Background and Objective: This study aimed to identify the prognostic factors regarding the visual and anatomic outcomes of eyes with posterior segment intraocular foreign body (PS-IOFB)., Patients and Methods: The medical records of 95 patients who underwent pars plana vitrectomy and PS-IOFB removal between 2004 and 2021 were retrospectively reviewed. Data on anatomical and visual outcomes, as well as preoperative, intraoperative, and postoperative variables were statistically analyzed., Results: The mean age of the patients was 31.9 ± 12.3 years. The mean follow-up time was 21.9 ± 28.3 months. The median time interval from trauma to IOFB removal was 9 days. In univariate analysis, there was a positive correlation between initial visual acuity (VA) and final VA ( P < 0.001). A higher ocular trauma score (OTS) was significantly associated with both anatomical and functional success ( P < 0.001). Linear regression analysis showed that OTS was not superior to initial VA in predicting final VA ( r = 0.625 vs r = -0.601). Anatomic and functional outcomes were not affected by the injury site, nature of PS-IOFB, or timing of PS-IOFB removal ( P > 0.05 for all). Subretinal IOFB location, the need for silicone oil tamponade, and endophthalmitis ( P = 0.005, P < 0.001, P = 0.044, respectively) were risk factors for poor visual outcome., Conclusions: The initial VA, the extent of the initial ocular damage, and the presence of endophthalmitis are important prognostic factors for functional success.

Objectives: To identify the clinical features and outcomes of early vitrectomy in patients with open globe injury (OGI) and the prognostic factors for visual outcome., Methods: This retrospective observational case series included 390 eyes in 389 patients diagnosed with OGI receiving vitrectomy within four days after injury. Preoperative parameters included the injury types, wound locations, consequent tissue damages, initial visual acuity (VA), and ocular trauma score. Postoperative outcome measures included surgical procedures, retinal (re)attachment, complications, and final VA. The logistic analysis evaluated the prognostic factors for visual outcome., Results: Intraocular foreign bodies (59.2%) and penetrating injuries (28.7%) were the most common injury types. Among the 165 eyes with retinal detachment (RD), 121 (73.3%) had retinal reattachment during early primary vitrectomy, and 32 (19.4%) were repaired during a second or subsequent surgery. Thirteen eyes (3.3%) were enucleated. The final VA improved from the initial level in 207 eyes (55.2%), remained unchanged in 123 (32.8%), and decreased in 45 (12.0%). Multivariable regression revealed that the injury zone, initial VA, RD, and endophthalmitis were associated with poor visual outcomes (P < 0.05)., Conclusions: Higher zone injury, low initial VA, RD, and endophthalmitis are predictors of poor visual outcome in eyes undergoing early vitrectomy for OGI., (© 2023.

Purpose: To analyze the anatomical and functional ophthalmic parameters after the surgical removal of various intraorbital foreign bodies., Methods: A retrospective analysis of medical records was performed featuring detailed history, ophthalmic examination, orbital computed tomographic scans, treatment details, and outcomes. The analyzed anatomical factors included extraocular movements, the position of the eyeball (proptosis, dystopia, and enophthalmos), and fullness of orbital sulci. The functional assessment was based on visual acuity, pupillary reactions, and diplopia. The outcomes were defined as complete, partial, and failure after a minimum follow-up of 1 year., Results: Of 32 patients, the organic and inorganic intraorbital foreign bodies were surgically removed from 18 (56.25%) and 14 (43.75%) orbits, respectively. At presentation, anatomically the extraocular movement restriction, proptosis/dystopia/enophthalmos, and orbital sulcus fullness were noted in 26 (81.25%), 24 (75%), and 15 (46.88%), respectively. Functionally, diminished visual acuity, diplopia, and pupil abnormalities were seen in 27 (84.38%), 14 (43.75%), and 8 (25%), respectively. After intraorbital foreign body removal at a mean follow-up of 14 months, the improvement of anatomical factors (same sequence) were observed in 8 (30.77%), 20 (83.33%), and 12 (80%), respectively. In functional factors (same sequence), the improvement was noted in none (0%), 13 (92.86%), and 5 (62.5%), respectively. Hence, the majority of patients (n = 20, 62.5%) achieved partial success, while 8 (25%) had complete success. Four (12.5%) had treatment failure despite similar management protocols., Conclusion: The anatomical outcomes are better than the functional outcomes after surgical removal of the intraorbital foreign bodies. The visual acuity does not improve considerably after the surgical removal of intraorbital foreign bodies. Overall, the wooden intraorbital foreign bodies have poorer anatomical and functional prognosis.

Purpose: To report a case of a child with strabismus and delayed discovery of a metallic intraocular foreign body with good recovery of visual acuity and stereopsis with 36-month follow-up., Methods: A 4-year-old girl was evaluated due to exotropia of right eye initiated 9 months before with progressive worsening. Visual acuity was 1.00 logMAR (20/200) in the right eye and 0.00 logMAR (20/20) in the left eye. Anterior segment evidenced a small paracentral corneal leukoma, posterior synechia and mild lens opacity in the temporal quadrant only in the right eye. Fundus examination in the right eye identified the presence of an intraocular foreign body, with appearance of metallic components surrounded by retinal pigmented endothelial cells atrophy. Full-field electroretinography (ERG) showed reduced amplitudes and delayed implicit times for both rods and cones in the affected eye. All tests were normal in the fellow eye., Results: Pars plana vitrectomy was promptly performed in the right eye, followed by phacoemulsification with intraocular lens implantation 4 months later due to worsening of the lens opacification. The full-field ERG was repeated after the surgical procedures. The ERG showed mild worsening of all responses in the right eye. After 36 months of follow-up, visual acuity was 0.20 logMAR (20/32) with improvement of the ocular misalignment and with 60 s of arc stereopsis with ERG responses unchanged., Conclusion: In this young girl perforating ocular trauma with metallic material was lately diagnosed with strabismus as a sign of alert. Prompt surgical intervention and proper management were essential to provide reasonable visual function including some degree of stereopsis, even though retinal dysfunction characterized by ERG was persistent.

An 87-year-old woman with Alzheimer's disease was referred to our eye clinic with a large corneal perforation of her right eye. On further examination a total of 15 contact lenses were found under the upper eyelid of her right eye; several lenses were also found in her left eye. During further evaluation we learned that our patient had experienced severe, recurrent and painful blepharoconjunctivitis for the past 3 years, for which she had consulted several ophthalmologists and other medical practitioners. The last time our patient had inserted a contact lens was more than 3 years previously. We therefore concluded that the retained contact lenses had caused an infectious ulcer which led to a corneal perforation. The patient underwent a perforating keratoplasty, which restored the eyesight in her right eye. Removal of the retained contact lenses gave our patient relief from her severe chronic eye pain.

Background/aim: Historic data suggest that open globe injuries should be repaired within 12-24 hours to reduce the risk of endophthalmitis. However, endophthalmitis is uncommon when systemic antibiotic prophylaxis is given. It is not clear whether delayed primary repair impacts visual outcomes in other ways or what is the optimum time to repair. We aimed to examine the effect of time to primary repair on visual outcomes., Methods: This is a retrospective comparative case series including all open globe injuries presenting to the Birmingham Midland Eye Centre between 1 January 2014 and 15 March 2016. Presenting features, mechanism of injury, visual acuity at 6-12 months and demographic data were examined., Results: 56 open globe injuries were repaired, of which sufficient data for analysis were available on 52 cases. The mean time to primary repair was 1 day after injury (range 5 hours to 7 days). Final visual acuity at 6-12 months was related to the presenting visual acuity and the Ocular Trauma Score and to the time between injury and primary repair, with a reduction in predicted visual acuity of logarithm of the minimum angle of resolution of 0.37 for every 24 hours of delay (95% CI 0.14 to 0.6)., Discussion: Open globe injuries should be repaired promptly. Presenting visual acuity remains the strongest predictor of outcome; however, delay to primary repair also reduced final visual acuity, and any significant delay from injury to repair is likely to negatively impact final visual outcome., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2019.

Background: Although full-field electroretinogram (ffERG) is the gold standard test to detect physiological dysfunction in siderosis, it measures overall retinal function. This study aims to determine if multifocal electroretinogram (mfERG) can detect subclinical siderosis in eyes with an iron intraocular foreign body (IOFB)., Methods: Twenty eyes of 20 patients with retained iron IOFB, clear ocular media and good visual acuity (≥20/120) were enroled in this prospective case-control study. The fellow eyes served as control. These were evaluated with ffERG and mfERG at baseline. Serial mfERG was done till six months after pars plana vitrectomy with IOFB removal. Primary outcomes measures were amplitude and peak time of P1 and N1 wave of mfERG., Results: The median age was 25 years (range 18-55). Most patients (n = 14/20) presented within a month of trauma. Baseline ffERG showed no difference in either 'a' or 'b' wave amplitude or peak time between cases and controls. However, on mfERG, there was a significant decrease in P1 and N1 wave amplitude and delay in P1 wave peak time in <2° retinal ring in cases as compared to controls (p = 0.001, 0.001 and 0.02 respectively) despite variability in results. At 6 months, P1 amplitude showed significant improvement from baseline in cases (p = 0.010). However, P1 peak time did not show significant recovery (p = 0.65)., Conclusions: mfERG may reveal subclinical electrophysiological retinal dysfunction in eyes with iron IOFB in cases with normal ffERG. P1 peak time may serve as an electrophysiological marker for past retinal damage.

Background: A variety of insect-related ocular injuries have been reported in the literature. However, no reports have been published documenting injuries resulting from exposure of the ocular surface to ants. This is surprising, given the relatively ubiquitous presence of ants. This is the first known case report to describe various techniques utilized in the removal of ants from the ocular surface., Case Report: This case report details the presentation of a distressed 24-year-old woman who presented to the Emergency Department with an ocular foreign body associated with pain and increased lacrimation. She was identified to have an ant adherent to her conjunctiva. Various techniques of removal were performed, with the ant finally removed without any trauma to underlying tissues., Conclusion: This is the first case report to detail various techniques utilized in the removal of ants from the ocular surface, and discusses salient features that treating physicians should be aware of in managing patients presenting with ant bites., (Copyright © 2019 Elsevier Inc.

Background: The Military Health System recognizes the importance of analyzing "foreign bodies" removed from US service members through several policy documents. This activity focuses on detecting potentially toxic metals. Intra-ocular "foreign bodies" (IOFBs) represent a small, clinically important subset. The development of ocular metallosis with iron and copper fragments is a specific local reaction to IOFBs. The results of the compositional analysis of removed IOFBs can influence clinical management decisions aimed at optimizing the preservation of sight., Method: The Joint Pathology Center (JPC) and Vision Center of Excellence (VCE) have established a pathway for the analysis of IOFBs removed from Department of Defense and Veterans Health Administration patients. The analysis of IOFBs uses analytical methods to provide information about the fragments' surface elemental and molecular composition., Results: Metallic specimens analyzed included iron and copper-containing fragments. Non-metallic IOFBs analyzed include glass, plastic (polyurethane), and nitro-cellulose fragments., Conclusion: The JPC/VCE approach to analyzing IOFBs promotes uniform handling and shipping of specimens to minimize contamination. The analytical approach allows for the characterization of IOFBs with a wide variety of compositions. The results support clinical management decisions aimed at optimal treatment for the preservation of patients' visual acuity., (Published by Oxford University Press on behalf of the Association of Military Surgeons of the United States 2019.)

Background: To identify the predictive factors for visual outcomes of patients with posterior segment intraocular foreign body (IOFB) after open-globe injury., Methods: A retrospective, interventional study was conducted to evaluate consecutive patients with retained posterior segment IOFB who underwent vitrectomy over a 10-year period from 2007 to 2016. Multivariate linear regression analysis was used to identify the potential predictive factors for final visual outcomes., Results: Forty-two patients were evaluated, with predominantly males (97.6%) and mean age 37.21 years. Hammering on metal (47.62%) was the major mechanism of injury. The majority of foreign bodies were metallic (95.24%) with a mean dimension of 4.3 mm. Twenty-four (57.14%) patients initially presented with a Snellen visual acuity <6/60. After surgery, 19 (45.24%) eyes had final visual outcomes of 6/12 or better; however, visual outcomes worse than 6/60 were documented in 17 (40.48%) eyes. Multivariate linear regression analysis revealed that the occurrence of retinal detachment (RD; p<0.01) and larger IOFB dimension (p=0.02) independently predicted worse final visual outcomes after adjusting for age and initial VA. Eyes with entry wounds located posteriorly into the sclera significantly increased the risk of RD compared to eyes with entry wounds involving cornea only (p=0.03). There was no association between time interval for IOFB removal and development of endophthalmitis., Conclusion: RD and larger IOFB dimension are significant predictive factors associated with worse final visual outcomes. Increased time to IOFB removal is not associated with either a higher risk of endophthalmitis or worse visual outcomes.

Objective: To determine the pattern of ocular injuries and their surgical management.., Methods: The retrospective study was conducted at the Chittagong Eye Infirmary and Training Complex, Chittagong, Bangladesh, and comprised hospital data of patients with ocular injuries from October 1, 2016, to December 31, 2017. Information gathered related to type and cause of injuries, visual acuity, postoperative complications, follow-up visits, and outcome. SPSS version 22 was used for data analysis., Results: Of the total injuries, 370 (91%) were classified open globe and 36 (9%) as close globe. In terms of type of injury, 330 (81.4%) were penetrating, 30 (7.3%) ruptured globe, 29 (7.1%) lime burn and 17 (4.2%) injuries were traumatic hyphaema and chemical in nature. Open globe injuries were mostly found in subjects aged 18 years or below. Surgery was the main mode of management in 388 (95.5%) patients., Conclusion: Preventive measures along with high-quality management should receive priority for reducing monocular blindness.

Background: A few case reports have described accidental eye injuries caused by fish hooks. The severity of ocular injuries is dependent on the involved ocular structures. Severe ocular injuries due to fish hooks are rare. We describe open globe and penetrating eyelid injuries from fish hooks at the Baltic Sea., Methods: Nine patients with traumatic ocular injuries caused by fish hooks were included. The following parameters were evaluated: severity of injury, best corrected visual acuity at admission and last follow-up, and surgical treatment., Results: All nine patients were male. Age ranged between 7 and 51 years with a median of 13 years. Sixty-seven percent of the patients were children. Four of the nine patients were 9 years or younger. In 5 eyes (55%) the injury was limited to the eyelid. An open globe injury was found in 4 patients (45%). The mean follow-up was 16.7 ± 32.8 months. All patients required surgical treatment. The number of operations ranged from 1 to 3, with a mean of 1.4. At admission and last follow-up, patients with eyelid injuries showed a median best corrected visual acuity (BCVA) of logMAR 0.0. Patients with open globe injuries showed a median best corrected visual acuity of logMAR 1.5 at admission, and of logMAR 0.6 at last follow-up., Conclusions: Nearly half of the patients suffered severe penetrating injuries. Especially children misjudge the risk potential of fishing due to their lack of experience. Fishing glasses should be worn not only for UV protection, but also as injury prevention strategy.

Background: To identify the clinical characteristics, prognostic factors and visual outcomes in posterior segment IOFBs patients managed by PPV in a tertiary hospital., Methods: A retrospective chart review was performed for 56 patients, who had PPV for IOFBs removal between November 2013 and November 2015. The mechanisms of injury, the nature of the IOFBs, the BCVA before and after the surgery, the penetrating site and the complications of the surgery were all collected. Univariate analyses were conducted to evaluate the prognostic factors., Results: The mean age of the patients was 36.4 years. The nature of IOFBs was mainly metal. Most injuries were commonly caused by hammering the metal. The mean preoperative VA was 2.30 logMAR, and mean final VA was 0.92 logMAR. From univariate analysis, good visual outcome was correlated with the good visual acuity before surgery and poor visual outcome was correlated with the macular break and multiple surgeries., Conclusions: In a tertiary hospital of eastern China, most cases of IOFBs were work-related. The prognosis of the patients was really well in the patients with good presenting visual acuity. Nevertheless the prognosis was not good for those patients who had macular injury or underwent several surgeries because of retinal detachment, epiretinal membrane or proliferative vitreous retinopathy. Good facilities for eye protection are urgently in demand for the workers indeed.

Purpose: We update the incidence of intraocular foreign bodies (IOFB) in soldiers admitted to Walter Reed Army Medical Center from 2001 to 2011 after sustaining combat injuries in Operation Iraqi Freedom and Operation Enduring Freedom., Design: This consecutive retrospective case series included 890 eyes of 652 patients., Methods: Data were collected in the Walter Reed Ocular Trauma Database. Inclusion criteria were any American soldier or Department of Defense civilian with an IOFB injured in Operation Iraqi Freedom/Operation Enduring Freedom. Closed globe injuries with orbital foreign bodies, injury outside of a combat zone, or non-Department of Defense civilian trauma were the exclusion criteria., Main Outcome Measures: Primary outcome measures were final visual outcome and the number, size, and location of IOFBs. Secondary outcome measures included surgical procedures, use of eye protection, associated complications, source of injury and Ocular Trauma Score., Results: There were 890 eye injuries in 652 patients evacuated to Walter Reed Army Medical Center between 2001 and 2011. IOFBs were found in 166 eyes of 149 patients (18.6%; 95% confidence interval [CI], 16.2%-21.3%). Most patients had a single IOFB (80.7%). An IOFB was positively associated with Ocular Trauma Score grade 1 or 2 (0-65) injuries (odds ratio [OR], 1.58; 95% CI, 1.07-2.38; P = 0.01). There were 130 eyes (78.33%) that had recorded time from initial visual acuity to final visual acuity and it ranged from 8 to 2421 days (mean, 433.24 days). Thirty-eight (25.16%; 95% CI, 18.89%-32.67%) eyes had no change in visual acuity, 98 (64.90%; 95% CI, 57.00%-72.07%) had improved visual acuity, and 15 (9.93%; 95% CI, 6.01%-15.84%) had decreased visual acuity. IOFB was not found to predict final visual acuity of <20/200 in multivariate analysis when other injury features were known (P = 0.1). Pars plana vitrectomy was completed on 124 eyes (74.70%). Removal of IOFB was performed in 118 eyes (71.08%; average of 31.67 days after initial injury) with a delayed procedure occurring after primary closure and antibiotics owing to a lack of surgical capacity in Iraq and Afghanistan. Retinal detachment occurred in 48 eyes (28.92%) and proliferative vitreoretinopathy in 44 eyes (26.5%)., Conclusions: IOFBs occur frequently in combat ocular trauma and are significantly associated with more severe injuries. However, IOFBs were not found to be a significant risk factor for visual acuity of <20/200., (Published by Elsevier Inc.)

Purpose: The aim of this paper was to report the outcomes of prophylactic chorioretinectomy in open-globe injuries where a foreign body penetrated the choroid or perforated the globe., Methods: We conducted a retrospective, consecutive, noncomparative, and descriptive study of patients registered in the ocular trauma database between January 2006 and December 2014, who underwent vitrectomy with chorioretinectomy., Results: Thirty-six patients (33 male, 3 female) with a mean age of 40 years and a median of follow-up of 13 months were included. Twenty-one cases had penetrating globe injuries with an intraocular foreign body and 15 cases had perforating globe injuries. A concomitant chorioretinectomy was performed in all eyes, although it was only partial in 8 eyes. At the end of follow-up, proliferative vitreoretinopathy (PVR) rates were 6.5%, anatomical success was 80.6%, and the globe survival rate was 96.8%., Conclusion: Prophylactic chorioretinectomy is a surgical procedure that may decrease posttraumatic PVR, thus improving final visual acuity and increasing globe survival rates., (© 2018 S.

A 30-year-old patient went to the emergency department because of a chemical burn to the left eye more than 10 days ago by toilet cleanser. Surprisingly, a small piece of glass was found in the inferior anterior chamber in the same eye. The visual acuity was counting fingers. There was conjunctival congestion, corneal oedema and Descemet's membrane striae. And there was also a corneal leukoma around 4 to 5 o'clock. Through repeated questioning he recalled that he was injured by an exploded light bulb around 21 years ago. He was asymptomatic until he saw "something moving" in front of the left eye one month ago. Computed tomography (CT) scanning, ultrasonography, ultrasound biomicroscopy (UBM), anterior segment optical coherence tomography (AS-OCT) verified the presence of multiple intraocular foreign bodies (IOFBs) in the anterior chamber and vitreous cavity. B-scan verified the IOFB in the vitreous cavity. Thus, he was diagnosed with corneal chemical burn, IOFBs and corneal leukoma of the left eye. The IOFB in the anterior chamber was removed through surgery. An attempt was made to remove the IOFB in the vitreous cavity with electromagnet, but it was not successful. Vitrectomy could not be performed as it was hindered by the opacity of cornea. After surgery, the visual acuity remained counting fingers and the corneal oedema still existed. This case is a reminder that a detailed history taking, a thorough physical examination and modern imaging techniques are beneficial for establishing the diagnosis and treatment of IOFBs., (Copyright © 2017 British Contact Lens Association.

Purpose: To emphasize the importance of early detection and radiologic evaluation of retained organic foreign bodies (FBs) in orbital or orbitocranial penetrating injuries by pencil., Design: Retrospective case series., Methods: A retrospective chart review of patients who had penetrating orbital or orbitocranial trauma at 2 tertiary hospitals was conducted. Patients whose mechanism of injury was penetrating trauma by pencil were included. The patients' demographics, time between initial trauma and detection of foreign body, radiologic images, and resulting sequelae were reviewed., Results: Four patients were included in this study. All patients were male; 3 were less than 2 years of age and 1 was 34 years old. Accidents were witnessed in 2 cases, and initial detections of FBs were delayed in 3 cases, from 2 days to 7 weeks. Three cases involved the right orbit. Computed tomography (CT) imaging of the head demonstrated penetration of the orbital walls in 3 cases. Three-dimensional CT scans were used to differentiate the penetrating graphite pencil fragments from the orbital wall, and catheter angiography was used in 1 case of suspected orbital apex penetration. Vision was lost in 1 patient while other severe neurologic deficits were fully recovered after removal of FB., Conclusions: Penetrating injury by pencils to the periorbital structures and delayed detection of retained pencil fragments can result in threat to life and vision. Radiologic examinations are essential to the detection of these retained FBs. Prompt detection and removal of the FBs within 48 hours and treatment with antibiotics can save vision and life., (Copyright © 2017 Elsevier Inc. All rights reserved.)

Background: Open globe injuries (OGIs) account for 44% of the cost of ocular trauma within Australia. It is estimated that 90% of ocular trauma is preventable. However, there have been few epidemiological studies within Australia that have identified groups at risk of OGIs specifically. The aim of our study was to review the epidemiology of OGIs presenting to a tertiary referral eye hospital in Australia., Methods: The Birmingham Eye Trauma Terminology (BETT) system was used to classify injuries as globe ruptures, penetrating eye injuries (PEIs), intraocular foreign bodies (IOFBs) or perforating injuries. Demographic data, past ocular history, mechanism of trauma, ocular injuries, and best-corrected visual acuity (BCVA) before and after treatment were recorded., Results: The 205 OGIs included 80 globe ruptures, 71 PEIs, 48 IOFBs and six perforating injuries. Falls predominated in older age groups compared to the other mechanisms of injury (p<0.0001). A fall was responsible for 33 globe ruptures and 82% of these had a history of previous intraocular surgery. Globe rupture and perforating injuries had poorer visual outcomes (p<0.05), consistent with previous studies. Alcohol was implicated in 20 cases of OGI, with 11 of these due to assault. PEIs and IOFBs commonly occurred while working with metal. BCVA was significantly worse following removal of an intraocular foreign body. We found presenting BCVA to be a good predictor of BCVA at the time of discharge., Conclusions: The causes of OGI varied in association with age, with older people mostly incurring their OGI through falls and younger adults through assault and working with metal. Globe ruptures occurring after a fall often had a history of intraocular surgery. The initial BCVA is useful for non-ophthalmologists who are unfamiliar with the ocular trauma score to help predict the BCVA following treatment., (Copyright © 2017 Elsevier Ltd.

[b]Abstract Objective.[/b] The aim of the study is to present four cases of lawn mowers injuries as a cause of serious visual acuity impairment. [b]Materials and Method[/b]. A retrospective study of four patients admitted in 2013-2015 to the Department of Vitreoretinal Surgery in Lublin with severe open or closed globe injury, one with an intraocular foreign body (IOFB). The presence of eye protective equipment was assessed, as well as visual acuity, eye tissue condition before and after treatment, and applied therapy., Results: In all cases an improvement was achieved in local conditions. The intraocular foreign body was removed, wounds sutured and damaged tissues placed in position. All eyeballs were saved. In three cases, visual acuity was improved to a usable level. Three patients underwent pars plana vitrectomy, one with IOFB removal from the vitreous cavity. [b]Conclusions[/b]. Lawn mower induced eye injuries are a significant cause of serious visual acuity impairment or blindness. The presented study shows that lawn mower eye injuries are still a therapeutic, social and economic problem, yet are very preventable with proper eye protection and patients' education. Current prevention strategies are inadequate, and therefore should be updated.

Purpose: To analyze the data of patients who underwent vitreoretinal surgery due to intraocular foreign body (IOFB) injuries that occurred in the Syrian civil war., Methods: Seventy-eight eyes of 78 patients who underwent vitreoretinal surgery due to IOFB injuries that occurred during the Syrian civil war were analyzed., Results: Forty-four eyes (56.4%) had traumatic cataract, 44 (56.4%) had retinal tears, 42 (53.8%) had vitreous hemorrhage, 18 (23%) had retinal detachment, 12 (15.3%) had endophthalmitis, and eight eyes had hyphema (10.2%). IOFBs consisted of metal in 62 eyes (79.4%), stone in eight eyes (10.2%), organic material in four eyes (5.1%), and glass in four eyes (5.1%). Approximately 86% of the eyes had initial VAs of 4/200 or worse. However, VAs improved in 64 eyes (82%) after the surgeries., Conclusions: Despite delays in treatment and the severity of injuries, 82% (64/78) of the eyes had an improvement in VA after the surgeries.

Aims: To describe and identify clinical characteristics, prognostic factors and visual outcome in patients with intraocular foreign bodies (IOFB) in southern Israel., Methods: We conducted a retrospective review of all cases of open globe injury with IOFB treated and followed-up for at least 6 months in the Ophthalmology Department at Soroka University Medical Center, Beer Sheva, Israel, from 1995-2011. The study population was subdivided into two groups: 1. Patients whose difference in visual acuity (VA) between presentation and end of follow-up was considered "successful" (n = 54); 2. Patients whose difference in VA between presentation and end of follow-up was considered "non-successful"(n = 14). Comparing these two groups, we analyzed the following: time from trauma to admission, time from admission to operation, location of IOB, wound zone, best corrected VA at admission., Results: A total of 97.1% of the study group were males and the mean age was 28.7 ± 15.3 years. Metallic IOB were found in 73.5% of cases. The IOFB penetrated at Zone 1 in 61.8% cases, and were located at the posterior segment in 65.2 % of cases. The two subgroups differed in their best corrected VA (by LogMAR) at presentation (p value = 0.02): the patients who were defined as "successful" (n = 54) had.a higher mean VA (1.2 ± 1.3) than those (n = 14) who were defined as "non-successful" (1.1 ± 0.6). The duration of time from trauma to admission was not found to be of statistical significance (p value = 0.361, and neither did the time from admission to operation (P value = 1)., Conclusion: We present an innovative definition of VA changes during the follow-up period in patients with open globe injuries involving IOFB. Our study showed that patients who presented with worse VA had a better chance of a "successful" outcome.

Purpose: To report outcomes of retinal detachment (RD) repair following posterior open globe injury., Methods: This retrospective, consecutive case series examined patients who underwent RD repair following Zone II and/or III open globe injury repair between January 1, 2007 and October 31, 2013. Patients with <3 months of follow-up since their last vitreoretinal surgery, and those who underwent pars plana vitrectomy (e.g., for intraocular foreign body) during their initial open globe injury repair were excluded., Results: Of 30 patients who met inclusion criteria, reattachment of the retina was achieved in 25 (83%) during the first vitreoretinal surgical procedure and 5 (17%) were deemed inoperable intraoperatively. Ten patients (30%) developed recurrent RD, and 8 underwent additional surgery. At last follow-up, reattachment was observed in 4 of these 8. The overall rate of final reattachment was 63% (19 patients). The mean number of surgeries for RD was 1.5 (range, 1-3). Fifteen patients (50%) achieved final visual acuity of counting fingers or better. Mean follow-up from the last vitreoretinal surgery was 23 months (range, 3-52)., Conclusion: Although RD following posterior open globe injury confers a grave prognosis, successful anatomic reattachment of the retina was achieved in the majority of patients in this series, with half achieving ambulatory vision.

Objectives: To report the clinical features of ocular injuries associated with explosive military ammunition in insurgent attacks in Turkey., Methods: The medical records of 48 casualties who were treated for ocular injuries sustained in insurgent attacks at the Combat Region Hospitals in Turkey were retrospectively reviewed. The reviewed data included initial visual acuity, type of explosive military ammunition (ie, improvised explosive device, mine, hand grenade and rocket-propelled grenade), type of globe injury (open-globe vs closed-globe injury), traumatised globe zones, the presence/absence of an intraocular foreign body, medical interventions, status during the explosion and injuries to other parts of the body. The visual acuity differences between different explosive materials and between 'on-foot' and 'inside-vehicle' casualties were investigated., Results: A total of 83 injured eyes were analysed. The mean patient age was 24.5±6.6 years. The mean initial logarithm of the minimum angle of resolution visual acuity was 0.60±0.63. The injuries were due to improvised explosive devices in 28 cases (58.3%), land mines in 16 cases (33.3%), and hand grenades and rocket-propelled grenades in 2 cases each (4.2%). Forty-seven eyes (56.6%) had open-globe injuries. The most frequently involved zones were zone 1 (50.0%) in closed-globe injuries and all zones (31.9%) in open-globe injuries. Intraocular foreign bodies were present in 45/47 (95.7%) eyes with open-globe injuries. Twelve (14.4%) eyes with no light perception were enucleated, and two (2.4%) eviscerated. The difference in the visual acuities between the on-foot and inside-vehicle casualties and between the injuries that were caused by the different types of explosive ammunitions was also insignificant (p=0.271 and 0.394, respectively)., Conclusions: The clinical results for eye injuries caused by explosive military ammunition sustained during insurgent attacks in Turkey are disappointing irrespective of the explosive material. The use of protective eyeglasses might improve the outcomes and should be encouraged., (Published by the BMJ Publishing Group Limited.

Background: Careful surgical management of traumatic wounds is important in open globe injury repair. This study examines the clinical outcomes following repair of open globe injuries with particular focus on wound-related issues., Design: Retrospective, cohort study of consecutive open globe injuries presenting to a tertiary referral eye hospital from 1 January 2009 to 31 December 2011., Participants: A total of 267 eyes of 263 patients, mainly male (82.5%) with a mean age of 44.8 (range: 4-97) years. Average follow up was 6.9 months., Methods: All cases classified according to Ocular Trauma Classification Group., Main Outcome Measures: Visual outcomes, risk factors for and rates of postoperative complications and endophthalmitis., Results: There were 83 globe ruptures, 182 penetrating and 2 perforating eye injuries, of which 43 cases had intraocular foreign body. Factors contributing to final visual acuity (VA) <6/60 were poor presenting VA (odds ratio [OR] = 16.0, 95% confidence interval [CI]: 4.81-53.1), globe rupture (OR = 4.64, [1.99-10.8]), retinal detachment (OR = 3.40, [1.19-9.74]) and age ≥50 (OR = 2.45, [1.05-5.74]). Wound leak occurred in 44 eyes (16%). Of these, 18 (41%) proceeded to re-suturing. Factors contributing to wound leak were stellate-shaped wound (OR = 3.28, [1.39-7.73]) and delayed presentation (OR = 2.80, [1.02-7.71]). Ten eyes (3.7%) developed endophthalmitis. Factors associated with endophthalmitis were delayed presentation (OR = 8.91, [1.71-46.6]), microbial keratitis (OR = 12.5, [1.85-85.0]) and lens capsule breach (OR = 12.4, [1.85-83.1])., Conclusions: Wound leak is an important postoperative complication of open globe injury repair. Delayed presentation is an important risk factor for postoperative wound leak and endophthalmitis. Prompt and meticulous wound management of open globe injury may reduce these complications., (© 2015 Royal Australian and New Zealand College of Ophthalmologists.)

Background: To evaluate the morpho-functional outcomes and safety of transconjuctival 23-gauge pars plana vitrectomy(PPV) for removal of intraocular foreign bodies (IOFBs)., Methods: A retrospective study of 36 consecutive cases (mean age; 34,2 ± 10,9 years (between 15 and 60), 27 M,9 F) of 23-G PPV for the removal of IOFBs during the period of April 2009 and December 2011 and followed 9,4 ± 6,4(2-27) months were conducted. Visual outcomes, slit lamp biomicroscopy, intraocular pressure (IOP), and posterior segment visualization by indirect ophthalmoscopy, A-B mode ultrasonography, and computed orbital tomography were performed for all cases. Main outcomes including anatomic and visual outcomes, and both intraoperative and postoperative complications were recorded., Results: Of the 36 cases available for the study, the IOFBs (size range, 3 to 12 mm) could be removed in all eyes. Mean preoperative LogMAR BCVA was 1.44 ± 138 (range, 1.00 to 0.00) and mean postoperative LogMAR BCVA at final visit was 0,78 ± 0,98 (range, 1.00 to 0.00). (P = 0,007) Anatomic success was obtained in 97.2 % of eyes. 16 patients needed primary wound repair due to the leakage in insertion sites before the PPV, however remaining 20 cases were not. Fibrin reaction was seen in 8 (22.2 %) patients in early postoperative period, intraocular pressure elevation was detected in 12 (33.3 %) patients in which the silicone oil was used as an intravitreal tamponade, one patient with silicone oil tamponade developed band keratopathy and phthisis bulbi., Conclusions: 23-Gauge PPV is a feasible, effective approach in the surgical management of the patients with posterior segment intraocular foreign bodies.

Purpose: To analyse the postoperative anatomic and functional outcomes in addition to complications after vitreoretinal surgery for patients with shotgun eye injuries related to hunting accidents., Materials: Retrospective review of the clinical records of all cases of shotgun eye injuries presented between January 2000 and January 2011 and with a minimum follow-up of 1 year. Collection of demographics, type of injury, choice of management, complications and final surgical success with final visual acuity is reported., Results: Twenty eyes of 19 patients (all male) with a mean age of 36.1 years (range 16-60 years) were included in the study. Mean postoperative follow-up was 47.5 months (range 15-118 months). Best corrected visual acuity (BCVA) at presentation ranged from perception of light to 20/200. Ten eyes had a penetrating injury and 10 others had a perforating injury. All the eyes underwent an initial vitrectomy and the intraocular pellet was removed in all the 10 penetrating injuries. Concurrent cataract surgery was performed in 12 cases, internal tamponade was used in 15 cases and a supplemental encircling scleral buckle was inserted in 12 cases. One additional vitreoretinal surgery was required in seven cases (35%) and two additional surgeries required in two other cases (10%). At last follow-up BCVA ranged from NPL to 20/20 and was 20/100 or better in 10 eyes (50%). All patients had a flat retina except for two cases (10%) that developed severe proliferative vitreoretinopathy., Conclusion: These results suggest that vitreoretinal surgery can offer good visual rehabilitation in patients with shotgun eye injuries.

Purpose: To report the use of femtosecond laser platform to remove a glass foreign body (FB) and remove scar by performing sutureless lamellar keratoplasty., Case Report: A 34-year-old man presented with a posttraumatic anterior stromal scar and retained corneal glass FB after injury to his left eye, sustained in a prior vehicular accident. Right eye examination was essentially normal. Best-corrected visual acuity of the left eye was 20/320. He underwent femtosecond laser-assisted sutureless anterior lamellar keratoplasty using the 500-kHz femtosecond laser machine. The host bed and donor lenticule diameters were 7.9 and 7.8 mm and the thickness of the lenticule was 125 and 150 μm, respectively. The recipient lenticule was obtained by placing the lamellar incision that encompassed the FB. When the recipient lenticule was lifted, partially embedded FB present in the stroma was removed after dislodging it with a 26-gauge needle. The femtosecond-dissected donor button was placed onto the stromal bed with a snug fit. No sutures were taken. Postoperatively, best-corrected visual acuity improved to 20/50 at 1 month and 20/30 at 7 months of follow-up., Conclusions: Femtosecond laser-assisted sutureless anterior lamellar keratoplasty is a promising modality for lamellar keratoplasty, and as the depth of the incision can be obtained with precision, impacted stromal FBs can be removed in a single procedure along with scars.

Purpose: The purpose of this study was to evaluate the need for close follow-up after removal of noncomplicated corneal foreign bodies., Methods: This is an observational prospective cohort study of 60 eyes in noncontact lens wearers with corneal foreign bodies outside the visual axis. Foreign bodies were removed and patients were followed as per the Wills Eye Manual guideline for 1 to 3 days after foreign body extraction, and every 3 to 5 days until resolution of the epithelial defect. Patients were asked to record their symptoms of eye pain, eye irritation, eye redness, and visual acuity on a visual analog scale to monitor symptoms related to development of infectious keratitis. The primary endpoint was resolution of the epithelial defect., Results: The average time to resolution of the epithelial defect was 4.34 ± 1.56 days, with an average of 2.2 ± 1.23 follow-up visits after removal. One patient developed infectious keratitis (1.67%). Symptoms showed a statistically significant improvement in patients who had healed epithelial defects, and a statistically significant worsening in the 1 patient who developed infectious keratitis (sensitivity = 1 and specificity = 0.915)., Conclusions: Few noncomplicated injuries develop infectious keratitis. We recommend fewer follow-ups for these injuries. However, if patients develop any worsening in eye pain, irritation, redness, or decrease in their visual acuity, they should return promptly for reassessment.

Purpose: To study the outcome of removal of retained intraocular foreign bodies (RIOFBs) via limbus using 23-gauge transconjunctival sutureless vitrectomy (TSV)., Materials and Methods: In this prospective, non-comparative interventional case series, fourteen eyes of 14 patients fulfilling the inclusion criteria were enrolled. They underwent 23-gauge TSV for management of posterior segment RIOFB and reviewed at 1 day, 7 days, 6 weeks, 3, 6 and 12 months. Eyes with penetrating eye injury involving cornea or limbus (corneal injury not so severe to hinder vitrectomy), cataract associated with anterior and/or posterior capsular tear requiring cataract surgery and posterior segment RIOFB with minimal posterior segment involvement were included. Main outcome measures include success in removal of RIOFB without enlarging sclerotomy, ability to preserve capsular support, improvement in visual acuity and complications, if any., Results: All eyes underwent the successful RIOFB removal through limbal port without enlarging scleral ports. None of the eyes required suturing of the sclera, cornea or conjunctiva. Anterior capsular rim could be preserved in all eyes except one. Postoperatively follow up ranged from one year in 8, 6 months in 4 and 3 months in 2 eyes. The mean logMAR visual acuity at 3, 6, and 12 months showed significant improvement. There were no intraoperative complications. Postoperative complications include microscopic hyphema and loose blood in vitreous cavity in one eye., Conclusion: The advantages of 23-gauge TSV for removal of RIOFB may be passed on to select cases. RIOFB removal through limbal route obviated the need for scleral port enlargement and preserved capsular support for early visual rehabilitation.

Purpose: To evaluate the evolution of the best-corrected visual acuity (BCVA), to determine the prognostic factors, and to analyze the efficiency of the surgical procedures in the cases of ocular injuries caused by a metallic intraocular foreign body retained in the posterior segment as a result of hammering., Methods: A retrospective review of 64 consecutive patients was conducted at the Cantonal Hospital St Gallen over a 15-year period. The pre-, intra-, and postoperative clinical parameters were assessed. The statistics were performed using Fisher's exact test and a multiple correspondence analysis., Results: The mean initial BCVA was 20/138 (standard deviation, 20/112). The mean ocular trauma score was 3.03 (standard deviation, 0.83). In all cases, the removal of the intraocular foreign body was performed within 24 hours after the injury. In 45 patients (70.3%), further operations were performed during the mean follow-up of 54.4 months (standard deviation, 22.7 months). The mean final BCVA was 20/39 (standard deviation, 20/55). In 53 patients (82.8%), the final BCVA was 20/40 or more. In 8 patients (12.5%), the final BCVA was 20/200 or less because of a direct macular lesion caused by the intraocular foreign body (P < 0.001)., Conclusion: Thanks to the improvement in the surgical procedures, the ocular injuries with a metallic intraocular foreign body in the posterior segment as a result of hammering have a good visual outcome unless the macula is involved.

Background/aims: To assess the predictive value and the applicability of Ocular Trauma Score (OTS) for paediatric injuries., Methods: Retrospective case series of 71 open globe injuries in children less than 18 years of age with a minimum follow-up period of 1 year. The variables of the OTS, the Paediatric Penetrating OTS (POTS), lens injuries and anterior versus posterior segment injuries were analysed for their predictive values in terms of visual outcome. The applicability and the predictive values of OTS and POTS as a whole were then evaluated., Results: Initial visual acuities, retinal detachments, wound locations (p<0.001 each), lens injuries (p=0.001), posterior segment injuries (p=0.002), traumatic cataracts (p=0.010), hyphaema (p=0.011) and vitreous haemorrhages (p=0.026) had significant impacts on visual outcome. The application of OTS proved difficult, as the presence of a mild degree of a relative afferent pupillary defect (RAPD) could not accurately be evaluated in all of our patients. Calculating the OTS without evaluation of RAPD renders it easily applicable for the initial examinations while remaining significantly prognostic (p<0.001). The predictions of the POTS correlated with the actual final visual acuities (p<0.001), but several POTS variables (ie, iris prolapse, age, organic injuries and delay of surgery >48 h) had only limited impacts on visual outcome., Conclusions: The OTS has a high predictive value for visual outcome after open globe injuries in children, even without evaluation of RAPD.

Context: Severe pediatric ocular injury remains a frequent and difficult problem. Vitrectomy is a major technique that has been used to manage severely damaged eyes. However, limited follow-up studies exist currently., Aims: To evaluate the clinical features and predictive factors of visual and anatomic outcomes in Eye Injury Vitrectomy Study (EIVS)., Settings and Design: Retrospective, consecutive, interventional case series., Materials and Methods: Reviewing and analyzing records of children, aged 15 years or younger, who had undergone vitrectomy for eye injuries in EIVS database between January 1997 and December 2009., Statistical Analysis Used: Descriptive analyses and multiple Logistic regressions were employed for all variables using SPSS software (version 17.0, SPSS Inc.)., Results: Eighty-seven children (89 eyes) with more than 6 months follow-up and complete records identified in EIVS were included in this study. Average follow-up was 12.7 months. The mean age was 9.4 ± 3.8 years. Seventy-seven eyes (86.5%) had open globe injuries, and 12 (13.5%) had closed globe injuries. Seventeen eyes (19.3%) presented with endophthalmitis. Seventy-five eyes (88.2%) presented with visual acuity of 4/200 or worse; however, 42 eyes (47.7%) achieved 4/200 or better vision with anatomical restoration after vitrectomy. Multiple analysis showed that choroidal damage, large scleral wound, and endophthalmitis were significantly associated with unfavorable outcome, the OR values were 16.7 (95% CI: 2.7-102.4, P = 0.002), 10.9 (95% CI: 1.7-71.6, P = 0.013), and 6.6 (95% CI: 1.0-42.4, P = 0.048), respectively., Conclusions: Vitrectomy intervention resulted in favorable visual and anatomic outcomes in almost half of the injured eyes. Choroidal damage, large scleral wound, and endophthalmitis were the prognostic indicators of unfavorable outcome.

Purpose: To identify prognostic factors related to ruptured and lacerated globes and compare the visual outcomes of these 2 mechanisms of injury., Methods: Medical records of patients with open-globe injuries referred to the Goldschleger Eye Institute between 2004 and 2010 were reviewed. Clinical parameters were summarized as defined by the ocular trauma score (OTS). All cases were classified as either ruptured or lacerated globes and a statistical analysis was performed in order to identify prognostic factors., Results: Medical records of 73 patients (55 male) were reviewed. Mean age of male injured patients was 33 years and of female injured patients was 64 years. Thirty-three percent of injuries were classified as ruptured globes. Males were mostly injured by a lacerating mechanism, compared to females (79.6% and 33.3%, respectively; p = 0.01). Mean logMAR at presentation after lacerated and ruptured globes was 1.42 ± 1.01 and 2.02 ± 0.91, respectively. Mean logMAR at the final follow-up visit after lacerated and ruptured globes was 0.65 ± 0.85 and 1.69 ± 1.10, respectively. Mean logMAR of the lacerated globes improved to a better extent compared to the ruptured ones (p = 0.046). The OTS was found to be a significant predictor of final mean logMAR for the lacerated globes (p<0.001), whereas mean logMAR at presentation was found to be the only predictive measure for ruptured globes (p<0.001)., Conclusions: Ruptured and lacerated globes differ from each other in regard to prognostic factors and visual outcomes. We recommend distinguishing these 2 injury types in clinical practice as different open-globe injuries.

Purpose: To report new findings in a case of ocular siderosis explored by high resolution angiography and adaptive optics (AO)., Methods: We report data on a 40-year-old man with an intraocular foreign body (IOFB) embedded in the sclera after hammering., Results: Nine months after this accident, the patient presented with full-field electroretinogram (FF-ERG) abnormalities. Subsequent IOFB extraction was performed. One month after the surgery, high resolution angiography showed for the first time small iron particles all over the inner retinal surface. Spreading of these deposits was followed by inflammatory prepapillary new vessels and venous retinal vasculatis, which spontaneously resolved within a few months. ERG responses became slightly electronegative at this time. Clearance of the iron particles was followed over a year with AO and ERG recording. AO revealed an arterial tropism with a decrease in the amount of particles overtime, which may be consistent with macrophagic activity., Conclusion: High resolution angiography and AO are new tools, combined with electrophysiology, to better understand ocular siderosis pathophysiology.

The penetration of objects into the orbit can lead to blindness and even to the death of the patient. The penetration of organic objects longer than 7 cm into the eye is a rare phenomenon. In this study, we report a case in which a 6-year-old boy fell on a pencil which penetrated the upper side of his right eye orbit. Because of the agitation of the child and the lack of access, it was not possible to perform a brain or orbital computed tomography (CT) scan, but an X-ray showed that the object had gone directly into the retro-orbital space. As the result of a clinical diagnosis, it was possible to ascertain that the globe was severely hypertonic. Throughout this process the child was extremely agitated. After consultation with the neurosurgery service, the patient was rushed to the operation room. After anesthesia and superanasal peritomy, the pencil was removed slowly from the orbit. Neurology and CT scans after surgery didn't show any ocular or brain symptoms. Once the patient's general condition had improved sufficiently and his visual acuity had returned to 10/10, he was discharged from the hospital. This case shows that even without specialized tests, such as CT scans, an organ can be saved., (© 2014 KUMS, All rights reserved.)

Purpose: To evaluate the visual and anatomic results and determine the prognostic factors after pars plana vitrectomy and posterior segment intraocular foreign body (IOFB) removal., Materials and Methods: This retrospective study reviews the patients' charts of 48 consecutive patients with posterior segment IOFB who underwent pars plana vitrectomy and IOFB removal over a 4-year period, recently. Association between visual outcome and various preoperative, operative, and postoperative variables was statistically analyzed. Data were analyzed with the paired t-test and the chi square test. Statistical significance was indicated by P < 0.05., Results: The mean interval between the time of injury and IOFB removal was 24 ± 43.1 days and 27 (53%) eyes underwent IOFB removal within 7 days of the injury. Nine (19.1%) patients achieved a visual acuity of 20/40 or better. An improvement of visual acuity of at least three lines occurred in 21 (44.6%) eyes and the vision remained unchanged in 15 (31.9%) eyes. Postoperative retinal detachment occurred in five (10.6%) eyes. Visual improvement was more likely to occur in eyes with lower levels of presenting visual acuity (P = 0.2). Visual improvement was not associated with an entry site and IOFB location, lens injury, time to surgery, and pre- and post-operative retinal detachment. At the end of follow up, anatomical success was achieved in 97.9% of eyes., Conclusions: High anatomical success could be achieved after the removal of posterior segment IOFBs by vitrectomy, despite a delay in surgery. Poor visual outcome may be mainly due to the initial ocular injury.

Background and Objective: To examine the outcomes of vitrectomy in ocular trauma with opaque cornea., Patients and Methods: This retrospective study included 17 eyes of 16 patients who underwent vitrectomy with temporary keratoprosthesis or endoscopy at Walter Reed Army Medical Center, Washington, DC, from March 2003 to October 2010., Results: A temporary keratoprosthesis was used in 8 eyes (47%) and endoscopy in 9 eyes (53%). Overall, the number of eyes with visual acuity of 20/200 or better improved from 0 at baseline to 5 (29%) at 6 months. The number of eyes with retinal detachment also improved from 10 (59%) at baseline to 3 (18%) at 6 months., Conclusion: Vitrectomy may be safely performed in ocular trauma with opaque cornea using a temporary keratoprosthesis or endoscopy with comparable outcomes. Endoscopy allows earlier diagnosis and treatment of occult pathology and requires less time and fewer procedures to implement than the temporary keratoprosthesis., (Copyright 2012, SLACK Incorporated.)

A technique of foreign body removal from optic nerve head performing an external approach and optic nerve transection is described. After 3 months of follow-up cosmetic result is satisfactory and there are no surgery related complications.

Purpose: The timing of vitrectomy for severe penetrating eye injury to the posterior segment remains controversial; this is particularly pertinent if patients are children and young adults. We present our results of the surgical procedure in young patients after penetrating eye injury using a delayed approach., Methods: Noncomparative interventional study of patients up to 29 years of age who had vitreoretinal surgery for penetrating eye injury. Surgical procedure was performed in seven eyes of six patients. Posterior vitrectomy was performed because of hemophthalmos after waiting for a mean of 49 days (range, 17-90 days) after posterior vitreous detachment was confirmed on ultrasound examination., Results: The mean postoperative follow-up period was 22 months (range, 9-35 months). Of the 7 patients, 6 (85.7%) achieved visual acuity (Snellen acuity) of 6/12 or better and 4 eyes (57.1%) reached 6/6. At the last follow-up, all patients were pseudophakic, 2 required secondary lens implants, and retinal detachment developed in 1 patient., Conclusion: This consecutive case series underlines the fact that a delayed approach is compatible with good visual prognosis in relatively young patients.

Purpose: To investigate epidemiologic and clinical characteristics, prognostic factors, and visual outcomes of posttraumatic intraocular foreign body (IOFB)., Design: Retrospective, consecutive case series., Methods: Information from 1,421 eyes (1299 inpatients) with IOFB selected from all open-globe injury cases (4,968 eyes of 4,865 inpatients) in 15 tertiary hospitals in China over a 5-year period were collected from a standardized preformulated database of eye injuries. Factors affecting retinal lesions or detachment, development of endophthalmitis, and visual outcome were analyzed statistically., Results: IOFBs represented 28.60% of all open-globe injuries. Of the 1,421 eyes, endophthalmitis developed in 232 (16.76%), and independent protective factors included primary repair within 24 hours (odds ratio [OR], 0.59; P = .006) and self-sealing wounds (OR, 0.69; P = .013). At discharge or follow-up, the enucleation rate was 7.53%, best-corrected visual acuity (VA) improved in 54.33%, and 4.85% had no light perception. Wound length of at least 3 mm and IOFB located in the posterior segment increased the risk of retinal lesion or detachment, and both (OR, 1.66; P < .001; OR, 4.04; P < .001) were significant negative predictors for visual outcome, along with wound larger than IOFB in largest length (OR, 2.38; P = .002) and endophthalmitis (OR, 2.01; P = .0003). Better initial VA (OR, 0.76; P < .001) was a protective factor for final VA., Conclusions: For IOFBs, primary wound closure by repair within 24 hours or self-sealing independently reduces the risk of endophthalmitis. Worse presenting VA, larger wounds, IOFB in posterior segment, wound larger than IOFB in largest length, and endophthalmitis predict worse visual outcome., (Copyright © 2011 Elsevier Inc.

We report a case of a retained graphite anterior chamber foreign body that was masquerading as stromal keratitis. A 28-year-old male visited with complaints of visual disturbance and hyperemia in his right eye for four weeks. On initial examination, he presented with a stromal edema involving the inferior half of the cornea, epithelial microcysts, and moderate chamber inflammation. Suspecting herpetic stromal keratitis, he was treated with anti-viral and anti-inflammatory agents. One month after the initial visit, anterior chamber inflammation was improved and his visual acuity recovered to 20/20, but subtle corneal edema still remained. On tapering the medication, after three months, a foreign body was incidentally identified in the inferior chamber angle and was surgically removed resulting in complete resolution of corneal edema. The removed foreign body was a fragment of graphite and he subsequently disclosed a trauma with mechanical pencil 12 years earlier. This case showed that the presence of an anterior chamber foreign body should always be considered in the differential diagnosis of idiopathic localized corneal edema., (© 2011 The Korean Ophthalmological Society)

Purpose: To determine the functional and anatomic outcome of early surgical repair with vitrectomy and silicone oil in open-globe injuries with retinal detachment (RD)., Design: Retrospective consecutive interventional case series., Methods: All patients with open-globe injuries with RD treated between 1997 and 2007 underwent primary repair including vitrectomy with silicone oil within 8 hours after presentation. For data analysis, patients were divided into 3 groups according to the BETT classification: Group 1, intraocular foreign body; Group 2, penetrating injury; Group 3, globe rupture. Outcome measures were final reading visual acuity (0.4 logMAR or better), final ambulatory visual acuity (1.6 logMAR or better), endophthalmitis, and postoperative proliferative vitreoretinopathy (PVR)., Results: Eighty-eight patients were included (Group 1, n = 13; Group 2, n = 36; Group 3, n = 39). Mean follow-up was 22 months (standard deviation [SD] = 23, range 6-107 months). Eight percent of patients retained reading vision without significant difference between the 3 groups. Fewer patients in Group 3 than in Group 1 or 2 retained ambulatory visual acuity (Group 1, 62%; Group 2, 64%; Group 3, 33%, P = .024). Endophthalmitis occurred in 3.4% of eyes (1 eye in each group). PVR grade B-C, type 1-3 developed in 44% of patients without significant difference between the 3 groups. Re-RD occurred in 38% of eyes., Conclusions: Few patients achieved reading vision while 50% of patients retained ambulatory visual acuity. Final visual outcome is related to the severity of the injury. The frequency of postoperative endophthalmitis is low. Postoperative development of advanced PVR is avoided in most patients., (Copyright © 2011 Elsevier Inc. All rights reserved.)

Purpose: To determine the main prognostic factors related to final visual acuity (VA) after intraocular ocular foreign body (IOFB) extraction., Methods: We performed a retrospective chart review of 80 patients (84 eyes) who underwent surgical removal of IOFBs and repair of associated ocular trauma. Data on age, gender, presenting clinical features, characteristics of IOFB, complications, interval between time of injury and IOFB removal, and final VA were recorded and analyzed., Results: Male adults were the major population affected by IOFBs. Improved vision outcome was obtained after the removal of IOFBs and surgical repair of the eyes (p=0.011). Factors showing statistical association with final VA included initial VA (p=0.000), size of IOFB (p=0.010), IOFB location inside the eye (p=0.000), and preoperative retinal detachment (p=0.011). Factors showing no statistical association with final VA included nature of IOFB (p=0.445), entrance wound location, other IOFB-related complications (such as cataract, vitreous hemorrhage, secondary glaucoma, hyphema, endophthalmitis, siderosis, and atrophia bulbi), and interval between injury and IOFB removal., Conclusions: Prognostic factors for poor final VA related to IOFBs included poor initial VA, large IOFB size, posterior segment location, and preoperative retinal detachment.

Purpose: To evaluate the characteristics and outcomes of patients treated for open globe injuries sustained at work and to compare these results to patients injured outside of work., Design: Retrospective chart review of 812 consecutive patients with open globe injuries treated at the Massachusetts Eye and Ear Infirmary between 1999 and 2008., Methods: A total of 146 patients with open globe injuries sustained at work were identified and their characteristics and outcomes were compared with the rest of the patients in the database., Results: Of the patients injured at work, 98% were men, and the average age of the patients was 35.8 years (17-72 years). The most common mechanism of injury was penetrating trauma (56%); 38 patients examined had intraocular foreign bodies (IOFB). Nine work-related open globe injuries resulted in enucleation. There was a higher incidence of IOFBs (P = .0001) and penetrating injuries (P = .0005) in patients injured at work. Both the preoperative (P = .0001) and final best-corrected visual acuity (P = .0001) was better in the work-related group. The final visual acuity was better than 20/200 in 74.1% of cases of work-related open globe injuries. However, there was no difference observed in the rate of enucleations (P = .4)., Conclusions: Work-related injuries can cause significant morbidity in a young population of patients. Based on average patient follow-up and final visual acuity, those injured at work do at least as well as, if not potentially better than, those with open globe injuries sustained outside of work. While the statistically higher rate of IOFB in the work population is not surprising, it does emphasize the importance of strict adherence to the use of eye protection in the workplace., (Copyright (c) 2010 Elsevier Inc.

Purpose: To evaluate the effect of non-penetrating corneal foreign bodies secondary to explosive blasts on the visual performance of soldiers., Methods: In a prospective, non-interventional study subjective visual performance and objective optical quality of 11 injured eyes with retained corneal foreign bodies were compared with that of 11 normal controls. Visual performance measures consisted of best spectacle-corrected high-contrast visual acuity (HCVA), low-contrast (5%) visual acuity (LCVA), and contrast sensitivity (CS). LCVA was evaluated in two luminance levels (photopic and mesopic) and two glare conditions (with and without glare). Acuity measurements were scored using logMAR notation. Objective optical quality was assessed comparing total root mean square wavefront error (WFE) and percent higher order aberrations. Modulation transfer functions calculated from the wavefront maps were used to predict the results of the psychophysical contrast testing., Results: HCVA of injured eyes (M = -0.03) did not differ significantly (t(20) = 1.56, p = 0.13) when compared with controls (M = -0.09). However, visual performance of injured eyes (M = 0.33) was significantly worse than control eyes (M = 0.11) on photopic LCVA (t(20) = 4.16, p < 0.001), mesopic LCVA(M = 0.44 vs. M = 0.21, t(20) = 3.85, p = 0.001), mesopic LCVA with glare (M = 0.49 vs. M = 0.21, t(20) = 3.66, p = 0.002), and small letter CS (M = 0.25 vs. M = 0.90, t(20) = -6.6, p < 0.001). For a 6-mm pupil, mean absolute WFE attributed to higher order aberrations for the injured eyes was 0.86 microm and 0.59 microm for the control eyes. This difference was significant (t(20) = -2.15, p = 0.044)., Conclusions: Although HCVA was no different than the normal controls, visual performance of the injured eyes was significantly worse in terms of LCVA and CS. On average, visual performance can be broadly predicted by the modulation transfer function derived from the subjects' wavefront aberration map.

Background: To report the outcomes of chorioretinectomy versus non-chorioretinectomy in combat ocular injuries where a foreign body penetrated the choroid or perforated the globe., Methods: Retrospective, comparative, consecutive interventional case series of 32 perforating or severe intraocular foreign body combat ocular trauma injuries sustained by United States military soldiers and treated at a single institution from March 2003 to March 2009. Final best-corrected visual acuity (BCVA) in 19 non-chorioretinectomy-treated eyes was compared to 13 chorioretinectomy-treated eyes. The chorioretinectomy group was repaired with a 20 gauge three-port pars plana vitrectomy (PPV) by removing the choroid and/or retina at the impact or perforation site of the foreign body following evacuation from a combat zone. The main outcome measures were best-corrected visual acuity and rates of globe survival, retina reattachment and proliferative vitreoretinopathy., Results: Thirty-two eyes of 31 patients with a mean age of 29 +/- 9 years (range, 19-53 years) were followed for a median of 463 +/- 226 days (range, 59-1022 days). The mean time of injury to the operating room in the chorioretinectomy group was 12.6 +/- 9.8 days, compared to that of the non-chorioretinectomy group of 22.1 +/- 16.4 days (P = 0.05) Final BCVA > or =20/200 occurred in seven of 13 (54%) of the chorioretinectomy group, compared to two of 19 (11%) in the non-chorioretinectomy group (P = 0.04). Globe survival rates were higher in the chorioretinectomy group [11 of 13 (85%) vs 9 of 19 (45%); P = 0.06], as well as the final retinal reattachment rate [8 of 13 (62%) vs 8 of 19 (42%); P = 0.47]. The proliferative vitreoretinopathy rate was eight of 13 (62%) in the chorioretinectomy group, compared to 14 of 19 (74%) in the non-chorioretinectomy group (P = 0.70). Graft failure occurred in five of six eyes (83%) of non-chorioretinectomy cases, requiring temporary keratoprosthesis and penetrating keratoplasty., Conclusion: Chorioretinectomy is a surgical option that may improve final BCVA and increase globe survival rates when a foreign body penetrates the choroid or perforates the globe.

Purpose: The purpose of this study was to evaluate the anatomical and functional outcomes of surgical intervention in severely traumatized eyes with no light perception (NLP)., Methods: In this prospective interventional case series, 18 eyes of 18 patients with severe ocular trauma whose vision was documented as NLP and with relative afferent pupillary defect of 3 to 4+ underwent deep vitrectomy and other appropriate procedures 1 to 3 times., Results: Vision was NLP in all eyes at the time of surgery, which was performed 3 days to 14 days after the initial trauma. During a mean follow-up period of 20.5 +/- 5.2 months (range, 11-36 months), except for 1 case of phthisis, other eyes achieved acceptable anatomical and functional outcomes. Postoperative vision was NLP in 2 eyes (11.1%), light perception in 3 eyes (16.7%), hand motions in 4 eyes (22.2%), counting fingers in 3 eyes (16.7%), and 20/200 or better in 6 eyes (33.4%)., Conclusion: After eye trauma, NLP vision and relative afferent pupillary defect of 3 to 4+ alone may not be an indication for enucleation. Performing exploratory surgery within 14 days after the injury may salvage the globe and improve vision; this approach also entails positive psychologic effects for patients and relatives.
