Purpose:
To describe the ophthalmoscopic and radiologic findings of a patient who sustained blunt orbital trauma. A piece of bone from the fractured orbital wall caused an intraocular foreign body.
Design:
Case report.
Methods:
An 18-year-old man underwent full ophthalmoscopic examination 1 week after sustaining blunt ocular trauma to the right eye while playing basketball. B-scan ultrasonography and computed tomography of the orbits were also performed.
Results:
Visual acuity, intraocular pressure, and anterior segment examination were normal. Funduscopic examination revealed a fragment of bone that had penetrated the sclera, choroid, and retina. A hole in the sclera was visible. No treatment was performed. Three months later, the patient had no ocular complaints or complications as a result of this injury.
Conclusion:
Bone from a patient's orbit may cause an intraocular foreign body that may be followed conservatively in certain circumstances.

Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...

The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
