“…The mean age of the patients was 41.5 years (median: 46 years, range: 21 to 60 years). The fact that most of the patients were males and within the working age, the range is consistent with the literature [6], which suggests that young to middle-aged working males are more likely to suffer from ocular trauma. The present study also revealed that hammering metal was the most common cause of injury, which is similar to that of most other studies [12].…”

Purpose The aim of this study is to describe the epidemiological and visual outcomes and to identify the main prognostic factors of intralenticular foreign body (ILFB) injuries. Methods We performed a retrospective review of 21 patients (21 eyes) referred to Hebei Eye Hospital in North China from January 2012 to December 2017, who underwent surgical removal of ILFBs and associated ocular trauma repairs. Data regarding the patient demographics, cause of the injury, nature of the ILFB, clinical features, time interval between the injury and the ILFB removal, time interval between the presentation and the surgery, and the initial and final best-corrected visual acuities (BCVAs) were analyzed, and the main prognostic factors were identified. Results Male adults were most affected by ILFBs (90.5%). The mean age of the patients was 41.5 years (median: 46 years, range: 21 to 60 years). None of the patients were wearing goggles at the time of the injury. The most common ILFB cause was hammering the metal (57.1%), and most of the ILFBs were metallic (71.4%). After medical treatment, the final BCVA was improved significantly (Z = 2.49, P=0.015). There was a significant association between the ILFBs with posterior segment injuries and the final BCVA (χ2 = 10.03, P=0.01). Those factors showing no statistical association with the final BCVA included the age (χ2 = 0.36, P=1.0), gender (χ2 = 0.52, P=1.0), nature of the ILFB (χ2 = 1.11, P=0.54), entrance wound location (χ2 = 2.85, P=0.25), and time interval between the injury and the ILFB removal (χ2 = 1.87, P=0.23). Conclusion This is the first local study to explore the epidemiology of ILFB injuries and to identify the main prognostic factors. There was a significant association between the ILFBs with posterior segment injuries and the final BCVA. Improved public awareness and strengthened education regarding safety are the key approaches to reduce the incidence of eye injuries.

“…Only one-third of the patients in our study presented with an initial VA of 6/18 or better and 15% of patients had an initial VA of 6/9 or better. We found that better initial VA was associated with better final VA. is correlation has previously been found in numerous studies [10,12,13].…”

“…On the longterm, this also translates into poor visual outcomes through proliferative vitreoretinopathy (PVR) for which vitreous hemorrhage is the strongest stimulus [20]. We found a significant association with iris traumas, which was not identified in previous studies due to low incidence limiting statistical power [1,9,13,14]. Retinal detachment at presentation is also associated with poor visual outcome with development of PVR [8-10, 19, 21].…”

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.

“…18 Poor presenting visual acuity is regarded as the most important factor which determines the final visual outcome. 19,20 Other factors which influence final VA include the size of IOFB, age of patient and associated complications (retinal break, endophthalmitus, retinal detachment). 4 Decision regarding removal of difficult IOFB keeping in mind the risk of surgery can vary from case to case.…”

Purpose: To describe the epidemiological characteristics, management strategies and outcomes of intraocular foreign bodies (IOFB) presented in a tertiary care setup of Punjab. Study Design: Descriptive retrospective study. Place and Duration: Department of ophthalmology, Gujranwala medical college/teaching hospital, from January 2017 to December 2019. Methods: A retrospective review, of all the patients who had IOFB removal, was performed. Information regarding the nature and circumstances of injury, types of IOFB, operative procedure performed and patient’s pre-operative and post-operative Best Corrected Visual Acuity (BCVA) were analyzed. Descriptive statistics were used for analysis of data. Results: Record of 22 patients was retrieved. Out of which 18 (81.81%) were male and 4 (18.18%) were female. Mean age was 27.95 ± 9.325 years. Occupational trauma was the leading cause of injury (66.6%). Metallic objects were among the most common type of IOFB (66.6%) followed by glass, concrete stone (each 13.3%) and lead pencil (6.6%). Serious complications seen due to retained IOFB were phthisis bulbi (9.09%), retinal detachment (13.63%) and endophthalmitis (9.09%). On follow-up, 10 patients had BCVA less than hand movement (HM). 5 patients had BCVA of CF to 6/60, 3 patients had BCVA of 6/60-6/24 and 4 patients had better than 6/18. Conclusion: Most common cause of IOFB was occupational trauma and young age group of working class was the most common population affected. Treatment delay and complications contributed to poor prognosis. Ocular safety measures during high-risk work can reduce the risk of trauma. Key Words: Intra-ocular foreign Bodies, Retinal Detachment, Phthisis Bulbi.
