Entropion is a turning in of the eyelid. It’s quite dangerous and painful. The eyelids and eyelashes turn in and rub on the cornea. It’s usually a result of shameful breeding practices. There will be discharge because bacteria gets in there and can’t get out. Entropion can cause ulcers. It’s common in short-nosed dogs. Surgery is usually the only answer. Another common type of entropion in dogs is spastic entropion (muscle spasms cause the eyelids to rub against the eye). This type of entropion often correlates to other eye issues, which are typically painful, like a foreign body in the eye or injury or damage to the cornea. Spastic entropion is resolved using topical anesthetics to stop the spasms, followed by treatment of the underlying eye issue that’s causing the spasms.
Some other signs of entropion in dogs include:
In the acquired form, the eyelids roll inward as a result of changes to the eye or the muscles surrounding it. Anything that weakens the eye muscles or shrinks the “globe” of the eye can lead to inward rolling. This occurs as dogs age or develop ophthalmic problems. Conditions such as end-stage glaucoma can also lead to a shrunken globe. Spastic entropion can occur when there is any painful condition (such as a corneal ulcer or uveitis) in the eye. Spastic and acquired entropion can occur in any breed at any age. Inherited entropion is the most well known form. There are many susceptible breeds. Most of them are known for having “extra” skin folds or drooping eyes such as the Shar-Pei and Chow Chow. In these breeds, entropion is generally present at birth.
Eyelid surgery is the only permanent treatment for entropion. An ophthalmologist veterinary surgeon will remove a small piece of tissue directly from below the eyelid and the two sides of the remaining tissue will be pulled together and sutured.
