Ocular and facial injuries associated with the use of immersion heaters in an inmate population.

Abstract

To report ocular and facial injuries caused by the use of electric immersion heaters in an inmate population. Prospective observational case series. Data were recorded over a six-month period on age, gender, mechanism of injury, examination, and treatment of Dallas County inmates who experienced ophthalmic injuries from immersion heaters and were referred to a tertiary-care center. Eight male inmates were treated for thermal ocular injuries, which occurred within jail cells as a result of cooking explosions from electric immersion heaters, known by inmates as "stingers." All patients had thermal eyelid burns, either first- or second-degree facial burns, and corneal abrasions with corneal edema. Corneal metallic foreign bodies were removed in one patient, and three patients underwent debridement for corneal sloughing. Immersion heater-related accidents may cause thermal injuries within the inmate population. Physicians evaluating incarcerated patients with ocular trauma should be aware of immersion heaters as a common cause.
