Papilledema- A Ready Reckoner for Postgraduates
Introduction Papilledema is used to describe optic disc edema resulting from increased intracranial pressure while disc edema could be due to any cause. While disc edema can be unilateral or bilateral, papilledema is usually bilateral, however, it can be asymmetric, to begin with. Another important differential of true papilledema is pseudo papilledema which is seen in conditions like a small hyperopic optic disc or optic disc drusen, etc. This chapter shall entail a discussion on the etiopathogenesis of papilledema and the approach to diagnosis and management of papilledema. Papilledema and its mechanism It’s a form of bilateral optic disc swelling associated with increased intracranial pressure. An increase in intracranial pressure can occur secondary to an intracranial space-occupying lesion, cerebral venous thrombosis, or can be idiopathic as in the case of Idiopathic Intracranial hypertension (IIH). Figure 1 depicts the mechanism of the development of papilledema. Pseudo vs true p
