To diagnose Intracranial Hypertension, a person will need to under go a Lumbar Puncture to get a reading of the CSF levels in the brain. Before the lumbar puncture is done, a person will either have an MRI or CT scan or both to rule out other brain conditions. Intracranial hypertension can sometimes be found through MRI's and CT scans but to definitely diagnose, a Lumbar puncture is needed.
In my personal experience, i have been told by my Neurologist that an opening pressure of 25 or higher indicates that intracranial hypertension is present. An opening pressure of 20-25 is a grey area and depending on the person, it can mean that intracranial hypertension is present or it can be seen as normal. Anything lower than this is considered normal.
Seeing a Neurologist is essential when being diagnosed with Intracranial Hypertension and if you have been experiencing vision loss, an opthamologist is also essential.
