Predictive factors of visual outcome in posterior segment intraocular foreign body

Purpose. To identify predictive factors for visual outcomes of patients presenting with a posterior segment intraocular foreign body (IOFB). Methods. A retrospective chart review was performed for all consecutive patients operated for posterior segment IOFB removal between January 2009 and December 2018. Data were collected for patient demographics, clinical characteristics at presentation, IOFB characteristics, surgical procedures, and postoperative outcomes. A multiple logistic regression model was built for poor final visual acuity (VA) as an outcome (defined as final VA 50 letters or worse [Snellen equivalent: 20/100]). Results. Fifty-four patients were included in our study. Ninety-three percent of patients were men, with a mean age of 40.4 ± 12.6 years. Metallic IOFB comprised 88% of cases with a mean ± standard deviation (SD) size of 5.31 ± 4.62 mm. VA improved in 70% of patients after IOFB removal. Predictive factors for poor VA outcome included poor baseline VA, larger IOFB size, high number of additional diagnoses, an anterior chamber extraction, a second intervention, the use of C3F8 or silicone tamponade, and the presence of vitreous hemorrhage, hyphema, and iris damage. Predictive factors for a better visual outcome included first intention intraocular lens (IOL) implantation and the use of air tamponade. In the multiple logistic regression model, both baseline VA ( p = 0.009) and number of additional complications ( p = 0.01) were independent risk factors for a poor final VA. Conclusions. A high number of concomitant complications and poor baseline VA following posterior segment IOFB were significant predictive factors of poor visual outcome.

Anatomical Outcome

AIM: To evaluate the anatomical and visual outcome following removal of intraocular foreign body (IOFB) through pars planavitrectomy.MATERIAL & METHODS: A retrospective analysis of 11 cases of retained posterior segment foreign body that underwent pars planavitrectomy for removal of foreign body during the period of January 2013 to August 2017 was conducted. Demographics of patients, mechanism and details of injury, Snellen best corrected visual acuity, examination results at presentation and after surgery, any diagnostic imaging and surgical procedure were recorded and analysed.RESULTS: Out of eleven eyes of eleven patients (mean age= 25.4}8.6, range 22 50 years; all male) preoperative retinal detachment and endophthalmitis was seen in 27.3% and 36.4% of cases respectively. Eighty-two percent of cases presented within 17 days of sustaining injury. Foreign body size ranged from 2mm to 8 mm and all were magnetic metal. After vitrectomy and removal of foreign body, the number of eyes with vision of hand motion or worse decreased from 72.7% to 27.3%. Similarly 45.5% of eyes gained best corrected postoperative visual acuity of better than 6/60. Anatomical success could be achieved in 81.8% of eyes.CONCLUSION: Anatomical outcome following vitrectomy in eyes with retained posterior segment IOFB in terms of retinal attachment is sufficient; however, visual outcome can be affected by other collateral ocular injuries and their sequelae.Journal of Universal College of Medical Sciences, Vol. 5, No. 2, 2017, Page: 45-48

The Mean

Introduction: Posterior segment retained Intraocular foreign body (IOFB) management is challenging. Facility of pars plana vitrectomy (PPV) and availability of well trained vitreo retina surgeons are the basic need to accomplish this work. Encircling band provide permanent 360° support to close the anterior retinal break and prevent traction on the retina. The objective of this study is to analyse the clinical characteristics and predictors of the final visual outcome and survival of the globe in cases of retained IOFB in the posterior eye segment. Materials and methods: A hospital based retrospective observational study was conducted. All the patients of retained IOFB in the posterior segment presented from January 2016 to June 2019 were enrolled. Patients presented with visual acuity of NPL were excluded. Statistical analysis was performed using a variety of tests using SPSS version 21. Results: Forty eyes of 40 patients were included. The mean age was 27.08±10.68 years (range 5-66). 95% of our patients were male. Most of them (52.5%) worked on the farm. 26(65%) of 40 eyes had Zone I injury. The median time spent before presentation was 13.5 day. Retinal detachment, vitreous hemorrhage, and endophthalmitis were present in 15, 23 and 5 eyes, respectively, before IOFB removal. The mean LogMAR visual acuity was improved significantly from 2.50±0.87 to 1.33± 1.01 (p=0.003). Poor presenting visual acuity, retinal detachment and large diameter of IOFB were found as the predictor of poor final visual acuity. Conclusion: Pars plana vitrectomy by a vitreo retinal surgeon can give encouraging results in the cases of retained posterior segment IOFB. Poor presenting visual acuity, large diameter of IOFB and RD before IOFB removal are predictors of poor visual outcome.

Purpose: To investigate characteristics of Open Globe Injuries (OGI) that presented with Intra-Ocular Foreign Body (IOFB), along with their long-term visual outcomes and complications. Methods: Retrospective interventional consecutive case series of OGIs with IOFBs that presented at Massachusetts Eye and Ear from 2010 to 2015. Data collected included time from injury to OGI repair, location of IOFB, retinal detachment (RD) rate, presenting and final visual acuity and subsequent surgeries. Results: Fifty-seven consecutive cases of OGIs with IOFBs were included. Mean follow-up was 28 months and median time from injury to OGI repair was 0 days. Overall, 38/57 (66.7%) eyes achieved final vision of 20/40 or better and 43/57 (75.4%) 20/150 or better. Thirty-three cases had IOFBs in the anterior segment only, 24 cases had posterior segment involvement. Thirty percent of cases (17/57) were complicated by an RD, 58.3% (14/24) in the posterior versus 9.1% (3/33) in the anterior IOFB group ( P = .01). There were no cases of endophthalmitis. Posterior IOFB and higher zone of injury were risk factors for RD both at presentation (both P < .001) and post-primary repair (both P < .001). Posterior IOFB was associated with higher vitrectomy rates both at presentation ( P < .001) and post-primary repair ( P = .002) and worse long-term visual outcome ( P = .01). Conclusions: OGIs with IOFB involving the posterior segment are associated with higher complication and re-operation rates and worse visual prognosis compared to those involving the anterior segment only.

The Mean

Purpose: To evaluate clinical characteristics, visual outcomes and globe survival after intraocular foreign body removal from posterior segment via pars plana approach. Methods: A hospital based retrospective study. All the patients of penetrating eye injury with intraocular foreign body in posterior segment as detected by computed tomography were enrolled from 2012 to 2014.Results: Thirty patients of 30 eyes were included. The mean age was 27.7 years. (2-52). Twenty-four (80%) were male. Out of 30 eyes 19 (63.3%) eyes had injury at Zone 1 and 11 (36.7%) eyes had injury at Zone 2. The mean time spent between primary repair following surgery and intra ocular foreign body removal, was 15.47 days. Retinal detachment and endophthalmitis prior to intraocular foreign body removal was present in 9/30 of eyes. We looked for correlation between post operative Phthisis bulbi with zone of injury and pre operative endophthalmitis and preoperative retinal detachment. However, p value for the above correlation was more than 0.552 and 0.815 respectively, which was statistically not significant.Conclusions: The eyes with posterior segment intraocular foreign bodies showing clinical features of preoperative endophthalmitis, retinal detachment and the zone of injury also did not have any direct significance with globe survival.

Current Case

Intraocular foreign bodies (IOFBs) are an important cause of visual loss. The current case describesa case of retained intraocular foreign body with secondary retinal detachment in a phakic eye in a38-year-old man. The foreign body was safely removed through the sclerotomy port withouttouching the crystalline lens. The current case report wanted to show the anatomic and visualoutcomes of vitreoretinal surgery in such cases.
