Evaluation of the Differences in Parameters Obtained from the Computed Tomography Images of the Eyeball and the Structures in the Orbit by Age and Gender

Abstract

Objective: The aim of this study is to show the variation of eyeball and orbital structures according to different age groups and gender. Methods: The study was conducted on computerized tomography (CT) images of 4 age groups: 30-40, 41-50, 51-60, and over 61 years old. The parameters were, the angle between the optic nerve and axis of eyeball (A-Cr2AA), the length of the medial rectus muscle (MRML) and the length of the lateral rectus muscle (LRML) up to the Zinn ring, the thickness of the lens (LT), the length of the optic nerve from the Zinn ring (Cr2L), optic nerve thickness (Cr2T), distance between two eyeballs (BOD) and the others. Results: As a result of the study, in the comparison of males in four groups, significant difference was found between the groups in LT, Cr2L, A-Cr2AA, MRML parameters in the right eyeball and Cr2L and LRML parameters in the left eyeball (p<0.05). In the comparison of females in four groups, significant difference was found between the groups in BOD, LT, Cr2L, LRML, MRML in the right and left eyeball and Cr2T parameter in the left eyeball (p<0.05). Conclusion: As a result of the study, it was determined that age and gender differed in the determined parameters.

Göz Küresi ve Orbitadaki Yapıların Bilgisayarlı Tomografi Görüntülerinden Elde Edilen Parametrelerdeki Farklılıkların Yaş ve Cinsiyete Göre Değerlendirilmesi

Abstract

Amaç: Bu çalışmanın amacı göz küresi ve yörünge yapılarının farklı yaş gruplarına ve cinsiyete göre değişimini ortaya koymaktır. Gereç ve Yöntem: Çalışma 30-40, 41-50, 51-60, 61 yaş üzeri 4 yaş grubuna ait bilgisayarlı tomografi (BT) görüntüleri üzerinden gerçekleştirildi. Parametreler, optik sinir ile göz küresi ekseni arasındaki açı (A-Cr2AA), medial rektus kasının uzunluğu (MRML) ve lateral rektus kasının uzunluğu (LRML) Zinn halkasına kadar, lensin kalınlığı (LT), optik sinirin Zinn halkasından itibaren uzunluğu (Cr2L), optik sinir kalınlığı (Cr2T), iki göz küresi arasındaki mesafe (BOD) ve diğerleri idi. Bulgular: Çalışma sonucunda erkeklerde dört grup karşılaştırıldığında, sağ göz küresinde LT, Cr2L, A-Cr2AA, MRML parametreleri ile sol göz küresinde Cr2L ve LRML parametrelerinde gruplar arasında anlamlı fark bulundu (p< 0,05). Kadınlarda dört grup karşılaştırıldığında sağ ve sol göz küresinde BOD, LT, Cr2L, LRML, MRML ve sol göz küresinde Cr2T parametresinde gruplar arasında anlamlı fark bulundu (p<0,05). Sonuç: Araştırma sonucunda belirlenen parametrelerde yaş ve cinsiyetin farklılık gösterdiği belirlendi.
