The present study was aimed at investigating the pecten oculi of the
ostrich by light and electron microscopy. The pecten oculi of 5 healthy adult
ostriches, obtained from a slaughterhouse, constituted the material of the
study. When examined macroscopically, the pecten oculi of the ostrich was
observed to be a highly pigmented and relatively large fan-like shaped (vaned)
structure consisting of approximately 20-24 folds. It was situated on the
ventral surface of the eye and extended into the vitreous body. Light
microscopic investigation revealed two or more blood vessels and numerous
capillaries in each pecteneal fold. The capillaries had a thick basal lamina
and numerous melanocytes and the pecten was surrounded by the vitreo-pecteneal
limiting membrane. Hyalocytes were not observed outside of the vitreo-pecteneal
membrane. At transmission electron microscopic (TEM) examination, endothelial
cells were observed to possess a thin cytoplasm and the organelles were
localized to the center of the cells. The capillary endothelium exhibited a
large number of luminal and abluminal folds. Pericytes were seen lying beneath
the basal lamina. In the present study, ostrich pecten oculi was examined by
light and electron microscopic and compared with other poultry species and
their differences were revealed.

Yapılan bu araştırmada devekuşu pekten okulisinin ışık ve elektron
mikroskobik olarak incelenmesi amaçlandı. Çalışmada et tüketimine sunulan ve mezbahanede
kesilen 5 adet erişkin ve sağlıklı devekuşundan alınan pekten okuli örnekleri
kullanıldı. Makroskobik incelemeler sonucu, devekuşunda pekten okulinin gözün
ventral yüzeyinden vitreusa doğru uzanan, koyu pigmentli, kendi üzerinde
yaklaşık 20-24 adet kıvrım yapan, oldukça büyük bir yapı olduğu görüldü. Işık
mikroskobik incelemelerde pekten okulinin her bir kıvrımında çok sayıda
kapillar ve melanosit yanında az sayıda arter ve ven de bulunmaktaydı.
Melanositlerin pekten kıvrımlarının perifer kısmında, damarların etrafında
yoğunlaştığı görüldü. Yapının etrafını pekteno-sınırlayıcı membran
çevrelemekteydi. Devekuşu pekten okulisinde hyalositlere rastlanmadı. TEM’de
(Transmission Electron Microscope) endotel hücrelerinin ince stoplazmaya sahip
olduğu ve organellerin hücrenin merkezinde, çekirdek etrafında yer aldığı
gözlendi. Kapillar endotelinin çok sayıda luminal ve abluminal kıvrımı
bulunmaktaydı ve kalın bir bazal laminaya sahipti. Bu laminanın altında ise
perisiler gözlendi. Sunulan çalışmada devekuşu pekten okulisi ışık ve elektron
mikroskobik olarak incelendi ve diğer kanatlı türleriyle karşılaştırılarak
farklılıkları ortaya kondu.
