The anterolateral eye, the posterolateral eye and the posteromedial eye of the web-building spider, Argiope amoena have been examined by light and electron microscopy. The dioptric apparatus of all three eyes is similar in structure, and consists of a cornea, a lens and a vitreous body. The retina contains monopolar receptor cells, the cell bodies of which are present beneath the vitreous body in all three eyes. Proximal processes of the receptor cells form rhabdoms beneath the cell body layer and then extend toward the first optic glomerulus as an ocellar nerve. Two distinct patterns of retinal organization are present in the three eyes. In one type the rhabdomic layer of the retina is backed by a pigmented layer. In the other type the rhabdomic layer is backed by a tapetal reflecting layer. Rhabdomic structure and cytoplasmic inclusions of the receptor cells differ greatly between the two types. The anterolateral eye possesses a single type of retina with the rhabdoms backed by the tapetum. Both the posterolateral and the posteromedial eye are similar in structure, each possessing beneath the common dioptric apparatus retinae of both types.
对园蛛科蜘蛛悦目金蛛的前侧眼、后侧眼和后中眼进行了光学显微镜和电子显微镜检查。这三只眼的屈光装置结构相似，均由角膜、晶状体和玻璃体组成。视网膜包含单极感受器细胞，其细胞体在这三只眼中均位于玻璃体下方。感受器细胞的近端突起在细胞体层下方形成视杆，然后作为眼神经向第一视小球延伸。这三只眼中存在两种不同的视网膜组织模式。在一种类型中，视网膜的视杆层由色素层支持。在另一种类型中，视杆层由反光绒毡层支持。两种类型的视杆结构和感受器细胞的细胞质内含物差异很大。前侧眼具有单一类型的视网膜，视杆由绒毡层支持。后侧眼和后中眼结构相似，在共同的屈光装置下方均有两种类型的视网膜。
