Seeing your cat with a swollen eye can be alarming, especially when their normally bright and curious gaze is replaced with a squinted, uncomfortable expression.
While a slight swelling might be a minor irritation, a swollen eye that’s closed shut, watery, or bulging could be a sign of a more serious condition.
This article why is my cat eye swollen; dives into the world of feline eye swelling, exploring the diverse range of causes, offering insights into potential complications, and guiding you towards effective solutions.
We’ll break down complex medical jargon into easy-to-understand language, using real-life case studies to illustrate the journey towards a happy, healthy, and clear-eyed kitty.
Understanding Feline Eye Swelling: A Closer Look
Imagine your eye feeling inflamed, tender, and even painful to the touch. This is the experience your cat might be enduring when their eye is swollen.
Swelling around the eye, often accompanied by redness, discharge, and even a squinting expression, can be a sign of a variety of conditions, from minor irritations to more serious infections or injuries.
1. Conjunctivitis: Inflammation of the Conjunctiva
Conjunctivitis, an inflammation of the conjunctiva, the clear membrane covering the white part of the eye and the inner eyelid, is a common cause of eye swelling.
- Symptoms: Swelling around the eye, redness, discharge (clear, white, yellow, or green), and possibly a squinting expression.
- Causes: Allergies, infections (bacterial, viral, or fungal), irritants (dust, pollen, smoke), and even dry eye can cause conjunctivitis.
- Diagnosis: Based on clinical signs and possibly confirmed with a swab of the discharge to identify the cause.
- Treatment: Eye drops or ointments, often containing antibiotics, antivirals, or antifungals, depending on the underlying cause.
Case Study: Charlie’s Conjunctivitis
Charlie, a 4-year-old tabby, had a swollen eye, redness, and clear discharge.
His veterinarian diagnosed conjunctivitis and prescribed antibiotic eye drops. After a week of treatment, Charlie’s eye swelling and discharge resolved.
2. Corneal Ulcers: Open Sores on the Cornea
Corneal ulcers, open sores on the cornea, the clear outer layer of the eye, can cause pain, swelling, and discharge.
- Symptoms: Swelling around the eye, redness, discharge, squinting, and possibly a cloudy appearance to the cornea.
- Causes: Trauma, infections, dry eye, and certain medications can cause corneal ulcers.
- Diagnosis: Based on clinical signs, often confirmed with a fluorescein stain test, which highlights the ulcer.
- Treatment: Eye drops or ointments, often containing antibiotics, to treat the infection and promote healing. In some cases, surgery might be required to repair severe ulcers.
Case Study: Lily’s Corneal Ulcer
Lily, a 7-year-old Persian, had a swollen eye, redness, and a cloudy appearance to her cornea. Her veterinarian diagnosed a corneal ulcer and prescribed antibiotic eye drops.

Keratitis, an inflammation of the cornea, can cause swelling, redness, and discomfort.
- Symptoms: Swelling around the eye, redness, discharge, squinting, and possibly a cloudy appearance to the cornea.
- Causes: Infections, trauma, allergies, and dry eye can cause keratitis.
- Diagnosis: Based on clinical signs and possibly confirmed with a fluorescein stain test.
- Treatment: Eye drops or ointments, often containing antibiotics, to treat the infection and reduce inflammation.
Case Study: Max’s Keratitis
Max, a 9-year-old Siamese, had a swollen eye, redness, and a cloudy appearance to his cornea.
His veterinarian diagnosed keratitis and prescribed antibiotic eye drops. After a few weeks of treatment, Max’s eye swelling and cloudiness resolved.
4. Uveitis: Inflammation Inside the Eye
Uveitis, an inflammation of the middle layer of the eye, known as the uvea, can cause pain, swelling, and cloudiness.
- Symptoms: Swelling around the eye, redness, discharge, squinting, and possibly a cloudy appearance to the cornea.
- Causes: Infections, trauma, and immune system disorders can cause uveitis.
- Diagnosis: Based on clinical signs, often confirmed with a dilated eye exam to visualize the uvea.
- Treatment: Eye drops or ointments containing corticosteroids to reduce inflammation, as well as antibiotics to treat infections.
Case Study: Oliver’s Uveitis
Oliver, a 12-year-old tabby, had a swollen eye, redness, and a cloudy appearance to his cornea.
His veterinarian diagnosed uveitis and prescribed corticosteroid eye drops. After a few weeks of treatment, Oliver’s eye swelling and cloudiness resolved.
5. Glaucoma: Increased Pressure Inside the Eye
Glaucoma, a condition where the pressure inside the eye increases, can cause swelling, pain, and vision loss.
- Symptoms: Swelling around the eye, redness, pain, and possibly a cloudy appearance to the cornea.
- Causes: Glaucoma can be caused by various factors, including genetic predisposition, aging, and eye injuries.
- Diagnosis: Based on clinical signs, often confirmed with tonometry, a test to measure eye pressure.
- Treatment: Eye drops to lower eye pressure and possibly surgery in severe cases.
Case Study: Bella’s Glaucoma
Bella, an 8-year-old Siamese, had a swollen eye, redness, and seemed to be in pain.
Her veterinarian diagnosed glaucoma and prescribed eye drops to lower eye pressure. Bella’s condition was managed with medication.
6. Cataracts: Clouding of the Lens
Cataracts, a clouding of the lens of the eye, can cause blurred vision and sometimes lead to swelling around the eye.
- Symptoms: Blurred vision, cloudy appearance to the lens, and possibly swelling around the eye.
- Causes: Cataracts can be caused by various factors, including aging, diabetes, and genetic predisposition.
- Diagnosis: Based on clinical signs and often confirmed with a dilated eye exam.
- Treatment: Surgery to remove the cloudy lens and replace it with an artificial lens.
Case Study: Charlie’s Cataracts
Charlie, a 6-year-old tabby, had a cloudy appearance to his eye and seemed to be bumping into things.
His veterinarian diagnosed cataracts and recommended surgery. After the surgery, Charlie’s vision improved significantly.
7. Eyelid Problems: Entropion, Ectropion, and Tumors
Eyelid problems, such as entropion (inward rolling of the eyelid), ectropion (outward rolling of the eyelid), and tumors, can cause irritation, inflammation, and swelling.
- Symptoms: Swelling around the eye, redness, discharge, squinting, and possibly hair loss around the eyelid.
- Causes: Congenital defects, aging, and tumors can cause eyelid problems.
- Diagnosis: Based on physical examination and often confirmed with imaging studies, such as X-rays.
- Treatment: Surgery to correct eyelid abnormalities or to remove tumors.
Case Study: Lily’s Entropion
Lily, a 4-year-old Persian, had a swollen eye and excessive tearing.
Her veterinarian diagnosed entropion and recommended surgery to correct the eyelid. After the surgery, Lily’s eye swelling and tearing decreased.
8. Foreign Objects: Irritants in the Eye
Small objects, like dust particles, grass seeds, or even tiny insects, can become lodged in the eye, causing irritation, inflammation, and swelling.
- Symptoms: Swelling around the eye, redness, discharge, squinting, and possibly pain.
- Causes: Anything that gets into the eye can irritate it, especially if it’s sharp or irritating.
- Diagnosis: Based on clinical signs and often confirmed with a thorough examination of the eye.
