The incidence of eye injuries in the coal mining industry in one British Coal Area in 1 year is presented and discussed. The discussion reviews the literature on eye injuries generally. The problems of ensuring adequate eye protection in mining operations are described: plans for a future survey to pinpoint critical areas are outlined.
Army, Navy, and Air Force safety center ground eye injuries were evaluated from fiscal year 1988 through fiscal year 1998. The U.S. Army Safety Center data revealed that the average Army military eye injury mishap caused a loss of 6.1 days from work, at a cost averaging 9724 dollars. The U.S. Navy Safety Center data showed that the average Navy military eye injury mishap caused a loss of 5.9 days from work, at a cost averaging 4222 dollars. The Air Force Safety Center data revealed that the average Air Force eye injury mishap caused a loss of 4.7 days from work, at a cost averaging 3196 dollars. Comparing safety center data with Defense Medical Surveillance System data exposed an underreporting of safety center data by at least 250%. To improve accurate meaningful data collection, an automated eye injury collection system should be initiated.
Union administrative records were combined with workers' compensation data to identify a cohort of 12,958 active union carpenters, their person-time at risk, and their documented work-related eye injuries between 1989 and 1995 in the state of Washington. The injuries were described using ANSI codes for injury nature, type (mechanism), and source or object associated with the event. Injuries which resulted in paid lost time from work were also described based on the ICD-9 codes attached to claims for their medical treatment. Overall rates of filing compensation claims for eye injuries as well as age, gender, and union local specific rates were calculated. To identify high risk subgroups and explore incident and recurrent events, the person-time and events were stratified by age, gender, time in the union, claim status, and predominant type of work of the union local with which each carpenter was affiliated for multivariate analyses with Poisson regression. Eye injuries were responsible for 12 percent (n = 1730) of workers' compensation claims during this time period, exceeded only by back and finger injuries. Thirty-one claims resulted in paid lost time from work and these cases accounted for one-third of all costs for medical care for eye injuries. At least 10 percent of all medical costs for eye injuries and 35.5 percent of medical costs for eye injuries which resulted in paid lost time were associated with injuries sustained while hammering--a very common carpenter exposure. Claims were filed at an estimated rate of 6.1 per 200,000 hours worked. Individuals with previous compensation claims for eye injuries had rates of injury 1.6 times higher than individuals without previous eye injuries. Rates decreased significantly with age and time in the union. Eye injuries among these union carpenters were very common, but the rate of injuries severe enough to require paid time off work was quite low. These findings raise questions about factors which might influence the failure to use appropriate protection including availability and acceptability of eye protection, use by peers, and perception of risk.
PURPOSE: To determine the epidemiology and outcomes of penetrating eye injuries in a rural Australian setting. METHODS: A retrospective study of an 11 year period to identify 77 cases of penetrating eye injury in Lismore, New South Wales. RESULTS: The commonest cause of penetrating eye injury was fencing wire followed by hammering metal. The average age was 32.6 years, and males were involved in 88% of cases. A final visual acuity of 6/12 or better was achieved in 61% of cases. Enucleation was performed in 14%. Visual outcome was best for wounds involving the cornea only. CONCLUSIONS: Penetrating eye injuries are potentially devastating to vision, but with modern surgical techniques patients are likely to achieve reasonable vision. Prevention requires education to ensure adequate protective measures are taken in potentially hazardous settings.
PURPOSE: To describe the circumstances associated with eye injury from an ocular examination of two patients with Tourette syndrome. DESIGN: Case reports. METHODS: A 21-year-old man and a 24-year-old man had sudden and unpredictable movement during an eye examination, causing conjunctival laceration and hemorrhage abrasion in the first patient and a corneal abrasion in the second patient. RESULTS: With topical antibiotics for both patients and patching of the eye for the 24-year-old patient, healing was uncomplicated. CONCLUSIONS: Patients with Tourette syndrome are at risk of eye injury when an unanticipated tic movement occurs during eye examination. Physician precautions, particularly mental preparedness for sudden jerking movement, should be taken when examining patients with Tourette syndrome.
The eye injuries resulting from motor vehicle accidents over the three years, 1975 to 1977 inclusive are considered. A high incidence of severe eye injury produced by safety windscreen glass continues. The results of this survey are compared with a survey of the period 1970 to 1974 inclusive.
The prevention of eye accidents is one part in the whole field of occupational safety which can be carried out in the most clear-cut manner. Solution patterns are easily mapped out and applied to use. Eye accidents occur mostly in the metal industry but are spreading through the whole field of industry from year to year. The principles of the prevention of eye accidents can be applied as an example for many other branches of occupational safety and thus models of functions created by the enterprise for sight protection can be projected to other prevention points.
OBJECTIVE: To: (i) determine the magnitude and describe the spectrum of sports-related eye injuries; (ii) compare the sporting profile variations within Australia and overseas; and (iii) provide recommendations to help decrease the frequency and severity of eye injuries in sports. DESIGN AND SETTING: Descriptive study of sports-related eye injuries identified from a cross-sectional survey of ocular trauma treated in an eye hospital during a two-year period from November 1989 to October 1991. RESULTS: Although sports injuries comprised only 5% of all eye trauma, they accounted for a disproportionately high ocular morbidity, representing 22% of hospital admissions. Most patients were admitted for hyphaema (81%), but there were eight ruptured globes and 20 other cases required surgical repair. For those hospitalised for serious injuries, 19% were legally blind (visual acuity < or = 6/60) and 10% had visual acuity between 6/18 and 6/36 initially, with 29% of patients recording a visual loss in excess of 50% incapacity (< or = 6/18) at three months after injury. CONCLUSION: Eye injuries were most frequently caused by squash, badminton, Australian Rules football and cricket, a sports profile distinctly different from those of the United States and United Kingdom. That none of the players in may study had worn correct eye protection offers a wide scope for preventing injuries in what should be safe recreational pastimes.
Eye injuries in sport are a continuing preventable problem. An investigation into sport injuries in rural Ireland shows hurling to be the most dangerous pastime, and this is compared and contrasted with other local games. Forty-five consecutive injuries sustained in organised sport requiring admission to hospital over a 4-year period were studied. 40% were due to hurling. Over three-quarters of the 45 patients recovered 6/6 vision or better. The costs to the community of such eye injuries are discussed.
The purpose of this paper is to elucidate the incidence of eye injuries with respect to occupant age in frontal automobile crashes as well as to investigate possible injury mechanisms of the elderly eye and the effects of lens stiffness. The National Automotive Sampling System was searched from years 1993-2000 for three separate occupant age groups of 16-35 years old, 36-65 years old, and 66 years old and greater in order to compare the total number of weighted occupants who sustained an eye injury to the number of occupants who sustained an eye injury per age group. Three separate impact scenarios simulating a foam particle (30 m/s), a steering wheel (15 m/s), and an air bag (67 m/s), were applied to a finite element eye model in order to elucidate the effects of aging on the eye when subjected to blunt trauma. The lens stiffness of the model was varied according to human lens stiffness values determined for each age group. Occupants aged 66 years old and greater were two to three times more likely to incur an eye injury than younger occupants. The computational eye model demonstrated that increased risk was related to the increasing stiffness of the lens, producing up to a 120% larger stress in the ciliary body.
Data about eye traumatism at the Republican Ophthalmologic Center are presented. 791 patients have been investigated: 52.3% with penetrated wounds; in 19.3% cases we detected foreign intraocular bodies. Fibrinolysin and dexamethazone have been introduced during operation in the case of fibrinoplastic inflammatory process with crystalline lens masses in the anterior camera. As a result we noted a positive evolution in the postoperative period.
PURPOSE: To assess the frequency, causes, mechanisms, and functional outcomes of eye injuries in childhood. METHODS: A retrospective analysis of the hospital files of patients younger than 12 years admitted to the Institute of Ophthalmology of Verona University for eye injuries from January 1, 1988, to December 31, 2000. RESULTS: Eighty-eight cases of eye injuries (69 [78%] boys, 19 [22%] girls) were identified. The mean age at admission was 7.2 years. The most frequent causes of eye injuries were domestic accidents in patients younger than 6 years (25%) and accidents at play in those older than 6 years (35%). Scissors were the most frequent causative agents in children under 6 and toys, stones, and ball injuries in those over 6. Diagnoses, therapies implemented, ocular complications, and outcomes are reported. CONCLUSIONS: The major causes of eye injuries in childhood are preventable; thus more adequate adult supervision and educational and legislative measures are necessary and useful in order to reduce prevalence and morbidity of these accidents.
Patients who were admitted to Auckland Hospital with an eye injury during 1975 have been considered. The cause of injury, type of injury and visual outcome have been recorded. At least 60 percent of the eye injuries occurred during leisure activities. In this study more patients were admitted with an hyphaema following sports injuries and fewer admitted after motor mower injuries than in an earlier study. Some preventative measures in eye injury are discussed.
As more Canadians are taking up squash the incidence of eye injuries is increasing dramatically. Over 2-1/2 years, 23 cases from one urban practice were examined. Almost half of the group required inhospital treatment. Five patients sustained a permanent decrease in vision; these cases involved three corneal scars, one cataract and one macular cyst. Patients wearing glasses or hard contact lenses appear to be more susceptible to serious eye injury. Experience does not appear to reduce the likelihood of eye injuries; the patients in this study had played squash for 5.6 years on the average. Consequently the medical profession must take the lead by encouraging squash players to use protective equipment now available to reduce the incidence of these injuries that pose so much personal hazard.
BACKGROUND: Eye injuries affect a large proportion of the population and are expensive to treat. This article presents a parametric analysis of experimental data to determine the most significant factors for predicting ocular injuries or tissue lesions. METHODS: Using logistic regression, statistical values were generated to determine significant projectile characteristics for predicting ocular injury in published studies. Projectiles included BBs, metal rods, and foam particles with velocities ranging from 2 m/s to 122 m/s. RESULTS: A normalized energy (energy per projected area) value was found as the best predictor for ocular injury. Using this predictor, a 50% injury risk of corneal abrasion, lens dislocation, hyphema, retinal damage, and globe rupture was found to be 1,503 kg/s(2), 19,194 kg/s(2), 20,188 kg/s(2), 30,351 kg/s(2), and 23,771 kg/s(2), respectively. CONCLUSION: Normalized energy was the most significant predictor of injury type and tissue lesion. This finding is of great value for history-taking management triaging and as a design aid to minimize the risk of ocular injury for consumer products.
