Ocular Foreign Body, CT scan

Foreign bodies are one of the most common causes for ophthalmologic emergencies, which represent 3% of all United States emergency room visits. Risk factors include being male, not wearing eye protection, and performing a metal-on-metal task (hammering or chiseling a metal object). The mean age at which injury occurred was 33 years. The foreign body most frequently enters the cornea, and approximately 65% of them land in the posterior segment  (adapted from Webeye.ophth.uiowa.edu)
