[Prognostic factors and visual outcome for open globe injuries with intraocular foreign bodies].

The aim of this study was to evaluate the clinical features as well as the visual results and determine the prognostic factors after the removal of retained intraocular foreign bodies (IOFBs).
At our centre we conducted a non-randomised, non-comparative retrospective analysis of records of 31 patients with intraocular foreign bodies treated using pars plana vitrectomy and other conventional surgical techniques during a 3-year period between January 2006 and December 2008. Using the OTS classification for ocular injuries (United States Eye Injury Registry [USEIR]), we evaluated the visual outcome and various pre-, intra- and postoperative clinical factors.
Almost all patients (96.8 %) were male with a mean age of 32.29 years ± 13.38 SD (SD = standard deviation). The most common cause of ocular injury was hammering (58 %), in 27 cases the IOFB was magnetic. Follow-up ranged from 1 to 34 months with a mean of 4.5 months. In 30 eyes, the IOFBs could be removed during the first surgery. The average time between injury and surgery was 15.78 ± 23.45 SD hours for 27 patients (87.1 %). In 3 cases the intraocular foreign body (IOFB) was removed 7, 9, 14 days after the injury. In one case the IOFB was removed in a second surgery 40 days after the injury. In 23 cases we performed pars plana vitrectomy, for 8 patients we performed anterior segment surgery, in 21 cases the lens was also removed. At the time of surgery initial vitreous haemorrhage was present in 17 patients (54.8 %). OTS score for ocular injury was calculated as 2.45 ± 0.78 SD. Initial visual acuity was below 20 / 200 in 61.3 % of the cases. Subsequent to surgical treatment over a mean follow-up of 2.5 months, 25 patients (80.64 %) achieved a visual acuity of 20 / 200 or better (0.69 ± 0.35 SD). Best corrected visual acuity was significantly better for ocular injuries with a higher OTS score (p = 0.000095). Other significant factors for good visual outcome were good initial visual acuity (p = 0.002), the absence of vitreal haemorrhagies (p = 0.024) and small size of the IOFB (p = 0.043). Postoperative complications included retinal detachment (9.67 %), endophthalmitis (3.22 %) and PVR (3.22 %).
Acceptable visual results could be achieved after the removal of posterior segment IOFBs by vitrectomy. A reliable classification of ocular injuries may provide significant information about the prognosis of injuries with intraocular foreign bodies.
