Abstract

This study was conducted to obtain the morphometric and volumetric measurements of bulbus oculi of Van cats, growing around the city of Van in Turkey and named after here, by using computed tomography (CT) and magnetic resonance imaging (MRI), and to reveal the biometric differences of these measurement values between the sexes. A total of 16 adult Van cats including 8 females and 8 males were used in the study. The animals were anesthetized with the combination of xylazine and ketamine. The anesthetized animals were scanned by using CT and MRI devices and their images were obtained. Then, the morphometric and volumetric measurements of bulbus oculi were calculated from these images using the software (Syngo CT Software) in the workstation and their statistical analysis was performed. Upon the examination of the morphometric and volumetric analysis results, it was determined that while W (bodyweight) and ACL (Left Anterior Chamber) values were higher in male cats, DVLL (Dorsoventral length of the left lens) value was higher in female cats. These differences between the sexes were statistically significant (P

Özet

Bu çalışma, Türkiye’de Van ili yöresinde yetiştirilen ve ismini buradan alan Van kedilerinde bulbus oculi’nin bilgisayarlı tomografi (BT) ve manyetik rezonans görüntüleme (MRG) ile morfometrik ve volümetrik ölçülerini elde etmek ve bu ölçüm değerlerinin cinsiyetler arasındaki biyometrik farklılıklarını ortaya koymak amacıyla yapıldı. Çalışmada 8 dişi, 8 erkek olmak üzere toplam 16 adet erişkin Van Kedisi kullanıldı. Hayvanlar ketamin-ksilazin kombinasyonu ile anesteziye alındı. Anestezi altındaki hayvanlar BT ve MRG cihazı ile taranarak görüntüleri elde edildi. Daha sonra bu görüntülerden iş istasyonundaki yazılım programı (Syngo CT Software) kullanılarak bulbus oculi’nin morfometrik ve volümetrik ölçümleri hesaplandı ve istatistiki analizi yapıldı. Morfometrik ve volümetrik analiz sonuçlarına bakıldığında, W (vücut ağırlığı) ve ACL (sol ön kamera) değerlerinin erkek kedilerde; DVLL (sol lens’in dorsoventral uzunluğu) değerinin ise dişi kedilerde daha yüksek olduğu tespit edildi. Cinsiyetler arasındaki bu farkların istatistik olarak önemli düzeyde olduğu gözlendi (P
