title: Unusual cause for non-detection of retained metallic foreign body on ocular ultrasonography.
abstract: Ultrasound biomicroscopy has become a valuable adjunct in the evaluation of occult ocular foreign bodies. An unusual cause for non-detection of a metallic retained intraocular foreign body is described. In this case, the usual 'shadowing' was not discernible as the foreign body was lying just over the optic disc.
