Patient: 22 years of age, male, BCVA light perception.
General Medical History: empty.
Ocular Medical History: injury of the eye during work.
Main complaint: sudden loss of vision and pain.
Methods: Colour photography, cranial Computer Tomography.
Findimgs:
(1) Colour photography: Colour image reveals a corneal opening, a flat anterior chamber, an iris injury, and a rupture of the crystalline lens.
(2) Cranial Computer Tomography: CCT showed an intraocular foreign body (arrow).
Discussion: Work-related injuries can cause significant morbidity in a young population of patients. Occupational injuries are common. In 2004 in the United States there were 1.3 million injuries that resulted in at least 1 day of missed work. Of these work-related injuries, 36 680 involved the eye. The lifetime prevalence of work-related eye injuries among US workers is 4.4% (1). Bauza et al. (2) analyzed the clinical characteristics of a total of 183 eyes with work-related open globe injuries. He found that the majority of injuries occurred in men (96.7%), and the most common cause was nail gun use (47.0%). Intraocular foreign bodies were found in 21%. Presenting visual acuity (VA) was worse than 20/200 in 66% and no light perception in 6%. Final visual acuity worse than 20/200 occurred in 37%. Significant prognostic factors for a final visual acuity of no light perception were rupture injury, and initial visual acuity of no light perception.
