Feline Corneal Ulcer: Causes and Treatment

Understanding Corneal Ulcers in Cats

A corneal ulcer in a cat is a painful condition that can cause discomfort and potentially lead to vision loss if not treated promptly. The cornea is the clear, outer layer of the eye, and when it becomes damaged, it can lead to an ulcer.

What is a Corneal Ulcer in Cats?

A corneal ulcer is a break or defect in the cornea of a cat’s eye. These ulcers can occur due to various causes, such as trauma, infection, or underlying health conditions. The severity of a corneal ulcer can vary from a superficial scratch to a deep wound.

How Do Cats Get Corneal Ulcers?

Corneal ulcers in cats can develop due to several reasons. One of the most common causes is trauma to the eye, such as getting scratched by another animal or being hit by a car. Additionally, eye infections caused by bacteria, viruses, or fungi can lead to the development of corneal ulcers. Certain underlying health conditions, such as dry eye syndrome or entropion, can also increase a cat’s risk of developing corneal ulcers.

What are the Symptoms of Corneal Ulcers in Cats?

Cats with corneal ulcers can experience a range of symptoms, including redness, tearing, squinting, or pawing at the affected eye. Other signs may include discharge from the eye, cloudiness or opacity in the cornea, and sensitivity to light. If left untreated, corneal ulcers can worsen, leading to decreased vision or even blindness.

How Are Corneal Ulcers Diagnosed in Cats?

To diagnose a corneal ulcer in a cat, a veterinarian will perform a thorough eye exam. This may involve using specialized tools to examine the eye and measure tear production.
