ERG

ERG stands for electroretinography, a test in which the electrical potentials generated by the retina of the eye are measured when it is stimulated by light. In an ERG, an electrode is placed on the cornea at the front of the eye. The electrode gauges the electrical response of the rods and cones, the visual cells in the back of the retina. An ERG is useful in the evaluation of hereditary and acquired disorders of the retina. A normal ERG shows the appropriate responses with increased light intensity. An abnormal ERG is found in conditions such as arteriosclerosis of the retina, detachment of the retina, and temporal arteritis with eye involvement. The instrument used to do electroretinography is an electroretinograph and the resultant recording is called an electroretinogram. ERG can also stand for electroretinograph or electroretinogram. According to "Medical Acronyms, Eponyms & Abbreviations" by Marilyn Fuller DeLong, ERG is also an acronym for "electrolyte replacement with glucose" (although we have never heard it used in this context).
