One crucial component of the optical system is the ciliary body (CB). This body secretes the aqueous humour, which is essential to maintain the internal eye pressure as well as the clearness of the lens and cornea. The histological study was designed to provide the morphological differences of CB and iris in the anterior eye chambers of the following vertebrate classes: fish (grass carp), amphibians (Arabian toad), reptiles (semiaquatic turtle, fan-footed gecko, ocellated skink, Egyptian spiny-tailed lizard, Arabian horned viper), birds (common pigeon, common quail, common kestrel), and mammals (BALB/c mouse, rabbit, golden hamster, desert hedgehog, lesser Egyptian jerboa, Egyptian fruit bat). The results showed distinct morphological appearances of the CB and iris in each species, ranging from fish to mammals. The present comparative study concluded that the morphological structure of the CB and iris is the adaptation of species to either their lifestyle or survival in specific habitats.
眼的光学系统的一个重要组成部分是睫状体（CB）。该体分泌房水，这是维持眼内压以及晶状体和角膜清晰度所必需的。这项组织学研究旨在提供以下脊椎动物类别的眼前房的 CB 和虹膜的形态差异：鱼类（草鱼）、两栖类（阿拉伯蟾蜍）、爬行类（半水生龟、扇足壁虎、豹纹守宫、埃及刺尾蜥、阿拉伯角蝰）、鸟类（普通鸽子、普通鹌鹑、普通红隼）和哺乳动物（BALB/c 小鼠、兔子、金黄仓鼠、沙漠刺猬、小埃及跳鼠、埃及果蝠）。结果表明，从鱼类到哺乳动物，每种物种的 CB 和虹膜都有明显的形态外观。本比较研究得出的结论是，CB 和虹膜的形态结构是物种适应其生活方式或在特定栖息地生存的结果。
