Entropion is a genetic condition where part of the eyelid becomes folded inwards or inverted, causing irritation to the surface of the eye (cornea). If left untreated, it could cause scar tissue to build up over any corneal wounds, known as pigmentary keratitis.

In pets, entropion is usually diagnosed before a dog or cat’s first birthday. Short-nosed, giant and sporting breeds of dogs, such as Mastiffs, Great Danes, Saint Bernards, Bulldogs and Chow Chows, are more likely to experience this condition. Though not quite as common as dogs, entropion can also be found in cats.

Signs and symptoms of entropion

As well as the eyelid folding inwards, the following symptoms can accompany entropion:

  • Eye discharge ranging from clear to yellow-green in colour
  • Excess tear production
  • Squinting
  • Eye tics (twitching)
  • Inflammation around the eye

If you notice any of these symptoms in your furry friend, you should consult a vet. They will be able to confirm whether your pet has entropion and recommend the best treatment option.

Entropion treatments for your pet

Because entropion is caused by physical abnormalities, it usually requires surgery to resolve the issue. The surgical process for treating entropion involves reshaping the structure of the eyelids. In general, entropion surgery has a high success rate. Post-surgery, your pet may be required to wear a cone collar around the neck to prevent them from scratching or pawing the affected area.
