Papilledema is a rare optic nerve disorder. IIH mimics a brain tumor, so you will exhibit signs of papilledema. This is called idiopathic intracranial hypertension (IIH) or pseudotumor cerebri. Sometimes, the cause of increased brain pressure is unknown. It is a slow-growing tumor that increases ICP in 27% of cases. Unilateral papilledema is caused by an optic nerve glioma. These include tetracycline, lithium, minocycline, nalidixic acid, corticosteroids, and some anti-hypertensive drugs such as nitroprusside, nitroglycerine, hydralazine, and nicardipine. Infections that cause swelling of the brain and brain tissues may also lead to bilateral papilledema.Ĭertain medications can elevate your ICP as a side effect.
In general, any brain lesion that occupies space or causes cerebrospinal fluid (CSF) to accumulate can raise your brain pressure. Papilledema can be caused by a variety of diseases, injuries, and conditions that increase intracranial pressure (ICP). Optic disc edema affects your central visual field at the onset, reducing your ability to distinguish objects and shapes. It does not change your central vision and visual acuity until later. Papilledema commonly affects your peripheral vision. Optic disc edema: Also known as pseudopapilledema, it is caused by optic nerve damage.True papilledema: Results from increased brain pressure due to an underlying condition.While both lead to optic disc swelling, they have different causes: Papilledema is not the same as optic disc edema. 1 Is optic disc edema the same as papilledema? Unless treated, elevated brain pressure can lead to permanent nerve damage, vision loss, and death. Papilledema or optic nerve swelling indicates the presence of a serious and often life-threatening condition. In rare cases, it has a unilateral presentation and affects one eye. It is usually bilateral and affects both eyes. Papilledema can develop within hours or weeks, depending on the underlying cause. It is caused by intracranial hypertension (IH) or increased pressure within and around the brain. Papilledema or papilloedema is the swelling of the optic disc or the part of the optic nerve located inside the eye. The optic nerve (also called the second cranial nerve or CNII) transmits visual information from the eyes to the brain.
