This study aimed to investigate the macroscopic, light microscopic (LM) and scanning electron microscopic (SEM) characteristics of the pecten oculi in common kestrels (Falco tinnunculus). A total of six eyeballs from three common kestrels were used as the study material. The examination revealed that the bulbus oculi was spherical in shape and its diameter exceeded the axial-global length. In the equatorial section of the eyeball, the pecten oculi were observed to be situated on the retina layer where the optic nerve enters the eyeball, showing a posterior-to-anterior distribution. The pecten oculi appeared dark brown, with a convoluted structure, comprising approximately 15-17 vascular folds. Scanning electron microscopic examination revealed dense capillary vascular folds on the surface of the pecten oculi. Within these capillary vessels, a few hyalocytes were noted, and melanocytes were found at the edges of the folds. Light microscopic examination detected numerous large, medium and small diameter vessels within the folds of the pecten oculi, especially at the periphery of the folds and the apical parts of the pecten oculi. The findings of this study were compared with the morphological characteristics of the pecten oculi in other bird species, revealing both similarities and differences.
本研究旨在调查普通红隼（Falco tinnunculus）眼梳膜的大体、光学显微镜（LM）和扫描电子显微镜（SEM）特征。以三只普通红隼的六个眼球作为研究材料。检查发现眼球呈球形，其直径超过轴长。在眼球的赤道切面中，观察到眼梳膜位于视神经进入眼球处的视网膜层上，呈后向前分布。眼梳膜呈深褐色，结构复杂，约有15 - 17个血管褶。扫描电子显微镜检查显示眼梳膜表面有密集的毛细血管褶。在这些毛细血管内，发现了一些透明细胞，并且在褶的边缘发现了黑素细胞。光学显微镜检查在眼梳膜的褶内检测到大量大、中、小直径的血管，尤其是在褶的周边和眼梳膜的顶端部分。本研究结果与其他鸟类物种眼梳膜的形态特征进行了比较，揭示了异同点。
