Safety considerations and safety protocol for laser surgery.

The critical importance of laser safety depends on a precise knowledge of the physics of each type of laser and on the tissue effects each type produces in the constantly changing environment during surgery. The considerations involved in using the most common lasers--safety guidelines, general protocol, and specific measures--are outlined.

Eye injuries in athletics and recreation.

Sports-related eye injuries represent a significant eye health hazard worldwide. In the USA, it is estimated that eye injuries from sports account for more than 100,000 physician visits per year at the cost of greater than $175 million. The sports responsible for the greatest number of injuries are baseball, ice hockey, and racquet sports. In the USA there are over 189 million participants in these sports with a disproportionate number (one-third) of injuries involving the pediatric population. The most common injuries are abrasions and contusions, followed by more serious injuries, including hyphema. Substantial reduction in the incidence of eye injuries through prevention has been demonstrated in the sport of hockey which can serve as a model for other sports. Specific criteria for protective eyewear must be developed. Polycarbonate plastic lenses and frames which are sturdy and impact resistant provide optimal protection. Lensless goggles, street wear and spectacle correction glasses do not provide adequate eye protection. The ophthalmologist's role in preventing sports-related eye injuries includes addressing particular sports participants needs, identifying one-eyed athletes, and informing patients of the need for protective eyewear.

Intensity/frequency indicator for detection in space: the high values of the incident solar or laser optical radiation in comparison with the appropriate maximum permissible exposure.

The solar or laser optical radiation impact to humans in space depends on the intensity, on the exposure type (direct or indirect) & duration and on the matching of radiation wavelength to tissue characteristics. The main protection factor in space is the application of exposure limits. This paper describes the main biological optical interaction parameters, the optical exposure hazards and the development of a small active lightweight indicator, with output beeper rate depended to the ratio of optical irradiance/exposure limit. The indicator may be used as warning element on the side of helmets, goggles, spectacles, etc, with low power consumption. Electronically the indicator is an intensity/frequency converter, based on the value of the ratio of exposure/exposure limits, with audio & light beepers like the indication output of the ionizing (radioactive) radiation monitors.

Improvement of apraxia of eyelid opening by wearing goggles.

Apraxia of eyelid opening (ALO) is a non-paralytic motor abnormality characterised by difficulty in initiating the act of eyelid opening without blepharospasm. We found that wearing goggles improved the difficulty of opening eyes in two patients with ALO with parkinsonism. Wearing goggles is a simple method for improving daily life in patients with ALO.

The effects of a penetrating metallic foreign body on a pseudophakic eye.

The penetration of a pseudophakic eye by a high-speed metallic foreign body is reported. The path of the steel missile was interrupted by the intraocular lens, which was fixed within the capsular remnant, preventing missile penetration into the posterior segment. Although the foreign body was removed from the anterior chamber without immediate sequelae, several months later a peripheral retinal detachment occurred. Prompt recognition and treatment resulted in the retention of excellent pseudophakic vision. The importance of postoperative protective eyewear is emphasized.

Do motor vehicle airbags increase risk of ocular injuries in adults?

PURPOSE: This study was undertaken to evaluate the risk of eye injury in motor vehicle accidents in which airbags deploy. An attempt was made to assess the possible associations between eye injuries and eyewear in these accidents. DESIGN: Retrospective observational case series and literature review with analysis. PARTICIPANTS/METHODS: We conducted a literature review of 62 case reports and articles describing 110 adult cases of eye injury after deployment of an airbag and examined two Finnish accident cohorts. The fatal accident series (FAS; fatal injuries with one or more cars involved) included 121 individuals sitting behind an airbag that deployed (65 survivors), and the Airbag study (AB; nonfatal, relatively serious accidents) included 210 individuals (survivors). MAIN OUTCOME MEASURES: The type of eye injury, eyewear, and crash dynamics were studied in each of the reviewed case reports. The fatal accident series and AB studies were analyzed to disclose the eye injuries and use of eyewear and to estimate their possible relation to deployment of airbags. RESULTS: Analysis of the published reports revealed that airbag-induced eye injuries were not more frequently reported among wearers of eyeglasses than among nonwearers. However, open-eye injuries were reported three times more often among eyeglass wearers (P = 0.04), whereas all injuries from airbag chemicals occurred among nonwearers. With the exception of one orbital fracture with hyphema, all eye traumas (n = 7) in the FAS and AB cohorts were mild (eyebrow laceration, lid contusion, bruising). The risk of airbag-related eye injury was 2.5% for any eye injury and 0.4% for severe eye injury. In single accidents when seat belts were used, the risks were 2.0% and 0.5%, respectively. In the accidents from the FAS data no difference was observed in the risk for eye injury between survivors in incidents involving airbag deployment and incidents not involving airbags. This risk was not found to be greater among eyeglass wearers. CONCLUSIONS: Despite reported cases in the literature, we found that the risk of severe eye injury from airbags was very low (0.4%) in fatal or relatively serious accidents. Eyewear did not seem to increase this risk but might interfere with the injury pattern.

A new eye shield based on an optimized pinhole array.

The new eye shield described here incorporates the principles of a compound array that provides a significant improvement in vision (from hand movements to 20/100 or better) in a nonaccommodative eye, while retaining all other properties (protection, ventilation, reduction of glare) of eye shields used currently. It is recommended for routine use in patients after intraocular surgery and pupillary dilatation.

Eye protective techniques for bright light.

There are two principal methods to protect the retina from light damage: filtration, and brightness reduction. Since short-wavelength light and ultraviolet radiation are the most hazardous, filters that strongly attenuate wavelengths less than 500 nm can be quite effective. As infrared radiation may enhance photochemical light damage of the retina, filtration of infrared radiation is also desirable. Finally, since the eye must focus incident light on the retina, the brightness (radiance) of a source plays an important role in determining the degree of hazard of a light source. Diffusing the light source can greatly reduce the risk of injury.

Prevention of ocular gunshot injuries using polycarbonate lenses.

Two patients lost three eyes, and one his life, secondary to ocular gunshot wounds. In both patients, the pellets gained entry into the central nervous system through the eye and orbital bones despite only superficial wounds to other areas of the body. These tragic injuries prompted a study of polycarbonate lenses to determine their effectiveness in preventing small caliber ocular gunshot wounds. This investigation determined that 3.0 mm and the 2.2 mm polycarbonate lenses could prevent such injuries at distances greater than 15 yards. In comparing the two lenses, it was found that the 3.0 mm lens sustained less damage at 70 degrees F, but the 2.2 mm lens was more resistant to penetration at 32 degrees F. Since most hunting is done in the fall and winter months, the brittle nature of the thicker lens is significant. Polyamide sports frames with a posterior rim were also tested and found to prevent posterior lenticular expulsion at 15 yards. Standard acetate frames were shown to be ineffective in this regard at 30 yards.

Anisometropic amblyopia.

One hundred twenty-four patients with anisometropia of 1 diopter or greater and amblyopia were reviewed as to the type and amount of anisometropia, whether or not they had consulted with an ophthalmologist, visual acuity before and after treatment, and type of treatment. The patient population was divided into five groups according to the type of anisometropia. Eighty-two percent of all patients reached a visual acuity of 20/40 or better. Eighteen percent of all patients reached a visual acuity of 20/20. The best visual acuity obtained was not found to be related to the degree of anisometropia or the age at which treatment was begun. Patients with myopic and compound myopic astigmatism/mixed astigmatism anisometropia had poorer visual outcomes. There was a strong positive correlation between the initial visual acuity and the best visual acuity obtained (P = 0.0001).

Shotgun eye injuries. Ocular risk and eye protection efficacy.

BACKGROUND: Little is known about the efficacy of shotgun eye protection. Shotguns can easily propel pellets with enough energy to penetrate the human eye, and a large percentage of shotgun eye injuries occur during shotgun sports such as hunting, trap, skeet, and sporting clays. Many of these injuries are preventable with proper eye protection. Although it is known that polycarbonate is the best lens material for shotgun eye protection, there has been no research that addresses the vision protective system design and its influence on eye protection. METHODS: A field study was performed during which shotshells were fired at 1:1 scale photographs of human faces to determine the risk of ocular trauma. The protective efficacy of three types of polycarbonate protective eye wear (standard industrial safety glasses with snap-on side shields, wrap-around racket sport glasses, and three-piece glasses with integral side shields) was tested by firing shotshells at them at various distances. Both frontal and side protection was evaluated. RESULTS: Results showed that the eye is at a high risk (55% to 100%) of being hit with shot pellets at ranges of 15 to 40 yards. It also was determined that the protective eye wear will give good frontal eye protection from shotgun pellets but integral side shields and a headband are necessary to obtain adequate side protection. CONCLUSION: These findings, coupled with the poor visual prognosis of ocular shotgun injuries, indicate that polycarbonate protective eye wear with integral side shields and headbands should be worn by all involved with shotgun sports.
