Pet Health Concerns: Entropion

Unlike ectropion, which we wrote about recently, entropion is the inverting of the lower eyelid whereas ectropion is the outward rolling of the eyelid. Entropion is caused by genetic factors that cause the eyelid to roll inward, rubbing on the eye, eventually causing irritation and discomfort to the pet.

Occurring in a variety of cat and dog breeds, entropion symptoms include eye irritation, eye pain, sensitivity to light, and blurred vision if the cornea becomes damaged from the eyelashes rubbing against it. There are several different causes of this condition such as congenital factors which occur when born and acquired entropion occurs secondary to other conditions. Acquired entropion causes blepharospasms which are irregular muscle contractions, which eventually cause inflammation, shifting the eyelid inward.

Persian cat breeds are susceptible to this condition, along with some dog breeds such as the Akita, Shar Pei, Bulldog, Chow Chow, and Mastiff. While simple to diagnose by conducting a physical exam, your veterinarian will take a look at the eyelid to diagnose this condition. Surgery is an available treatment option for pets with entropion, however it may cost several hundred dollars. (See example claim.)

To learn more about the entropion condition, check out our Pet Health Concerns Guide. By enrolling your pet with Trupanion pet insurance, your cat or dog’s policy will include coverage for diagnostic tests, medications, surgeries, hereditary and congenital disorders, as long as treatment for a certain condition is required after enrolling and is not pre-existing.

Has your pet ever experienced any problems with an entropion? If so, we would love to hear from you and any comments, advice, experiences, of thoughts on this condition.
