The present study was carried out to investigate the morphological and histomorphometric characters of choroid in donkeys, buffalos, camels and dogs.
The findings of the study revealed that, macroscopically, the choroid was consisted of two areas in all studied animals, except in camel which consists of one area. Histologically, the choroid consists of five layers. Interestingly, the anterior borders of all investigated animals were free of pigments except in camel. Morphometric analysis revealed significant species differences in the mean total thickness of the choroid and its different layers. In addition, significant differences were also found between the ratios of the means of different layers to the total thickness of the choroid.
In conclusion, these variations might be related to the different lifestyles and visual behavior of the investigated animals.
本研究旨在调查驴、水牛、骆驼和狗脉络膜的形态学和组织形态计量学特征。
研究结果显示，在宏观层面上，除骆驼只有一个区域外，所有被研究动物的脉络膜均由两个区域组成。在组织学上，脉络膜由五层组成。有趣的是，除骆驼外，所有被调查动物的前缘均无色素。形态计量分析显示，脉络膜及其不同层的平均总厚度存在显著的物种差异。此外，不同层的平均值与脉络膜总厚度的比值之间也存在显著差异。
总之，这些差异可能与被调查动物不同的生活方式和视觉行为有关。
