Which structure transmits visual information from the retina to the brain?

Signals from the retina are transmitted to the brain via the optic nerve, a bundle of retinal ganglion cell axons. After light is detected by photoreceptors and initial processing occurs in the retina, the resulting neural signals travel along these axons, exit the eye, some fibers cross at the optic chiasm, and then reach brain regions responsible for vision. The lens focuses light onto the retina, and the choroid provides blood supply; the retina itself is where light is detected and early processing happens, not the conduit to the brain.
