    A child suffered optic atrophy after a truck tire stem injury introduced air into the orbit. This air likely disrupted the optic nerve's blood supply, causing vision loss.

    Area of Science:

    • Ophthalmology
    • Traumatic Injury
    • Pediatric Medicine

    Background:

    • Orbital trauma can lead to significant visual impairment.
    • Air embolism is a rare but serious complication of penetrating orbital injuries.

    Observation:

    • A six-year-old boy sustained a penetrating orbital injury from a truck tire inner tube stem.
    • The injury resulted in immediate, severe vision loss (no light perception) in the left eye.
    • Computed tomography revealed air bubbles around the optic nerve sheath, without direct optic nerve edema.

    Findings:

    • The likely cause of optic atrophy was vascular compromise of the optic nerve due to surrounding air.
    • The air's presence disrupted the optic nerve's blood supply, leading to irreversible damage.

    Implications:

    • Protective measures, such as covering tire air stems, are crucial to prevent similar pediatric eye injuries.
    • Prompt recognition and imaging are vital for diagnosing air embolism in orbital trauma.
    • Understanding the mechanism of injury can inform preventative strategies and clinical management.
