What does ERG stand for?

Explanation:
The ERG is the recording of the retina’s electrical response to light, so it stands for electroretinogram. It reflects the summed electrical activity of photoreceptors and retinal neurons as they react to a light stimulus, which is why this term specifically denotes the waveform that’s measured. The other terms refer to different things: the instrument used to capture the signal would be an electroretinograph, the broader procedure or field is electroretinography, and electroretinal potential points to a different electrical concept. So the best fit for what ERG stands for is electroretinogram.
