Blindness from retrobulbar injection into the optic nerve.

S E Pautler, W S Grizzard, L N Thompson

    Ophthalmic Surgery
    |June 1, 1986
    PubMed
    Summary

    Sharp retrobulbar needles can cause severe visual loss by injecting into the optic nerve sheath. A modified technique is presented to reduce the risk of optic nerve trauma during retrobulbar injections.

    Area of Science:

    • Ophthalmology
    • Neuro-ophthalmology

    Background:

    • Retrobulbar injections are common ophthalmic procedures.
    • Atkinson's technique for retrobulbar injection has been associated with complications.

    Observation:

    • Two patients experienced severe visual loss after retrobulbar injections.
    • Clinical findings included optic disc edema, retinal edema, and hemorrhages.

    Findings:

    • Injection into the optic nerve sheath is a cause of visual impairment.
    • The use of sharp retrobulbar needles is implicated in optic nerve trauma.

    Implications:

    • A modified retrobulbar injection technique is proposed.
    • This modified technique aims to minimize the risk of optic nerve damage.
