Idiopathic Intracranial Hypertension May Cause Vision Loss

Idiopathic intracranial hypertension (IIH), also known as pseudotumor cerebri, is an unexplained buildup of fluid in the brain that pushes on the optic nerve, often causing headaches, vision loss, or even blindness. Some people with the condition may report visual problems, nausea, and tinnitus.

Interestingly, the majority of patients who develop pseudotumor cerebri are obese, although the link is not well understood. Dr. Steve Roach, chief of neurology and vice chair of pediatrics at Nationwide Children's Hospital in Columbus, Ohio is part of a team of doctors who opened up the first center dedicated to treating children with pseudotumor cerebri.

IIH can be controlled by weight loss and medication. To slow the loss of vision, a procedure called optic nerve fenestration can be done; which leaves a small window in the sheath of the optic nerve to release pressure.
