Commentary: Visual electrophysiology and laboratory-specific normative values – How important are they?

Electrophysiology tests are noninvasive methods that study the response of our nervous system to various sensory stimuli. The most commonly used tests in visual electrophysiology are the visual evoked potential (VEP), electroretinogram (ERG), and the electrooculogram (EOG). Despite the technology being around for long, there is lack of reproducibility in the readings of these tests between two laboratories. The International Society for Clinical...
