What causes a corneal ulcer in a cat? - briefly
A corneal ulcer in a cat is typically caused by trauma, such as scratches, foreign objects, or infections like feline herpesvirus. Additionally, dry eye syndrome or chemical irritants can contribute to its development.
What causes a corneal ulcer in a cat? - in detail
A corneal ulcer in a cat occurs when the outer layer of the cornea, known as the epithelium, is damaged, leading to an open sore. This condition can be caused by various factors, including trauma, infections, foreign bodies, and underlying health issues. Trauma is one of the most common causes, often resulting from scratches, bites, or exposure to sharp objects. Cats are naturally curious and may injure their eyes while exploring or during fights with other animals. Infections, particularly bacterial, viral, or fungal, can also lead to corneal ulcers. Feline herpesvirus is a prevalent viral infection that can cause recurrent eye issues, including ulcers. Foreign bodies, such as dust, dirt, or plant material, can irritate the cornea and lead to ulceration if not promptly removed. Additionally, dry eye syndrome, or keratoconjunctivitis sicca, can reduce tear production, leaving the cornea vulnerable to damage and ulceration. Certain breeds, like Persians and Himalayans, are more prone to developing corneal ulcers due to their facial structure and prominent eyes. Underlying conditions, such as entropion (inward rolling of the eyelid) or exposure keratitis (inadequate eyelid coverage), can also contribute to the development of ulcers. Lastly, chemical burns or exposure to irritants can damage the cornea. Early diagnosis and treatment are crucial to prevent complications, such as corneal perforation or vision loss.
