Abstract

Papilledema refers to the swelling of the optic disk due to increased intracranial pressure. In clinical practice, papilledema is often confused with optic disc edema. Idiopathic intracranial hypertension (IIH) is a major cause of papilledema and there are still misconceptions about the etiology of IIH, the classification and examination of papilledema, and the treatment of IIH. This article elaborates on the misunderstandings that may exist in the diagnosis and treatment of papilledema, in order to lay a foundation for the standardized diagnosis and treatment of papilledema in China.
