Ectropion

Ectropion is outward rolling of the eyelid away from the ocular surface, exposing the eye to adverse environmental influences and often resulting in keratoconjunctivitis. Bloodhounds, Newfoundlands, Cocker Spaniels, Bulldogs, and Retrievers are among the breeds predisposed to ectropion because of their anatomical characteristics. Ectropion may also develop after eyelid injury and scar formation. It is often observed in dogs in which surgical correction of entropion has been excessive. Paralytic ectropion can also occur as a result of facial nerve paralysis.

Treatment

If ectropion causes clinical problems, it is permanently corrected surgically in dogs older than six months.
