Is Your Cat's Eye Problem Actually Entropion?

If your cat has been squinting, tearing up, or dealing with eye discharge that keeps coming back despite treatment, the eyelid itself might be what’s going on. Entropion is a condition where the eyelid rolls inward, causing fur or lashes to rub directly against the surface of the eye. That constant friction is painful, and left untreated, it can cause lasting damage to the cornea.

The good news? It’s very treatable once it’s properly identified.

What does entropion look like in cats?

You’re not going to see a rolled eyelid at first glance. What you’ll notice is how your cat is acting. Feline entropion symptoms tend to show up as:

• Squinting or keeping one eye partially closed
• Excessive tearing or watery discharge around the eye
• Thick or crusty eye discharge (clear, yellow, or green)
• Pawing or rubbing at the face
• Redness around the eye
• A visible third eyelid (that pale membrane creeping in from the inner corner)
• Sensitivity to light

One-sided symptoms are a red flag. If only one eye is affected and it keeps coming back, that’s worth investigating beyond a standard eye infection.

What causes entropion in cats?

There’s more than one reason a cat’s eyelid can start rolling inward, and the type matters because it changes what treatment looks like.

Type	What’s happening	Who it affects
Spastic entropion	The most common type. An existing eye problem like a corneal ulcer, conjunctivitis, or feline herpesvirus causes the eyelid muscles to spasm and pull the lid inward. Treat the underlying cause and the entropion often resolves on its own.	Any cat with an underlying eye condition
Anatomical (breed-related) entropion	A structural issue, not triggered by another condition. Flat-faced breeds are built in a way that naturally predisposes them to eyelid rolling.	Persians, Himalayans, British Shorthairs
Congenital entropion	Some cats are simply born with it. It can show up in kittens before their eyes fully open and usually requires early intervention to prevent lasting corneal damage.	Kittens, any breed
Age-related (involutional) entropion	As cats age, loss of muscle tone and fat around the eye socket can cause the eyeball to sink slightly, pulling the lower lid inward with it.	Senior cats

When a “stubborn eye infection” is actually entropion

Spastic entropion is frequently misdiagnosed as conjunctivitis (eye inflammation, often called “pink eye”) or a corneal ulcer (a painful scratch or sore on the eye’s surface) that just won’t heal.

The pattern tends to look like this: a cat gets antibiotic eye drops, the eye improves a little, then flares again. The owner comes back. More drops. Same cycle. What hasn’t been checked is whether the eyelid itself is part of the problem.

Here are the red flags that suggest entropion rather than a simple infection:

• Symptoms keep returning after treatment
• Only one eye is affected, consistently
• A corneal ulcer isn’t healing despite appropriate medication
• Trichiasis (fur or lashes visibly touching the eye surface) is present on close inspection
• Antibiotics help temporarily but never fully resolve the issue

If this sounds familiar, don’t hesitate to bring it up at your next vet visit. It’s a reasonable question and worth asking.

How vets diagnose entropion

Diagnosing entropion is pretty straightforward, and none of the tests involved are invasive. Most can happen during a standard vet visit. Here’s what to expect:

• Visual exam: Your vet will look closely at the eyelid position and gently manipulate the lid to see exactly how it’s sitting against the eye.
• Topical anesthetic test: Numbing drops are applied to the eye. If the entropion improves once the spasm relaxes, that tells the vet it’s likely spastic rather than structural, which changes the treatment path.
• Fluorescein stain: A bright orange dye is applied to the eye surface. Under a special light, any corneal scratches or ulcers show up as glowing green patches, giving the vet a clear picture of how much damage has already occurred.
• Schirmer tear test: A small strip of paper is placed at the edge of the eye for a minute to measure tear production. This helps rule out dry eye as a contributing factor.

Treatment options for feline entropion

Treatment depends on what type of entropion your cat has and how old they are. Here’s how each scenario typically plays out:

For spastic entropion 

The first step is treating whatever triggered the eyelid spasm in the first place. If feline herpesvirus, a corneal ulcer, or conjunctivitis is the culprit, resolving that often resolves the entropion too. In the meantime, temporary tacking sutures, which are small stitches that hold the lid in the correct position while healing happens, can give the eye some much-needed relief.

For structural or congenital entropion 

This type usually needs surgery to fix properly. The most common procedure is called the Hotz-Celsus procedure, where a small strip of skin is removed from the eyelid to pull it back into the right position. It’s a precise surgery that’s typically performed by a veterinary ophthalmologist, a vet who specializes in eye conditions.

For age-related entropion 

For older cats who may not be the best candidates for surgery, hyaluronic acid eyelid injections offer a less invasive alternative. A small amount of filler is injected near the eyelid to restore volume and gently push the lid back into place. It’s not a permanent fix, but it can provide meaningful relief and buy your cat a lot more comfort.

What does entropion surgery cost, and does insurance cover it?

Cat entropion surgery typically runs between $1,000 to $3,000 or more, depending on the severity, whether a specialist is involved, and your location. Add in diagnostics, pre-surgical bloodwork, anesthesia, and post-op medications, and the total climbs quickly. It’s not something most people budget for until they’re already in the middle of it.

A Lemonade accident and illness policy can help cover eligible costs related to entropion, including diagnostics and surgery, as long as the condition isn’t pre-existing. That means your cat shouldn’t be showing any signs or symptoms of entropion before your policy starts or during your waiting period. If you have a Persian, Himalayan, or another brachycephalic breed, getting coverage in place before any eye issues develop is especially worth thinking about early.

Before we go

A squinting, watery, or discharge-filled eye that keeps coming back despite treatment is worth investigating beyond a standard infection. Entropion is painful, and the longer it goes unaddressed, the greater the risk of lasting corneal damage. If something feels off about your cat’s eye, trust that instinct and bring it up with your vet.

And whatever breed you have, getting coverage in place while your cat is healthy just makes sense.
