From: Role of B-scan ultrasonography in the localization of intraocular foreign bodies in the anterior segment: a report of three cases

Fig. 1

Preoperative photographs of the three patients. a Case 1, b case 2, c case 3. Slit-lamp photographs showing corneal laceration and lens opacity (a1-c1). CT scanning revealed intralenticular foreign bodies red arrow, a2-c2). UBM exam failed to detect any IOFB in the anterior segment (a3-c3). Axial scanning of B-scan ultrasonography shows the echo of the posterior surface of the lens (white arrow), with an abnormal echo in the posterior lens in case 1 (a4) but no evident IOFB in case 2 (b4) and case 3 (c4). Transverse scanning of B-scan ultrasonography clearly showed the position between the IOFB (red arrow) and the posterior lens capsule (white arrow)
