Figures
- Fig 1.
Example of our measurement method. ONSD is measured 10 mm anterior to the optic foramen. In this example, a distended nerve is measured.
- Fig 2.
Mean ONSD of each age group in our control cohort, stratified by sex. Error bars at the top of each column represent the standard error for that column, ranging from 0.07 to 0.16 mm.
- Fig 3.
Mean ONSD width by age group in controls versus patients with IIH.
- Fig 4.
Scattergraph and trend lines of the mean ONSD of both controls and patients with IIH.
Tables
Criteria 1) If symptoms or signs are present, they may only reflect those of generalized intracranial hypertension or papilledema 2) Documented elevated intracranial pressure measured in the lateral decubitus position 3) Normal CSF composition 4) No evidence of hydrocephalus, mass, structural, or vascular lesion on MRI or contrast-enhanced CT for typical patients, and MRI and MR venography for all others 5) No other cause of intracranial hypertension identified -
↵a All of the above criteria should be met in order to make the diagnosis of IIH.
