In dogs with this condition, the lower eyelid rolls out from the surface of the eye. This exposes the eye to irritants and leads to a high incidence of chronic conjunctivitis and corneal injury. Foreign bodies may get caught in the pocket created by the loose eyelid. Ectropion occurs in dogs with loose facial skin, such as scenthounds, spaniels, and St Bernards. It is also seen in older dogs whose facial skin has lost its tone. It can occur temporarily in hunting dogs, after a long day in the field.
Treatment: Mild ectropion that causes no symptoms needs no treatment. But in most cases, ectropion should be corrected by a surgical procedure that tightens the eyelids.
