Abstract

Bu çalışma, 2012-2021 yılları arasında İstanbul Üniversitesi-Cerrahpaşa, Veteriner Fakültesi Cerrahi Anabilim Dalı Kliniği’ne epifora, konjunktival hiperemi ve medial kantusta aniden ortaya çıkan bir kitle varlığı şikâyeti ile getirilen toplam 44 köpeğin değerlendirildiği ilk retrospektif çalışmadır. Getirilen hastaların klinik görünümü, tedavisi ve sonuçları incelenmiştir. Ayrıntılı oftalmolojik muayeneler sonucunda üçüncü göz kapağının kıvrılması ile ilişkili kıkırdağın dışarı dönmesi (16 olgu, 24 göz) ve kıkırdağın dışarı dönmesi ile üçüncü göz kapağı bezinin prolapsusunun (28 olgu, 32 göz) varlığı ortaya çıktı. Kıkırdağın dışarı dönmesi olgularında bozulmuş kıkırdak bölümü uzaklaştırıldı. Kıkırdağın dışarı dönmesine eşlik eden üçüncü göz kapağı bezinin prolapsusu olgularında ise dönen kıkırdağın uzaklaştırılması ile prolabe olan bezin yeniden konumlandırılması için Morgan cep yöntemi uygulandı. Çalışma sonunda elde edilen verilere göre üçüncü göz kapağı ile kıkırdağının dışarı dönmesi ve bu duruma eşlik eden üçüncü göz kapağı bezinin hiperplazisi oluşumunda ırk predispozisyonu, yaş ve cinsiyetin etkisi dikkate alınarak, kullanılan cerrahi yöntemlerin üçüncü göz kapağının fonksiyonunun korunmasında yeterli olduğu belirlendi.

Surgical Treatment of Nictitans Membrane Eversion in Dogs

Abstract

The presented study is the first retrospective evaluation of the scrolling of the third eyelid in a total of 44 dogs referred to the Istanbul University-Cerrahpaşa, Faculty of Veterinary, Department of Surgery between 2012 and 2021 with a sudden onset of an ocular mass in the medial canthus with epiphora and conjunctival hyperemia. The clinical appearance of the patients, the treatment procedures applied, and the results were examined. A complete ophthalmological inspection revealed the cartilage eversion of the nictitating membrane in sixteen patients (24 eyes) due to the scrolling of the third eyelid and cartilage eversion accompanied by a prolapsed gland in twenty-eight patients (32 eyes). Cartilage eversion was treated by the resection of the defected cartilage portion. In cases with prolapse of the nictitans gland accompanying cartilage eversion, the Morgan pocket method was applied to reposition the prolapsed gland by resectioning the rotating cartilage. In conclusion, -taking into account the potential effect of breed, age, and gender predispositions- the therapeutic approach followed revealed satisfactory results in maintaining the functional capacity of the third eyelid in dogs with cartilage eversion of the nictitating membrane and hyperplasia of the nictitans gland.
