Document Summary
Notice that the left dotted line crosses over to the right. This would be nasal part of optic nerve. On the right hand side is what we actually see in our visual field. It is what we can actually see in the world and what is blind and our visual field. Pics are what actually see if we were to wiggle our fingers in front of them: we also have to look at one eye at a time. We cannot do two eyes at a time. Optic nerve is coming out from the retinas. Retina really is part of cns - part of the brain, that grows away from it. The two nerves cross at the optic chiasm. Once they pull away, it is the optic tract. Part of retina from the temporal portion as it continues back, it goes to the chiasma it stays on the same side of the brain - it does not cross.
