IIIH stands for Idiopathic Intracranial Hypertension is a very rare condition (1-2 in every 100,000). This means that there is too much cerebrospinal pressure in the skull.

At present there is no cure for this condition so its about managing the symptoms. There are a few medications that are used to help reduce the pressure, these are called Diuretics, most commonly used are the following, Acetazolamide (Diamox), Topiramate and Furosemide. It may also be recommended that you have regular Lumbar Punctures to reduce the pressure. This would be taken alongside pain relief and anti sickness medications.
If these methods do not control the pressures enough it may be recommended that you undergo surgery to insert a shunt. There are presently 3 types of shunts that are commonly used these are: - Lumbar Peritoneal (LP) shunt - Ventriculoperitoneal (VP) shunt - Ventriculoplural (VPL) shunt
There is other shunt options that are less commonly used, your medical team will decide the best option for you. There is also one more surgery option that is not commonly used nowadays called Optic Nerve Fenestration. This will not be considered unless you are in danger of loosing your sight.
