Entropion

Symptoms of Entropion

The most common signs associated with entropion are excessive tearing, squinting and pain. Symptoms that owners may notice include:

  • Watery eyes; tearing (excessive lacrimation)
  • Ocular discharge; can be thick, gummy and contain blood or pus
  • Squinting
  • Eye redness
  • Eyelid twitching (blepharospasm)
  • Visible inrolling of the upper and/or lower eyelids
  • Thick, “heavy” skin around the eyes
  • Eyelid swelling
  • Difficulty opening the eyes, especially in sunlight
  • Pain
  • Depression (due to pain)
  • Lethargy (due to pain)
  • Aggression (due to pain)
  • Corneal ulceration or erosion
  • Corneal rupture
  • Rubbing at the eyes; self-trauma (due to pain)

Signs of entropion usually – but not always - occur in both eyes. If the cause is genetic, clinical signs will be apparent early in life and can be seen even in puppies that are only a few weeks old. In fact, novice breeders of affected breeds (especially Chows and Shar-peis) may think that their puppies’ eyes have not opened by 4 or even 5 weeks of age, when in reality the puppies’ eyes opened normally, but severe congenital entropion is present.

Dogs at Increased Risk

There is no gender predisposition to this disorder. However, there is a definite genetic predisposition in certain breeds, although the mode of inheritance is not well understood. Affected breeds include the Chow Chow, Shar-Pei, Norwegian Elkhound, Boxer, Rottweiler, Doberman Pinscher, Labrador Retriever, Cavalier King Charles Spaniel, Cocker Spaniel, Springer Spaniel, Irish Setter, Elkhound, Bull Terrier, Collie, Shetland Sheepdog, Bloodhound, Clumber Spaniel, Maltese, certain other sporting and hunting breeds (Pointers, Retrievers, Spaniels), brachycephalic breeds (English Bulldogs, Pugs, Pekingese), toy breeds (Miniature and Toy Poodles, Yorkshire Terriers) and certain giant breeds (Mastiffs, Bull Mastiffs, St. Bernards, Newfoundlands, Great Pyrenees, Great Danes).
