What is Entropion in Cats

Entropion in cats is a condition where the eyelid rolls inward, causing the eyelashes and fur to rub against the eye's surface, leading to irritation, pain, and potential corneal damage. It can affect either the upper or lower eyelid.  

Causes of Entropion in cats can be:  

- Genetic  

- Eye infections and inflammations  

- Injury or trauma  

- Age  

- Chronic skin conditions  

- Other diseases

Symptoms of entropion in cats

  • Excessive blinking or squinting  

  • Eye discharge (watery or mucous)  

  • Cloudiness or redness of the eye  

  • Paw or face rubbing around the eye  

  • Sensitivity to light  

  • Corneal ulcers (if left untreated)  

When to contact your vet  

If you notice any signs of entropion in your cat (with the above signs), don't hesitate to contact your vet for an examination and an appropriate treatment plan.  

Diagnosis

  • Examination of the eye  

  • Fluoresceine test is crucial to detect corneal ulcers, the dye adheres to damaged areas, making them visible under a special light.  

  • Schirmer test to quantify tear production. Low tear production could be the reason for pain, inflammation and irritation, leading to entropion  

Treatment of entropion in cats

  • Surgical treatment is required by removing a strip of skin and tissue from the eyelid, which allows it to evert (roll outward) and no longer rub against the cornea  

  • Antibiotics in drops  

  • Painkiller per mouth  

  • Lubricants in the eye  

  • Hyaluronic acid injections - this 'filler' injection can be used as an alternative to surgery, especially for older cats that may not tolerate anesthesia well. It provides temporary support to flip the eyelid outward, though it may require follow-up injections.  

Preventing entropion in cats

Entropion is primarily a genetic or breed-related condition and isn't always preventable. However, some measures can minimise its impact and prevent secondary complications such as:   

  • Regular veterinary check-ups for early detection  

  • Regularly clean your cat's eyes with a damp cloth to remove any dirt or debris that could irritate the eye  

  • Avoid injury such as sharp objects or other cats  

  • Monitor any changes in the eye 

Outlook

The prognosis for cats with entropion, or inward-turning eyelids, is generally good, particularly when diagnosed and treated early. Surgical correction has a high success rate, and most cats recover fully without recurrence. Early treatment is key for a positive outcome.
