Summary

Elastic cords can cause serious eye injuries, including retinal detachment and traumatic cataracts. Modifying elastic cord designs to prevent hook release could significantly improve safety and reduce ocular trauma.

Area of Science:

  • Ophthalmology
  • Trauma Surgery
  • Product Safety Engineering

Background:

  • Elastic cords are commonly used but pose risks of ocular injury.
  • Previous studies have not fully detailed the spectrum of injuries from elastic cords.

Purpose of the Study:

  • To determine the incidence and severity of eye injuries resulting from elastic cord use.
  • To analyze the types of ocular trauma and visual outcomes associated with elastic cord incidents.

Main Methods:

  • Retrospective review of emergency department patient records over 67 months.
  • Identified 28 patients with elastic cord-induced ocular trauma.
  • Collected data on demographics, injury mechanisms, ocular injuries, treatments, and visual acuity.

Main Results:

  • Common injuries included hyphaema/microhyphaema (71.4%) and commotio retinae (60.7%).
  • Severe injuries included corneal/scleral lacerations (7.1%), retinal tears (10.7%), retinal detachment (3.6%), lens subluxation (7.1%), and traumatic cataract (7.1%).
  • Mean visual acuity improved from 20/40 at presentation to 20/25 at follow-up.

Conclusions:

  • Elastic cords can lead to diverse and severe ocular injuries.
  • Design modifications to prevent spontaneous hook release are recommended to enhance user safety.
