Development of a novel model of optic neuritis to assess neuroprotective and repair strategies in multiple sclerosis [PDF]

open access: yes, 2012
PhDMultiple sclerosis (MS) is a putative autoimmune disease of the central nervous system (CNS), which often affects the optic nerve pathway. Optic neuritis (ON) is a clinical feature of MS that can cause loss of vision due to conduction block and ...

Role of the optic nerve sheath diameter in the assessment of the effectiveness of decompressive surgery after malignant middle cerebral artery infarction

open access: yesArquivos de Neuro-Psiquiatria, 2022
Background After a case of stroke, intracranial pressure (ICP) must be measured and monitored, and the gold standard method for that is through an invasive technique using an intraventricular or intraparenchymal device.
