UV-protective sunglasses for UVA irradiation protection.

BACKGROUND: Eye protection with UVA-blocking solar shields is recommended on the day of PUVA treatment and the following day for our patients; however, many patients found this eyewear cosmetically unacceptable. METHOD: We investigated 34 pairs of sunglasses to determine their suitability for providing adequate protection. The method used was modified from the technique used by Moseley et al. in 1988. RESULTS: We found that 21 (61.8%) of the 34 pairs of sunglasses and only 9 (53%) of the 17 pairs of sunglasses used by our patients were "satisfactory." Expensive brands and polarizing sunglasses do not guarantee optimal UVA protection. CONCLUSION: We recommend that all patients should use wrap-around solar shields for optimal eye-protection, while undergoing PUVA treatment. The availability of more cosmetically acceptable glasses will encourage better patients' compliance to protect their eyes with optical aids.

Ocular complications of PUVA therapy.

PUVA, the combination of psoralen and long wave ultraviolet radiation is widely used in the management of psoriasis, vitiligo and several other dermatological disorders. The potential for long term treatment to cause ocular damage remains to be determined and despite the large numbers of patients who have received PUVA treatment, development of cataract is exceedingly rare. This paper discusses cataract formation, reviews the literature concerning the ocular complications of PUVA therapy and proposes guidelines for ocular protection during photochemotherapy.

Eye protectors for squash players.

Eye injuries have occurred to squash players wearing commercial open-type eyeguards, suggesting inadequacies in their design. This study reports experimental observations on the deformation of high velocity squash balls at an aperture simulating an open-type of eyeguard. Open eyeguards were shown to be inadequate in preventing eye trauma by ball-strike. Recommendations for improvement of eyeguard design have been made.

Sunglasses: are they necessary in Christchurch?

Concern over potential eye injury from sunlight prompted this study to see if the levels of sunlight in Christchurch posed a particular risk to our population's eyes, whether the populace was aware of any risk and whether effective sunglasses were freely available to the public. While there has been a 4% to 9% increase in UV radiation since 1969 due to global ozone depletion, no firm evidence was found that focal ozone depletion was a particular problem in New Zealand. Christchurch residents were poorly informed about the ocular hazards of sunlight. A questionnaire completed by 200 adults disclosed 32% were unaware of the particular danger of UV light and only 3% knew that snow blindness, eclipse burns and cataracts could all be caused by sunlight. Fifty-four sunglasses were analysed for labelling and for transmission characteristics of their lenses. The standard of labelling of the sunglasses was poor with only 53% making reference to UV transmission characteristics and only three pairs stating that they adhered to the New Zealand Sunglass Standard. Attention is drawn to the need to improve public awareness of the potential for eye injury from sunlight and to improve the standard of labelling of sunglasses.

Safety goggles should be worn by Australian workers.

Eye injuries in the workplace are a major cause of morbidity and disability, despite well publicised standards for industrial eye protection. A prospective survey of 51 patients presenting to a metropolitan emergency department with a work-related eye injury revealed that 32 injuries (63%), occurred to workers wearing some form of protective eye wear. However only seven (14%) were wearing eye protection that complied with the Australian Standard AS 1336 for occupational eye protection. Thirty-six patients (71%) had suffered previous eye injuries at work. Most injuries were caused by medium velocity particles generated by power tools, generally causing superficial corneal injury. We conclude that education to reduce the widespread misuse of safety glasses by tradespeople and trades assistants during tasks for which goggles are recommended could considerably reduce the incidence of occupational eye injuries.

The role of eye protection in work-related eye injuries.

PURPOSE/BACKGROUND: A recent survey of general hospitals by the Victorian Injury Surveillance System found that ocular trauma represented 15% of work-related injuries. As circumstances surrounding occupational eye injuries have been poorly documented previously, their associations to occupation, industry and work-safety practices, including safety eyewear use, need to be identified to develop appropriate preventive strategies for high-risk groups. DESIGN AND SETTING: From a prospective cross-sectional survey of all eye injuries treated at the Royal Victorian Eye and Ear Hospital, work-related cases were analysed for demographic, occupational and safety eye-wear information. Hospital-based data were supplemented by information from WorkCover Authorities and Labour Force statistics to derive incidence and cost estimates. RESULTS: There were 9390 eye injuries during the 18-month survey period; 42% (n=3923) of total and 29% (n=52) of penetrating ocular injuries occurred at work. The most frequently injured were metal, automotive and building trades workers grinding and drilling (41% of outpatients) and hammering (53% of penetrating eye injuries). Automotive workers had the highest frequency for penetrating injuries, and most were exposed to hammering and were also the least likely to wear safety eye-wear. CONCLUSION: Eye injuries are frequent (10% of work-related injuries) and highly preventable by the correct use of safety eye-wear, a cost-effective intervention that may result in cost savings of $59 million for work-type activities in the occupational and domestic settings in Australia each year.

Retinal damage by optical radiation. An alternative to current, ACGIH-inspired guidelines.

BACKGROUND: The ACGIH guidelines for protection against retinal damage by optical radiation are often difficult to apply due to their lack of transparency. The less known guidelines by the Netherlands Health Council (HCN), dating from 1978 and updated in 1993, might offer a way out in many cases. METHODS: A comparison is made of these guidelines, embedded in a short sketch of the history. They are illustrated by examples of applications. RESULTS: In most cases the HCN guidelines produce results that hardly deviate from those obtained with the ACGIH guidelines but in some cases the results diverge and in other cases HCN gives an answer where ACGIH seems to fall short. CONCLUSIONS: The HCN guidelines form a good alternative to those of ACGIH.

Evaluation of the performance of photochromic spectacle lenses in children and adolescents aged 10 to 15 years.

BACKGROUND: To compare the performance of clear and photochromic spectacle lenses in children and adolescents, with respect to visual acuity and satisfaction with day-to-day activities. METHODS: Fifty full-time spectacle wearers, aged 10 to 15 years, were randomly assigned to wear clear and Transitions photochromic spectacle lenses for two weeks each in a crossover fashion. Subjects were evaluated at screening, lens delivery and two weeks post-delivery. At each visit, distance and near visual acuity (VA, logMAR) were assessed and subjective questionnaires, using Likert scales, were administered. Parents/guardians also completed questionnaires at entry and exit from the study. RESULTS: There were no significant differences in VA between clear and photochromic lenses (p > 0.05) and no difficulties were encountered with completion of the questionnaires. Subjective evaluation of vision in bright sunlight and when playing sport was significantly better with photochromic compared to clear lenses (p < 0.05). There were no significant differences between lens designs in subjective performance indoors, such as in the classroom or when reading (p > 0.05). Forty-three subjects (88 per cent) chose to continue wearing photochromic lenses on conclusion of the trial. Thirty subjects (61 per cent) preferred photochromic over clear lenses due to reasons such as darkening in sunlight, better vision and less squinting in sunlight. Forty-three parents (88 per cent) rated the children's overall experience with photochromic lenses to be favourable or very favourable. CONCLUSION: Photochromic lenses can be successfully prescribed for children and adolescents aged 10 to 15 years. Clear and photochromic lenses were considered to be equivalent for indoor activities; however, photochromic lenses were significantly preferred over clear lenses for outdoor activities. Likert grading scales can be used effectively in questionnaires for children and adolescents and further development of questionnaires for use in clinical trials evaluating lens performance in children is warranted.

Should urologists wear spectacles for transurethral resection of the prostate?

Contamination of the eyes by irrigation fluid during transurethral resection (TUR) of the prostate was assessed by measuring droplet splashes on to spectacles worn by 2 surgeons. During 30 consecutive operations, droplet splash contamination occurred during every procedure. The number of splashes increased with time. The use of spectacles during TUR will reduce the risks of eye contamination from droplet splashes and therefore the possibility of transmission of the human immunodeficiency virus from infected patients.

Efficacy of corneal eye shields in protecting patients' eyes from laser irradiation.

BACKGROUND: The continuing development of new types and applications of lasers has appeared to surpass the development of specific eye protection for these lasers. There are a variety of eye shields on the market, but few are specifically designed for laser protection. OBJECTIVE: Our purpose was to test a variety of eye shields by two parameters, light transmission and temperature rise, and to determine from these measurements the most protective shield for patients. METHODS: We tested four plastic shields, one metal shield, and two sets of tanning goggles for temperature rise and light transmission when irradiated with a beam from a flashlamp-pumped, pulsed-dye laser. RESULTS: The temperature rise at the surface of the shield opposite the laser impacts was no more than 0.2 degree C in any case. White light was transmitted at significant levels through several of the shields, but yellow light transmittance was noted only through the green eye shield. CONCLUSION: Our measurements indicate that all except the green shield appeared safe from transmission of the 585-nm radiant energy. However, the optimal laser eye shield, in our opinion, would be a composite of several different shields' characteristics.
