Eye Movements and the Intraorbital Subarachnoid Space: Potential Contribution of Altered Cerebrospinal Fluid Pumping in Optic Neuropathies.

Eye movements normally pump CSF around the optic nerve, but this pumping was subnormal in glaucoma and NA-AION, suggesting impaired CSF dynamics may contribute to these optic neuropathies.
