In dogs
Ectropion in dogs usually involves the lower eyelid. Often the condition has no symptoms, but tearing and
conjunctivitis may be seen. Breeds associated with ectropion include the Saint Bernard, the
Bloodhound, the
Clumber Spaniel, Newfoundlands, and the Neapolitan Mastiff.
It can also result from
Physical trauma or nerve damage. Treatment (surgery) is recommended only if there is chronic conjunctivitis or if there is
damage. A small part of the affected lid is removed and then the lid is sewn back together.
