Corneal ulcers in horses are serious open sores on the surface of the eye, most often caused by injuries, infections, or foreign material like dust or plant debris. Affected horses may show squinting, tearing, redness, cloudiness, or sensitivity to light, and some may rub the eye due to discomfort. Because the cornea is essential for clear vision, untreated ulcers can lead to scarring or permanent vision loss, impacting a horse’s safety and performance. Quick recognition and prompt veterinary attention are crucial to prevent complications and support full healing.
