Cherry Eye

A cherry eye is a prolapse of the gland of the third eyelid. In some cases the cherry eye can be associated with eversion of the third eyelid cartilage.

The cause of the condition is unknown but is common in certain breeds, and may follow trauma to the eye. It seems to be common in younger dogs.

It is possible for the problem to develop in both eyes, although the other eye can develop the problem sometime after the cherry eye initially presents.

Breeds predisposed include Basset Hounds, Sharpeis, Maltese Terriers, Beagles, Bulldogs, Cocker Spaniels, and Rottweilers. The inheritance of the condition is unknown.

Possible problems caused by the prolapsed gland can include enlargement of the gland which can cause conjunctivitis and even ulceration to the eye.

Treatment

Medical therapy i.e. drops & ointments are rarely effective. Surgery is indicated to permanently replace the gland.

Excising the gland is not recommended as this may cause dry eye. The gland may produce between 30 to 60% of the tears that protect the eyeball.

The gland is stitched back into place underneath the eye. This requires a general anaesthetic and half a day in hospital. After surgery the third eyelid may sit across the eye for 3 to 7 days.

We find that in most cases there is very little swelling or postoperative discomfort after the surgery. In some breeds especially the Basset Hound the third eyelid may be too large, and it may be necessary to remodel the third eyelid.

In some cases this may not become apparent after the swelling related to the cherry eye and the surgery resolves. The most common problem we have is eversion of the third eyelid cartilage.

In a small number of cases the suture that is used may break or pull through. More surgery will then be required. This happens in less than 2% of cases.
