Idiopathic Intracranial Hypertension: Changing Trends

Idiopathic intracranial hypertension (IIH) is a disorder of raised ICP without any obvious underlying brain pathology. Early intervention remains the key to success. The patients with BIH and vision threatening papilloedema should be taken up for optic nerve fenestration and the results are favorable in terms of visual outcome. The procedure is safe with few intraoperative or postoperative complications.
