Sometimes. Many times patients develop transient obscurations of vision, or brief episodes of blurry vision. These are temporary if treatment ensues promptly. Long term high intracranial pressure can produce permanent defects in vision due to damage of the optic nerve. This condition needs to be closely monitored by both neurologists and ophthalmologists.
Absolutely. Optic nerve damage leading to visual impairment or blindness can be caused by intracranial hypertension. This is why it is essential that an ophthalmologist is involved with the management of this disorder.
Unknown cause. Ideopathic means unknown. Pressure in the brain is usually due to tumor or infection. If these are ruled out, the pressure is considered ideopathic. Another term can be pseudo tumor. There can be normal pressure hydrocephalus in the elderly, but reducing "pressure" makes them better.
Pseudotumor cerebri. This is a serious disorder and there are a number of treatments available including medication to reduce the pressure. There is also a surgical procedure that requires placing a tube in the spine canal and diverting excess spinal fluid into the abdomen. If you are seeing a neurologist for this the various options can be explained more fully.

Spinal tap. The most direct test is to measure pressure in the spinal fluid. This is done with a spinal tap and pressure measuring column. The fluid column is measured, and then the fluid is drained off. Just draining the fluid can relieve symptoms. Analysis of the fluid would rule out more serious conditions. This procedure is easily performed in a doctor's office or emergency room.
CT, MRI, LP. Imaging studies like cts or mris are useful to start with to make certain that there isn't actually a lesion (ie. Tumor) that is causing the intracranial pressure. Also the cerebral ventricles can be visualized to ensure there isn't frank hydrocephalus. A physical examination with fundoscopy can reveal transmitted pressure to the optic discs. Finally, an LP can measure the spinal pressure.
PseudoTumor Cerebri. Also called Benign Intracranial Hypertension or Psedotumo Cerebri It is a neurological disorder in ehich there is increased Intracranial Pressure when there is no tumor other disease Symptoms are Headache Nausea and Vomiting and pulsating sounds in the ears, double vision. It can lead to swelling of theoptic nerve if not treated&loss of vision Diagnosed by Brain Scan&LP Treated with rpt LPs& Diamox (acetazolamide)
Spinal tap. The neurologic exam and the history obtained by the neurologist are the starting point. Examination of the eyes and the fundi of the eye can give information about whether or not there is pressure transmitted to the optic apparatus. Ct scans or mris rule out any mass lesion or obstructive hydrocephalus. A spinal tap is done to document the CSF pressure and if there is any relief with removal of csf.
