Part of the Advances in Visual Science and Eye Diseases book series (AVSED, volume 1)


The optic nerve is a unique structure as it is only surrounded by cerebrospinal fluid in the nervous system (Fig. 8.1). The functions of cerebrospinal fluid (CSF) include nutrition supply, strength to intraocular pressure, taking away metabolic waste, etc. However, the functions and mechanism are not clear yet.
