Ocular findings in asymptomatic amateur boxers.

A group of 25 active, asymptomatic, amateur boxers were examined to evaluate the nature and incidence of ocular pathologic conditions in amateur boxing. An approximately age-matched group of 25 men who were not boxers was used as a control group. The number of fights varied from 1 to 220 (mean 39.4), and the number of spar rounds from 20 to 600 (mean 192.5). Visual acuity was 20/20 in all subjects of both groups, except for one boxer with keratoconus. Intraocular pressure was below 20 mmHg in all eyes. In 19 (76%) boxers, pathologic anatomic findings were attributed to contusion trauma. Lesions of the anterior eye segment included injuries of the lid in 3 eyes (12%), angle abnormalities in 5 (20%), and slight lens opacities in 5 (20%). Posterior vitreous detachment was observed in 3 (12%) boxers and peripheral retinal scars were seen in 15 (60%). In 6 (24%) eyes, retinal tears or atrophic holes were detected. In the 7 (28%) boxers with lesions of the anterior eye segment, the posterior segment was also affected in 6 (85%). In the control group, an atrophic hole was found in one (4%) patient with no other ocular pathologic findings.(ABSTRACT TRUNCATED AT 250 WORDS)

Surfing-related ocular injuries.

PURPOSE: This report evaluates the clinical characteristics of surfing-related ocular trauma to learn the nature of such injuries and propose possible preventive measures. METHODS: The authors reviewed 11 cases of surfing-related eye injuries caused by direct trauma from the surfboard, studying their mechanism of injury, the associated ocular complications, and the anatomic and visual outcomes of surgical repair. RESULTS: Surfing-related ocular injuries occurred exclusively in young males (mean age, 24.8 years; range, 14-37 years). The mechanism of injury most frequently responsible was impact with the sharp nose of the surfboard following a fall. Serious posterior segment complications were observed in all 11 patients, with nine patients suffering ruptured globes. Despite immediate medical attention, five patients did not recover ambulatory levels of visual acuity (>5/200). CONCLUSIONS: Surfing-related ocular trauma presenting to the retinal specialist typically leaves the patient with a permanent visual disability. Important factors contributing to these high-velocity injuries include the sharply pointed nose of the surfboard and the leash keeping the surfer in close proximity to the board following a fall. A simple modification in surfboard design such as blunting the sharp nose of the surfboard, or appropriate protective guards fitted over the surfboard nose, should lessen the severity of such injuries.

Eye injuries caused by cow horns.

PURPOSE: To assess ocular injuries caused by cow horns; to investigate clinical findings, treatment, and visual outcome in a population of dairy farmers; and to propose possible preventive measures. METHODS: A retrospective review was conducted to identify patients seen over a 45-month period with cow horn-inflicted eye injuries. Eleven patients were identified and their charts reviewed for demographics, mechanism of injury, initial and final visual acuity, surgeries performed, and anatomic outcome. RESULTS: The mean age of the patients was 64 years. Seven patients had open-globe injuries with vitreous hemorrhage. In five cases, pars plana vitrectomy was performed. Final best-corrected visual acuity was < or = hand motion in five patients, between 20/160 and 20/80 in three patients, and better than 20/32 in three patients. CONCLUSION: The majority of the cow horn injuries studied caused severe permanent impairment of vision. Owing to the blunt nature of the horns, a significant amount of energy is imparted into the eye. To prevent these injuries, coagulation of the horns should be performed 2 weeks after a calf's birth or farmers should be advised to wear safety glasses.

Eye Injury Registry of Alabama (preliminary report): demographics and prognosis of severe eye injury.

Each year an estimated 1.3 million Americans suffer eye injuries. There is little information in the literature regarding the prevalence, demographic characteristics, and prognosis of these patients. The Eye Injury Registry of Alabama (EIRA) serves as the first and only statewide system of its kind for the collection of information on serious eye injuries. We have analyzed 736 cases of serious eye injury (injury involving permanent structural or functional change) accumulated by the EIRA between August 1982 and May 1986. Prognosis was found to be related to early diagnosis and initial vision. Individuals with follow-up vision of 20/40 or better were found in all early diagnostic groups, and 13% of patients with no light perception on initial examination had some improvement on follow-up. The worst visual prognosis was among those patients suffering blunt eyeball rupture, of whom 40% had no light perception and 25% regained vision of 20/100 or better.

Field evaluation of polycarbonate versus conventional safety glasses.

Of all the causes of eye injury, gunshot has recently been cited as resulting in the highest rate of blindness and the lowest rate of visual recovery. Many of these cases are hunting accidents in which safety glasses could have prevented or lessened ocular damage. To evaluate the effectiveness of various types of safety glasses, we fired a Remington automatic shotgun at mannequin heads fitted with one of four types of safety lenses. From a distance of 10 yards, only polycarbonate lenses provided even partial protection. At 30 yards, polycarbonate and heat-treated lenses provided the best protection, whereas chemically treated and CR39 lenses provided significantly less protection. We recommend that hunters using shotguns in areas of poor visibility wear widely available polycarbonate safety glasses as well as "hunter's orange" to minimize their risk of devastating ocular gunshot injury.

Eye injuries in women's lacrosse players.

OBJECTIVE: To determine the prevalence of eye injuries among intercollegiate women's lacrosse players as well as the level of play, specific play settings, and particular mechanisms associated with these injuries. DESIGN: Anonymous, retrospective, survey. SETTING: Intercollegiate lacrosse tournament. PARTICIPANTS: Collegiate and postcollegiate women's lacrosse players. MAIN OUTCOME MEASURES: Self-reports of eye injuries, injury circumstances, treatment received, playing time missed, and continuing problems were recorded. RESULTS: Surveys were collected from 667 players from 34 teams (83% of players listed on rosters). A total of 125 injuries were reported among 84 players (12.6%). Injuries occurred equally in high school and college. Athletes were injured most frequently in games (41 injuries) and practices (38 injuries), with 17 players injured during the off-season. Several mechanisms of injury were noted. Fifty-three women sustained injuries requiring medical attention. Of those athletes injured, 23 missed 1-5 days and 9 players missed more than 5 days. Four athletes (4.8%) reported residual problems from an eye injury sustained while playing lacrosse. CONCLUSIONS: Eye injuries are occurring more frequently than current surveillance data suggest. Because injuries are seen at all levels of play, in many different situations, and by multiple mechanisms, mandatory eyewear is needed to prevent serious eye injuries in women's lacrosse.

Welder eye injuries.

During 1985, welders submitted 21% of all claims for eye injuries received by the Workers' Compensation Board of Alberta. Since then the proportion of similar claims has remained high. A descriptive study of welder eye injury claims reveals that, although most injuries are reversible (55% of workers return to work in less than 2 days and 95% in less than 7 days), some workers sustain permanent visual impairment. Eye injuries occur most frequently in metal-work industries, and cold particles, most often metal, are the most common source of injury. Preventive measures should stress the importance of wearing eye protection constantly while working with metal pieces and in metal industries. Goggles probably should not be removed upon extinguishing the welding torch.

Prevalence of and potential risk factors for symptoms associated with insecticide use among animal groomers.

Pet groomers make numerous insecticide applications during the flea season, but few studies have examined their health complaints. The Pesticide Control Program of the New Jersey Department of Environmental Protection conducted a health and safety survey of this population. All licensed pet applicators in New Jersey were contacted, as were New Jersey veterinarians listed as pet-animal practitioners by the American Veterinary Medical Association. Approximately 36% of the respondents indicated that during the 1994 flea season, they had experience at least one of the 17 symptoms associated with insecticide application. Central nervous system symptoms (headache, dizziness, or confusion) and skin symptoms (skin rash or numbness/tingling) were reported most frequently. Logistic regression results suggest that applications per season, years as an applicator, certain hygiene variables, certain classes of products, and status of applicator (veterinary vs veterinary) are potentially important risk factors.

Mechanical ocular trauma.

Mechanical ocular trauma remains a leading cause of visual loss and blindness and often affects young individuals. Approximately 75% of people with trauma-induced visual impairment are monoculary blind. Furthermore, the human, social, and economic consequences of eye injuries are enormous in all parts of the world. Because most eye injuries are preventable, efforts could be spent much more effectively on preventing eye injuries rather than treating them. It is important to make the public aware of the benefits of using protective equipment, which is almost universally available, and was the main concern of most of the authors reporting on ocular trauma in the past year. Of great importance seems to be the introduction of an international standardized classification of ocular trauma.

Can UV radiation-blocking soft contact lenses attenuate UV radiation to safe levels during summer months in the southern United States?

PURPOSE: Peak solar UV radiation (UVR) intensities are typically experienced in summer months. People living in the southern states of the United States, where the UVR frequently exceeds the recommended minimum erythema dose (MED), are at particular risk, especially outdoor workers. The present study analyzed summertime MED readings in Houston, TX, to assess the frequency of intensities regarded as unhealthy. The study also sought to assess whether UV-blocking hydrogel contact lenses provide ocular protection from these high doses. METHODS: Readings, taken at midday using a UVR biometer, were analyzed to assess the potential UVR risk. The spectral response of the meter, modified by the spectral transmission curves of the contact lenses, allowed us to mathematically assess the ocular protection provided. In addition, ambient UVR measurements were taken at midday, using a portable UVR radiometer. The detector was adapted so that a standard diameter hydrogel contact lens could be placed over it to quantify the UV-blocking capabilities of the lens. RESULTS: The MED readings showed that the recommended safety standards were exceeded approximately at local midday 90% of the time. Model calculations and empirical data demonstrated that contact lenses attenuated the MED readings by up to 90%, bringing them well within the recommended Environmental Protection Agency safety standards. CONCLUSION: The efficacy of the model used in this study was verified through direct comparison of the modeled and measured data. UV-blocking hydrogel soft contact lenses reduce the MED to the human eye and therefore limit the lifetime ocular dose. These lenses are highly recommended to prevent the development of UVR-related ocular pathologic conditions.

A simple approach to industrial laser safety.

Industrial applications of lasers include marking, welding, cutting, and other material processing. Lasers used in these ways have significant power output but are generally designed to limit operator exposure to direct or scattered laser radiation to harmless levels in order to meet the Federal Laser Product Performance Standard (21CFR1040) for Class 1 laser products. Interesting challenges occur when companies integrate high power lasers into manufacturing or process control equipment. A significant part of the integration process is developing engineering and administrative controls to produce an acceptable level of laser safety while balancing production, maintenance, and service requirements. 3M Company uses a large number of high power lasers in numerous manufacturing processes. Whether the laser is purchased as a Class 1 laser product or whether it is purchased as a Class 4 laser and then integrated into a manufacturing application, 3M Company has developed an industrial laser safety program that maintains a high degree of laser safety while facilitating the rapid and economical integration of laser technology into the manufacturing workplace. This laser safety program is based on the requirements and recommendations contained in the American National Standard for Safe Use of Lasers, ANSI Z136.1. The fundamental components of the 3M program include hazard evaluation, engineering, administrative, and procedural controls, protective equipment, signs and labels, training, and re-evaluation upon change. This program is implemented in manufacturing facilities and has resulted in an excellent history of laser safety and an effective and efficient use of laser safety resources.
