Sports eye injuries a preventable disease.

Each year, sports are responsible for over 100.000 preventable eye injuries. A face-protector standard was developed for hockey. Certified protectors effectively eliminated eye and face injuries to 1,200,000 players averting a projected 70,000 injuries and saving over $10,000,000 in medical expenses annually. The principle of absorbing energy in a protective device before the eye is injured is applied to other sports (racket sports, baseball, basketball). Recommendations are made on eye protection for athletes. Better data collection and standards for sports and children's eyewear are encouraged.

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)

Ocular injury in hurling.

OBJECTIVES: To describe the clinical characteristics of ocular injuries sustained in hurling in the south of Ireland and to investigate reasons for non-use of protective headgear and eye wear. METHODS: Retrospective review of the case notes of 310 patients who attended Cork University Hospital or Waterford Regional Hospital between 1 January 1994 and 31 December 2002 with ocular injuries sustained during a hurling match. A confidential questionnaire on reasons for non-use of protective headgear and eye wear was completed by 130 players. RESULTS: Hurling related eye injuries occurred most commonly in young men. Fifty two patients (17%) required hospital admission, with hyphaema accounting for 71% of admissions. Ten injuries required intraocular surgical INTERVENTION: retinal detachment repair (5); macular hole surgery (1); repair of partial thickness corneal laceration (1); repair of globe perforation (1); enucleation (1); trabeculectomy for post-traumatic glaucoma (1). Fourteen eyes (4.5%) had a final best corrected visual acuity (BCVA) of <6/12 and six (2%) had BCVA <3/60. In the survey, 63 players (48.5%) reported wearing no protective facemask while playing hurling. Impairment of vision was the most common reason cited for non-use. CONCLUSIONS: Hurling related injury is a significant, and preventable, cause of ocular morbidity in young men in Ireland. The routine use of appropriate protective headgear and faceguards would result in a dramatic reduction in the incidence and severity of these injuries, and should be mandatory.

An uncommonly serious case of an uncommon sport injury.

BACKGROUND: A 55 year old man sustained a severe ocular injury when hit by a cricket ball even though he was wearing a helmet. METHODS: A suprachoroidal haemorrhage was drained and dense intravitreal blood was removed. An inferior buckle was applied with the use of intraocular gas. A macular haemorrhage resolved slowly. RESULTS: Despite several surgical procedures over 1.5 years, the final visual acuity of the patient was only 6/60 because of a dense macular scar. CONCLUSIONS: Helmets worn as protection when playing cricket need to be designed better and be of better material. Eye protection should be worn at all levels of play.

Eye injuries in Canadian hockey.

Increasing public concern led the Canadian Ophthalmological Society, in January 1974, to form a committee to study the incidence, types and causes of hockey eye injuries and to devise means of reducing such injuries. Retrospective and current studies were undertaken, and face protectors were tested. In both pilot studies, sticks were the commonest cause and the highest number of eye injuries was in players 11-15 years old. An average of 15% of all injured eyes were rendered legally blind. Cooperation with hockey authorities has resulted in changed rules and their sticter enforcement, and formulation of standards for face protection approved by the Canadian Standards Association. In this interim report the committee recommends that all amateur hockey players wear eye protectors and urges ophthalmologists to participate in efforts to improve the design of protective equipment.

Through a glass, darkly.

The technology available in today's auto-darkening welding helmets was the stuff of science fiction to welders 30 years ago. A single lens capable of darkening automatically to a variable, preset shade level the instant an arc is struck would have sounded about as realistic as a "Star Trek"-style "transporter" or a cell phone that can take pictures. "It would have been complete and total science fiction," said Kevin Coughlin, president of Hoodlum Welding Gear, Minneapolis. "The technology really didn't exist, so it would be like me telling you your car will be flying in 20 years--you'd look at me and laugh. Even 25 years ago, if someone had told me [the lens] would go from clear to dark when you spark, I'd have said, 'Yeah, right, sure it does.' "

Visual acuity of the U.S. Navy jet pilot and the use of the helmet sun visor.

Visor wear habits, evaluative comments and vision test data were obtained from interviews of 126 Navy fighter pilots. The interviews revealed that many pilots use their helmet sun visor whenever they fly, some use it only during certain flight operations, and others never use it. Study 1 (conducted at 343 cd/m2) revealed a decrease in low contrast visual acuity attributable to helmet sun visor use in the presence of a glare source. These findings prompted a second study of the visual effects of visor transmittance. Low-contrast spot detection, acuity, and contrast sensitivity were measured at an operationally realistic daytime illumination level (6870 cd/m2) in subjects viewing through filters ranging from 6.3% to 50.1% transmission. (Standard visor transmission is 12 +/- 4%.) Results showed that filter density, and consequently the illuminance reaching the eyes, could be varied over a wide range without critically affecting these visual functions. Prevailing environmental illuminance should be considered when selecting sun visors or sunglasses. These results have implications for optimizing visual performance through visors.
