    A Taser dart electrode can perforate the eye, causing mechanical injury to the iris, lens, and retina. Despite initial surgical repair, delayed retinal detachment occurred, highlighting the potential for long-term ocular complications.

    Area of Science:

    • Ophthalmology
    • Trauma Surgery
    • Forensic Medicine

    Background:

    • Taser devices are used for less-lethal incapacitation.
    • Ocular globe perforation by Taser electrodes is a rare but serious injury.
    • The specific mechanisms and long-term consequences of ocular Taser injuries require further investigation.

    Observation:

    • A 21-year-old male sustained globe perforation from a Taser dart electrode.
    • The injury involved mechanical damage to the iris, lens, and retina, leading to retinal detachment.
    • Initial surgical repair of corneal and scleral wounds, traumatic cataract, and retinal tear resulted in partial visual recovery.

    Findings:

    • The patient experienced a delayed retinal detachment with proliferative vitreoretinopathy nine months post-injury.

  • The study suggests that the primary mechanism of ocular injury from Taser electrodes is mechanical, not electrical.
  • Visual recovery is possible, but long-term complications like proliferative vitreoretinopathy can occur.

    • Implications:

    • Taser use carries a risk of severe ocular trauma, including globe perforation and posterior segment damage.
    • Understanding the barbed design of Taser electrodes is crucial for safe removal and minimizing further injury.
    • Ophthalmologists and emergency personnel should be aware of the potential for delayed complications following Taser-related eye injuries.
