सारांश	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.	Equine Gait Analysis is a systematic evaluation of a horse's movement patterns at walk, trot, and canter to detect lameness, asymmetry, and biomechanical dysfunction. Combining visual observation with increasingly sophisticated instrumental techniques (force plate analysis, kinematics, accelerometry), gait analysis is essential for diagnosing the causes of lameness, monitoring recovery from injury, and evaluating the safety and suitability of sport horses.	Focal Animal Sampling (FAS) is a systematic observational method in which an observer focuses on one individual animal at a time, recording its behavior continuously or at regular intervals for a fixed period. Introduced by Jeanne Altmann in 1974, FAS provides detailed, quantitative ethograms of individual behavior, making it essential for studying animal behavioral ecology, welfare, and responses to environmental changes.
