a pathway over which a visual sensation is transmitted from the retina to the brain. A pathway consists of an optic nerve, the fibers of an optic nerve traveling through the optic chiasm to the lateral geniculate body of the thalamus, and optic radiations terminating in an occipital lobe. Each optic nerve contains fibers from only one retina.
The visual information is processed through the neural circuits formed by retina cells in the opposite direction and then transmitted to the visual cortex of the brain through the axons of the ganglion cells. The blind spot is where the optic nerve (axons of the ganglion cells) leaves the retina to connect to the brain, which is located about 15 to 20 degrees away from the fovea along the horizontal temporal direction.
