Abstract
Purpose: :
To evaluate the diagnostic accuracy of clinical eye examination and radiographic imaging in theidentification of intraocular foreign bodies (IOFBs) in open globe traumatic injuries.
Methods: :
A retrospective chart review of open globe traumatic injuries with IOFBs presenting to University Hospital at New Jersey Medical School (NJMS) between 1998 and 2008.
Results: :
527 patients presenting with open-globe traumatic injuries to the University Hospital, NJMS between 1998 and 2008 were identified. Of these, 74 patients had surgically confirmed IOFBs. There were 71 males and 3 females. The mean age at presentation with traumatic injury with an IOFB was 33 years (range, 8 to 69 years), and mean follow up duration was 17.6 months (range, 1 day to 90 months). Foreign bodies were identified as glass (13), metal (58), wood (1), plastic (0), and other (2). There were 24 anterior segment (AS) IOFBs, 45 posterior segment (PS) IOFBs, and 5 were contained within both segments. Initial clinical eye exam identified an IOFB only in 45.6% (34/74) of patients. B-Scan of the eye revealed IOFB in 51.9% (14/27) of cases. CT-Scan of the orbits identified IOFB in 94.9% (56/59) of cases. Clinical eye examination was performed in 100% of patients. B-scan was performed when posterior segment pathology was suspected. CT scan was performed when IOFB or orbital fractures were suspected.
Conclusions: :
CT scan was the most reliable method for identifying IOFBs in patients presenting with open globe traumatic eyes in comparison to clinical eye examination and B-scan ultrasound. Results were consistent regardless of IOFB location within the globe.
