15 Cat Eye Problems to Look Out For

Eyes are among the most delicate organs in your cat’s body. It’s crucial to spot eye problems early to preserve your cat’s vision and overall well-being. This guide outlines 15 common cat eye problems every pet parent should know, including typical causes, symptoms, treatments, and prevention tips. If you notice changes in your cat’s eyes, don’t hesitate to seek a veterinarian’s advice.

Why Cat Eye Health Matters

Healthy eyes are vital for your cat’s quality of life. Untreated eye issues can lead to discomfort, pain, blindness, or even systemic illness. Keeping your cat’s eyes clean and regularly inspecting them helps you notice problems before they worsen.

1. Pink Eye (Conjunctivitis)

Conjunctivitis—commonly known as pink eye—is the most frequent feline eye disorder. It involves inflammation of the conjunctiva, the membrane covering the white of the eye and lining the eyelids.
Main causes: feline herpesvirus-1 (FHV-1), bacterial infections, foreign objects.

  • Symptoms: Redness, swelling, squinting, watery or pus-like discharge, pawing at eyes.
  • Treatment: Antibiotic or antiviral medications as prescribed by your veterinarian.
  • Prognosis: Most cases resolve with proper care; some may become chronic.

2. Keratitis

Keratitis is inflammation of the cornea, the transparent front layer of the eye, often due to FHV-1.
Repeated episodes can lead to vision loss if untreated.

  • Symptoms: Cloudy, red, swollen, watery eyes, oozing discharge.
  • Causes: Viral (most common), bacterial infections, trauma.
  • Treatment: Antibiotics, antiviral medications, sometimes surgery for severe cases.

3. Cataracts

Cataracts result in the lens becoming cloudy, whitish, or bluish—often giving the pupil a foggy appearance. This prevents light from reaching the retina, impairing vision.

  • Symptoms: Visible cloudiness in one or both eyes, behavioral changes (bumping into objects, trouble finding things, less jumping).
  • Causes: Aging, diabetes, genetics, trauma, inflammation.
  • Treatment: Surgical removal is possible, but many cats adapt well with impaired vision.

4. Glaucoma

Glaucoma arises when fluid cannot drain properly inside the eye, increasing pressure and damaging the optic nerve.

  • Symptoms: Eye pain, cloudiness, watery discharge, enlarged eyeball, vision loss.
  • Treatment: Medications to lower pressure, surgery in severe cases.
  • Prognosis: Early treatment is vital to preserve vision.

5. Corneal Ulcers

A corneal ulcer is a sore on the cornea caused by trauma, infections, or dry eye. It is painful and can lead to blindness if untreated.

  • Symptoms: Red, inflamed, cloudy eyes, squinting, excessive blinking, discharge.
  • Treatment: Antibiotic eye drops, pain relief, sometimes surgical intervention.

6. Uveitis

Uveitis is inflammation of the uvea (the middle layer inside the eye). It can have many causes: infections, injury, cancer, autoimmune conditions.

  • Symptoms: Red eye, sensitivity to light, cloudy appearance, pain.
  • Treatment: Steroid or anti-inflammatory drops, addressing the underlying cause.

7. Entropion & Ectropion

ConditionDescriptionTreatment
EntropionEyelid turns inward, lashes rub against the eye.Surgical correction.
EctropionEyelid droops outward, exposing more eye surface.Lubricating drops or surgery.

8. Blepharitis

Blepharitis is inflammation of the eyelids, often seen as swelling, redness, crusting, or discharge.

  • Causes: Bacterial, fungal infections, allergies, parasites.
  • Treatment: Cleansing, medicated ointments as directed by your vet.

9. Cherry Eye

Cherry Eye is a prolapse of the third eyelid gland causing a pink swelling in the inner corner of the eye.

  • Symptoms: Pink or red lump at the inner corner.
  • Treatment: Surgery is usually required.

10. Eye Trauma

Physical injury, scratches or foreign objects can lead to swelling, bleeding, or infection.
Immediate veterinary care is essential for eye injuries.

  • Symptoms: Visible damage, pain, squinting, excessive tearing, bloody discharge.

11. Blocked Tear Ducts (Epiphora)

Blocked tear ducts cause excessive tearing which can stain your cat’s fur. Flat-faced (brachycephalic) breeds are especially prone.

  • Symptoms: Watery discharge, tear-stained fur below eyes.
  • Causes: Genetic defects, previous conjunctivitis, scarring, trauma.
  • Treatment: Cleaning, vet may flush ducts or treat infections.

12. Allergies

Like humans, cats can suffer allergies which often manifest as eye symptoms.

  • Symptoms: Red, itchy, watery eyes, sneezing, nasal discharge.
  • Treatment: Identifying and removing allergen, vet-prescribed anti-allergy medication.

13. Foreign Bodies

Material such as dust, fur, or grass blades can irritate the eye.
Never try to remove objects yourself—seek veterinary help.

  • Symptoms: Squinting, excessive blinking, visible debris, pawing at eye.
  • Treatment: Veterinary removal and aftercare.

14. Dry Eye (Keratoconjunctivitis Sicca)

Dry eye occurs when the tear glands don’t produce enough moisture. It’s uncomfortable and can lead to chronic infection.

  • Symptoms: Redness, thick discharge, cloudiness, squinting.
  • Treatment: Lubricating eye drops, treating underlying cause.

15. Eye Tumors

Rare but potentially serious, tumors can grow on or behind the eye, causing pressure, vision loss and pain.

  • Symptoms: Swelling, asymmetry, protrusion, abnormal pupil shape.
  • Treatment: Surgery, possible chemotherapy or radiation, depending on diagnosis.

Recognizing Cat Eye Symptoms

Regardless of the underlying problem, some common warning signs signal it’s time for a veterinary visit:

  • Persistent redness, swelling, or puffiness
  • Cloudy or bluish pupils
  • Discharge: clear, colored, or pus-like
  • Squinting, frequent blinking, light sensitivity
  • Behavior changes: bumping into objects, reluctance to jump
  • Pawing or scratching at eyes
  • Noticeable pain or sensitivity when touching the face

Early diagnosis dramatically improves outcomes for most eye conditions.

Causes of Cat Eye Problems

  1. Infections: Viruses (FHV-1), bacteria, fungi, parasites
  2. Trauma: Scratches, foreign bodies, accidents
  3. Congenital Defects: Blocked tear ducts, eyelid abnormalities
  4. Allergies: Environmental, food, chemical
  5. Systemic Illness: Diabetes, immune disorders, cancer

Diagnosis and Treatment Options

Diagnosis typically involves a thorough eye exam, fluorescein stains for ulcers, and sometimes swabs for infection or bloodwork. Imaging may help in cases of tumors or glaucoma.

  • Medications: Antibiotic or antiviral eye drops, anti-inflammatory drugs, lubricants.
  • Surgical Interventions: For entropion, cherry eye, severe cataracts, tumors.
  • Supportive Care: Keep your cat comfortable, indoors, with familiar surroundings if vision is impaired.

Tips to Keep Your Cat’s Eyes Healthy

  • Inspect eyes regularly for redness, swelling, discharge, or cloudiness.
  • Gently wipe away discharge using a damp cotton pad (never use harsh chemicals).
  • Maintain regular veterinary checkups and vaccinations, especially for feline herpesvirus.
  • Minimize allergen exposure (dust, strong perfumes, smoke).
  • Protect cats from trauma—keep sharp objects and hazardous plants out of reach.
  • Promptly seek veterinary care for any changes in eye appearance or behavior.

Frequently Asked Questions (FAQs)

Q: Can cat eye problems go away on their own?

A: Some mild cases, like allergic conjunctivitis, may resolve naturally. However, most eye problems require timely veterinary diagnosis and treatment to prevent permanent damage.

Q: Is cat eye discharge always a sign of infection?

A: Not always. Discharge can also result from blocked tear ducts, allergies, or foreign matter. Persistent, colored, or pus-like discharge should always be evaluated by a veterinarian.

Q: Can cats with cataracts still lead a normal life?

A: Generally, yes. Many cats adapt remarkably well to impaired vision. Safety measures and possible surgery can help maintain their quality of life.

Q: Are certain breeds more prone to eye problems?

A: Yes. Flat-faced breeds (Persians, Himalayans) are more susceptible to blocked tear ducts and other problems. Genetics play a role in predisposition.

Q: Should I clean my cat’s eyes routinely?

A: Clean only visible discharge with a damp cotton pad when needed. Routine cleaning without visible discharge isn’t necessary and may irritate the eyes.

When to Call the Vet

Any sudden eye changes—including persistent redness, swelling, puffiness, discharge, visible trauma, or changes in vision—warrant immediate veterinary attention. Never delay seeking help to avoid complications and safeguard your cat’s sight.

Conclusion

Feline eye problems can range from mild and transient to severe and vision-threatening. Vigilance, prompt veterinary care, and regular eye checks are essential to ensure your cat’s eyes remain healthy throughout their life.
