What Is Papilledema?
2. Causes of Papilledema
The swelling of the optic disc, also called papilledema is a result of high intracranial pressure. This means that the underlying conditions that lead to increased pressure are the true causes of papilledema.
When the pressure around or within the brain increases significantly, it presses against other tissues including the optic nerve. This compression causes the optic disc, which is the end part of the optic nerve within the back of the eye, to swell.
