Figure 2: B-scan ultrasound of the right eye shows an intraocular foreign body (IOFB) with shadowing behind the IOFB on the 7:30 equator posterior (730EP) and 7:30 longitudinal (L730) scans (a, b). There is moderate vitreous debris overlying the IOFB but no distinct track in the vitreous (white arrow).
