Surgical Reposition of Third Eyelid Gland Prolapse (Cherry Eye) in the Dog

Abstract

Prolapse of third eyelid gland, cherry eye, is the most common primary disorder of the nictitating membrane in the dog. Traditional surgical removal of the prolapsed third eyelid gland has been performed in Taiwan for many years. However, surgical excision may result in tear production deficiency, which requires life-long medication. We have been using two other surgical techniques to replace prolapsed third eyelid glands and retain their tear-producing functions. These techniques included conjunctival pocket method and orbital rim anchoring procedures. In this article, the outcomes and advantages of the two surgical techniques were described and compared. The conjunctival pocket technique was performed in 5 dogs and orbital rim anchoring procedure in 1 dog. Proper reposition of the third eyelid glands and good cosmetic outcomes obtained with minimal post-operative complications by these 2 techniques. The conjunctival pocket technique was found to be easier to perform in those cases. Based on the outcomes following the reposition techniques and possible complications following surgical excision, the reposition techniques are good options for treatment of the prolapsed third eyelid gland.
