[Comparison of conventional radiology, ultrasound and computer tomography in the preoperative localization of intraocular foreign bodies].

Three methods complementing each other are available for the preoperative intraocular localisation of foreign bodies. Basing on the results obtained, it is recommended, first of all, to localise the site of the foreign body by means of conventional x-ray film, followed by fine diagnosis via ultrasound and, finally, in problematic or doubtful cases, by means of computed tomography.
