Canine Disease Information: Ectropion



  • Type Disease
    Eye
  • Name
    Ectropion
  • Abbreviation
    ECTP
  • Description
    Ectropion is a defect of conformation in which there is a sagging or rolling-out (eversion) of the eyelids. This results in abnormal exposure of the eye, which often leads to irritation.
  • How Transferred
    It is likely that Ectropion is influenced by several genes (polygenic inheritance) that affect the skin and other structures that make up the eyelids, and that affect the way the skin covers the face and head.
  • What to Look for
    Because of increased exposure of the eye, dogs with ectropion are prone to develop allergic or bacterial conjunctivitis - inflammation of the thin membrane which covers the periphery of the surface of the eye and lines the eyelids. Affected dogs may develop keratoconjunctivitis sicca because of reduced efficiency at wetting and cleaning the cornea.\n\nDogs who have had surgical correction for a defect such as Ectropion are prohibited from exhibition in the show ring.\n\n
  • Diagnosis
    In addition to the sagging of the eyelids, dogs with Ectropion commonly have a mucopurulent discharge in the eye, reddening of the exposed conjunctiva, and decreased tear production. To check the latter, your veterinarian will do a Schirmer's tear test.
  • Treatment
    With mild Ectropion, no treatment may be necessary. If secondary problems such as conjunctivitis develop, these are treated as required.\n\nMore severe Ectropion can lead to chronic problems associated with eye irritation. In these cases, surgery is performed to remove a small wedge of tissue from the margin of the eyelid.
  • Breeding Considerations
    With mild Ectropion, no treatment may be necessary. If secondary problems such as conjunctivitis develop, these are treated as required.\n\nMore severe Ectropion can lead to chronic problems associated with eye irritation. In these cases, surgery is performed to remove a small wedge of tissue from the margin of the eyelid.
