The treatment depends largely on the underlying cause. However, the root cause of papilledema is the increased intracranial pressure (ICP). This is a dangerous sign, indicative of a brain tumor, CNS inflammation or idiopathic intracranial hypertension (IIH) that may become manifest in the near future.
Intracranial pressure (ICP) is the pressure exerted by fluids such as cerebrospinal fluid (CSF) inside the skull and on the brain tissue. ICP is measured in millimeters of mercury and at rest, is normally 7–15 mmHg for a supine adult. This equals to 9–20 cmH 2 O, which is a common scale used in lumbar punctures. [1]
Idiopathic intracranial hypertension (IIH), previously known as pseudotumor cerebri and benign intracranial hypertension, is a condition characterized by increased intracranial pressure (pressure around the brain) without a detectable cause. [2] The main symptoms are headache, vision problems, ringing in the ears, and shoulder pain.
The more common features of the disease are summarized in the acronym POEMS: Papilledema (swelling of the optic disc) often but not always due to increased intracranial pressure) is the most common ocular sign of POEMS syndrome, occurring in ≥29% of cases.
In children, symptoms of neuroborreliosis include headache, sleep disturbance, and symptoms associated with increased intracranial pressure, such as papilledema. Less common childhood symptoms can include meningitis, myelitis, ataxia, and chorea. Ocular Lyme disease has also been reported, as has neuroborreliosis affecting the spinal cord, but ...
Less common presentations include intracranial bleeding, aortic dissection, and pre-eclampsia or eclampsia. [6] Massive, rapid elevations in blood pressure can trigger any of these symptoms, and warrant further work-up by physicians. Physical exam would include measurement of blood pressure in both arms.
Increased intracranial pressure (ICP) is one of the major causes of secondary brain ischemia that accompanies a variety of pathological conditions, most notably traumatic brain injury (TBI), strokes, and intracranial hemorrhages. It can cause complications such as vision impairment due to intracranial pressure , permanent neurological problems ...
Cerebral edema is excess accumulation of fluid in the intracellular or extracellular spaces of the brain. [1] This typically causes impaired nerve function, increased pressure within the skull, and can eventually lead to direct compression of brain tissue and blood vessels. [1]
