In a 2014 NIH-funded study of 165 patients with IIH and mild vision loss (the Idiopathic Intracranial Hypertension Treatment Trial), researchers found that acetazolamide treatment for six months in conjunction with a low-sodium weight-reduction diet modestly improved vision, reduced intracranial pressure, improved quality of life, and reduced papilledema.
