Eversion of third eyelid and its correction using microsurgery

Abstract

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, Newfoundalnder, 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 conjunctive. 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. .

Everzija trećeg očnog kapka - EPT predstavlja izvrtanje dela trećeg očnog kapka, odnosno njegove margine anteriorno. Skoro isključivo se javlja kod velikih rasa pasa kao što su: nemački ovčar, doga, bernandinac, njufaundlend, retriveri i engleski buldog. Kao osnovni razlog nastanka EPT smatra se urođena ili stečena slabost hrskavice PT. Klinička slika je raznolika i najčešće zavisi od intenziteta, trajanja i mogućih komplikacija. Najmarkantniji znak je određen stepen EPT-a. Terapija se bazira na pažljivoj submukoznoj eksciziji deformisane hrskavice, sa opcionim ušivanjem konjunktive. Najčešća komplikacija je ponovna everzija kapka, kao i protruzija žlezde PT. Prognoza je dobra ako su preoperativna i operativna procedura odgovarajuće sprovedene, a kapak nije prevelike dužine. .
