To the Editor In their article regarding the Idiopathic Intracranial Hypertension (IIH) Treatment Trial (IIHTT), Wall and colleagues stated that “there are no properly designed and executed clinical trials to guide therapy.”1 They quoted Lueck and McIIwaine2 who correctly concluded a dearth of properly designed clinical trials in IIH at the time of their publication. In using this article, Wall et al1 did not consider a number of important published studies in the intervening 5 years since this Cochrane review2 was updated in 2008.
