Other Diagnostic Studies
Lumbar puncture — If neuroimaging is normal, lumbar puncture should be done for opening pressure and analysis. Using correct technique, elevated pressure is defined as greater than 250 mmH20; measures between 200 and 250 mmH2O are considered equivocal. What constitutes normal pressure levels in children is still a matter of debate. Intracranial hypertension in the absence of other cause defines the entity of idiopathic intracranial hypertension or pseudotumor cerebri.
Fluorescein angiography — Fluorescein angiography may be helpful in the detection of early papilledema, showing dye leakage, disc vascularity, and excess early and late disc fluorescence. Ophthalmologists, however, find it incompletely reliable, especially in equivocal situations, and usually unnecessary in this clinical setting
