Retained intraocular foreign body.

The presence of an intraocular foreign body following eye trauma may not be readily apparent. Serous complications may include, inter alia, endophthalmitis, cataract, retinal detachment and siderosis bulbi. We report an iron intraocular injury due to hammering 'metal on metal', which was diagnosed using ultrasonic biomicroscopy and successfully removed. Two months post-operatively, unaided vision was 6/6.
