Pseudotumor Cerebri Support Group
Pseudotumor cerebri (PTC) is a neurological disorder that is characterized by increased intracranial pressure, in the absence of a tumor or other diseases affecting the brain or its lining. Diagnosis requires brain scans and lumbar puncture. Characteristic symptoms are headache, transient visual obscurations or transient visual loss in one or both eyes usually lasting...
Vision loss is not always necessarily permanent, so I believe that statistic is referring to the wide range of visual disturbances that occur with IIH. It goes on to say that without treatment "about 10 percent of patients with IIH suffer severe vision deficits and 5 percent lose all sight in one or both eyes". Which is kind of reassuring because both of those are relatively low percentages and that's without treatment, if you are treating the IIH I can imagine that total vision loss is highly unlikely.
You will be missed, I hope you have a great weekend. :)
