Entropion in dogs and cats

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

The condition is usually diagnosed before a puppy’s first birthday. Short-nosed, giant and sporting breeds such as the following are more likely to experience entropion:

  • Mastiffs
  • Great Danes
  • Saint Bernards
  • Bulldogs
  • Chow Chows

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 or being inverted, the following symptoms can accompany entropion:

  • Eye discharge. This can range from clear to yellow-green in colour, and may have a pus-like consistency.
  • Excess tear production. If you notice your pet seems to be ‘crying’ more than usual, it could be a sign that their eyes are being irritated.
  • Squinting. An eye affected by entropion will often appear to have a consistent squint.
  • Eye tics. A twitching eye may be an early sign of entropion.
  • Inflammation. Visible inflammation or sagging around the eye area may be indicative of entropion.

If you notice any issues, you should consult a vet. They will be able to confirm whether your pet has entropion and recommend the best treatment option.

Entropion treatments

Because entropion is caused by physical abnormalities, it usually requires surgery in order to resolve the problem. The surgical process for treating entropion involves reshaping the structure of the eyelids.

The success rate of entropion varies based on breed, age and severity. In general, entropion surgery has a high success rate. Post-surgery, your cat or dog may be required to wear a cone collar around the neck to prevent them from scratching or pawing the affected area.
