Issue Description Ectropion is a medical condition in which the
lower eyelid turns outwards. It is one of the notable aspects of
newborns exhibiting Harlequin type ichthyosis. The condition can be
repaired surgically. Ectropion is also found in dogs as a genetic
disorder in certain breeds.

Breeds Prone To Ectropion Ectropion is most commonly seen in dogs with
exaggerated facial features where it is often a breed characteristic.
It is found in the Basset Hound, Bloodhound, Boxer, Bulldog, Bull
Terrier, Clumber Spaniel, English and American Cocker Spaniel, Gordon
Setter, Labrador Retriever, Springer Spaniel, and Shih Tzu.
Ectropion is also common in giant breeds such as the Great Dane,
Mastiff, Saint Bernard, Newfoundland, and Great Pyrenees In these
breeds the central lower lid is often ectropic while the lid at the
corners of the eye is entropic.
Symptoms 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.
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 tear test.
Treatment With mild entropion, no treatment may be
necessary. If secondary problems such as conjunctivitis develop, these
are treated as required. More 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
