Abstract
This study aims to assess the accuracy of CT imaging in estimating intraocular foreign body (IOFB) size by comparing pre-operative radiological measurements with post-surgical dimensions. A retrospective review of 12 cases over 9 years at a UK tertiary centre. IOFB size on CT imaging was compared with post-surgical measurements. Soft tissue window CT overestimated IOFB size (p=0.025). Bone window CT was more accurate but still varied, with one-third differing by>50% to definitive size. We conclude that caution is needed in CT-based IOFB size estimation. Plain radiographs may provide additional accuracy.
