Topic:Vision
Vision in horses involves the study of the anatomical and physiological aspects of the equine visual system, including how horses perceive their environment. The equine eye is adapted for a wide field of view, important for detecting predators. Horses have dichromatic vision, meaning they see a limited color spectrum compared to humans. Their vision is adapted for low-light conditions, which is beneficial for dawn and dusk activity. Research in this area explores various aspects such as visual acuity, depth perception, and the impact of eye diseases on equine vision. This page compiles peer-reviewed research studies and scholarly articles that investigate the structure, function, and clinical implications of vision in horses.
Intracranial myiasis by Hypoderma bovis (Linnaeus) in a horse. Acute neurologic disease associated with intracranial migration of a first instar larva of a warble fly, Hypoderma bovis (Linnaeus), was observed in a 14-year-old Quarter Horse gelding in western Montana. The disease was characterized by incoordination of gait, circling to the left, head tilt to the right, partial paralysis of the right side of the face, and impaired vision in the right eye. Two and one-half hours after it was first noticed sick, the horse collapsed and was euthanized. Massive hemorrhage unaccompanied by necrosis or significant cellular response was present in the right side o...
