Case in brief
A 31-year-old man presented with left-eye pain and severe vision loss seven days after penetrating injury from a metallic object. Examination revealed a corneal laceration with iris incarceration, anterior chamber inflammation, and traumatic cataract; the retina could not be visualized. Imaging and findings at vitrectomy identified endophthalmitis, rhegmatogenous retinal detachment, and a 35-mm curved intraocular foreign body, which was successfully removed. The foreign body had not been detected on initial B-scan ultrasonography.
What made this case unusual
The retained metallic foreign body was 35 mm long and accompanied by traumatic cataract, endophthalmitis, and rhegmatogenous retinal detachment.
Diagnostic / clinical pearl
A negative initial B-scan did not exclude a large intraocular foreign body in this case; computed tomography contributed to its detection.
