Study group discussion: Cool fact about optic nerve

I just came to know that the optic nerve is not a true nerve! It's just the extension of diencephalon..

That's the reason, in devic's disease (neuromyelitis optica) the optic nerves are involved since they are a part of central nervous system!

Wow o.O

That's why, Optic nerve is involved in multiple sclerosis too! It's the only myelinated nerve, part of the cns!

Yup. Also since it contains the same cover of meninges.. In cases of raised ICT, you see papilloedema.
