Idiopathic Intracranial Hypertension | NANOS | Idiopathic intracranial hypertension (IIH), also called pseudotumor cerebri, is a condition in which there is high pressure in the fluid surrounding your brain, spinal cord, and optic nerves. This can cause headaches and problems with vision. | Idiopathic Intracranial Hypertension; Patient Brochure |

Eyelid Myokymia | NANOS | Eyelid myokymia is a very common condition that many people have experienced at least briefly at one time or another, though the exact prevalence is not known. Myokymia is characterized by involuntary fine contractions or "twitching" of the eyelids. | Eyelid Myokymia; Patient Brochure |
