Prolapso de la glándula del tercer párpado en canino mestizo, tratado quirúrgicamente mediante la técnica de Morgan combinada y anclaje de la glándula al periostio orbital.

Abstract

The protrusion or eversion of this gland of the nictitating membrane is called “cherry eye” and is the most frequent veterinary ophthalmological condition, whether unilateral or bilateral, caused by an enlargement of the gland due to an incomplete development of the ligaments that support the base of this against the periorbital tissue, which allows it to externalize and expose itself to the environment. It can also have a genetic origin causing alterations in the anchoring system of the third eyelid to the ocular orbit, which is very common in canines with a higher predisposition in those of small breeds (Cocker Spaniel, Beagle, English Bulldog, French poodle) , among which the brachycephalics also stand out. Specifically, in this clinical case, a 5-month-old mixed breed canine patient with a history of loss of appetite, decay and exposure of the third eyelid gland in the left eye was treated. The patient was evaluated and entered for observation in order to perform the surgical treatment. He underwent a clinical examination, pre-surgical tests that included a blood count and blood biochemistry showing mild lymphocytosis, possibly post-vaccination, and without any other clinically important alteration. Surgical treatment was then carried out using the modified Morgan technique and the attachment to the periosteum of the orbital edge, at the level of the lacrimal bone. The patient evolved favorably and was discharged after the second postoperative evaluation carried out 15 days after the procedure.
