The Effect of Optic Nerve Sheath Fenestration on Intraocular Pressure in Patients With Idiopathic Intracranial Hypertension

Conclusions: Reducing the cerebral spinal fluid pressure (CSFP) at the level of the intraorbital optic nerve through an ONSF can slightly reduce the IOP. In those with evidence of posterior globe or scleral indentation/flattening, the reduction in IOP was higher, which supports the theory that CSF pressure indents the globe and leads to an increase in IOP. Although these changes in IOP are small, this study provides further evidence for a connection between IOP and CSFP.
