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.

Özet

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.
