    [Indications and technique for transconjunctival optic nerve sheath fenestration : Video article].
    Ophthalmologe 2017 Sep 13. Epub 2017 Sep 13.
    Klinik für Augenheilkunde, Medizinische Fakultät, Universität Freiburg, Killianstr. 5, 79106, Freiburg, Deutschland.
    Background: Placement of a ventricular shunt is the primary surgical procedure for lowering intracranial pressure in pseudotumor cerebri syndrome; however, if ophthalmological symptoms prevail over neurological symptoms or if there are no neurological symptoms at all, optic nerve sheath fenestration may be a valuable option for relief of pressure on the retrobulbar optic nerve when papilledema caused by pseudotumor cerebri syndrome threatens vision despite previous conservative measures.

    Methods: This review covers the indications, technique and results of optic nerve sheath fenestration compared to competing procedures based on a systematic literature search, analysis of own cases and a documentation of the surgical technique.

    Surgical Technique: After performing a medial transconjunctival orbitotomy the medial rectus muscle tendon is temporarily detached and the eye abducted by traction sutures. Read More
