Localization of suspected intraocular foreign bodies with a modified Delta 2020 scanner.
Metallic foreign bodies were localized in seven patients using a modified Delta 2020 scanner. In six of these seven, we compared the localization obtained by sector CT scan with ultrasound. The two methods were found to be complementary, with the sector CT scan giving more positive and more easily interpreted localizations, and ultrasonography giving more detailed soft tissue diagnosis. The new sector CT scanner greatly raised the level of confidence in the localization of metallic foreign bodies; however, we recommend the combined use of both techniques for a complete evaluation.
