BACKGROUND/ OBJECTIVES: The aim of the study was to evaluate the volume of intraocular foreign bodies (IOFB) using computed tomography (CT) volumetry as a prognostic factor for clinical outcome in open ocular injuries. PATIENTS AND METHODS: This study compared the volume of 11 IOFBs more than 5 mm(3) in size based on CT volumetry with the real size determined by in vitro measurement. A retrospective evaluation of clinical data, visual acuity, complications and relation of size of IOFBs with clinical outcome in 33 patients (mean age 41.0 ± 13.5 years) with open ocular injuries treated at our department between January 2005 and December 2010 was carried out. RESULTS: No significant differences were found between pairwise in vitro measurement and CT volumetric size (p = 0.07). All patients were surgically treated by pars plana vitrectomy. The mean follow-up time was 7.6± 6.2 months and the mean preoperative best corrected visual acuity (BCVA) was 0.063 ± 0.16 (logMAR 1.2 ± 0.79). Postoperatively, a mean BCVA of 0.25 ± 0.2 (logMAR 0.6 ± 0.69) could be achieved. Clinical outcomes were significantly better in injuries with small IOFBs measuring < 15 mm(3) (p = 0.0098). CONCLUSIONS: The use of CT volumetry is an accurate method for measurement of IOFBs. Exact data about the size and measurement of volume are also an important factor for the prognosis of clinical outcome in open ocular injuries with IOFBs and CT volumetry can also provide important information about the localization of IOFBs.
