Entropion in dogs
Entropion has been documented in most
dog breeds, although there are
some breeds (particularly
purebreds) that are more commonly affected than others. These include the
and Poodle. The condition
is usually present by six months of age. Entropion can also occur secondary to
pain in the eye, scarring of the
eyelid, or nerve damage. The upper or lower eyelid can be involved. Upper lid
entropion involves the
eyelashes rubbing on the eye, but the lower lid usually has no eyelashes, so
hair rubs on the eye.
Surgical correction is used in more severe cases. A strip of skin and
orbicularis oculi muscle are removed parallel to the affected portion of the
lid and then the skin is
sutured. Shar Peis,
who often are affected as young as two or three weeks old, respond well to
temporary eyelid tacking. The entropion is often corrected after three to four
weeks, and the sutures are removed.
