Papilledema.

Abstract

Objective: This article describes the recognition, investigation, and management of papilledema.

Latest developments: Papilledema describes optic disc swelling (usually bilateral) arising from raised intracranial pressure. Due to the serious nature of papilledema, there is a fear of underdiagnosis and hence one of the major stumbling points is the correct identification of papilledema. While there has been a stepwise increase in the incidence and prevalence of idiopathic intracranial hypertension due to the worldwide epidemic of people living with obesity, secondary causes such as cerebral venous sinus thrombosis, intracranial masses, and infections must not be missed. Our ability to image the optic nerve has been greatly enhanced by the directed use of optical coherence tomography, with recent studies observing novel imaging findings that can help distinguish pseudopapilledema from papilledema. The structured investigation of papilledema is now routine and research into the management of CSF disorders is finding new avenues for targeted treatments.

Essential points: Confirmation of papilledema typically requires a thorough ocular examination including visual field testing. Ocular imaging such as color fundus photographs and optical coherence tomography are useful. Joint care between ophthalmologists and neurologists is key to treating the underlying condition and managing any visual dysfunction and headache.
