Common Eye Problems in Cats and Their Treatments

Cats rely heavily on their vision for play, hunting, and exploring. So when eye problems occur, they can quickly impact quality of life. From watery discharge to cloudiness or even sudden blindness, feline eye issues should never be ignored.

In this guide, we’ll cover the most common eye problems in cats, their symptoms, and available treatments. Whether you’re a first-time cat owner or caring for a senior feline, knowing what to look for can help you protect your cat’s vision.

Signs of Eye Problems in Cats

Not all eye issues are obvious. Watch for these warning signs:

• Redness or swelling

• Watery or yellow/green discharge

• Squinting or frequent blinking

• Cloudiness or visible spots on the eye

• Pawing at the face

• Sensitivity to light

• Third eyelid showing

• Sudden clumsiness (possible vision loss)

Any of these can signal a serious feline eye condition needing veterinary care.

1. Conjunctivitis (Pink Eye in Cats)

Conjunctivitis is one of the most common eye problems in cats. It occurs when the conjunctiva—the pink tissue lining the eyelids—becomes inflamed.

Symptoms:

• Red, swollen eyelids

• Watery, yellow, or green discharge

• Squinting and discomfort

Causes:

• Viral infections (often feline herpesvirus)

• Bacterial infections

• Allergies or irritants

Treatment:

• Prescription eye drops or ointments (antibiotic or antiviral)

• Keeping the eye clean with vet-approved wipes

• Managing underlying conditions like feline herpesvirus

Note: Never use human eye drops on cats. Always consult a vet.

2. Corneal Ulcers

Corneal ulcers are painful sores on the surface of the eye, usually caused by trauma, scratches, or infections.

Symptoms:

• Cloudy or bluish eye

• Excessive tearing

• Squinting and visible discomfort

Causes:

• Scratches from other pets

• Foreign objects (dust, grass seeds)

• Severe untreated eye infections

Treatment:

• Antibiotic drops to prevent infection

• Pain relief prescribed by the vet

• In severe cases, surgery or grafting may be required

3. Cataracts

Cataracts cause the eye’s lens to become cloudy, impairing vision. While common in older cats, they can also result from injury or disease.

Symptoms:

• Cloudy, milky appearance in the eye

• Clumsiness or bumping into objects

• Vision loss in advanced cases

Causes:

• Aging

• Diabetes

• Trauma or genetic conditions

Treatment:

• Surgical removal (though less common in cats than dogs)

• Managing underlying health issues (like diabetes)

• Supportive care if vision loss is permanent

4. Glaucoma

Glaucoma occurs when fluid pressure builds up in the eye, damaging the optic nerve. It is a medical emergency.

Symptoms:

• Enlarged or bulging eye

• Severe pain (cat may hide or cry)

• Cloudy cornea

• Sudden blindness

Causes:

• Blocked drainage in the eye

• Secondary to other eye conditions (tumors, inflammation)

Treatment:

• Medications to reduce eye pressure

• Surgery in severe cases

• In advanced cases, removal of the affected eye may be necessary to relieve pain

5. Uveitis

Uveitis is inflammation inside the eye, often linked to infections or systemic diseases.

Symptoms:

• Red, painful eye

• Small, constricted pupil

• Cloudiness

• Sensitivity to light

Causes:

• Viral infections (feline leukemia, FIV)

• Bacterial or fungal infections

• Cancer or immune-mediated disease

Treatment:

• Anti-inflammatory medications

• Treating the underlying cause (e.g., infection)

• Pain management

6. Dry Eye (Keratoconjunctivitis Sicca)

Though less common in cats than in dogs, dry eye can occur when tear production decreases.

Symptoms:

• Thick, sticky discharge

• Redness

• Repeated eye infections

Causes:

• Immune system disorders

• Nerve damage

• Certain medications

Treatment:

• Artificial tears or lubricating eye drops

• Medications to stimulate tear production

7. Entropion

Entropion is a condition where the eyelid rolls inward, causing lashes to rub against the cornea.

Symptoms:

• Constant squinting

• Watery eyes

• Eye ulcers from irritation

Causes:

• Congenital (genetic)

• Chronic eye inflammation

Treatment:

• Surgical correction to reposition the eyelid

8. Eye Infections

Cats often get eye infections from viruses, bacteria, or even fungi.

Symptoms:

• Discharge (clear, yellow, or green)

• Swollen eyelids

• Sneezing and nasal discharge (if related to upper respiratory infections)

Treatment:

• Antibiotic or antiviral eye drops prescribed by a vet

• Cleaning discharge regularly

• Supportive care for respiratory symptoms

Home Care for Cats with Eye Problems

While professional treatment is essential, you can help at home by:

• Keeping eyes clean with a damp, soft cloth

• Using vet-approved saline drops (if recommended)

• Reducing dust and allergens in the environment

• Keeping claws trimmed to avoid self-injury

Never use human medications or over-the-counter drops—many are toxic to cats.

Preventing Eye Problems in Cats

Prevention is always better than treatment. You can reduce the risk of eye disease by:

• Scheduling regular vet checkups

• Keeping up with vaccinations (especially against feline herpesvirus and calicivirus)

• Maintaining good hygiene in food and litter areas

• Avoiding exposure to sick cats

• Providing a safe environment free of sharp objects or irritants

When to See the Vet Immediately

Seek urgent veterinary care if your cat has:

• Sudden vision loss

• Bulging eyes

• Heavy discharge with swelling

• Severe pain or hiding behavior

• Persistent cloudiness

Delaying treatment can result in permanent blindness or loss of the eye.

Common eye problems in cats range from minor infections to serious conditions like glaucoma or cataracts. The key is early detection and prompt veterinary treatment. By watching for warning signs, keeping up with vet visits, and maintaining a clean environment, you can help protect your cat’s vision for years to come.

Remember: healthy eyes mean a happier, safer, and more playful cat.
