a A box and whisker plot of the optic nerve sheath diameter (ONSD) in controls and patients at risk of IIH who had arterial inflow both above and below 1410 ml/min. Hyperemia correlates with optic nerve sheath dilatation and therefore elevated intracranial pressure. b A box and whisker plot of the optic nerve sheath diameter (ONSD) in controls and patients at risk of IIH who had sagittal sinus percentage (%SSS) returns both above and below 41%. Reduced venous return correlates with optic nerve sheath dilatation and therefore elevated intracranial pressure
