Introduction The goal of this study was to evaluate the utility of orbital ultrasonography and magnetic resonance imaging in the diagnosis of idiopathic intracranial hypertension (IIH). Method We reviewed the medical records of patients referred to our department for suspected IIH. Results Seven children were diagnosed with IIH. Nine children revealed pseudopapilledema by optic coherence tomography and/or orbital ultrasonography. When the axial sequences were reexamined, patients with papilledema had optic nerve sheath (ONS) enlargement (6.62 ± 0.70 mm); patients with pseudopapilledema had ONS diameter as 4.62 ± 0.64 mm. There was a significant correlation between the CSF opening pressure and ONS diameter ( p
