The anteromedial eye of the web-building spider, Argiope amoena has been examined with light and electron microscopy. The eye consists of a cornea, a lens, a vitreous body and a retina. The retina contains 400 to 500 bipolar photoreceptor cells and pigment ce-ls which envelop the receptor cells. Microvilli extend laterally from the distal process of each receptor cell beneath the vitreous body. The microvilli interdigitate with those from neighboring processes to form rhabdoms. Multivesicular bodies occur in the rhabdomeric portion, and in an intermediate segment, between the rhabdomeric portion and the receptor cell body, are found mixed lamellar vesicular bodies and lamellar bodies. A single axon extends from the receptor cell. The site of origin of the axon from the cell varies depending on the location of the cell in the retina. The axon originates on the intermediate segment, or on the lateral surface or proximal end of the cell body. The axons join together in the postero-dorsal region of the eye and then extend to the first optic glomerulus as an ocellar nerve of about 3 mm in length. The pigment cells, whose cell bodies lie among those of the receptor cells or the axons, possess cytoplasmic prolongations which reach up to the vitreous body.
对结网蜘蛛悦目金蛛的前内侧眼进行了光学显微镜和电子显微镜检查。该眼由角膜、晶状体、玻璃体和视网膜组成。视网膜包含400至500个双极感光细胞以及包裹这些感光细胞的色素细胞。微绒毛从每个感光细胞位于玻璃体下方的远端突起横向延伸。微绒毛与相邻突起的微绒毛相互交错形成视杆。多泡体出现在视杆部分，并且在视杆部分与感光细胞体之间的中间段，发现有混合的板层泡状小体和板层小体。单个轴突从感光细胞延伸。轴突从细胞发出的部位因细胞在视网膜中的位置而异。轴突起源于中间段，或细胞体的侧面或近端。轴突在眼的后背部区域汇合，然后作为一条长约3毫米的单眼神经延伸至第一视神经小球。色素细胞的细胞体位于感光细胞或轴突的细胞体之间，其细胞质延伸直至玻璃体。
