Aim. To describe epidemiologic and clinical characteristics and prognostic factors influencing visual outcome after intraocular foreign bodies (IOFBs) injury. Methods. Medical records of 370 patients (373 eyes) with IOFBs were reviewed to identify the factors influencing visual acuity by univariate and multivariate analyses. Results. The majority of patients (97.0%) were men, with a mean age of 38.1 years. The most common cause of ocular injury was hammering (52.6%); magnetic IOFBs occurred in 84.7% of these cases. Factors associated with poor visual outcome (defined as <1.3 logMAR) included the following: age ≥50 years (P=0.046); worse presenting visual acuity (P<0.001); complications of retinal breaks (P=0.006) and endophthalmitis (P=0.032); vitrectomy (P=0.035); and intraocular C3F8 gas tamponade (P=0.038). Excellent visual outcome (defined as ≥0.5 logMAR) was associated with age <50 years (P=0.003); better presenting visual acuity (PVA) (P<0.001); wound length <4 mm (P=0.005); absence of vitreous hemorrhage (P=0.026) and retinal breaks (P<0.001); nonvitrectomy surgery (P=0.043); and use of balanced saline (P=0.029). Conclusions. Multiple prognostic factors were identified that may predict visual outcome and globe survival after IOFBs injury. Age, initial presenting visual acuity, wound length, complications (vitreous hemorrhage, retinal breaks, and endophthalmitis), surgical approach, and intraocular tamponade were significant predictors of visual outcome.

Study Results

AIM: To describe the clinical characteristics and analyze prognostic factors that influence visual outcome in 669 patients with intraocular foreign bodies (IOFBs). METHODS: Medical records of 669 patients with IOFBs from West China Hospital were reviewed. Best corrected visual acuity (BCVA) values were recorded using standard Snellen acuity chart and were converted to logarithm of the minimum angle of resolution (logMAR) scale for statistical analysis. The visual outcome was defined by the final BCVA (excellent visual outcome: final BCVA of 20/40 or better; poor visual outcome: final BCVA less than 20/200). Statistical analysis of collected data was performed using IBM SPSS Statistics version 23. A 2-tailed P value of less than 0.05 was considered statistically significant throughout the study. RESULTS: The average age ranged from 1 to 79 years old (mean age, 34.8±12.7 SD) and the majority of patients were men (626, 93.6%). The major cause of ocular injury was hammering (383, 57.2%). Almost all the patients (97.8%) underwent surgeries (97.8%) and the average time interval between injury and surgery was 26.4±322.3d (0-7300), while 327 patients received surgeries within 24h (48.9%) and 590 patients received surgeries within seven days (88.2%) after IOFBs injury. The poor BCVA was associated with older age (P=0.013), larger IOFBs size (P&#x003C;0.001), presence of complications (P&#x003C;0.001) and worse presenting BCVA (P&#x003C;0.001). On the contrary, younger age (P=0.005), smaller IOFBs size (P&#x003C;0.001), absence of complications (P&#x003C;0.001) and better presenting BCVA (P&#x003C;0.001) were considered to relate to excellent BCVA. CONCLUSION: Multiple prognostic factors may influence the final visual outcome, including age, size of IOFBs, complications and presenting BCVA. Meanwhile, further education and promotion on eye protection should be taken for the improvement on self-protection and self-health awareness.

Open Globe Injuries

This paper explored epidemiology and evaluation of posterior segment involvement as prognostic factors for functional outcome of patients with open globe injuries. A retrospective analysis of 151 patients with open globe injuries was conducted. Pre- and postoperative-corrected distance visual acuity (CDVA), epidemiologic data, classification of the injuries including the ocular trauma score (OTS), performed surgeries, intraocular pressure (IOP) and correlation analyses between OTS and postoperative CDVA were obtained. A total of 147 eyes were included in the study. Mean age was 42.9 ± 22.2 years, 78.2% were male, and 36.7% of injuries occurred in the workplace. Thirty-eight patients (25.9%) had intraocular foreign bodies. Concerning injury location, 51.7% of the injuries were located in zone I (cornea, corneoscleral limbus), 15.0% in zone II (up to 5 mm posterior the sclerocorneal limbus) and 32.0% in zone III (posterior of zone 2). Affected structures were eyelids (17.7%), cornea (74.8%), iris (63.9%), lens (56.5%), sclera (48.3%), retina (47.6%) and optic nerve (19.7%). Mean preoperative CDVA was 1.304 ± 0.794 logMAR and 1.289 ± 0.729 logMAR postoperatively (p = 0.780). Patients with posterior segment involvement had significantly worse postoperative CDVA than patients without (1.523 ± 0.654 logMAR vs. 0.944 ± 0.708 logMAR, p < 0.01). Predictive factors for good visual outcome of open globe injuries are good initial CDVA and ocular trauma affecting only zone I and II.

Purpose. To analyze risk factors for endophthalmitis and retinal detachment (RD) in patients with retained intraocular foreign bodies (IOFBs).Design. A retrospective, interventional, consecutive case series.Participants. All patients treated at Bascom Palmer Eye Institute for traumatic IOFBs between 1999 and 2008.Methods. Analysis of visual outcome, mechanism of injury, management, and postoperative course.Results. 108 eyes with IOFBs were identified. Endophthalmitis occurred in 7 eyes (6.4%) at presentation, and risk was higher with vegetable matter exposure (P=0.003). All eyes with posterior segment IOFBs received intravitreal antibiotics and there were no cases of endophthalmitis after initial management. RD was identified in 6 of 108 eyes (5.5%) at presentation. Risk factors were entry more than 5 mm behind the limbus (P<0.001) and posterior segment IOFB (P=0.028). Postoperative RD occurred in 11 of 102 eyes (10.7%). Risk factors for postoperative RD were preoperative endophthalmitis (P=0.001), posterior segment IOFB (P=0.008), and retinal impact sites (P=0.028).Conclusions. Risk factors for endophthalmitis included vegetable matter exposure and delay to initial management. Risk factors for RD were posterior entry site, posterior segment IOFB, endophthalmitis, and retinal impact sites. No eyes developed endophthalmitis after presentation.

Purpose To identify the prognostic factors that predict final visual outcome in eyes with posterior segment intraocular foreign body (IOFB) injuries managed by primary pars plana vitrectomy. Methods Ninety-six consecutive patients with posterior segment IOFB injuries were retrospectively reviewed. Factors analyzed included initial visual acuity (VA), time between injury and presentation, site of entrance wound, uveal prolapse, vitreous prolapse, traumatized iris, endophthalmitis, location and size of IOFB, use of scleral buckling and/or an encircling band, gas tamponade, lensectomy, number of surgical procedures, and development of retinal detachment. Data were analyzed using univariate and multivariate logistic regression analysis. Results After a mean follow-up of 8.6 months, 63 eyes (65.6%) achieved VA of 20/200 or better, and 9 eyes (9.4%) had total retinal detachment complicated by inoperable proliferative vitreoretinopathy. On univariate analysis, predictors of poor vision (hand movements or less) were poor initial VA, corneoscleral entrance wound, uveal prolapse, vitreous prolapse, traumatized iris, and development of retinal detachment. In contrast, predictors of good visual outcome (20/200 or better) were absence of uveal prolapse, no endophthalmitis, and no retinal detachment. Multivariate analysis identified corneoscleral entrance wound, uveal prolapse, and development of retinal detachment as the only factors significantly associated with poor visual outcome. Absence of uveal prolapse was the only factor significantly associated with good visual outcome. Conclusions Final visual outcome is greatly determined by the severity of the primary injury. On multivariate analysis, significant predictive factors of final VA were corneoscleral entrance wound, presence or absence of uveal prolapse, and development of retinal detachment.
