Entropion by Leanne Gosset         Entropion is a common congenital defect of the eyelids. Sometimes entropion may be caused by dust or debris collecting in the eye, by eyelashes growing in the wrong direction, or by an eye injury.  Entropion is the term given to the overall condition when the lower eyelid inrolls, bringing the eyelashes into direct contact with the cornea.  This contact creates an irritation, making it necessary for the animal to blink constantly.  As the animal blinks, it is compounding the problem by scraping the eyelashes across a more extensive area of the eye.
        In breeds with large heads and loose facial skin, entropion can be found in the upper eyelids as well.
         The entropion can also be complicated by blepharospasm.  Blepharospasm is when the muscles around the eye spasms, causing severe squinting.  Blepharospasm can be relieved by the application of anesthetic drops but the relief is temporary unless the factors causing the spasms has been removed.
        Entropion should never be left to take care of itself.  If left untreated, the condition could cause sore watery eyes, infection, ulcers on the cornea and even blindness.  Entropion condition requires surgical correction by a veterinarian.
