Contributions of Venous Dynamics and Implications for Therapy

Idiopathic intracranial hypertension (IIH) is one of the most common disorders seen in neuro-ophthalmic practice, yet its etiology remains elusive. In this session, factors contributing to the pathophysiology of IIH will be reviewed with special attention to the potential roles of metabolic factors, endocrine factors and cerebral venous dynamics. Upon completion of this session, participants should be able to: 1) describe metabolic factors that may play a role in the etiology of IIH; 2) describe endocrine factors that may play a role in the etiology of IIH; 3) discuss the role of cerebral venous dynamics in the pathophysiology of IIH and 4) discuss whether the findings of the IIHTT contribute to our understanding of the pathophysiology of IIH.
