal function in response to a pattern reversing stimulus. There are standard protocols for eliciting the retinal electrical response.
