Complications of Optic Nerve Sheath Fenestration as a Treatment for Idiopathic Intracranial Hypertension

ABSTRACT

There are a number of surgical options for treatment of idiopathic intracranial hypertension (IIH) when it is refractory to medical treatment and weight loss. Optic nerve sheath fenestration (ONSF) is one of these options. Use of this procedure varies among centers due to experience with the procedure and concern for associated complications that can result in severe loss of vision. This review summarizes the literature concerning post-surgical complications of ONSF for IIH.
