Recurrent corneal metallic foreign bodies in children with autism spectrum disorders.

Corneal metallic foreign body is a common condition in working-age adults due to occupational exposure, such as grinding, welding, and hammering. Ocular trauma is a leading cause of vision loss in children; however, corneal metallic foreign bodies are rare in the pediatric population. Here we describe 2 children suffering from autism spectrum disorders presenting with recurrent corneal metallic foreign bodies. Meticulous history revealed that both children extensively used a therapeutic home swing with metallic suspensions, suggesting the potential mechanism for the recurrent corneal metallic foreign bodies. Furthermore, the use of protective eyewear during swinging prevented further recurrences. Awareness of this potential danger is particularly important in children with disabilities, who may have difficulty communicating their concerns and cooperating during examination and treatment.
