Vertebrado 
Pulpo 
1 representa la retina y 2 son las fibras nerviosas, incluido el nervio óptico (3).
En el caso de los vertebrados, 4 representa el punto ciego, que no está presente en el ojo del pulpo.

视网膜的后方称为眼底,在正对视神经起始处,有一呈白色的圆形隆起,称为视神经盘(又称视神经乳头)。此处是神经纤维进出的地方,没有感光细胞,不能感应到光线,故称为盲点。影像能够在盲点形成,但由于盲点没有感光细胞,所以不能产生神经脉冲,令脑部不能得到影像形成。

该现象最早由法国的埃德姆·马略特在17世纪60年代发现。

Optic disc 盲点 (眼)

Schematic diagram of the human eye, with the optical disc, or blind spot, at the bottom.
Optic disc showing microvasculature [epiCam].

The optic disc or optic nerve head is the point of exit for ganglion cell axons leaving the eye. Because there are no rods or cones overlying the optic disc, it corresponds to a small physiological blind spot in each eye.

The ganglion cell axons form the optic nerve after they leave the eye. The optic disc represents the beginning of the optic nerve and is the point where the axons of retinal ganglion cells come together. The optic disc is also the entry point for the major blood vessels that supply the retina. The optic disc in a normal human eye carries from 1-1.2 million neurons from the eye towards the brain.
