Entropion is a disorder in which the lower lid margins roll inward to the extent that hair rubs on the plane of the eyeball. In rare cases, the upper lid can also be affected to some degree. One or both eyes may be involved. This condition can occur in all breeds, frequent recurrence
to some breeds suggesting an inherited trait.
Most dogs with entropion will squint and have a reddened, irritated and swollen eye. Because of the pain suffered
, dogs will scratch at the eye with a paw, probably doing further injuries. Examination of the lower eyelid will verify the diagnosis.
Left untreated, severe eye problems
may extend. The cornea can develop into severely irritated or damaged as the chronic abrasion by the inverted lower lid wears away at its surface. In some cases, deep ulcers form in the cornea, even to the point of bursting through its surface. This rapidly leads to intra ocular disease and possible blindness.
Once diagnosed, surgery is the only cure. There are several diverse techniques, but classically, a tiny incision is made below the lid, a little portion of skin is detached, and when the two sides of the incision are then sutured, it drags the border of the lid downward into a regular position. Antibiotic treatments
may be applied, if infections are present.
