Purpose:
To illustrate the successful management of an occult intraocular foreign body (IOFB) lodged posterior to the iris causing persistent endophthalmitis.
Methods:
Two young male patients presented with corneal laceration, endophthalmitis and foreign body on X-ray but not localized by B-scan ultrasonography or gonioscopy.
Results:
Ultrasound Biomicroscopy (UBM) localized the foreign body lodged between the posterior iris and anterior lens surface accurately, which was successfully removed through the limbus using an external magnet.
Conclusions:
UBM is invaluable to accurately localize occult IOFBs lodged in the posterior iris or ciliary body region, which ensures good visual rehabilitation of these hitherto considered difficult cases.
