Abstract

Purpose of review

Idiopathic intracranial hypertension (IIH) can present with severe loss of vision or with ongoing vision loss despite maximal medical therapy; these situations require aggressive management with surgical interventions. To date, optimal surgical management has not been clearly defined. A review of the recent literature is undertaken to clarify the role of surgical interventions in IIH.

Recent findings

To date, no prospective, randomized study has been performed comparing lumboperitoneal shunt, ventriculoperitoneal shunt and optic nerve sheath fenestration/decompression. Procedure choice appears to be based on local availability and expertise, as well as the prominence of presenting symptoms. Delay in surgical intervention for fulminant and medically refractory cases leads to worse visual outcomes.

Summary

Surgical intervention for IIH will likely be based on local expertise until well designed, multicentered clinical trials clarify which intervention best suits a particular patient.
