Work-Related Eye Injuries and Illnesses
W.F. PEATE, M.D., M.P.H., University of Arizona Colleges of Medicine and Public Health, Tucson, Arizona
More than 65,000 work-related eye injuries and illnesses, causing significant morbidity and disability, are reported in
the United States annually. A well-equipped eye tray includes fluorescein dye, materials for irrigation and foreign body
removal, a short-acting mydriatic agent, and topical anesthetics and antibiotics. The tray should be prepared in advance
in case of an eye injury. Eye patching does not improve cornea reepithelialization or discomfort from corneal abrasions.
Blunt trauma to the eye from a heavy object can cause a blow-out fracture. Sudden eye pain after working with a chisel,
hammer, grinding wheel, or saw suggests a penetrating globe injury. Chemical eye burns require immediate copious
irrigation. Nontraumatic causes of ocular illness are underreported; work-related allergic conjunctivitis increasingly
has been recognized among food handlers and agriculture workers who are exposed to common spices, fruits, and veg-
etables. The patient’s history of eye injury guides the diagnosis. Primary prevention and patient counseling on proper
eye protection is essential because over 90 percent of injuries can be avoided with the use of eye protection. As laser
use increases in industry and medical settings, adequate personal protection is needed to prevent cataracts. Outdoor
workers exposed to significant ultraviolet rays need sun protection and safety counseling to prevent age-related macular
degeneration. Contact lenses do not provide eye protection, and physicians should be familiar with guidelines for the
use of contacts in the workplace. (Am Fam Physician 2007;75:1017-22, 1024. Copyright 2007 American Academy of
