The electroretinogram ERG is a diagnostic test that measures the electrical activity generated by neural and non-neuronal cells in the retina in response to a light stimulus. The electrical response is a result of a retinal potential generated by light-induced changes in the flux of transretinal ions, primarily sodium and potassium. Most often, ERGs are obtained using electrodes embedded in. For example, it may be combined with an antibiotic to treat chronic Q-fever, which humans usually catch from farm animals or raw milk.
