Elastic cords with hooks can cause severe eye injuries, including penetrating trauma and vision loss. A design modification may help prevent such accidents.

Area of Science:

  • Ophthalmology
  • Trauma Surgery
  • Biomedical Engineering

Background:

  • Elastic cords with hooks are common household and recreational items.
  • Accidental ocular trauma from these devices can lead to severe visual impairment.

Purpose of the Study:

  • To evaluate the spectrum of ocular injuries caused by elastic cords with hooks.
  • To highlight the potential severity of these injuries.
  • To suggest a design modification to prevent future trauma.

Main Methods:

  • Retrospective case series of five patients treated for ocular trauma.
  • Evaluation of injury types, severity, and final visual acuity.
  • Review of device design and potential for modification.

Main Results:

  • Five patients experienced ocular trauma over 13 months.
  • Injuries included hyphema, angle recession, lens subluxation, choroidal rupture, vitreous hemorrhage, retinal detachment, and scleral rupture.
  • Two patients had penetrating injuries; three had visual acuity of 20/200 or less.

Conclusions:

  • Elastic cords with hooks pose a significant risk of severe ocular injury.
  • Penetrating trauma and permanent vision loss are possible outcomes.
  • A simple design modification could potentially reduce the incidence of such injuries.
