Regarding corneal ulceration in horses, which statement is correct?

• A. It is very common and can be sight threatening
• B. It is rare and usually benign
• C. It never progresses rapidly
• D. It affects only aged horses

Answer: (A)

Corneal ulcers in horses are a frequent ocular problem that can threaten vision, making prompt recognition and treatment essential. The statement that best fits is that these ulcers are very common and can be sight threatening because even small ulcers can become serious if infection sets in or the corneal tissue begins to melt, leading to perforation or severe scarring. Horses are prone to traumatic or infectious keratitis, and rapid progression is possible, especially with bacterial or fungal organisms that release proteolytic enzymes. This is why timely veterinary evaluation and aggressive management are crucial to preserve sight.

That’s why other descriptions don’t fit: corneal ulcers aren’t rare or typically benign, they can progress quickly rather than never progressing rapidly, and they are not restricted to aged horses. They can affect horses of any age and, if untreated, may lead to serious outcomes. Signs to watch for include tearing, squinting, sensitivity to light, and discharge, and the priority is prompt care to prevent vision loss.
