Abstract

Corpus vitreum
içerisinde yer alan pecten oculi yüksek damarlaşma ve pigmentasyona sahiptir.
Retinanın beslenmesinde ve hareket eden objelerin iyi görülmesi için yardımcı
bir aygıt olduğundan gündüz avlanan kuşlar için büyük önem taşır. Araştırmada 5
adet ergin erkek bozdoğanın (Falco
columbarius) pecten oculi’sinin morfolojik ve stereolojik incelemeleri
yapılmıştır. Morfolojik
incelemeler sonucu bozdoğan pecten oculi’sinin plikalı tipte ve 17-18 adet
kıvrıma sahip olduğu, şeklinin çeşitkenar yamuğa benzediği saptandı. Bu yapıların ortalama uzunlukları ise 12.26
± 0,21 mm (bazal), 7.97 ± 0,08 mm (apikal), 5.83 mm  ± 0,12 (bazal-apikal arası) olarak tespit edildi. Stereolojik hacmi ise
ortalama 17.28 ± 0,28 mm³ olarak tespit edilmiştir. Bozdoğanda pecten
oculi’nin morfolojik yapısı ortaya konarak stereolojik metotla hacmi
hesaplanmış olup, tür ayrımında birçok çalışmaya kaynak olabileceği düşünüldü.

Morphology and Volume Measurement of Pecten Oculi by Stereology in Merlin (Falco columbarius)

Abstract

Pecten oculi seeded
in corpus vitreum poses high vascularisation and pigmentation. It very
important for day-time hunter birds because it is involved in retinal nutrition
and contributes for better vision to moving objects. In this study, morphologic
and stereologic evaluation of pecten oculi in 5 Merlin (Falco columbarius) was carried out. It was observed that pecten
oculi of merlin was plicated type with 17-18 convulations and resembled scalene
trapezium in shape. Average lenght of these structures were 12.26 ± 0,21 (basal), 7.97 ± 0,08 mm (apical) and, 5.83 mm  ± 0,12
(basal and apical intermission). The avarage stereological volume was 17.28
± 0,28 mm³. It was concluded that morphology and
the volume of pecten oculi by stereological approach were determined and the
data generated here may be useful for the differentiation of species.
