RESUMEN
PURPOSE: To quantify and characterize the epidemiology, treatments, long-term outcome, and use of resources for work tool-related eye injuries and their severity. METHODS: We included all new patients with a work tool-related eye injury treated at the Helsinki University Eye Hospital in 1 year. The data were from hospital records, examinations, and patient questionnaires. The follow-ups were at 3 months and 6 years. RESULTS: Work tools caused 3% (37/1151) of all eye injuries. The mean age was 37 and 84% were men. Most injuries (84%) occurred at work (17) or at home (15). There were 14 minor injuries, 12 contusions, 9 open globe injuries (OGI), and 2 eyelid wounds. The annual incidence of work tool-related eye injuries was 2.4/100,000 and hospitalization 0.6/100,000. At 6-year follow-up, we re-examined 18 patients and 17 were interviewed by phone. Four patients were blinded. We recorded 690 sick leave days and 43 major operations. No traumatic glaucoma was diagnosed. Fifteen patients needed lifelong follow-up. Permanent impairment occurred in 30% (11) of work tool-related eye injuries, from whom, nine were caused by manual tools. Work tools comprised 10% of the permanently impaired, but 2.5% of the non-permanently impaired cases among all eye injuries (1151). CONCLUSION: The proportional difference between the permanently impaired and the non-permanently impaired was higher in work tool-related eye injuries than other causes reported in previous Helsinki Ocular Trauma Studies. High-risk injuries were mainly caused by manual tools and nails and resulted in OGI.
