BACKGROUND AND PURPOSE:IIH is a disorder associated with increased intracranial pressure with no clinical, laboratory, or radiologic evidence of an intracranial space-occupying lesion. The aim of this study was to establish ONSD standards of healthy pediatric subjects and compare the normal measurements with those of patients with IIH.

Guiding the optimal management of PNM will necessitate collaborative multicentre efforts and unique study designs.

The proposed method yielded good discrimination between LGG with and without 1p/19q codeletion. Results from this study demonstrate the great potential of this method to aid decision-making in the clinical management of patients with LGG.

The majority of our patients, who received chemotherapy for progressive OPG, experienced a decline in their visual function. New, more effective treatments are needed in order to preserve vision in this group.
