Visual Outcome after Fireworks Injuries

Firework related ocular injuries in Eastern India - A clinico-epidemiological analysis

Purpose

:Ocular trauma is one of the major preventable causes of ocular morbidity and blindness in children and young adults. Firework injuries account for 20% of ocular trauma. The purpose of this study was to describe the clinical profile and assess the severity of the ocular injuries sustained from fireworks in Eastern India mainly during the festive season.

Methods

:This was a retrospective, hospital-based case study of patients with ocular injuries sustained from fireworks during the year 2017-2020. The study was conducted at a tertiary care hospital in Eastern India. Demographic details, type of injury, duration of injury, visual status, diagnostic tests, and management were recorded.

Results

Sixty-five patients were reported to suffer from firework-related ocular injuries. The majority of cases were male (51/78.5%). The mean age was 21.78 ± 16.82 years (range: 0-90 years). Children and young adult males were mostly affected (n = 40, 61.5%). Most common offending agent was the bottle rockets (n = 23, 35.4%), followed by bomb and crackers in (n = 18, 27.7%). Majority of the injuries occurred at home environment (n = 37, 56.9%), followed by street (n = 15, 23.1%). About (n = 39, 60%) of the injuries occurred among bystanders. About 40 cases (61.5%) hailed from rural areas. The majority of the cases (n = 46, 70.8%) suffered from closed globe injuries and surgical intervention was required in (n = 40, 61.5%) of the cases. The mean length of hospital stay of fewer than 5 days was required in (n = 42, 64.6%). The final visual acuity of 6/18 or better was achieved in 41 cases (63.1%).

Conclusion

:Ocular injuries from fireworks remain a public health problem. Awareness among the masses, preventive measures, and strict implementation of government legislation may help in bringing down the incidence of firework-related ocular morbidity and blindness.

Profile and Management Outcomes of Fireworks-Related Eye Injuries in Saudi Arabia: A 16-Year Retrospective Study

BACKGROUND

Fireworks are a culturally significant part of celebrations in many parts of the world but can lead to blinding injuries.

OBJECTIVE

To decipher the profile and management outcomes of fireworks-related eye injuries at a tertiary eye hospital in central Saudi Arabia.

METHODS

This was a retrospective review of cases with fireworks-related eye injuries managed at our institution between 2003 and 2019. Demographic information, clinical features at presentation, mode of management, and visual outcome were evaluated at the last follow-up.

RESULTS

A total of 155 eyes of 150 patients with a median age of 10 years [127 male (84.7%) and 69 (46%) right eyes, 76 (50.7%) left eyes, and 5 patients with bilateral injury] were enrolled for the study. Among the injured individuals, 59 (39.3%) were bystanders and 91 (60.7%) had ignited the fireworks. The fireworks included bangers (53; 35.3%), rockets in bottle (42; 28%), firecrackers (41; 27.3%). Closed globe injury (CGI) was the most common type of eye injury (100; 64.5% eyes) while Open globe injury (OGI) was noted in (55; 35.5% eyes). Management used for treatment included penetrating injury repair (55; 35.5%), lens removal/lens implant (51; 32.9%). Corrected distance visual acuity obtained after 6 months was 20/20 to 20/60 (74; 47.7%), 20/70 to 20/200 in (31; 20%), <20/200 to 20/400 in (9; 5.8%) and <20/400 in (41; 26.5%) eyes. Treatment was able to restore vision and salvage blindness in 50 (32.3%) eyes.

CONCLUSION

Mainly males were found to suffer from fireworks-related eye injuries and the main fireworks responsible for them were bangers. Visual disability remained in one-third of the treated patients.

Mechanism and prognostic indicators for explosion-related eye trauma: eye injury vitrectomy study

PURPOSE

To explore the clinical features, surgical interventions and prognosis of injured eyes following explosion and to develop the risk factors for poor prognosis.

METHODS

A nested case-control study. To the date of 31 December 2018, 99 explosion-related eye globes were selected from the Eye Injury Vitrectomy Study database, which is a multicenter prospective cohort study and began in 1990s. All cases selected underwent vitreoretinal surgery or enucleation and were followed up for at least 6 months. Clinically meaningful preoperative variables and outcomes were used to develop logistic regression models.

RESULTS

The unfavourable outcomes were defined as silicone oil-filled eyes, phthisis bulbi, enucleation and anatomically restored eyes whose final BCVA is worse than initial vision after 6 months of follow-up. The proportion of unfavourable outcomes was 92.0%, 60.9% and 66.7% in large festive fireworks, detonator and beer bottle groups respective. The anatomic and visual outcome of injured eyes with combined injury of blast wave and projectile were worse than that of ruptured eyes (Fisher's exact = 0.041). The extrusion of iris/lens (OR = 3.20, p = 0.015), PVR-C (OR = 6.08, p = 0.036) and choroid damage (OR = 5.84, p = 0.025) is independent risk factors of unfavourable prognosis for explosion-related eye trauma.

CONCLUSION

The extrusion of iris/lens, PVR-C and choroid damage is the independent risk factors for unfavourable outcomes in explosion-related eye trauma. There is a unique injury mechanism in explosion-related eye trauma.

SUMMARY STATEMENT

Through the nested case-control study, the extrusion of iris/lens, PVR-C, and choroid damage are the independent risk factors for unfavorable outcomes in explosion-related eye trauma. The mechanism of open globe mixture and close globe mixture in explosion-related eye trauma need more cases and participating units to explore together in the future.

Appraising the spectrum of firework trauma and the related laws during Diwali in North India

PURPOSE

To evaluate the epidemiological characteristics and outcomes of ocular injuries resulting from the use of firecrackers during the Diwali festival in all age groups.

MATERIALS AND METHODS

A single-center, retrospective, hospital-based case series presenting with ocular trauma consequent to fireworks usage in a tertiary eye care center in North India during the 5 days of Diwali festival from 2011 to 2015 was conducted.

RESULTS

A total of 53 eyes of 45 patients were included in the study, out of which the vast majority (39/87%) were males. The mean age was 20.55 years. Almost an equal number of bystanders (25/55.5%) were affected as compared to people handling the fireworks (20/44.44%). Five (9.43%) eyes had open-globe injury, whereas 48 (90.56%) eyes had closed-globe injury. Eighteen (33.96%) eyes underwent surgical intervention. Thirty-three (62.26%) eyes had final vision >20/200 with eight (15.09%) eyes being vision <3/60 in the affected eye.

CONCLUSION

Firework-related ocular trauma can lead to serious visual impairment. Mandatory legislative laws pertaining to the manufacture, sale, and use of fireworks and creating public awareness can reduce the incidence of this preventable cause of blindness in the society. Initiating new policies for retailers involved in sale of these firecrackers can also bring in decrease of such morbidities.

Ocular injuries from fireworks: the 11-year experience of a US level I trauma center

PurposeCharacterize ocular trauma and visual outcomes from firework injuries at a level I trauma center.MethodsRetrospective review of all firework injuries at Harborview Medical Center between 2003 and 2013.ResultsThree hundred and twenty-seven patients sustained firework injuries, of which 100 (31%) sustained ocular injuries. The average age of all patients who sustained fireworks injuries was 24.2 years, 89% were male and 54% of injuries occurred within 48 h of 4 July. Ocular injuries were most commonly caused by mortars (24%) and rockets (22%). Rockets were associated with four times the frequency of ocular injuries as compared with non-ocular injuries (P<0.001). Spectators were more likely to sustain ocular injuries than non-ocular injuries (P=0.001). The most common injuries sustained were corneal abrasions (67%), hyphemas (42%), eyelid injuries (39%), and ruptured globes (17%). Twenty-eight percent of patients with ocular injuries required surgical intervention. Ruptured globes occurred in 17% of patients, with the majority being complex corneoscleral lacerations. Fifty-eight percent of patients who sustained ruptured globes were left with no light perception in the affected eye. Average follow-up was 188 days. Average visual acuity significantly improved from logMAR 1.8±1.6 at presentation to logMAR 1.3±1.8 at last follow-up.ConclusionsFirework-related ocular trauma frequently results in vision-threatening pathology. Prompt referral to and treatment by ophthalmologists is critical. This study documents the dangers inherent in the personal use of fireworks and provides data that may help guide public policy to decrease the frequency of these devastating injuries.

Injuries due to fireworks use: A surveillance data analysis in Colombia, 2008-2013

PURPOSE

To describe the injuries due to fireworks use in Colombia during the period 2008-2013 and to identify factors associated with hospitalization and death due to this cause.

METHODS

A descriptive study from surveillance data was carried out. Incidence rates and relative risks were calculated. The incidence rate trend was modeled with a joint point regression model. Multivariate logistical models were implemented to identify the associated factors with hospitalization and mortality due to firework injuries.

RESULTS

A total of 6585 people were reported to be injured by fireworks during the 2008-2013 period. An upward trend in the incidence rate during this period was observed, with an annual percentage of change of 28% (95% CI 27.7-28.3) during 2008-2011 and 3.5% (95% CI 3.0-3.9) during 2011-2013. The factors associated with hospitalization were injury occurrence at the workplace (odds ratio (OR) 2.62, 95% CI 1.97-3.47), storage (OR 2.40, 95% CI 1.54-3.73), transport (OR 1.63, 95% CI 1.20-2.21), multiple trauma (OR 1.49, 95% CI 1.31-1.70), and injury occurrence at home (OR 1.26, 95% CI 1.07-1.50). The factors associated with mortality were storage (OR 19.52, 95% CI 4.62-82.44), transport (OR 13.37, 95% CI 3.29-54.3), injury occurrence at the workplace (OR 4.88, 95% CI 1.69-14.13), and ethnicity (OR 3.37, 95% CI 1.12-10.12).

CONCLUSION

These results provided information for revising the public policies and intersectorial interventions to reduce the avoidable burden due to firework injuries at all times and not just during the high injury occurrence season.

Crash and Burn: Ocular Injuries due to Fireworks

PURPOSE

To identify the patterns of ocular injury and to determine ocular morbidity resulting from the use of firecrackers.

METHODS

A prospective observational study of all patients presenting with ocular trauma consequent to fireworks usage in a tertiary eye care center in South India over a one-month period around the autumn festival of Diwali. We also reviewed the published literature from around the world reporting ocular injuries due to firecrackers.

RESULT

49 patients were included in the study, out of which the vast majority (40/81%) were males. The mean age was 17 years. Almost an equal number of bystanders (24/48.9%) was affected as compared to people handling the fireworks (25/51%). 13 (26.53%) patients had open-globe injury whereas 33 (67.34%) patients had closed-globe injury. Twenty-two (44.8%) patients underwent surgical intervention. Eighteen (36.7%) patients had final vision less then 20/40 (range = 20/50 to No Perception of Light) with eight patients having no perception of light in the affected eye.

CONCLUSION

Unregulated use of firecrackers can lead to significant ocular morbidity, mainly involving children, young males, and even innocent bystanders. A combination of public awareness and appropriate legislative laws should be formulated regarding the use of fireworks to decrease the load of needless blindness on society.

Attenuation of smoke induced neuronal and physiological changes by bacoside rich extract in Wistar rats via down regulation of HO-1 and iNOS

Bacopa monniera is well known herbal medicine for its neuropharmacological effects. It alleviates variety of disorders including neuronal and physiological changes. Crackers smoke is a potent risk factor that leads to free radical mediated oxidative stress in vivo. The aim of the current study is to evaluate the protective efficacy of B. monniera extract (BME) against crackers smoke induced neuronal and physiological changes via modulating inducible nitric oxide synthase (iNOS) and hemeoxygenase-1 (HO-1) expression in rats. Rats were exposed to smoke for 1h for a period of 3 weeks and consecutively treated with BME at three different dosages (i.e., 10, 20 and 40 mg/kg b.wt.). Our results elucidate that BME treatment ameliorates histopathalogical changes, reactive oxygen species levels, lipid peroxidation, acetylcholine esterase activity and brain neurotransmitter levels to normal. BME supplementation efficiently inhibited HO-1 expression and nitric oxide generation by down-regulating iNOS expression. Smoke induced depletion of antioxidant enzyme status, monoamine oxidase activity was also replenished by BME supplementation. Thus the present study indicates that BME ameliorates various impairments associated with neuronal and physiological changes in rats exposed to crackers smoke by its potent neuromodulatory, antioxidant and adaptogenic propensity.

Work-related open-globe injuries: demographics and clinical characteristics

PURPOSE

To describe the demographics and clinical characteristics of work-related open-globe injuries (OGIs) at a level I trauma center over a 10-year period.

METHODS

Retrospective series.

RESULTS

A total of 183 eyes with work-related OGIs were identified. The majority of injuries occurred in men (96.7%). The anatomic site of the wound was zone 1 in 107 eyes (72.3%). The most common cause was nail gun use (47.0%). The types of OGI included 32 ruptures (17.5%), 112 penetrating injuries (61.2%), 38 intraocular foreign bodies (IOFB) (20.8%), and 1 mixed rupture/IOFB injury (0.5%). Presenting visual acuity (VA) was worse than 20/200 in 112 eyes (65.9%) and no light perception (NLP) in 10 eyes (5.8%). Final VA worse than 20/200 occurred in 64 eyes (37.2%); 11 eyes underwent enucleation. In comparison to non-work-related OGIs (420 eyes), we found significant differences in types and zones of injury, initial and final mean VA, enucleation rate, incidence of cataracts, hyphema, retinal detachment, hemorrhagic choroidals, and afferent pupillary defect (APD). Using multivariate analysis, significant prognostic factors for a final VA of NLP were zone 3 injury, rupture injury, and initial VA of NLP. Risk factors for enucleation included zone 3 injury, APD, and endophthalmitis.

CONCLUSIONS

Work-related injuries were noted to have a much higher incidence of IOFBs and cataracts compared to non-work-related OGIs. Zone 3 injuries, rupture injuries, and a presenting VA of NLP were found to be significant predictors for a final VA of NLP. Zone 3 injury, APD, and endophthalmitis were found to be significant predictors for enucleation.

Effect of penetrating and blunt ocular trauma on the outcome of traumatic cataract in children in northern India

BACKGROUND

We studied the demographic profile and outcome of traumatic cataract after penetrating and blunt ocular trauma in children in northern India.

METHODS

We reviewed the medical records of children with penetrating and blunt ocular trauma associated with traumatic cataract who underwent cataract surgery with posterior chamber intraocular lens implantation and having more than 1 year follow up. We evaluated the demographic characteristics and visual outcome in the affected eye.

RESULTS

Of the 100 children (100 eyes), 65 were penetrating trauma and 35 were blunt trauma. The common modes of injury in the penetrating group were wooden splinters in 30.8% and bow and arrow in 15.4%. Fire crackers and trauma during play with ball were seen in 34% and 11.4% of blunt eye trauma, respectively. The age ranged from 1 to 14 years (mean, 7.8 years) in the penetrating trauma and 2 to 15 years (mean, 8.3 years) in the blunt trauma group. The best corrected visual acuity of 20/40 or better was achieved in 57.6% eyes in penetrating group compared with 71.4% in the blunt trauma group. Visually significant posterior capsular opacification developed in 32.3% eyes in penetrating group and 28.6% eyes in blunt trauma group. Glaucoma was diagnosed in 4.6% eyes in penetrating group and 8.6% in blunt trauma group.

CONCLUSION

Eye injuries with traumatic cataract are associated with significant visual impairment. There were more children with penetrating eye injuries as compared with blunt trauma. Cataract surgery with intraocular lens implantation is a preferred method for visual rehabilitation in these children.

LEVEL OF EVIDENCE

Epidemiologic study, level IV.

Prognostic factors and visual outcome for fireworks-related burns during spring festival in South China

The aim of this study was to evaluate the clinical features and the visual results of fireworks-related ocular burn injuries and to determine the prognostic factors. The authors conducted a prospective observational study of 53 eyes of 46 consecutive patients with fireworks-related ocular injury who visited Zhongshan Ophthalmic Center during the Spring Festival in Southern China. Eyes were graded using an ocular trauma classification system, which included age of the patient. Patients were followed up for a minimum of 5 months. Best-corrected visual acuity at the last follow-up was considered the final visual outcome. Data were analyzed with SPSS version 13.0 (SPSS, Inc., Chicago, IL). Results of statistical tests were considered statistically significant for P < .05. Almost all patients (89.1%) were male with a mean age of 14.3 ± 8.5 years. There was preponderance of young patients, with 63.0% (29) of the patients being younger than 15 years. In addition to their ocular injuries, 23 patients (50.0%) also had eyelid and/or facial burns. The most common initial anterior segment injuries were open-globe injuries (42, 79.3%), conjunctival burns (16, 30.2%), and foreign bodies (18, 34.0%). Others were traumatic cataract, lens subluxation and dislocation, and vitreous hemorrhage. Management after first aid included pars plana vitrectomy (9, 17.0%), aspiration of cataract (18, 34.0%), retinal reattachment (8, 15.1%), and enucleation. Amniotic membrane grafts were used in 11 patients (20.8%) with serious conjunctiva burns and corneal contusions and abrasions who were thought to have a good prognosis. Fireworks-related ocular injuries included a variety of clinical manifestations. Examinations such as B scan, optical coherence tomography, and ultrasound biomicroscopy helped to make a correct diagnosis and plan further treatment. Fireworks-related ocular injuries commonly affect young male subjects of Southern China. Visual outcomes were frequently poor and visually devastating. Laws should be passed to forbid the personal use of fireworks in China, and public education on the sale and use of fireworks should be increased.

Causes of eye burns in children

OBJECTIVE

Eye burns can cause significant ocular morbidity and miss early detection if unsuspected. The objective was to ascertain the reported causes of burns to the eyes in children.

METHODS

Published literature on eye burns in children was searched from 1950 to July 2008 in MEDLINE and from 1982 to July 2008 in CINAHL (Cumulative Index to Nursing and Allied Health Literature) to identify all reported cases.

RESULTS

Forty-two articles from MEDLINE, 5 from CINAHL database, and 6 from the reference lists were included in the analysis. Eye burns in children were caused by thermal, electrical, microwaved food and drinks, and solar hazards. Chemical agents included household cleaning agents, industrial chemicals, certain medications, agricultural chemicals, and some miscellaneous agents. Biological agents reported were millipedes, snake venom, vesicatory insects, and Manchineel tree sap.

CONCLUSIONS

This article shows that children experience eye burns due to many preventable causes. Public education strategies should be implemented to prevent eye burns in children.

The health and economic impact of fireworks-related injuries in Iran: a household survey following the New Year's Festival in Tehran

INTRODUCTION

Fireworks are used worldwide as a part of national and cultural celebrations. Personal use of fireworks is associated with serious injuries. The "Last Wednesday Eve Festival" is celebrated on the evening before the last wednesday of the Persian calendar year. In recent years, fireworks have been widely used during the festival, which has resulted in injuries. The aim of this study was to determine the incidence and risk factors of fireworks-related injuries associated with the Last Wednesday Eve Festival, in Tehran, Iran.

METHODS

A household survey of residents of greater Tehran, using a random cluster sampling design was performed. Number of fireworks-related injuries, expenditures for fireworks and medical treatment of fireworks-related injuries, length of hospital stay for treatment of these injuries and the personal property damage was gathered.

RESULTS

Interviews were conducted of 2475 households in greater Tehran. At least one member of 19.8% of these households had used fireworks during the 2007 Last Wednesday Eve Festival. Fireworks-related injuries were more common among households whose members had used homemade fireworks than among households whose members had used only commercially made fireworks (OR=16.5, 95% CI: 5.7-47.5). Forty-five households reported that they had sustained personal property damage caused by fireworks during the festival, costing a mean of US$ 36.60. Households with at least one injured member spent a mean of US$ 441.90 for medical care and a mean of US$ 70.80 for other expenses related to seeking medical care. The overall incidence of fireworks-related injury among household members was 0.2% (95% CI: 0.1-0.3%). Fireworks-related injury incidence was highest in the 10-19 age group. The total estimated number of fireworks-related injuries in Tehran during the 2007 Last Wednesday Eve Festival was approximately 17,000. Among the 20 injured individuals, 4 persons (20.0%) were hospitalised for a mean of 2.8 days.

CONCLUSIONS

The personal use of fireworks in Iran is associated with serious injuries and non-trivial economic costs. This study is the first to describe the incidence and economic costs of fireworks-related injuries in a major city in Iran using a population-based survey. To prevent these injuries, individuals should attend public fireworks displays conducted by professionals rather than engage in personal use of fireworks.

Ocular injuries and visual status before and after their management in the tribal areas of Western India: a historical cohort study

BACKGROUND

The authors present the epidemiology of ocular trauma and visual status before and after their management from 2003 to 2005 at a hospital in a tribal area of India.

METHODS

This was a historical cohort study. Persons exposed to open and closed globe types of injuries were reviewed. Ophthalmologists examined patients with the help of bio-microscope and also noted their visual acuity. Ocular Injuries were classified according to Birmingham Eye Trauma Terminology System (BETTS). Epidemiological profile, causes of injury, ocular status and visual gain after management were noted. Percentage scattergrams were plotted for both groups of injuries to evaluate visual gains. Binary logistic regression analysis was carried out to determine the predictors of visual outcomes following ocular trauma management.

RESULTS

Of the 2,607 persons with ocular trauma, 'open globe' and 'closed globe' types of injuries were found in 451 and 2,156 persons respectively. Within 24 hours of injury, only 1,355 patients (52%) had consulted ophthalmologists. Improvement in vision following management was noted in 133 persons (29.4%) with 'open globe' injuries and 217 persons (48.1%) with 'closed globe' injuries. In 845 patients (39.5%), vision could be retained at same level after management.

CONCLUSIONS

Agents and activities responsible for ocular injuries in our study differed from those reported in the industrialized countries. Late presentation was very common in our tribal area. Management improved the vision in eyes with trauma, but eyes with 'closed globe' type of ocular injuries had better results than 'open globe' type.

Pediatric fireworks-related injuries in the United States: 1990-2003

OBJECTIVE

Our goal was to describe the epidemiology of pediatric fireworks-related injuries among children aged 19 years and younger by using a nationally representative sample.

DESIGN

We performed a retrospective analysis of data from the US Consumer Product Safety Commission's National Electronic Injury Surveillance System from 1990-2003.

RESULTS

An estimated 85800 pediatric fireworks-related injuries were treated in US emergency departments during the 14-year study period. Injured children had a mean age of 10.8 years, and 77.9% were male. Fireworks users accounted for 49.5% of the injuries, whereas 22.2% of the injuries were to bystanders; however, user status could not be determined in 28.3% of cases. The overall fireworks-related injury rate decreased significantly during the study period, but subgroup analysis did not indicate consistent declines among all ages and types of fireworks. Injuries were most commonly caused by firecrackers (29.6%), sparklers/novelty devices (20.5%), and aerial devices (17.6%). The most commonly injured body sites were the eyeball (20.8%), face (20.0%), and hands (19.8%), and the most common injury type was burns (60.3%). Approximately 91.6% of all children with fireworks-related injuries were treated and released from hospital emergency departments, 5.3% were admitted, and 2.3% were transferred to another institution. Bystanders accounted for 13.3% of admitted cases and 20.6% of transferred cases.

CONCLUSIONS

Consumer fireworks cause serious preventable injuries among pediatric fireworks users and bystanders in the United States. Parents should be advised to take their children to safer public fireworks displays rather than allowing consumer fireworks to be used by or near their children. A national restriction of consumer fireworks, in accordance with the policy recommendations of the American Academy of Pediatrics, should be implemented to reduce the burden of fireworks-related injuries among children.

Visual outcome and ocular survival in open-globe injuries

AIM

To detect the risk factors that predicts final visual acuity, retinal detachment, and ocular survival after penetrating trauma.

METHODS

In a prospective case series study, 116 eyes with open-globe injuries were evaluated between 2001 and 2004. All data were filled in the questionnaire chart. Sex, age, involved eye, best-corrected visual acuity (BCVA), afferent pupillary defect (APD), location and wound length, cataract, iris prolapse, vitreous prolapse, retinal detachment (RD), intraocular foreign body (IOFB), vitrectomy procedure, and type of injury were evaluated as predisposing factors by logistic regression models for final visual acuity, RD, and ocular survival.

RESULTS

Low BCVA, RD, and vitrectomy procedure were detected significant in the final visual acuity of 20/200 or less. APD and vitrectomy procedure were statistically significant in the final RD. BCVA 20/250 or less, wound length >10mm, scleral and corneoscleral lacerations, vitreous prolapse, vitreous hemorrhage, RD, and sharp injury were correlated with decreased globe survival.

CONCLUSION

Low BCVA, APD, and vitrectomy procedure were effective in the visual outcome. RD and vitrectomy procedure were detected significant in the anatomic result. Establishment of predictors of visual outcome and ocular survival may assist clinicians in salvageable eyes for surgical repair.
