Farklı Kanatlı Türlerine Ait Pekten Okuliler Üzerine Karşılaştırmalı Histolojik Çalışma

Abstract: Tüm vertebralılardan farklı olarak kanatlı retinası tamamen avaskülerdir (1). Retina pekten okuli olarak adlandırılan ve yalnızca kanatlı gözünde bulunan bir yapı tarafından beslenir Pektenin retinayı beslenme dışında birçok farklı fonksiyonu da bulunduğu düşünülmektedir (2).Morfolojik olarak, pekten okuli koni tipi (Kiwi) pervane tipi (devekuşu) pili tipi (diğer tüm kuş türleri) olmak üzere üç sınıfa ayrılmıştır (3). Temelde üç sınıfa ayrılsalar da her kanatlı türünde farklı büyüklüklerde ve farklı sayıda pil… Show more

“…It was observed that there were significant differences among species in the number of pleats forming pecten oculi. A large number of pleats were found in birds such as ostrich (Korkmaz & Harem, 2021;20-24 pleats), American crow (Braekevelt, 1994;22-25 pleats) and Australian galah (Breakevelt & Richardson, 1996;20-25 pleats), while the birds such as the Barred owl (Smith et al, 1996;8-10 pleats), duck (Moselhy & El-Hady, 2019;10-14 pleats), and Black kite (Kiama et al, 1994;12 pleats) had few pleats. As a result of the present comparative study, the number of pleats in sparrow, hawk, magpie, swan, heron, pheasant and duck was determined to be 14-16, 15-17, 27-30, 10, 11-12, 20-21 and 12, respectively. When the study results were examined, the magpie, a small bird from the Corvidae family and included in the Pica pica family (Kaplan, 2019), had a small eye.…”

“…The intraocular structure of birds differs anatomically from that of mammals (Reese et al, 2009). Avian ocular anatomy shows many polymorphisms in itself; one of the anatomical formations in which this polymorphism appears is the pecten oculi (Dayan & Ozaydin, 2013; Korkmaz & Harem, 2021). The pecten oculi is an organ found only in the eyes of birds that extends from the retinal entrance of the optic nerve towards the vitreous body (Ince et al, 2017; Yilmaz et al, 2017).…”
