Avoid delaying vitrectomy by foregoing diagnostic testing if the intraocular foreign body is visible and endophthalmitis is incipient

In opaque-media eyes with a suspected IOFB treatment delay is common, due to waiting for computed tomography (CT) - instead of ultrasonography, which can safely identify the IOFB in over 90% of cases. Expediting surgery is the best prophylaxis against post-presentation endophthalmitis. Our case highlights the benefits of early vitrectomy based on direct inspection of the IOFB alone; instant ultrasonography instead of a CT-caused delay may save eyes with infection developing behind media opacity.
