    Optic nerve sheath fenestration (ONSF) is established for managing visual loss in chronic papilledema. This surgery involves careful optic nerve dissection, with recent studies suggesting broader pathophysiological effects than previously understood.

    Area of Science:

    • Ophthalmology
    • Neurosurgery

    Background:

    • Chronic papilledema can lead to significant visual loss.
    • Optic nerve sheath fenestration (ONSF) is a surgical procedure used in its management.
    • The efficacy of ONSF has faced skepticism, but it holds an established role.

    Purpose of the Study:

    • To review the established role of ONSF in managing visual loss from chronic papilledema.
    • To highlight the technical aspects of the surgical procedure.
    • To introduce recent findings on the potential pathophysiological effects of ONSF.

    Main Methods:

    • The abstract describes a surgical procedure involving microscopic dissection of the intraorbital optic nerve.
    • It references recent investigations into ONSF for ischemic optic nerve disease.

    Main Results:

    • ONSF has an established role in managing visual loss associated with chronic papilledema.
    • The procedure requires meticulous surgical technique to prevent nerve damage.
    • Recent research suggests ONSF may have more significant pathophysiological effects than previously recognized.

    Conclusions:

    • ONSF remains a key intervention for visual loss in chronic papilledema.
    • Precise surgical dissection is crucial for preserving optic nerve function.
    • Further research is needed to fully understand the pathophysiological implications of ONSF.
