Electroretinography is a scientific term that refers to a diagnostic test for measuring the electrical activity in the retina. It is commonly used in ophthalmology to detect retinal disorders such as macular degeneration and glaucoma. However, there are various synonyms that can be used instead of electroretinography such as ERG, retinal electrography, and electrooculography. These terms are often used interchangeably by doctors and scientists to describe the same test, ensuring clear communication and accuracy in diagnosis. Other terms that are related to this field include electrodiagnostic testing, electrophysiology, and visual function testing which are used to evaluate different aspects of the visual system.
