Marsupialization of a cyst of the nictitating membrane in three dogs.

Marsupialization appears to be a safe, simple, and effective treatment for nictitating membrane cyst secondary to surgical correction of gland prolapse using conjunctival pocket technique in dogs. Further studies on a larger number of cases are necessary to determine whether marsupialization is the technique of choice and to further investigate the pathophysiology of cyst formation after conjunctival pocket repositioning of prolapsed glands.
