Papilledema is caused by too much CSF accumulate in the ventricles and optic nerve sheath. As the optic nerve sheath is continuous with the subarachnoid space of the brain (and is regarded as an extension of the central nervous system), increased intracranial pressure is transmitted through to the optic nerve. This will cause optic disc swelling.
but in normal pressure hydrocephalus there is no elevation of ICT , so you don't see pappiloedema
