Protrusion of the gland is the most common disease of the canine third eyelid and the only acceptable treatment of “cherry eye” is the replacement of the gland in its proper location. The third eyelid gland produce 40% of tears and the excision of this protruded gland can cause a significant decrease in tear production and Schrimer tear test. Several surgical techniques have been developed to replace prolapsed third eyelid glandular tissue with the aim of preserving secretory function. The purpose of this study was to evaluate the Pocket technique in repositioning of the protruded third eyelid gland in dogs. From December 2002 to October 2006, 28 dogs (38 eyes) with protrusion of third eyelid gland were treated by Pocket technique. All of the dogs monitored for at least 6 months. Final outcome of the technique and occurrence of postoperative complications were recorded. One day after surgery the dogs were inspected for corneal ulcer by florescent dyne. Twenty two dogs (79% of all cases) were less than one year of age when prolapse was first noted by the owner. A total of 38 eyes were affected. Ten dogs (35% of all cases) had protrusion of the glands in both eyes .The success rate of surgical replacement was 97% (37 eyes). One gland reprolapsed at a later date. Reprotruded gland was replaced with a second surgery by pocket technique again. Superficial corneal ulcers were seen in two eyes. Epiphora was observed in one case. Sign of mucopurulent discharge after surgery was observed in one dog. Pocket technique does not alter tear production or the morphology of the third eyelid gland ducts. Therefore this procedure can be used on prolapsed third eyelid gland without damaging the gland’s duct system. In this study, no side effects were encountered with this technique. Based on the results of this study it is concluded that Pocket technique can be considered as a reliable procedure for reposition of prolapsed gland of third eyelid.
