NICTITANS GLAND PROTRUSION
(Cherry Eye, 3rd Eyelid Gland Protrusion)

General Information:
(With thanks to Marilyn for her help on this)

The third eyelid (membrana nictitans) lies between the lower eyelid and the eyeball at the inside corner of each eye. Its purpose is to protect the eye and to help contain and spread tears over the cornea. The third eyelid also contains tear-producing glands and therefore contributes to the overall lubrication of the eye.

The gland of the third eyelid lies within the substance of the third eyelid and occasionally protrudes over the free edge of the third eyelid. As a result, the exposed, sensitive tissue becomes very irritated and inflamed, causing considerable discomfort. The reddened, swollen tissue resembles a cherry; hence, the common name of this condition is "cherry eye." One or both eyes may be affected. Often one eye will be affected then the other will become inflamed at a later date. This condition is very commonly seen in Cocker Spaniels, English Bulldogs, and small breeds like Shih Tzus and Lhasa Apsos, etc.

Treatment Information:

  1. Use of medication alone often fails to alleviate the condition. Surgery is usually required for correction. There are two procedures currently used: 

    1. Gland Excision:
      This involves removal of the gland. While it is the quickest and most inexpensive procedure, studies indicate that it may predispose individual patients to develop Keratoconjunctivitis sicca (KCS or "Dry Eye") in later life.

    2. Gland Replacement:
      This involves replacing the gland into the eyelid.

  2. After the surgery, your pet will be discharged with ophthalmic ointment(s). These are to be applied to the affected eye 2 -3 times daily for 10 days.

  3. If Gland Excision is performed, no recheck is necessary after surgery unless there is problem. No sutures were used during the procedure.
    If Gland Replacement is performed, your veterinarian will schedule at least one recheck for eyelid suture removal.

We hope that you will find this information helpful in your quest for better pet care. If you have any questions or comments, please call your veterinarian's office, or feel free to e-mail us.
