Endoscopic transconjunctival optic nerve sheath fenestration for progressive idiopathic visual field deficit: a case report.

ABSTRACT: Intra-orbital optic nerve sheath fenestration (ONSF) is an effective option in patients with progressive vision loss due to idiopathic intracranial hypertension. Most proposed techniques involve surgical trauma and require disinsertion of the medial rectus muscle; thus, less invasive surgical procedures are needed. Here, a feasible and effective technique of endoscopic intra-orbital ONSF through a conjunctival incision is presented, in a patient with a progressively compromised visual field, papilloedema, and distended subarachnoid space around the optic nerves. The retrobulbar segment of the optic nerve was exposed for incision, avoiding manipulation of the lateral orbital rim bones and irritation of the ciliary microvessels and nerves. The patient regained the entire visual field. ONSF w
