Entropion
Entropion is an ophthalmic condition in which the eyelids roll inward, allowing lashes and hair to irritate the surface of the eyes. The condition is inheritable, or it can occur secondary to other types of eye irritation (spastic entropion) or eyelid injury. Congenital entropion has a high incidence in chow chows, shar-peis, English bulldogs, poodles, and rottweilers.
Signs of entropion include excessive tearing, squinting, constant rubbing of the affected eye(s), excessive redness to the eye(s), and a noticeable inward roll to the eyelid, especially the lower lid.
If a pet is suffering from entropion, surgical treatment might be essential to prevent lasting damage to the surface of the eye(s). Some puppies afflicted with this disorder might outgrow it as they mature; hence, surgery is usually delayed in these young animals until they are at least 6 months old, unless the damage to the eye is severe.
In the meantime, topical lubricants designed to protect the corneas can be used on a daily basis in these patients. In some pups, especially sharpeis, temporary eversion of the offending lids with sutures implanted in the skin of the lids can also help prevent complications until they outgrow the entropion or are old enough for the surgery.
Entropion surgery involves the removal of a flap of skin just beneath (lower lid) or above (upper lid) the inverted lid. Suturing close the resulting gap of skin will then provide enough tension to roll the lid back out. In many instances, more than one surgery is necessary to achieve just the right amount of eversion.
After surgery is performed, care must be taken to prevent the dog from irritating the incision line and causing swelling. Hospitalization for a few days after the procedure is performed will help reduce this occurrence.
Because of the inheritable nature of this disorder, all dogs affected with entropion should be neutered to prevent its passing to future generations. When selecting a new pet, especially one that falls into the high-risk category, owners should examine the pup’s parents closely for any signs of entropion or for evidence that surgical correction has been previously performed.
Ectropion
Ectropion is the exact opposite of entropion; it is the outward rolling of the eyelid(s), which exposes the pink conjunctival lining within. As with entropion, this condition is inheritable, with cocker spaniels, St. Bernards, and bloodhounds having a high incidence. Facial nerve paralysis, such as that seen secondary to otitis media, can also result in ectropic lids.
Mild cases of ectropion usually cause no problems whatsoever in affected individuals. Moderate to severe cases are often accompanied by conjunctivitis, excessive lacrimation, and eye discharges. Keeping the eye(s) clean and free of discharge on a daily basis using saline solution or medicated drops or ointments will help keep minor cases of ectropion under control. For more extensive involvement, surgical correction designed to release the tension placed on the skin of the eyelid, allowing it to roll back to its correct position, might be required.
