intraocular Foreign Bodies
A steel BB pellet underlies a retinal detachment in this ultrasonogram. The lair or replication echoes seen behind the BB are caused by reflections from the BB pellet itself.
Another clinical application of ultrasonography has been the localization of intraocular foreign bodies and the assessment of their metallic characteristics. The uses of ultrasonography in intraocular foreign body management include:
- localization
- axial length measurement in conjunction with x-rays for localization
- assessment of damage to the globe
- determination of magnetic properties
- extraction of nonmagnetic foreign bodies.
