Zusammenfassung	Electroretinography (ERG) is an electrophysiological technique that records the electrical activity generated by the retina in response to light stimulation. By measuring the amplitude and timing of the resulting potential, ERG provides objective assessment of retinal photoreceptor and bipolar cell function independent of the animal's ability to see. It is essential for diagnosing inherited retinal dystrophies, assessing retinal toxicity, and monitoring disease progression in both clinical and veterinary ophthalmology.	Polysomnography (PSG) is a comprehensive multi-channel physiological recording method that simultaneously records brain electrical activity, eye movements, muscle tone, respiratory effort, oxygen saturation, heart rate, and limb movements during sleep. First systematized by Rechtschaffen and Kales in 1968, polysomnography is the gold standard for diagnosing sleep disorders, characterizing sleep architecture, and assessing the quality and organization of sleep in humans and increasingly in veterinary species.
