Pet Corneal Ulcer Symptom Guide | What to Watch For and When to Seek Care
Understand possible causes of Corneal Ulcer and key home observations
Corneal ulcer is an eye sign that needs timely attention. Observe and record changes to support veterinary evaluation.
What this symptom means clinically
A corneal ulcer is a localized defect in the corneal epithelium or deeper stroma, often caused by trauma, exposure, or infection that damages the epithelium and exposes deeper tissue. Ulcers alter corneal clarity and cause painful responses such as increased blinking, eye closure, or abnormal tearing. Deep or nonhealing ulcers can change corneal structure and affect vision.
🐱 In cats
In cats, corneal ulcers are often associated with viral keratitis or minor trauma and may recur or accompany chronic corneal changes.
🐶 In dogs
In dogs, corneal ulcers are commonly caused by trauma, foreign material, or abrasion. Acute traumatic ulcers are more common and may progress quickly.
