Molecular changes and vision loss in a mouse model of closed-globe blast trauma.

Abstract: PURPOSE. To characterize retinal changes and assess vision after an eye-directed air blast. METHODS. Adult C57Bl/6 mice were exposed to a blast directed at one eye. Optical coherence tomography and histology were performed to assess retina and optic nerve integrity. Cell death, oxidative stress and glial reactivity were examined by immunohistochemistry. Visual changes were measured by electroretinogram recordings and the optokinetic reflex. RESULTS. In the outer retina, eye blast caused retinal pigment epithelium vacuoles and rare retinal detachments followed by regional cell death. Labeling for nitrotyrosine and markers of pyroptosis (caspase-1) and necroptosis (RIP-1, 3) increased, primarily in the inner retina, after blast. Caspase-1 labeling was restricted primarily to the starburst amacrine cells. A few degenerating axons were detected at 28 days post-blast. Despite a lack of substantial cell death or decreased electroretinogram, there was a deficit in visual acuity after blast. CONCLUSIONS. Oxidative stress, neuroinflammation, and cell death became increasingly prevalent over time post-blast suggestive of an ongoing neurodegenerative response. Outer retinal changes either resolved or remained focal. In contrast, inner retinal changes were more robust and spread from focal regions to the entire retina over time post-blast. Our model of eye blast trauma causes molecular changes and a decrease in visual acuity within the first month post-blast despite a lack of overt eye injury. This subtle response matches the delayed presentation of visual deficits in some blast-exposed Veterans. Language: en

Open globe injury in Hospital Universiti Sains Malaysia - A 10-year review

Abstract: AIM: To identify the aetiology of open globe injuries at Hospital Universiti Sains Malaysia over a period of 10y and the prognostic factors for visual outcome. METHODS: Retrospective review of medical records of open globe injury cases that presented from January 2000 to December 2009. Classification of open globe injury was based on the Birmingham Eye Trauma Terminology (BETT). Records were obtained with hospital permission via the in-house electronic patient management system, and the case notes of all patients with a diagnosis of open globe injury were scrutinised. Patients with prior ocular trauma, pre-existing ocular conditions affecting the visual acuity, contrast sensitivity, central vision or corneal thickness, as well as those with a history of previous intraocular or refractive surgery were excluded. Analysis of data was with SPSS version 20.0. Ordinal logistic regression analysis was used to examine the association between prognostic factors and visual outcome. RESULTS: This study involved 220 patients (n=222 eyes). The most common place of injury was the home (51.8%), followed by the workplace (23.4%). Among children aged less than 16y of age, domestic-related injury was the predominant cause (54.6%), while in those aged 16y and above, occupational injuries were the most common cause (40.0%). Most eyes (76.5%) had an initial visual acuity worse than 3/60, and in half of these, the visual acuity improved. The visual outcome was found to be significantly associated with the initial visual acuity (PCONCLUSION: The most common causes of open globe injury are domestic accidents and occupational injuries. Significant prognostic factors for final visual outcome in patients with open globe injury are initial visual acuity, posterior extent and length of wound, presence of hyphaema and presence of vitreous prolapse. Awareness of the factors predicting a poor visual outcome may be helpful during counselling of patients with open globe injuries. Language: en

Intraorbital wooden foreign body: clinical analysis of 32 cases, a 10-year experience

Abstract: Background We aimed to describe herein the clinical features, diagnosis and treatment of intraorbital wooden foreign body injuries. Methods A case series review of orbital injuries managed at Trakya University Faculty of Medicine between 2002 and 2012 was performed retrospectively. The clinical analysis of 32 intraorbital wooden foreign body injuries was reviewed. Results Among the 32 cases, injuries in 16 were caused by a tree branch, in 10 by a pencil, in 5 by a stick, and in 1 by a bush. With respect to preoperative vision, postoperative vision was improved in 69% of patients. Time lapse from injury to presentation was correlated with the size of the foreign body. The subjects were comparable in etiological factor, and distribution of injury according to orbit was as follows: superior 28%, medial 25%, lateral 22%, inferior 16%, and posterior 9%. Computerized tomography (CT) for foreign body was definitive in 72% (n=23) and suggestive in 28% (n=9). Conclusion The diagnosis of orbital wooden foreign body is difficult because it may be missed clinically and from the imaging perspective. If a foreign body is suspected, optimal patient management should be done. Prior to the surgery, imaging modalities should be maximally utilized. A careful preoperative evaluation, imaging studies, which are event-specific, a high index of suspicion, and rigorous surgery and postoperative care are the keys in the management of orbital wooden foreign body injuries.

Pattern of childhood ocular morbidity in rural eye hospital, Central Ethiopia

Abstract: This study was aimed to determine the pattern of childhood eye disorders in patients attending outpatient eye department of a rural eye hospital in central Ethiopia. A cross-sectional survey of ocular morbidity among children less than 15 years of age who presented at a rural eye hospital in central Ethiopia between August – October 2012 was conducted. Demographic data, visual acuity, source and type of injury, type of refractive errors and diagnosis were collected and analyzed using SPSS. A p value less than 0.05 was considered statistically significant. A total of 735 children were examined in this study. The age range of the children varied from three months to 15 years of age. The mean (SD) age of the study population was 9.37 (4.95) years. 369 (50.2%) of the patients were females. The majority of cases were observed in older children (11–15 years) accounting for almost half of all the cases. The most common ocular morbidity encountered was conjunctivitis (35%), then ocular trauma (11.8%), refractive error (11.4%) and trachoma (7.6%). Bilateral visual impairment (UCVA < 6/18 in the better eye) was found in 119 children, and the causes were refractive errors (47.1%), keratitis/corneal opacity (16%), amblyopia (14.3%), ocular trauma (11.8%), cataract (6.3%), Glaucoma (2%) and uveitis (2%). The three most common causes of childhood ocular morbidity in this study were conjunctivitis, ocular injuries and refractive errors. These disorders require attention of all the health professionals for proper management or early referral because they can lead to visual impairment and blindness. Health education is necessary for the prevention of childhood eye injuries, as well as early presentation of children to eye care centers for the treatment of eye disorders.

The incidence of serious eye injury in Scotland: a prospective study

Abstract: Purpose: Ocular trauma remains an important cause of visual morbidity worldwide. A previous population-based study in Scotland reported a 1-year cumulative incidence of 8.14 per 100 000 population. The purpose of this study was to identify any change in the incidence and pattern of serious ocular trauma in Scotland. Methods: This study was a 1-year prospective observational study using the British Ophthalmological Surveillance Unit reporting scheme among Scottish ophthalmologists. Serious ocular trauma was defined as requiring hospital admission. Data were collected using two questionnaires for each patient 1 year apart. Results: The response rate from ophthalmologists was 77.1%. There were 102 patients reported with complete data giving an incidence of 1.96 per 100 000 population, four times less than in 1992. In patients younger than 65 years, the age-adjusted incidence ratio (males/females) indicated a ninefold higher risk of trauma in males. In 25 patients (27.2%), the injured eye was blind (final visual acuities (FVA) <6/60), 24 being attributable to the eye injury. Standardised morbidity ratios suggested a threefold decrease in risk of poor visual outcome in 2009 compared with 1992. Conclusions: The incidence of serious ocular trauma has fallen; this study has shown hospital admission for serious eye injury in Scotland has decreased fourfold in 17 years. Young adult males continue to be at highest risk, which needs to be specifically addressed in future health-prevention strategies. This study also observed a reduction in visual loss from serious ocular injuries, although the reasons for this require further exploration.

Exacerbation of blast-induced ocular trauma by an immune response

Abstract: Visual prognosis after an open globe injury is typically worse than after a closed globe injury due, in part, to the immune response that ensues following open globe trauma. There is a need for an animal model of open globe injury in order to investigate mechanisms of vision loss and test potential therapeutics. The left eyes of DBA/2 J mice were exposed to an overpressure airwave blast. This strain lacks a fully functional ocular immune privilege, so even though the blast wave does not rupture the globe, immune infiltrate and neuroinflammation occurs as it would in an open globe injury. For the first month after blast wave exposure, the gross pathology, intraocular pressure, visual function, and retinal integrity of the blast-exposed eyes were monitored. Eyes were collected at three, seven, and 28 days to study the histology of the cornea, retina, and optic nerve, and perform immunohistochemical labeling with markers of cell death, oxidative stress, and inflammation. The overpressure airwave caused anterior injuries including corneal edema, neovascularization, and hyphema. Immune infiltrate was detected throughout the eyes after blast wave exposure. Posterior injuries included occasional retinal detachments and epiretinal membranes, large retinal pigment epithelium vacuoles, regional photoreceptor cell death, and glial reactivity. Optic nerve degeneration was evident at 28 days post-blast wave exposure. The electroretinogram (ERG) showed an early deficit in the a wave that recovered over time. Both visual acuity and the ERG b wave showed an early decrease, then a transient improvement that was followed by further decline at 28 days post-blast wave exposure. Ocular blast injury in the DBA/2 J mouse recapitulates damage that is characteristic of open globe injuries with the advantage of a physically intact globe that prevents complications from infection. The injury was more severe in DBA/2 J mice than in C57Bl/6 J mice, which have an intact ocular immune privilege. Early injury to the outer retina mostly recovers over time. In contrast, inner retinal dysfunction seems to drive later vision loss.

Epidemiology and intermediate-term outcomes of open- and closed-globe injuries in traumatic childhood cataract.

Abstract: PURPOSE: To study epidemiology and intermediate-term outcomes of open- and closed-globe injuries (CGI) in traumatic childhood cataract.METHODS: In this retrospective interventional case series, demographic parameters and history including type of injury of 57 children younger than 16 years with traumatic cataract were recorded; ocular examination included best-corrected visual acuity (BCVA), slit-lamp biomicroscopy, and posterior segment evaluation. Patients underwent cataract surgery with or without intraocular lens (IOL) implantation. Main surgical outcomes at 6 months comprised BCVA, residual refractive spherical error (SE), and postoperative complications, namely visual axis opacification (VAO) and amblyopia.RESULTS: Bow and arrow was the most common causal agent. Open-globe injury (OGI) was 3 times more frequent than CGI. There was a significant visual gain from baseline in both groups after cataract surgery (pCONCLUSIONS: Bow and arrow injury caused the maximum cases of traumatic cataract; cataract extraction resulted in significant visual improvement; and CGI tended to have better prognosis in pediatric traumatic cataracts.

Visual and anatomic outcomes of golf ball-related ocular injuries

Abstract: To investigate the characteristics and prognoses of golf ball-related ocular injuries (GROIs) using standardized terminology, classification, and scoring systems. Twenty-two GROI patients were assessed using the Birmingham Eye Trauma Terminology, Ocular Trauma Classification Group (OTCG) classification, and Ocular Trauma Score. Globe preservation and final visual acuity (FVA) were assessed according to the injury severity categorical designation. Fourteen patients were injured on golf courses and eight on driving ranges. Nine patients (40.9%) had open-globe injuries (five ruptures (22.7%), four penetrating injuries (18.2%)). All rupture cases required enucleation, whereas penetrating injury cases did not (the FVA ranged from 20/100 to no light perception). In open-globe injuries, wearing glasses protected against rupture (P=0.008). Thirteen patients sustained closed-globe injuries that were accompanied by lens subluxation (38.5%), choroidal rupture (30.8%), macular commotio retinae (38.5%), and traumatic optic neuropathy (7.7%). Twelve (54.5%) patients had orbital wall fractures. The mean number of related surgeries required was 1.5±1.7 across all patients. Eyes with GROIs had devastating FVA and globe preservation status, especially those with open-globe injuries. Observing golf rules and improving driving-range facilities are essential for preventing GROIs. Protective eyewear may reduce ocular damage from GROIs, especially globe rupture.

B-scan ultrasonography following open globe repair.

Abstract: Purpose To examine the accuracy andpredictive ability of B-scan ultrasonographyin the post-repair assessment of anopen globe injury.Methods In all, 965 open globe injuriestreated at the Massachusetts Eye and EarInfirmary between 1 January 2000 and 1 June2010 were retrospectively reviewed. A total of427 ultrasound reports on 210 patients wereanalyzed. Ultrasound reports were examinedfor the following characteristics: vitreoushemorrhage, vitreous tag, retinal tear, RD(including subcategories total RD, partialRD, closed funnel RD, open funnel RD, andchronic RD), vitreous traction, vitreousdebris, serous choroidal detachment,hemorrhagic choroidal detachment, kissingchoroidal detachment, dislocated crystallinelens, dislocated intraocular lens (IOL),disrupted crystalline lens, intraocular foreignbody (IOFB), intraocular air, irregularposterior globe contour, disorganizedposterior intraocular contents, posteriorvitreous detachment, choroidal vs retinaldetachment, vitreal membranes, andchoroidal thickening. The main outcomemeasure was visual outcome at finalfollow-up.Results Among 427 B-scan reports, therewere a total of 57 retinal detachments,19 retinal tears, 18 vitreous traction,59 serous choroidal detachments,47 hemorrhagic choroidal detachments, and10 kissing choroidal detachments. Of patientswith multiple studies, 26% developed retinaldetachments or retinal tears on subsequentscans. Ultrasound had 100% positivepredictive value for diagnosing retinaldetachment and IOFB. The diagnoses ofretinal detachment, disorganized posteriorcontents, hemorrhagic choroidal detachment,kissing choroidal detachment, and irregularposterior contour were associated with worsevisual acuity at final follow-up. Disorganizedposterior contents correlated with particularlypoor outcomes.Conclusions B-scan ultrasonography is aproven, cost-effective imaging modality inthe management of an open globe injury.This tool can offer both diagnostic andprognostic information, useful for bothsurgical planning and further medicalmanagement.Eye advance online publication, 10 January 2014;doi:10.1038/eye.2013.289Keywords: ultrasound; ultrasonography; openglobe; ocular traumaIntroductionOne of the most important roles for B-scanultrasonography remains diagnosis and follow-upof ocular trauma. Ultrasonography can functionto diagnose intraocular pathology immediatelyfollowing ocular trauma when no additionalimaging is possible,

Determination of visual prognosis in children with open globe injuries

Abstract: AIMS: To determine the predictive factors of visual outcomes in children with open globe injury and to give guidance to reduce the incidence of open globe injury.METHODS: One hundred and forty eyes of 137 consecutive open globe injury patients, who were treated at the Eye Center of Second Bethune Hospital affiliated with Jilin University between August 2005 and August 2012, were retrospectively analyzed. Data recorded included demographic characteristics, causes of injury, location and extent of injury, presenting visual acuity, detailed ocular anterior and posterior segment evaluations, details of primary and subsequent surgeries, and postoperative complications and outcomes. The follow-up data included the most recent best-corrected visual acuity, complications, and the duration of follow-up.RESULTS: Of the 137 patients, there were 116 (84.7%) boys and 21 (15.3%) girls. Their ages ranged between 3 and 17 years old (mean=11.57±4.19 years old). Sixty (43.8%) children had a right eye injury, whereas 74 (54.0%) had a left eye injury. Only three (2.2%) children suffered bilateral eye injury. Living utensils, industrial tools, and fireworks contributed to the most common causes of open globe injury. Eighty-one (59.1%) had sharp force injuries, 23 (16.8%) had blunt injuries, and 33 (24.1%) had missile injuries.CONCLUSIONS: Unfavorable visual outcomes were related to a younger age at presentation, poor presenting visual acuity, injuries caused by blunt or missile objects, posterior wound location, hyphema, vitreous hemorrhage, and surgical intervention of pars plana vitrectomy.

Characteristics and outcomes of pediatric open globe injury

Abstract: To describe the epidemiology, mechanism of injury, and final visual and anatomical outcomes of pediatric patients with open globe injury. The medical records of patients aged ≤16 years diagnosed with open globe injury between January 2006 and December 2010 were retrospectively reviewed. Forty-nine pediatric patients were diagnosed with open globe injury during the study period. Forty-one of the 49 patients (83.7 %) were male. The mean age of the patients was 9.3 ± 4.6 years, with 49 % of the injuries occurring in patients between the ages of 11 and 16 years. Ocular penetration was the most common type of injury (63.3 %), occurring most frequently in the cornea (63.3 %). Wooden objects were the most common cause of injury. Following surgical intervention, 40.8 % of the patients obtained a final visual acuity (VA) of ≥6/60. Pars plana vitrectomy was performed in 51 % of cases, with only 36 % of these patients having a final VA of ≥6/60. The presence of retinal detachment was the only statistically significant factor (odds ratio 0.05, p < 0.001) that affected VA improvement of more than one line. Corneal penetration was frequently observed in pediatric patients with ocular trauma. Pediatric patients with a retinal detachment were significantly more likely to have a poor final visual outcome than open globe patients whose retina remained attached. Despite prompt surgical intervention, useful vision was preserved in less than half of the patients requiring pars plana vitrectomy.

23-gauge vitrectomy with intraocular foreign body removal via the limbus: An alternative approach for select cases

Abstract: 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.

Intraocular Penetration of Systemic Antibiotics in Eyes with Penetrating Ocular Injury

Abstract: Purpose: To determine whether penetrating scleral or corneal injury can enhance intraocular penetration of systemic moxifloxacin, vancomycin, and ceftazidime. Methods: Thirty rabbits were divided into 3 groups for each antibiotic and then further subdivided to receive either scleral or corneal injury to the right eye. The left eye served as a control. Intravenous antibiotics were given following injury, and eyes were subsequently enucleated. Vitreous antibiotic concentration was determined by high-performance liquid chromatography analysis. Plasma concentration was measured for comparison. Results: Intravitreal moxifloxacin concentration was unchanged by injury. Minimum inhibitory concentration (MIC90) was achieved in the vitreous against the most common gram-positive endophthalmitis-causing organisms. Intravitreal vancomycin levels were not enhanced by injury and did not reach the MIC90 for gram-positive organisms commonly causing intraocular infection. Intravitreal ceftazidime was increased in ...

Metallic corneal foreign bodies: an occupational health hazard

Abstract: Purpose: To analyze the risk factors, outcomes, demographic characteristics, and attitudes of workers with metallic corneal foreign body (FB) injury. Methods: One hundred consecutive patients who presented with a metallic corneal FB to the eye clinic at Diyarbakir Training and Research Hospital were evaluated. The patients completed a questionnaire and were examined to determine features of the injury. Results: All patients were male. The mean age was 32.46 ± 1.03 years. Fiftyfive percent of the patients were unregistered workers, 59% were working in the metal industry sector, and 65% injuries resulted from metal cutting. Protective goggles were available in the workplace of 64% patients. However, 57% patients were not wearing goggles when the accident occurred, and 43% were injured despite goggle use. Most patients (52%) attempted to remove FBs by themselves. FBs were located in the central zone of the cornea in 16% patients. Rust marks remained after FB removal in 26% patients. Corneal scars from previous FB injuries were present in 58% patients. Only 8% workplaces provided compensation for physician visits for occupation related illnesses. Conclusions: Workplaces with a high risk for eye injuries should increase their protective measures, and educational programs should be implemented for both workers and occupational physicians. The government should enforce laws regarding unregistered workers in a better manner.

Fingernail-induced corneal abrasions: case series from an ophthalmology emergency department.

Abstract: Purpose Fingernail-induced corneal abrasions are one of the most common eye injuries that present to the emergency department, and yet there is little literature available to offer guidelines for management. We analyzed the treatment used in cases of fingernail-induced corneal abrasions that presented to the Massachusetts Eye and Ear Infirmary Emergency Department and studied its relationship to the development of complications such as recurrent erosion syndrome and infection. Methods We performed a retrospective review of 99 patients who presented to the Massachusetts Eye and Ear Infirmary Emergency Department with fingernail-induced corneal abrasions between January 1, 2009 and December 31, 2009. We followed the patients for 12 months and documented demographics, nature of the injury, treatment, and complications. Results The average age was 29.4 (range, 2-89) years. Forty-four percent (n = 44) were female and 56% (n = 55) were male. Of the 99 subjects, 39 had a full 12 month follow-up, and 7 developed a complication from the injury. Compared with the 32 subjects without complications, there was no difference in age or gender. However, there was a significant difference in that adults scratched by another adult were more highly represented in the group with complications (43%, n = 3/7 vs. 3%, n = 1/32; P = 0.0017). There was no significant difference in outcome by treatment used. Conclusions This is the largest fingernail-induced corneal abrasion study completed to date. Patients are at risk of developing complications, but there is scant evidenced-based literature available for treating this common injury. Prospective trials should be performed to better optimize and standardize treatments.

Nail gun-induced open-globe injuries: A 10-year retrospective review

Abstract: PURPOSE:: To describe the characteristics of nail gun-related open-globe injuries. METHODS:: Retrospective series of all patients presenting with open globes secondary to nail gun injury from 2000 to 2010. Data were collected on demographics, setting of accident, presenting clinical examination findings, visual acuity, management, surgical procedures needed, and long-term outcomes. RESULTS:: Forty-two patients (43 eyes; mean age, 31.6 years; 100% male; 79% Hispanic) suffered open-globe injury from nail gun accidents. Thirty-seven eyes (86%) sustained injury at work. One of 15 (6.7%) patients, on whom data were available, wore protective eyewear during the incident. Entrance wounds were classified into Zone I (n = 24 [56%]), Zone II (n = 12 [28%]), and Zone III (n = 7 [16%]). Six eyes (14%) had retained intraocular foreign bodies. Mean presenting logarithm of the minimum angle of resolution visual acuity was 1.64 ± 0.83, whereas mean final logarithm of the minimum angle of resolution visual acuity was 1.01 ± 0.96 (P = 0.004). Two eyes (4.7%) had no light perception vision at final examination. Seventeen (40%) patients developed a traumatic cataract, and 2 (4.7%) had dislocated lens fragments. Most common findings on presentation included vitreous hemorrhage (n = 30 [70%]) and hyphema (n = 28 [64%]). Two eyes (4.7%) had a retinal detachment at presentation, and 10 (23%) developed a retinal detachment during follow-up visits. Anatomical success was observed in 11 eyes (92%) with a retinal detachment. Three eyes (7.0%) became phthisical or prephthisical, and 1 was enucleated for severe pain. No eyes developed endophthalmitis or sympathetic ophthalmia. CONCLUSION:: This is the largest compilation of nail gun-related open-globe injury reported to date. Posterior segment complications, noted in the majority of cases, likely contributed to the overall guarded visual outcomes. Preventative measures for eye protection should be strictly followed while using nail guns. Language: en

Motor vehicle crash-associated eye injuries presenting to U.S. emergency departments.

Abstract: Introduction: Motor vehicle crashes (MVCs) are a leading cause of injury in the United States (U.S.). Detailed knowledge of MVC eye injuries presenting to U.S. emergency departments (ED) will aid clinicians in diagnosis and management. The objective of the study was to describe the incidence, risk factors, and characteristics of non-fatal motor vehicle crash-associated eye injuries presenting to U.S. EDs from 2001 to 2008. Methods: Retrospective cross-sectional study using the National Electronic Injury Surveillance System All Injury Program (NEISS-AIP) from 2001 to 2008 to assess the risk of presenting to an ED with a MVC-associated eye injury in relation to specific occupant characteristics, including age, gender, race/ethnicity, disposition, and occupant (driver/passenger) status. Results: From 2001 to 2008, an estimated 75,028 MVC-associated eye injuries presented to U.S. EDs. The annual rate of ED-treated eye injuries resulting from MVCs declined during this study period. Males accounted for 59.6% of eye injuries (95% confidence interval [CI] 56.2%-63.0%). Rates of eye injury were highest among 15-19 year olds (5.8/10,000 people; CI 4.3-6.0/10,000) and among African Americans (4.5/10,000 people; CI 2.0-7.1/10,000). Drivers of motor vehicles accounted for 62.2% (CI 58.3%-66.1%) of ED-treated MVC eye injuries when occupant status was known. Contusion/Abrasion was the most common diagnosis (61.5%; CI 56.5%-66.4%). Among licensed U.S. drivers, 16-24 year olds had the highest risk (3.7/10,000 licensed drivers; CI 2.6-4.8/10,000). Conclusion: This study reports a decline in the annual incidence of ED-treated MVC-associated eye injuries. The risk of MVC eye injury is greatest among males, 15 to 19 year olds and African Americans. [West J Emerg Med. 2014;15(6):-0]

Clinical features and outcomes of vitrectomy in pediatric ocular injuries-eye injury vitrectomy study.

Abstract: 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.

Paintball-related ocular trauma: Paintball or Painball?

Abstract: BACKGROUND The aim of this study is to describe the type and severity of paintball-related ocular trauma and to determine the necessary precautions to minimize the risk of ocular injury regardless of whether adequate eye protection was used. METHODS A retrospective chart review identified patients treated for paintball-related ocular trauma at the Ataturk University Medical Hospital from June 2010 through March 2013. A descriptive analysis of data was performed. RESULTS Ten patients with paintball-related ocular trauma were identified. At the time of their first examination, 7 of these patients had visual acuity (VA) of 20/200 or worse. One patient had a final VA of no light perception and 4 patients had a final VA of 20/200 or worse. Hyphema was noted in 7 patients, traumatic cataract in 2, iridodialysis in 2, retinal detachment in 3, and secondary glaucoma in 1. Six patients required surgery. Although all victims have used eye protection during the game, all patients were injured after they thought the game was over and had taken off their helmets or eye-protective devices. CONCLUSIONS Paintball-related accidents result in serious ocular trauma and most of the patients require surgery. These injuries result in severe loss of VA in some patients. Uninterrupted use of proper eye protection whenever a player is in the game field, even after they believe the game has ended, may reduce the incidence of severe ocular trauma in paintball players.

The use of rigid eye shields (Fox shields) at the point of injury for ocular trauma in Afghanistan.

Abstract: BACKGROUND: Unlike hemorrhagic injuries in which direct pressure is indicated, any pressure placed on the eye after penetrating trauma can significantly worsen the injury by expulsing intraocular contents. The accepted first response measure for obvious or suspected penetrating ocular injury is placement of a rigid shield that vaults the eye so as to prevent accidental iatrogenic aggravation during transport to the ophthalmologist. Patching and placing intervening gauze between the shield and the eye are both contraindicated. Anecdotally, compliance with these recommendations is poor in the military and civilian communities alike; however, published studies documenting compliance are uniformly lacking. This study was undertaken to provide such an evaluation. METHODS: In this retrospective observational study, the Department of Defense Trauma Registry was reviewed to identify eye injuries in Afghanistan from 2010 to 2012 and to examine compliance with eye shield recommendations. One hundred fifty-seven records of eye casualties were identified and categorized according to diagnostic codes, noting use of a shield. A subset of 30 records was further analyzed for compliance with other core treatment measures specified by the operant Clinical Practice Guideline. Because comparative studies do not exist, simple statistical analysis was performed. RESULTS: Overall, 39% of eye injuries received a shield at the point of injury (61% failure), ranging from 0% to 50% between diagnostic subgroups. Subset analysis revealed that only 4.2% of injuries were successfully mitigated at the point of injury (95.8% failure). CONCLUSION: In one of the few studies documenting the use of eye shields after ocular trauma, anecdotal reports of poor, inadequate, or incorrect compliance with basic recommendations were substantiated. Several factors may account for these findings. Corrective efforts should include enhanced educational emphasis and increased shield availability. LEVEL OF EVIDENCE: Epidemiologic study, level IV.

Epidemiology of traumatic lenticular subluxation in India.

Abstract: To study the epidemiological and clinical profile of patients with traumatic subluxated lenses at a tertiary care center in India. Ours was a non-comparative descriptive case series. Evaluation of 71 eyes of 71 consecutive patients presenting to the lens clinic over a period of 2 years with traumatic lenticular subluxation was done. Demographic and clinical profile of patients was acquired, followed by a biomicroscopic examination of the cornea, anterior chamber, iris, lens, angles, zonules, anterior vitreous and fundus. Most of the patients were adolescents and belonged to lower socioeconomic status. The mean time lag before presenting was 33.6 months (range 5 days to 40 years) and mean visual acuity in the affected eyes was 1.67 + 0.56 logMAR. Blunt trauma (63/71) was nine times more common than penetrating trauma in the etiology of manifest subluxation. Injury while playing accounted for the highest rate of injury; sports-related injury with a gulli danda or a cricket bat and ball were the most common mode of blunt trauma while bow and arrow injury was the commonest cause of injury in the penetrating trauma subgroup. Cataract was the most frequent ocular association (53.5 %). All eyes had broken zonules and most presented with inferior subluxation (46 %). Traumatic lenticular subluxation, a unilateral cause of zonulolysis usually occurs while playing with a gulli danda, bow and arrow, or cricket bat and ball in Northern India. It is a major cause of severe visual loss and a modification in risk factors is mandatory to decrease ocular morbidity from trauma.

A new classification for epidemiological study of mechanical eye injuries

Abstract: OBJECTIVE: Considering the difficulty in classifying some cases with eye trauma by Birmingham Eye Trauma Terminology (BETT) in our epidemiological study, we introduce a new classification for epidemiological study of mechanical eye injuries based on BETT. METHODS: A retrospective investigation was carried out in 31 hospitals from January 2005 to December 2010. All medical records of inpatients with eye injuries were reviewed. A total of 10 718 patients (11 227 eyes) were diagnosed as mechanical eye injuries. All mechanical eye injuries were tried to be classified using BETT. While some eye injuries were difficult to categorize. We recorded the injury type and case number. A new classification based on BETT was also used for the same project. RESULTS: Of 10 718 patients (11 227 eyes) with mechanical eye injuries, the following cases cannot be classified by BETT: 1 488 patients (1 559 eyes) with merely orbital or ocular adnexa injury, 1 961 (2 054) globe injuries associated with orbital or ocular adnexa injury, 271 (284) ocular surface foreign body (OSFB) or ocular wall foreign body (OWFB), 77 (89) contusion, 9 (11) lamellar laceration associated with OSFB or OWFB, 29 (30) rupture associated with OSFB, OWFB or intraocular foreign body and 60 (62) lace- ration associated with OSFB or OWFB. While according to our new classification, all eye injuries can be categorized without any difficulty. CONCLUSION: Difficulty in classifying some eye injuries in epidemiological study by BETT brings some trouble to our study, which can be solved by our new eye injury classification to some extent. It is hoped that other ophthalmologists present better ones to make the classification more perfect. Language: en

Survivors of Self-inflicted Gunshot Wounds to the Head: Characterization of Ocular Injuries and Health Care Costs

Abstract: Importance Suicides and attempted suicides are major public health issues in the United States and around the world. Self-inflicted gunshot wounds (SIGSWs) are a common method of attempting suicide, the head being the most commonly injured body region; however, the literature lacks an overview of the orbital and ocular injuries as well as outcomes associated with SIGSWs. Objectives To characterize the ocular and orbital injuries and outcomes of patients presenting with SIGSWs and to examine the cost associated with these injuries. Design, Setting, and Participants Retrospective medical record review was performed of all patients who presented to the University of Iowa Hospitals and Clinics between 2003 to 2013 with the admitting diagnosis of self-inflicted injuries via firearms. Patients with no periorbital or ocular injuries and/or those who did not survive for at least 2 months following the incident were excluded. Main Outcomes and Measures Ocular injuries and outcomes and health care costs and reimbursements, which were generated by a financial report obtained from the hospital finance department that included data from both the hospital billing and cost accounting systems. Results All patients in this study (n = 18) were men with a mean age of 47.2 years. Eight patients (44.4%) displayed submental missile entry points, 7 (38.9%) displayed intraoral entry points, and 3 (16.7%) displayed pericranial entry points. Patients with pericranial entries sustained more severe ocular injuries and had poorer ocular outcomes. Seven patients (38.9%) were found at final follow-up to have visual acuity of 20/40 or better in each eye and all showed missile trajectories in the sagittal plane. The mean cost of treatment of these patients totaled $117 338 while the mean reimbursement amount was $124 388. Conclusions and Relevance Data regarding ocular injuries and outcomes may assist ophthalmologists in the treatment of patients with SIGSWs in the future. Many patients had extremely functional vision at final follow-ups, which highlights the importance of specialists conducting examinations and reconstructive procedures promptly, carefully, and thoroughly. Cost and reimbursement data suggest that while these cases place a large financial burden on society, they may not burden hospital systems in the same way.

Ocular injuries in the people's uprising of April 2006 in Kathmandu, Nepal

Abstract: Introduction: In April 2006, the people of Nepal organised mass demonstrations demanding the restoration of democracy in the country. The ocular injuries that resulted during the riots that ensued, their pattern and the visual outcome of the injured have not yet been reported. Objective: To study the demographic profile, type, severity and the visual outcome of ocular injuries that occurred during the 2006 people’s uprising in Nepal. Subjects and methods: This was a retrospective interventional series of cases involving 29 subjects. The main outcome measures were demography, laterality of injury, type of injury and the visual status before and after the trauma. Results: The age of the victims ranged from 14 to 32 years. Among the victims with eye injuries, 27 (93.1 %) were males, who were unemployed youth, students and construction workers. The left eye was injured more frequently than the right. Non-lethal bullets and explosive tear gas were the commonest agents of the major ocular injuries. The main types of injuries requiring hospitalization were closed globe injuries in eight victims and open globe in six. Surgical intervention was required in 57.2 % (n = 29) of the cases. The visual outcome was poor in cases of open globe injury with posterior segment involvement. Conclusion: Non-lethal bullets and explosive tear gases can cause significant visual impairment. Severe open globe injury with a retained intra-ocular foreign body is associated with significant visual loss. DOI: http://dx.doi.org/10.3126/nepjoph.v6i1.10775 Nepal J Ophthalmol 2014; 6 (2): 71-79

Bilateral maculopathy following electrical burn: case report.

Abstract: CONTEXT: Electrical burns are an important etiology in dealing with patients suffering from burns. In situations of extensive deep lesions of multiple organs and systems affecting young and economically active people, there is a need for expensive multidisciplinary treatment, with a high socioeconomic cost for the community. Among the permanent injuries that explain this high cost, eye injuries stand out, since they are widely disabling. Although rare, lesions of the posterior segment of the eye are associated with higher incidence of major sequelae, and thus deserve special attention for dissemination and discussion of the few cases observed.CASE REPORT: The authors report the case of a patient who suffered high-voltage electrical burns and presented bilateral maculopathy, which evolved with a need for a surgical approach to repair retinal detachment and permanent low visual acuity.CONCLUSION: This report highlights the rarity of the etiology of maculopathy and the need for campaigns for prevention not only of burns in general, but also especially of electrical burns.

Management of anterior segment trauma.

Abstract: Ophthalmologic emergencies have the potential to lead to severe morbidity and loss of vision. The ability to recognize and efficiently relay pertinent findings to an ophthalmologist is critical to preventing life-changing damage to the eye. Basic understanding of ocular anatomy, physiology, and pathology will facilitate a successful discussion between an ophthalmologist and the referring physician. As with other specialties, a detailed HPI should be attained that includes basic information such as onset, duration, intensity, and medication use. A useful review of systems includes questions regarding flashing lights, floaters, vision loss, and pain. Additionally, performing an ocular examination that checks visual acuity, intraocular pressure, and pupils will be advantageous to you, the ophthalmologist, and the patient. Anterior segment trauma involves injury to the part of the eye that is visible to the naked eye. Briefly, with the patient's lids open, one should be able to see the conjunctiva, sclera, cornea, iris, and pupil. Identification of these structures is critical and expected of physicians at any level. The variety of anterior segment trauma one may encounter is vast, thus, this article will focus on the presentation, diagnosis, and treatment of chemical burns, corneal abrasions, hyphemas, and traumatic iritis.
