Does this sign require immediate hospital care?

If there is only mild tearing or brief squinting, observe closely for 24 to 48 hours. If signs persist, worsen, or vision is affected, seek veterinary evaluation promptly.

How can I judge the severity of keratitis?

Assess pain level, tear amount, discharge type, and corneal appearance, such as cloudiness or ulcers. Obvious vision impairment or worsening signs are more serious.

What observations or preparation can I do at home?

Prevent the pet from rubbing the eye, record which eye is affected and timing of signs, and take photos or videos for clinical comparison. Avoid self-medicating or nonprofessional treatment.

When should I go to emergency care immediately?

Heavy bleeding, obvious purulent discharge, sudden vision loss, or severe pain that cannot be relieved should prompt immediate hospital or emergency care.

What this symptom means clinically

Keratitis is an inflammatory reaction of corneal tissue, often caused by infection, trauma, or imbalance in surface protection. Inflammation damages the corneal epithelium, causes vascular dilation and cloudiness, and increases pain sensation and tear production. Severe or deep disease may lead to corneal ulceration or scarring and affect visual clarity.

🐱 In cats

Keratitis in cats is often related to viral infection, such as feline herpesvirus, or trauma. Signs may be subtle and recurrent.

🐶 In dogs

Keratitis in dogs is often related to dry eye, foreign material, bacterial infection, or corneal ulceration, and pain and squinting are usually more obvious.
