One or both eyes may be involved. It can occur in any breed, but it is inherited in American Cocker Spaniels, Saint Bernards, Mastiffs and Bloodhounds. As the lower lid sags downward, the underlying conjunctiva is exposed. This forms a pouch or pocket, allowing pollens, grasses, dust, etc., to accumulate and rub against the sensitive conjunctiva. This is a consistent source of irritation in these dogs, leading to increased redness of the conjunctiva and occasional watering of the eye which then spills out over the lower lid and face.
Many dogs live normal lives with ectropion.
However, some develop repeated eye infections due to the collection of dirt, dust, etc., within the eye. Therefore, the risks are minor except in severe cases, where secondary eye infections may develop. In severe cases a surgical procedure is preferred which removes excess tissue , thereby tightening the lids and removing the abnormal pocket. Inc. All rights reserved.
