Eversion of third eyelid and its correction using microsurgery

Eversion of the third eyelid - EPT, is a condition when the third eyelid rolls back, actually of its margin anteriorally. It occurs almost exclusively in big dog breeds such as the German shepherd, doga, St. Bernard, Newfoundlander, retrievers, and English bulldogs. Congenital or acquired weakness of the PT cartilage is considered as the main reason for the incidence of EPT. The clinical picture is diverse and it most often depends on the intensity, duration and possible complications. The most prominent sign is a certain degree of EPT. Therapy is based on careful submucous excision of the deformed cartilage, with optional stitching of the conjuctive. The most frequent complication is a repeated eversion of the eyelid, as well as protrusion of the PT gland. The prognosis is good if the preoperative and operative procedure are carried out as required and the eyelid is not too long.
