Duplicity of the white-tailed deer (Odocoileus virginianus) retina, ie, cone and rod function, was established by histologic and electrophysiologic data. The presence of cones and rods in the deer retina was shown by light and electron microscopy. Electroretinography revealed distinct photopic (bp) and scotopic (bs) components in the b-wave of the electroretinogram that are characteristic of the cone and rod activity. These findings are in contrasts to the popular belief that deer have retina composed entirely of rods.
白尾鹿（弗吉尼亚鹿）视网膜的双重性，即视锥和视杆功能，已通过组织学和电生理学数据得到证实。光镜和电镜观察显示了鹿视网膜中视锥和视杆的存在。视网膜电图显示，视网膜电图的b波中存在明显的明视（bp）和暗视（bs）成分，这是视锥和视杆活动的特征。这些发现与普遍认为鹿的视网膜完全由视杆组成的观点形成对比。
