The Idiopathic Intracranial Hypertension (IIH) Treatment Trial enrolled participants in 2010-2012 and they were followed up for 6 months with the last follow-up in 2013. The study tested a glaucoma drug called acetazolamide (diamox) and weight loss plan to help improve vision for women who have idiopathic intracranial hypertension disorder. IIH is also called pseudotumor cerebri and usually affects overweight women. The most common symptoms associated with IIH are headaches and visual problems that include blind spots, poor side vision, double vision, and temporary episodes of blindness. The study results showed that a weight loss plan and acetazolamide can help preserve and restore vision for women with IIH.
