Cerebrospinal Fluid Diversion for Intracranial Hypertension with Visual Decline: A Case-Based Review

Abstract Idiopathic intracranial hypertension (IIH) is a potentially sight-threatening condition characterized by elevated intracranial pressure without an identifiable cause. This case highlights the importance of appropriate surgical selection in a patient with IIH and progressive visual deterioration. Given the patient's severely compromised optic nerves, ongoing visual loss, and intolerance to medical therapy, urgent intervention was required to decompress the intracranial venous system. The most effective options in such cases include venous sinus stenting or cerebrospinal fluid (CSF) diversion via shunting. In this patient, venous sinus stenting was not a viable option; therefore, CSF diversion through shunt placement was pursued.
