PurposePenetrating ocular trauma resulting from nails can have disastrous visual consequences. Ocular nail gun injuries occur when a nail propelled at high velocity penetrates the globe. The authors report four consecutive patients with ocular injuries resulting from nail guns.MethodsFour patients with ocular nail gun injuries are described: one with scleral penetrating injury, one with corneal penetrating injury, and two with perforating (through- and-through) injuries of the globe.ResultsThree of the four patients recovered good visual acuity after surgical intervention.ConclusionAlthough dependent on the site of impact, the visual prognosis may be less severe than expected because the nail penetrates the eye at a high velocity such that there are less contusive forces. Adherence to safety precautions involving the use of nail guns as well as the obligatory use of safety glasses should reduce the incidence of these injuries.
