Brief Summary

The proposed study aims to evaluate optic nerve head blood flow and microcirculation in patients with idiopathic intracranial hypertension. For this purpose, optic nerve head blood flow will be examined in patients with IIH before and after therapy and additionally compared with healthy age- and sex-matched control subjects. In addition, other parameters will be measured, in particular retinal blood flow, retinal oxygen saturation and retinal neurovascular coupling.
