Prognostic value of ocular trauma score for open globe injuries associated with metallic intraocular foreign bodies

Abstract

BackgroundThe prognostic value of the ocular trauma score (OTS) in patients who underwent 23-gauge pars plana vitrectomy (23-G PPV) for surgical removal of posterior segment metallic intaocular foreign bodies (IOFB) was evaluated.MethodsPatients who underwent 23-G PPV for surgical removal of retained metallic IOFBs were retrospectively analyzed. OTS score for each patient was calculated and raw scores were converted to their corresponding OTS categories. The final VAs in study patients were compared with their respective OTS categories.ResultsTwenty-five eyes from 25 patients were examined. Twenty-four (96%) of the patients were male, and the mean age was 34 ± 12 years. The time from injury to 23-G PPV was 9 ± 4 days. Fourteen (56%) patients had zone 1 trauma, eight (32%) patients had zone 2 trauma, and three (12%) patients had zone 3 trauma. Postoperative visual acuity was ≥ 20/200 in 14 (56%) of the patients and ≥ 20/40 in seven (28%) eyes. At the final visit, anatomical success was achieved in 86% of patients with retinal detachment at presentation. No statistically significant differences were found between our final VAs and OTS scores.ConclusionOTS, which provides prognostic information after general ocular trauma, may also provide valuable prognostic information for patients who undergo 23-G PPV for the surgical removal of metallic posterior segment IOFBs.

Comparison of Prognostic Prediction Value by Ocular Trauma Score with Visual Outcome in Ocular Foreign Body Trauma

“…It is reported that the injuries usually occur at workstations, meanwhile the case with 26,5% of the injuries presented in our series. IOFB has been found to be multiple in 25% of the cases in the literature [7] and 5,9% in our series.…”

“…Previous study reported that final visual acuities of 20/40 of more were obtained in 71% of IOFB-associated open globe injuries [6]. Another study reported that functional outcomes is not more common in eyes with IOFB [7]. Study from Kuhn et al reported that variable of IOFB was not included in OTS prognostic parameter [1].…”

“…IOFBs occurrence in this population has been consistent over time. Previous reports investigating the characteristics and prognostic factors of IOFBs were largely retrospective [1, 7–9]. Our study suffers from the same limitation.…”

“…Some studies have verified the reliability and predictability of this assessment system [12]. Several studies have reported that the OTS can be utilized to accurately predict outcomes [22,31,32]. However, Oiticica et al [33] found that the OTS had limited value in predicting long-term VA in children.…”
