Guiding follow-up of paediatric idiopathic intracranial hypertension with optical coherence tomography.

Idiopathic intracranial hypertension (IIH) is uncommon in the paediatric population. Papilloedema is the hallmark sign and patients can suffer permanent vision loss as a consequence. We describe the role of optical coherence tomography (OCT) in the follow-up of two paediatric patients with newly diagnosed IIH.
