Purpose Of Review: We aim to provide a comprehensive and updated review on idiopathic intracranial hypertension (IIH), including the most current studies and treatment options. Special focus will be put on recent theories about the pathophysiology, and on newer prospective studies on treatment modalities.
Recent Findings: The Idiopathic Intracranial Hypertension Treatment Trial (IIHTT) provided evidence supporting acetazolamide as a well tolerated first-line therapy in IIH patients with mild vision loss.
