Entropion in Dogs: How Surgery Helped Luna’s Painful Eye

A Sore Eye That Needed Attention

Luna is a sweet but nervous 4-year-old Shar Pei x Bull Arab who came to see Dr Nicole with a very sore right eye.

It was our first time meeting Luna, so we didn’t know her full history, but her owner told us she’d never had any eye problems before.

Her eye was very squinty, and the eyelids were swollen. The swelling had caused her lower eyelid to curl inwards, which meant her eyelashes were rubbing against the surface of her eye.

This constant irritation had already resulted in a painful corneal ulcer.

We started Luna on antibiotic eye ointment to lubricate the eye and help the ulcer heal, along with anti-inflammatories to reduce the swelling.

Unfortunately, even with treatment, her lower eyelid continued to roll inwards and irritate her eye.

“Entropion causes the eyelid to roll inwards, allowing the eyelashes or surrounding hair to rub against the eye.”

Deciding How to Correct Luna’s Eyelid

There were two options to consider: temporary tacking sutures or permanent entropion surgery. In Luna’s case, we decided the permanent surgery was the better option.

This procedure involved removing a small amount of skin from Luna’s lower eyelid to bring it back into a normal position and stop her eyelashes rubbing against her cornea.

The swelling can make it difficult to judge exactly how much skin needs to be removed, and sometimes it takes more than one surgery to get the correction right. We don’t want to overestimate how much skin to take, particularly while the eyelid is swollen.

What Causes Entropion in Dogs?

Entropion occurs when an eyelid rolls inwards and the eyelashes or surrounding hair rub against the eye. Some breeds, including Shar Peis, are particularly prone to it because of their facial conformation and excess skin. This is known as primary or conformational entropion and is often seen in younger dogs.

But secondary or acquired entropion can also develop later as a result of eye irritation, trauma or changes to the fat and muscle surrounding the eye.

We don’t know exactly what caused Luna’s original eye irritation. However, because of her predisposition, it didn’t take much for a sore eye to cause swelling and eyelid spasm. The lower lid then rolled inwards, causing further irritation and allowing the problem to persist.

“Just five days after surgery, Luna’s corneal ulcer had fully healed and her eyelashes were no longer rubbing against her eye.”

A Very Happy Five-Day Recheck

After surgery, Luna wore an e-collar to stop her rubbing her eye or damaging her sutures while everything healed.

When she returned five days later, the difference was impressive. Her eye looked completely normal again, the corneal ulcer had fully healed, and the eyelid swelling was gone. Most importantly, her eyelashes were no longer rubbing against her eye.

Her owner had already noticed a big improvement the day after surgery and said Luna seemed much, much more comfortable. The family had understandably been worried that she might permanently lose vision in the affected eye, so they were very pleased with the outcome.

With her eyelid now surgically corrected, we don’t expect Luna’s entropion to recur.

Frequently Asked Questions

What is entropion in dogs?

Entropion is a condition where the eyelid rolls inwards, causing the eyelashes or surrounding hair to rub against the surface of the eye. This can cause ongoing irritation and, in some cases, painful corneal ulcers.

Are some dog breeds more prone to entropion?

Yes. Some breeds, including Shar Peis, are more prone to primary or conformational entropion because of their facial conformation and excess skin.

Can a dog develop entropion later in life?

Yes. Secondary or acquired entropion can develop due to eye irritation, trauma or changes to the fat and muscle surrounding the eye.

How is entropion treated in dogs?

Treatment depends on the individual dog. Options can include temporary tacking sutures or permanent surgery. Luna required surgery to remove a small amount of skin and return her lower eyelid to a normal position.

Can entropion surgery need to be performed more than once?

Sometimes. Swelling can make it difficult to judge exactly how much skin needs to be removed, so more than one surgery may be needed to get the correction right.
