My Pet Folio

Corneal ulcers are open sores on the cornea (the clear surface of the eye) that can be caused by trauma, foreign objects, chemical burns, infections, or underlying health conditions. They range from superficial to deep and can progress rapidly.

Signs:

Squinting or keeping the eye closed
Excessive tearing or discharge
Rubbing at the eye
Redness and swelling
Cloudiness or haziness of the cornea
Visible depression or irregularity on eye surface (in severe cases)
Sensitivity to light
Pawing at the affected eye

Risk Factors:

Breed predisposition: Brachycephalic (flat-faced) breeds like Pugs, Bulldogs, Persians
Insufficient tear production: Dry eye (keratoconjunctivitis sicca)
Eyelid abnormalities: Entropion, ectropion, or distichiasis
Environmental: Exposure to irritants, rough play, outdoor activities

First Aid:

Prevent further rubbing or scratching (an e-collar is ideal).
Gently flush the eye with sterile eye wash solution if available.
Do not apply any medications unless directed by a veterinarian.
Seek veterinary care promptly - corneal ulcers can worsen quickly.

Important Warning

Never use human eye medications on pets without veterinary guidance. Some human products contain steroids which can worsen corneal ulcers and potentially lead to vision loss.
