目前已知的光感受器的分布只有一个完整的人类视网膜，只有猕猴视网膜的主要经络。可以在计算机重建的人和猴子的整个视网膜上绘制视锥细胞的图谱。青壮年人眼中心凹的最大视锥密度是视锥密度的2.9倍，这可能是个体视力差异的原因。视锥的分布在两种动物的中心凹呈放射状不对称，正如前面描述的视网膜神经节细胞的分布和视觉等敏感线的分布。鼻侧视锥细胞密度大于颞叶周边视网膜，这种鼻颞部不对称性在猴子中比在人类视网膜中更明显。
The distribution of photoreceptors is known for only one complete human retina and for the cardinal meridians only in the macaque monkey retina. Cones can be mapped in computer-reconstructed whole mounts of human and monkey retina. A 2.9-fold range in maximum cone density in the foveas of young adult human eyes may contribute to individual differences in acuity. Cone distribution is radially asymmetrical about the fovea in both species, as previously described for the distribution of retinal ganglion cells and for lines of visual isosensitivity. Cone density was greater in the nasal than in the temporal peripheral retina, and this nasotemporal asymmetry was more pronounced in monkey than in human retina.
