Cherry Eye treatment

Veterinary Vision: Public Forum *Cherry Eye*: "'Cherry eye' is the term often used to describe protrusion of the tear gland associated with the third eyelid membrane in the corner of the eye. This occurs due to weakness in the gland's normal attachments and is thought to be an inherited abnormality in several breeds of dogs, including the English Bulldog, Cocker Spaniel, Lhasa Apso, and Shar Pei. It is also seen in Burmese cats where it may be related to abnormalities in the membrane itself as well as the gland. 'Cherry eye' often affects both eyes although the second gland may prolapse several months after the first.
Treatment for this condition involves surgically replacing the gland into its normal position and attaching it with sutures. This gland is responsible for producing approximately a third of the tear volume to the surface of the eye. Thus, removal of the gland is not recommended as this can compromise tear function and can lead to development of 'dry eye' later in life.
Surgery for this condition is done under general anesthesia. Your pet is able to go home the same afternoon. There may be some swelling and redness of the eye which will resolve over the first 3-5 days. Surgery is most likely to be successful if it is done soon after the gland prolapses. With time, prolonged swelling of the gland can make repositioning more difficult and recurrence more likely.

Cherry Eye in English Bulldogs

Cherry Eye in Dogs: "The medical term for 'cherry eye' is nictitans gland prolapse, or prolapse of the gland of the third eyelid. Unlike people, dogs have a 'third eyelid' that contains a tear gland and is located in the corner of each eye. Under normal circumstances, this gland is not visible and aids in the production of tears. For some reason, which is not completely understood, the gland of the third eyelid prolapses or comes out of its normal position and swells creating the condition known as cherry eye.
What dogs are likely to get cherry eye?
Any dog can develop cherry eye, but there are several breeds that appear to have a higher incidence of developing it in both eyes. They are: the Beagle, Bloodhound, Boston Terrier, Bulldog, Bull Terrier, Lhasa Apso, Saint Bernard, and Shar-Pei. Dogs can acquire this condition at any age and it affects males and females equally.
What causes it?
The exact cause of cherry eye is not known, but it is strongly suspected that it is due to a weakness of the connective tissue that attaches the gland to the surrounding structures of the eye. The weakness of the connective tissue allows the gland to prolapse. Once the gland prolapses and is exposed to the dry air and irritants, it can become infected and/or begin to swell. The gland often becomes irritated, red, and swollen. There is sometimes a mucous discharge and if the animals rub or scratch at it, they can traumatize the gland further or possibly create an ulcer on the surface of the eye.
What is the treatment?
Treatment of cherry eye is very straightforward and consists of surgically repositioning the gland. Topical or injectable treatments of antibiotics and steroids are rarely effective in reducing the gland and allowing for correction without surgery. Because the exposed gland is at greater risk for
