Mass and Shape as Factors in Intraocular Foreign Body Injuries
2006
Objectives To relate the nature, mass, and shape of intraocular foreign bodies (IOFBs) in a consecutive series of 69 patients to the mechanism, location, and visual outcome of the injuries and to compare these outcomes with data collected in our department over the last 70 years. Design Interventional case series of consecutive patients with IOFBs. Participants Sixty-nine patients with unilateral IOFBs. Intervention All patients underwent surgical removal of the IOFB. Main Outcome Measures Patient data included best-corrected visual acuity (BCVA), imaging and complication rates. For the IOFBs, material, mass, shape, and entry site were determined. Results The IOFB was metallic in 91% of cases. All but 2 patients were male (mean age, 37). Increasing IOFB mass was associated with posterior segment injury, retinal impact, presenting and final BCVAs≤20/200, the need for a primary globe repair before secondary IOFB removal, increasing complications, and the development of retinal detachment. Blade-shaped IOFBs penetrated to the posterior segment (97%) more frequently ( P Conclusions Intraocular foreign bodies of greater mass were associated with worse outcomes. We have observed an 82% reduction in number of IOFB injuries presenting over the last 70 years and outcomes have improved with advances in surgical technique. We advise that all patients with a visible or suspected IOFB be investigated with x-ray or CT and that they should all receive systemic antibiotics. We detected no advantage or disadvantage in delaying surgery until optimal surgical expertise and/or environment is available.
