An Unusual Case of a Post-Traumatic Retained Periorbital Foreign Body in a Child.

Trauma to the periorbital region is common in children. Foreign bodies in traumatic cases may be missed where history, examination, and investigation are inadequate. Here, we report the case of a four-year-old boy who presented with a small forehead scar and left upper lid swelling two months post-trauma. Imaging showed a retained foreign body, and a pen tip was successfully removed surgically from the lid. The child recovered well post-operatively. Complications such as orbital cellulitis may arise if the foreign body remained undetected.
