Third eyelid scrolling and surgical treatment - a case report

This report describes the clinical presentation, treatment, and outcome of a dog with third eyelid scrolling associated with prolapse of the gland of the third eyelid, which was treated with a modified surgical technique, and determines whether this procedure preserves the functions of the third eyelid, reduces cartilage shortening, eliminates the recurrence and finally improves the vision. An 8-month-old male German shepherd dog was presented with ocular irritation and epiphora. Ophthalmic examination revealed an everted third eyelid associated with a prolapsed nictitans gland. We performed the Morgan pocket technique to reposition the prolapsed gland in the current case, and the incision of deformed cartilage was done simultaneously. The surgical outcome was excellent with no recurrence or other complications. The Morgan pocket technique is a suitable surgical technique, however we corrected eversion of third eyelid by cutting the central portion of the deformed cartilage rather than removing the whole or part of it. This work may provide an alternative surgical treatment of third eyelid scrolling in dog.
