Hyphema caused by a metallic intraocular foreign body during magnetic resonance imaging.
AI Summary
A patient with a metallic intraocular foreign body developed hyphema during MRI. This highlights MRI's danger with ferromagnetic IOFBs, emphasizing pre-MRI screening via history, X-ray, or CT.
Abstract
Purpose
To report a 63-year-old man with a retained intraocular foreign body who developed a hyphema during magnetic resonance imaging (MRI) of the brain.
Methods
Case report and review of the current literature on ocular injury caused by intraocular foreign bodies when subjected to an electromagnetic field.
Results
Our patient underwent a brain MRI, and the intraocular foreign body caused a hyphema and increased intraocular pressure. The presence and location of the intraocular foreign body were determined by computed tomography (CT).
Conclusion
Magnetic resonance imaging can cause serious ocular injury in patients with ferromagnetic intraocular foreign bodies. This case demonstrates the importance of obtaining an occupational history, and, when indicated, a skull x-ray or CT to rule out intraocular foreign body before an MRI study.
