Entropion in pets - Diagnosis and treatment

Entropion is an eyelid abnormality in which the eyelid margin rolls inward. As a result, the eyelashes or skin come into contact with the cornea, causing pain, irritation, and eye damage. The condition occurs mainly in dogs but can also affect cats.

In this article, we discuss the causes, symptoms, diagnosis, and treatment options for entropion in pets.

What is entropion?

Entropion means that the eyelid turns inward. This can affect one or both eyes, and either the upper or lower eyelid.

Causes of entropion

• Hereditary predisposition (in certain breeds such as the Shar Pei, Chow Chow, Labrador Retriever, and English Bulldog)
• Excessively loose or overly heavy skin folds around the eyes
• Secondary to scar tissue formation, muscle spasms, or eyelid swelling
• Trauma or chronic eye inflammation
• In cats: British Shorthair and Persian
• At the corner of the eye: Shih Tzu, Pug, French Bulldog, English Bulldog

Symptoms of entropion

• Squinting (blepharospasm)
• Excessive tearing
• Redness and irritation of the white of the eye
• Cloudy cornea or ulcers
• Pain and sensitivity when the eyes are touched

Diagnosis of entropion

The diagnosis is made during an eye examination by the veterinarian. Fluorescein staining can be used to check whether the cornea is damaged. In young animals, improvement can sometimes still occur as they grow.

Treatment of entropion

• Temporary treatment in puppies: temporarily suturing the eyelid ('tacking') to pull it outward.
• Definitive surgical correction: removing a narrow strip of skin along the eyelid so that the eyelid rolls outward again.
• Treatment of secondary problems such as corneal wounds (corneal ulcers) with medication.

Prognosis

The prognosis after surgical correction is usually excellent. In some breeds, a repeat procedure may be necessary.
