Purpose: To evaluate the efficacy of routine radiologic evaluation of intracorneal metallic foreign bodies. Methods: Patients with confirmed intracorneal metallic foreign bodies by bimicroscopic exam were sent for radiologic evaluation before removal of the foreign body to rule out the presence of additional intraocular foreign bodies. Four radiologic views were taken: Waters view, Rhese view, Anterior/Posterior (A/P) view, and Lateral view. The radiographic studies were examined by both the referring ophthalmologist as well as the radiologist. Results: Seven out of seven eyes with confirmed intracorneal metallic foreign bodies by bimicroscopy were evaluated by four standard radiographic views and showed no radiographic evidence of metal in the orbital or ocular areas. Conclusions:The use of adjunct X–rays does not aid in the diagnosis of intracorneal foreign bodies in our study. This calls into question the usefulness of X–ray studies for the detection of small occult metallic foreign bodies in general. Routine radiologic evaluation by X–ray of patients with intracorneal metallic foreign bodies does not substiture for a comprehensive eye exam.
