Show Description +
Optic Nerve Sheath Fenestration (ONSF) has been shown to be effective in treating vision loss second to idiopathic intracranial hypertension, also known as pseudotumor cerebri. The ONSF procedure involves cutting a window into the optic nerve sheath, allowing the excess fluid to escape and harmlessly absorb into surrounding tissues. Amar Agarwal, MD, presents the surgical procedure starting with a 270 degree peritomy and blunt dissection under the tenons capsule After cutting the medial rectus and putting traction sutures on the remaining muscles, the globe is retracted to expose the optic nerve. A 4-mm incision is made in the sheath.

whew! this argawal fellow is fearless! nice work! one small point- just like the fenestration in the optic nerve reduces the pressure in the entire brain (which is why we do it in the first place!), as it's all one enclosed system, the optic nerve swelling in the fellow eye should always resolve- not just sometimes. unless, of course, these are adhesions somewhere preventing the reduction of pressure in the fellow eye.
