Unilateral Optic Nerve Sheath Fenestration Effective in Pseudotumor

February 18, 2011

Ophthalmology: Optic nerve sheath fenestration is effective in pseudotumor (idiopathic intracranial hypertension).

This is because the intracranial fluid system is one closed system, and creating a leak in one area will reduce the pressure in the entire system.
