This study was conducted to evaluate the roles of computerized tomography (CT) and echography in the management of open globe injuries, and to report the clinical presentation as well as surgical and visual outcomes at one institution.
This was a retrospective, interventional, consecutive case series. Outcome measures included imaging results, clinical course, and visual acuity outcomes.
Data was collected for 567 eyes in 565 patients who presented to Bascom Palmer Eye Institute between January 1, 1999 and December 31st, 2005. Mean visual acuity at time of diagnosis was 5/400, with vision <5/200 in 380 of 567 eyes (67%), and LP or NLP in 199 of 567 eyes (35%). CT was performed in 62% of eyes, and echography was performed in 42%. CT detected 94% of intraocular foreign bodies (IOFB), 28% of retinal detachments (RD), 74% of vitreous hemorrhages (VH), 48% of deformed globes, and located a rupture site or wound in 12%. Echography detected 88% of IOFB, 100% of RD, 100% of VH, 31% of deformed globes, and located a rupture site or wound in 15%.
CT and echography are both useful imaging modalities in the evaluation of open globe injuries. The data indicates that CT is superior for detection of IOFBs, whereas echography better identifies VH and RD.
