The Impact of Earplugs and Eye Masks on Sleep Quality in Surgical ICU Patients at Risk for Frequent Awakenings.

OBJECTIVES: Sleep disturbances may contribute to the development of delirium, prolonged ICU stay, and increased mortality. There is conflicting data on the effectiveness of earplugs and eye masks for sleep promotion in the ICU. This study evaluates the impact of earplugs and eye masks on sleep quality in postoperative surgical ICU patients at risk for frequent awakenings. DESIGN: Prospective randomized controlled trial. SETTING: Surgical ICU within the University of Texas Southwestern Medical Center. PATIENTS: Adult, female patients admitted to the surgical ICU requiring hourly postoperative assessments following breast free flap surgery between February 2018 and October 2019. INTERVENTIONS: Patients were randomized into an intervention group or a control group. The intervention group received earplugs and eye masks in addition to standard postoperative care, whereas the control group received standard postoperative care. MEASUREMENTS AND MAIN RESULTS: The primary outcome was overall sleep quality assessed via the Richards-Campbell Sleep Questionnaire. Secondary outcomes of patient satisfaction and rates of ICU delirium were assessed with a modified version of the Family Satisfaction in the ICU survey and the Confusion Assessment Method for the ICU. After a planned interim analysis, the study was stopped early because prespecified criteria for significance were attained. Compared with the control group's average Richards-Campbell Sleep Questionnaire total score of 47.3 (95% CI, 40.8-53.8), the intervention group's average Richards-Campbell Sleep Questionnaire total score was significantly higher at 64.5 (95% CI, 58.3-70.7; p = 0.0007). There were no significant between-group differences for Confusion Assessment Method for the ICU scores or modified Family Satisfaction in the ICU survey scores. CONCLUSIONS: These results suggest that earplugs and eye masks are effective in improving sleep quality in ICU patients undergoing frequent assessments. The results strengthen the evidence for nonpharmacologic sleep-promoting adjuncts in the ICU.

Prevalence of Lens Opacity in Interventional Cardiologists and Professional Working in the Hemodynamics in Brazil / Prevalência de Opacidades do Cristalino em Cardiologistas Intervencionistas e Profissionais Atuantes na Área de Hemodinâmica no Brasil

Abstract Background: Posterior subcapsular cataract is a tissue reaction commonly found among professionals exposed to ionizing radiation. Objective: To assess the prevalence of cataract in professionals working in hemodynamics in Brazil. Methods: Professionals exposed to ionizing radiation (group 1, G1) underwent slit lamp examination with a biomicroscope for lens examination and compared with non-exposed subjects (group 2, G2). Ophthalmologic findings were described and classified by opacity degree and localization using the Lens Opacities Classification System III. Both groups answered a questionnaire on work and health conditions to investigate the presence of risk factors for cataract. The level of significance was set at 5% (p < 0.05). Results: A total of 112 volunteers of G1, mean age of 44.95 (±10.23) years, and 88 volunteers of G2, mean age of 48.07 (±12.18) years were evaluated; 75.2% of G1 and 85.2% of G2 were physicians. Statistical analysis between G1 and G2 showed a prevalence of posterior subcapsular cataract of 13% and 2% in G1 and G2, respectively (0.0081). Considering physicians only, 38% of G1 and 15% of G2 had cataract, with the prevalence of posterior subcapsular cataract of 13% and 3%, respectively (p = 0.0176). Among non-physicians, no difference was found in the prevalence of cataract (by types). Conclusions: Cataract was more prevalent in professionals exposed to ionizing radiation, with posterior subcapsular cataract the most frequent finding.

Resumo Fundamento: A catarata subcapsular posterior é uma reação tecidual encontrada com frequência nos profissionais expostos à radiação ionizante. Objetivo: Avaliar a prevalência de catarata nos profissionais que atuam na área de hemodinâmica no Brasil. Métodos: Profissionais expostos à radiação ionizante (grupo 1, G1) foram submetidos ao exame biomicroscópico com lâmpada de fenda para avaliação do cristalino, e comparados aos não expostos (grupo 2, G2). Os achados foram descritos e classificados quanto ao grau de opacidade e localização por meio do Lens opacities classification system III. Ambos os grupos responderam questionário sobre condições de trabalho e de saúde para afastar fatores de risco para catarata, e foram comparados quanto aos achados. Foi utilizado um nível de significância de 5% (p < 0,05). Resultados: Foram avaliados 112 voluntários (G1) com média de idade 44,95 (±10,23) anos e 88 voluntários (G2) com média de 48,07 (±12,18) anos. Desses, 75,2% (G1) e 85,2% (G2) eram médicos. A análise estatística entre os grupos G1 e G2 mostrou uma prevalência da catarata no grupo G1 de 33% comparada ao G2 de 16% (p = 0,0058), sendo a catarata subcapsular posterior presente em 13% no G1 e 2% no G2 (p = 0,0081). Considerando apenas os médicos, 38% no G1 e 15% no G2 (p = 0,0011) apresentaram catarata, sendo a subcapsular posterior 13% e 3% (p = 0,0176), respectivamente. No grupo dos profissionais não médicos, não houve diferença estatisticamente significativa na prevalência dos achados oftalmológicos. Conclusões: A catarata esteve mais presente no grupo de profissionais expostos à radiação ionizante, sendo que a catarata subcapsular posterior foi o dano tecidual mais encontrado.

Behaviors of active sunbeds users and their knowledge on the potential health risks; results of cross-sectional study in Poland.

BACKGROUND: Current literature review indicates that there is an increase in risk of skin melanoma due to the use of sunbeds. AIMS: To assess behaviors and opinions about health risk related to tanning. METHODS: From March 2012 to June of the same year, nonrepresentative cross-sectional study was conducted online concerning knowledge and behaviors during tanning. Data from 4919 people (80% of women, median age 25 years [IQR: 20-36]) were analyzed statistically with R software (level of significance at α = .05). We used the authors "active users of sunbeds" (AUS) criterion, denoting person using it ≥2 times per year with an average sessions lasting ≥5 minutes (cutoff values above 1 quartile). The reference was those not meeting above criteria. RESULTS: A total of 926 persons (18.8%) stated that they use sunbeds, while 680 (13.8%) met the criterion of AUS. Within the AUS group, the median number of visits in the tanning beds rooms was 10 (IQR: 5-15) per year, with single session lasting 9 (IQR: 7-10) minutes. The majority (83.5%) of AUS tanned naked indoors, with only 47.4% to have used safety glasses. These individuals were significantly more likely to be women, better educated, and were considered outdoor tanners. AUS were less aware of the risks associated with sunburns, with equal use of sunscreen and reapplication more frequently (as non-AUS). CONCLUSIONS: The level of knowledge in the field of prevention of melanoma was similar in both groups; however, AUS group more frequently took risky behaviors related to sun exposure.

EVALUATION OF OCCUPATIONAL RADIATION DOSE IN TRANSCATHETER AORTIC VALVE IMPLANTATION.

Occupational doses during fluoroscopy in interventional procedures vary largely (Kim et al. (Occupational radiation doses to operators performing cardiac catheterization procedures. Health Phys. 2008;94:211-227)). In transcatheter aortic valve implantation, the operators' positions and use of radiation shielding are particularly related to the entry choice on the patient's heart. This study evaluates how occupational doses depend on operator positioning during transfemoral and transaortal access. Occupational dosimetric readings were collected with electronic dosemeters on two cardiothoracic surgeons and one cardiologist during 31 procedures. The findings were significantly higher body doses and eye lens doses to the surgeons during transaortal access compared to transfemoral access. The median equivalent eye lens dose per procedure received by the cardiologists was 0.05-0.06 mSv; hence, the cardiologists should wear protective eye wear to prevent reaching the proposed annual dose limit of 20 mSv to the eye lens. Surgeons ought to use protective eye wear as well, and should only perform a restricted number of transcatheter aortic valve implantations with transaortal access annually.

Eye Protection: Survey of Dermatologists and Office Staff.

BACKGROUND: Splash injuries to mucosal membranes during procedures have been well documented in dermatology and carry a potential risk of blood-borne virus transmission. The risk to the ocular mucosa can be minimized with proper eye protection. OBJECTIVE: To examine the prevalence of wearing eye protection during dermatologic procedures by physicians, trainees, and office staff in dermatology. METHODS: A Cross-sectional observational study of US dermatologists, residents, nurses, and medical assistants was performed regarding eye protection during dermatologic procedures. RESULTS: The rates of wearing eye protection in every dermatologic procedure are as follows: dermatologists 42.3%, residents/fellows 39.6%, and nurses/medical assistants 25%. Ninety-eight percent of respondents thought blood-borne illnesses could be transmitted by splash injury. The rates of having splash injury during your career are as follows: dermatologists 73.1%, residents/fellows 16.7%, and nurses/medical assistants 50%. The rates of having a splash injury within the last year are as follows: dermatologists 11.5%, residents/fellows 8.3%, and nurses/medical assistants 35.7%. CONCLUSION: The use of eye protection is an important component of the personal protective equipment to help prevent transmission of blood-borne illnesses. Dermatologists and staff should strive to increase awareness and the use of face masks with eye shields or face mask with separate eye protection in every dermatologic procedure.

The prevalence of occupational health-related problems in dentistry: A review of the literature.

The study was conducted to report on the scope and prevalence of occupational health related-problems experienced by dentists, dental therapists, and oral hygienists in their practice of dentistry. BACKGROUND: Professional practice and dental training have many risk factors, and the dental team should be able to recognize these factors to protect themselves. The prevalence of conditions related to the musculoskeletal system, stress, percutaneous injuries, ears, and eyes are of concern. The dental team should also not forget hepatitis B, hepatitis C, and HIV as risks in practice. Dental practitioners should protect themselves by self-recognizing risk factors and by maintaining proper working conditions. METHODS: The study targeted all empirical research, case studies, and systematic literature reviews written in English. All articles selected were subjected to a data analysis process. Data were captured on an Excel spreadsheet and reported in a comprehensive table. RESULTS: The literature addressing occupational health among dental practitioners included mainly cross-sectional studies and review papers (2001-2016). Forty-nine studies were included in the review. Musculoskeletal disorders remain the most researched occupational health-related problems in dentistry. Eye protection compliance was low among practitioners. Percutaneous injuries especially among young dentists and students were still a concern. CONCLUSION: Occupational health-related problems are still prevalent in current dentistry practice, despite changes in equipment and surgery design. The reported prevalence of occupational related-health problems and other findings of investigative studies highlight the need for continuous professional education and a need to improve clinical practice aspects of dentistry curricula.

Retinal Detachment Associated With Basketball-Related Eye Trauma.

PURPOSE: Basketball is a popular sport involving significant body contact, which may frequently result in ocular trauma. The aim of this study was to evaluate the characteristics and visual outcomes of retinal detachment associated with basketball-related injury. DESIGN: Retrospective, interventional case series. METHODS: We reviewed the course of patients who sustained traumatic retinal detachment from basketball-related ocular trauma between 2003 and 2015. RESULTS: Thirteen patients were evaluated for basketball-related traumatic retinal detachment. Twelve (92%) were male and 1 (8%) female, with an average age of 18.2 years. The majority (9 of 13, 70%) of patients had moderate-to-high myopia, and none were using protective eyewear when they sustained the eye trauma. Rhegmatogenous retinal detachment was observed in all eyes. The preoperative mean visual acuity was 20/625 (range, hand motions to 20/20). Initial surgery using scleral buckling alone was performed in most (8 of 13, 62%) of the patients. Retinal reattachment was achieved in 10 (76%) eyes after the first operation and in 12 (92%) at the end of the intervention. The mean follow-up was 3.9 years (range, 4 months to 12 years). The visual acuity during last follow-up was 20/231 (range, light perception to 20/20). In the multivariable analysis, initial visual acuity was an independent factor affecting the final visual outcome (P = .006). CONCLUSION: Retinal detachment associated with basketball-related injury may cause severe visual loss. In the current study, all retinal detachments were of rhegmatogenous type and commonly occurred in young individuals with myopia. Initial visual acuity was associated with the prognosis. Risk awareness for early detection and intervention are important in these traumas.

New organ-based tube current modulation method to reduce the radiation dose during computed tomography of the head: evaluation of image quality and radiation dose to the eyes in the phantom study.

A new organ-based tube current modulation (NOB-TCM) method was designed with the intent to decrease tube current by 30% over a prescribed 90° radial arc across the anterior aspect of the radiosensitive organ, without increasing tube current in the remaining radial arc. We compared a reference scan and five other dose-reducing methods with regard to effects on dose, practicality, and image quality to determine the most effective method for the reduction of the radiation dose to the eyes during CT examinations of the head. We compared the radiation doses to the eyes and physical image quality in different regions of interest for TCM and shielding scans. Three types of TCM scans were performed: longitudinal TCM, angular TCM, and NOB-TCM. A bismuth sheet and lead goggles were each applied for the shielding scan. Relative to the reference scan, the dose to the eye was reduced to 25.88% with NOB-TCM, 44.53% with lead goggles, and 36.91% with a bismuth shield. Relative to the reference scan, the mean signal-to-noise ratio (SNR) was decreased to 8.02% with NOB-TCM, 28.36% with lead goggles, and 32.95% with the bismuth shield. The SNR of the anterior region of interest was decreased to 11.89% with NOB-TCM and 87.89% with the bismuth shield. The average figure of merit was increased by 11.7% with longitudinal TCM and 13.39% with NOB-TCM, compared with the reference scan. NOB-TCM is a superior solution for head CT, including the orbital area, due to the reduction in radiation exposure without significant loss in image quality.

Attitudes and Behaviors Related to Sun-Safety in College Students.

The purpose of this study was to determine the level of sun safe behaviors, as well as to measure knowledge and attitudes toward being tan in a sample of college students. The sample was comprised of 315 college students attending a personal health course. During Fall of 2016, a survey was distributed to assess knowledge, attitudes, and behaviors of university students regarding skin cancer related behaviors. Students with a friend or family member with skin cancer more often reported thinking that they were at risk for developing skin cancer (48.6 vs. 21.2%, p < 0.001). Despite this opinion, they more often sunbathed (p = 0.008) and had a sunburn (p < 0.001) in the past year. Being in a health-related major did not significantly impact attitudes or behaviors. Future studies can focus further on raising awareness about skin cancer, specifically in college aged populations.

Sun-protection practices among undergraduates at an Australian University.

BACKGROUND/OBJECTIVES: To assess the sun-protection practices of undergraduates at the Australian National University. METHODS: We sent emails with links to the questionnaire on the use of five sun-protection practices in the last fortnight of the summer to 3341 randomly selected students aged 18-24 years in this cross-sectional study. The response rate was 19% and 507 students met the inclusion criteria. RESULTS: The sample consisted of 338 female and 169 male students with a mean age of 20.5 years (SD ± 1.9). Any method of sun protection was used always or often by 32% of respondents. The commonest method used was shade (58%) while the least common was wearing a hat (8%). Domestic students (44%) used sunglasses more than the international students (23%, P < 0.05) and female students used sunscreen (48%) and sunglasses (37%) more than male students (33% and 23% respectively) (P < 0.05). In the 22-24-year-old age group non-medical students (54%) used sunglasses more than the medical students (36%, P < 0.05). CONCLUSIONS: Only a third of the sample practiced any method of sun protection and there were significant differences in the practices between subgroups, suggesting they were at an increased risk of sun damage.

Compliance With Protective Lens Wear in Anophthalmic Patients.

PURPOSE: To evaluate the frequency of protective lens wear by anophthalmic patients and identify factors that influence compliance. METHODS: An IRB approved descriptive retrospective chart review of patients undergoing surgery with the senior author (PLC) with an anophthalmic orbit and one remaining sighted eye. Results were tabulated and analyzed using age, indication for procedure, duration of visual symptoms, safety glasses wear, number of postoperative visits, and evidence of new trauma to the remaining eye. All patients underwent counseling on the importance of protective lens wear preoperatively and each subsequent visit. RESULTS: Etiologies for loss of the eye in the 132 study patients included trauma (33.3%), blind painful eye (33.3%), congenital disorders (14.4%), adult-onset malignancy (14.4%), and retinoblastoma (4.5%). At the final visit, protective lenses were worn in the following patterns: full-time (55.3%), frequently (11.4%), occasional (6%), and never (28.8%). The regular use of protective eyewear at last visit was more common in patients wearing glasses at presentation (79.7%), than in those who did not (32.9%; p ≤ 0.001). Increased number of office encounters correlated with more frequent use of protective eyewear (p ≤ 0.01). Patient age (p = 0.95), indication for surgery (p = 0.97), and duration of visual loss (p = 0.85) were not predictive of safety glasses wear. Three patients had evidence of subsequent ocular trauma to the remaining eye, with 2 having resultant decrease in acuity; none of these 3 patients wore safety glasses full-time. CONCLUSIONS: A significant number of anopthalmic patients were not wearing protective lenses at presentation. Overall compliance was poor; but repeated education on the importance of safety glasses appears to improve compliance. Educating referring providers and primary care physicians about the importance of early and repeated counseling is vital to increasing compliance.

[A New Way to Look Up. Solar Retinopathy Risks and Methods of Prevention Prior to the 2015 Solar Eclipse]. / Risiken und präventive Maßnahmen angesichts der Sonnenfinsternis März 2015.

A solar eclipse is an impressive natural phenomenon that was last experienced in Europe in 2006. Last year, on March 20th 2015, a solar eclipse was visible in much of Europe. Solar retinopathy is a recognised potentially sight threatening condition that has been associated with direct or unprotected sun gazing. Public education has been shown to improve behaviour and attitudes that could influence the development of solar retinopathy during an eclipse. We have performed a study through newspapers prior to the 2015 solar eclipse in different European countries, in order to determine the level of public health awareness and attitudes to protection. Methods: 31 online editions of national newspapers were reviewed from six countries where the eclipse was most visible. Solar retinopathy, potential warnings, safe methods of viewing an eclipse and assessment of use and dangers of modern technologies were assessed. Results: All 25 newspapers examined mentioned the solar eclipse and risk to eyesight. Safe methods for viewing the eclipse were discussed in all newspapers. Eclipse eyeglasses were mentioned in 29 of the 31 newspapers reviewed. Children were identified as a high-risk group but advice for children viewing the eclipse varied between countries. Conclusion: Since the solar eclipse of 2006, there has been an increase in the level of education available in the media. Although the safe methods for viewing an eclipse have not changed in recent years, emerging technologies, such as camera phones and the "selfie" trend, have potentially increased the risk of eclipse-associated retinopathy.

Trends in sun-protection behaviour in Australian adults 2007-2012.

BACKGROUND: Almost all skin cancers are the result of overexposure to UV radiation and could be prevented by adhering to a number of simple behavioural guidelines to minimise exposure to the sun. The present study examined trends in sun-protection behaviour among adults living in Western Australia, a region with high levels of UV radiation. METHODS: During five summers from 2008 to 2012, 2076 Western Australian adults participated in annual, cross-sectional telephone surveys that assessed how often they engaged in a range of sun-protection behaviour (seeking shade, staying inside and wearing a hat, protective clothing, sunscreen or sunglasses). RESULTS: Apart from an increase in sunscreen use and a consistently high use of sunglasses, most sun-protection behaviour remained stable at moderate levels during the 5-year period. Seeking shade, staying inside and wearing a hat were all practised at levels ranging between 'sometimes' and 'usually' on sunny days in summer during peak UV hours, with little to no variability across the survey years. Wearing protective clothing was the least frequent behaviour across all survey years and was significantly lower in the most recent survey year relative to baseline. CONCLUSIONS: Further efforts are required to encourage greater enactment of sun-protection behaviour, especially on the use of protective clothing and seeking shade during periods of high UV radiation.

COMPREHENSIVE REVIEW OF GOLF-RELATED OCULAR INJURIES.

PURPOSE: The authors aimed to analyze the causes and outcomes of golf-related ocular injuries in this retrospective meta-analysis, literature review, and original case series. METHODS: Forty-one articles identified by PubMed search resulted in 11 included studies yielding 102 subjects. Included articles described all ocular golf injuries that presented to an institution during a determined period. Eight factors were analyzed: age, sex, location and mechanism of injury, protective eyewear use, resulting open-globe injury, resulting enucleation, and visual acuity changes. RESULTS: No subjects wore adequate protective eyewear. Significantly more subjects were injured by golf balls (72%) than golf clubs (27%) or foreign body (1%) (P < 0.0001). The ratio of golf ball to club injuries was significantly higher in adults (92%) than in children (23%) (P < 0.0001). Forty-seven of 93 (51%) injuries resulted in an open globe, whereas 27/82 (33%) injuries resulted in enucleation. The mean ± SD logMAR visual acuity improved by -0.641 ± 0.745 after treatment (>6 lines of improvement; P = 0.0001). CONCLUSION: Reported ocular golf injuries occur less frequently than other ocular sports injuries, but may result in devastating outcomes. Supervision of children using golf equipment should be encouraged.

Outdoor workers and sun protection strategies: two case study examples in Queensland, Australia.

INTRODUCTION: Outdoor workers are at risk of developing skin cancer because they are exposed to high levels of harmful ultraviolet radiation. The Outdoor Workers Sun Protection Project investigated sun protection strategies for high risk outdoor workers in rural and regional Australia. METHODS: Fourteen workplaces (recruitment rate 37%) across four industries in rural and regional Queensland, Australia were recruited to the OWSPP. In 2011-2012, data were collected using pre- and post-intervention interviews and discussion groups. This article presents two workplaces as case study examples. RESULTS: The flat organisational structure of workplace 1 supported the implementation of the Sun Safety Action Plan (SSAP), whilst the hierarchical organisational nature of workplace 2 delayed implementation of the SSAP. Neither workplace had an existing sun protection policy but both workplaces adopted one. An effect related to the researchers' presence was seen in workplace 1 and to a lesser degree in workplace 2. Overt reciprocity was seen between management and workers in workplace 1 but this was not so evident in workplace 2. In both workplaces, the role of the workplace champion was pivotal to SSAP progression. CONCLUSIONS: These two case studies highlight a number of contextually bound workplace characteristics related to sun safety. These issues are (1) the structure of workplace, (2) policy, (3) an effect related to the researchers' presence, (4) the workplace champion and (5) reciprocity. There are several recommendations from this article. Workplace health promotion strategies for sun safety need to be contextualised to individual workplaces to take advantage of the strengths of the workplace and to build capacity.

Occupational Ocular UV Exposure in Civilian Aircrew.

INTRODUCTION: Ultraviolet radiation (UVR) increases with altitude; however, there are a number of other factors which may influence ocular exposure during flight. The aim of this study was to assess ocular UVR exposure of pilots in airline and off-shore helicopter operations on different aircraft types and to compare with exposure in a typical office environment. METHOD: In-flight data were captured on equipment including a CCD array spectroradiometer on five return sector European airline flights and one transatlantic flight from London Gatwick in addition to four helicopter flights from Aberdeen Dyce airport. Further data were collected in an office environment from three workstations during summer and winter months. RESULTS: A wide variation in ocular UVA dose was found during flights. The main factor influencing exposure was the UVR transmission of the windshield, which fell into two distinct profile types. In an aircraft with good UVA blocking properties, ocular exposure was found to be equivalent to office exposure and did not exceed international guideline limits regardless of external conditions or flight time. Most aircraft assessed had poor UVA blocking windshields which resulted in an ocular exposure to the unprotected eye in excess of international guideline limits (up to between 4.5 to 6.5 times greater during one flight). No significant UVB dose was found. DISCUSSION: Pilots should be warned of the potential high UVA exposure during flight and advised on the use of sunglasses. A windshield labeling system would allow the pilot to tailor their eye protection practices to that particular aircraft.

Solar Eye Protection Practices of Civilian Aircrew.

INTRODUCTION: There is good evidence that long term exposure to ultraviolet (UV) radiation increases the risk of cataracts. The 'blue light hazard' is considered a risk factor for retinal changes similar to those seen in macular degeneration. Previous studies ascertaining the prevalence of radiation related ocular disease in pilot cohorts have not considered use of solar eye protection. The aim of this study was to explore pilot use of sunglasses and other solar eye protection habits and to gain insight into the difficulties encountered managing sunlight on the flight deck. Additionally, the prevalence of radiation related ocular pathology in the study group was calculated. METHODS: A web based questionnaire was developed and administered to a large population of current UK professional pilots. RESULTS: There were 2917 respondents who completed the questionnaire, demonstrating a wide range of sunglass use during flight. A number of barriers to sunglass use were identified, the most prevalent being the requirement for corrective lenses to be used. Pilots most commonly increase sunglass use due to ocular health concerns. A high level of dissatisfaction with standard aircraft sun protection systems was reported. Long haul airline pilots were the highest users of nonstandard sunlight blocking strategies. No correlation between reported pathology and flying experience was found. DISCUSSION: The use of sunglasses during flight is complex; however, a number of practical recommendations can be made to increase the success for those pilots who wish to use sunglasses more. Aircraft manufacturers should consider how greater control of cockpit sunlight levels can be achieved.

Assessment of Office-Based Practice Patterns on Protective Eyewear Counseling for Patients With Monocular Vision.

PURPOSE: To investigate the practice patterns of office-based counseling on the importance of protective eyeglasses in monocular patients and to offer our counseling recommendations. METHODS: In this cross-sectional study, data were collected in the form of surveys. Surveys were administered at an oculoplastic ophthalmology clinic in Michigan. Inclusion criteria included adults with vision of 20/400 or worse in only 1 eye. Survey questions were focused on whether patients with monocular vision recall being previously counseled by their primary ophthalmologist about wearing eye protection. RESULTS: A total of 60 surveys were completed. The average age was 62.2 years old (range: 23-90 years old). Of the completed surveys, 56.7% (34/60) did not recall receiving education about wearing protective glasses over their better seeing eye, while 35.0% (21/60) recalled having received education from their referring ophthalmologist about eye protection, and 8.3% (5/60) were uncertain about receiving eye protection counseling. Twenty (33.3%) patients reported the reason for decreased vision. Of those, 35% (7/20) of patients reported monocular vision resulting from trauma, while 65% (13/20) reported vision loss due to other reasons. There was no significant difference in recall of receiving counseling about the importance of eye protection between the 2 groups (p = 0.74). CONCLUSIONS: The results of this study highlight the current counseling short-comings, as more than half (56.7%) of patients surveyed did not recall being counseled on the importance of protecting their better seeing-eye, or ways of doing so. More counseling on protective eyewear needs to be incorporated into the preferred practice pattern for care of patients with monocular visual impairment because these patients are vulnerable to the devastating consequences of complete blindness as a result of an injury to their functioning eye.

Conjunctival UV autofluorescence--prevalence and risk factors.

PURPOSE: Autofluorescence of ultraviolet (UV) light has been shown to occur in localised areas of the bulbar conjunctiva, which map to active cellular changes due to UV and environmental exposure. This study examined the presence of conjunctival UV autofluorescence in eye care practitioners (ECPs) across Europe and the Middle East and its associated risk factors. METHOD: Images were captured of 307 ECPs right eyes in the Czech Republic, Germany, Greece, Kuwait, Netherlands, Sweden, Switzerland, United Arab Emirates and the United Kingdom using a Nikon D100 camera and dual flash units through UV filters. UV autofluorescence was outlined using ImageJ software and the nasal and temporal area quantified. Subjects were required to complete a questionnaire on their demographics and lifestyle including general exposure to UV and refractive correction. RESULTS: Average age of the subjects was 38.5±12.2 years (range 19-68) and 39.7% were male. Sixty-two percent of eyes had some conjunctival damage as indicated by UV autofluorescence. The average area of damage was higher (p=0.005) nasally (2.95±4.52mm(2)) than temporally (2.19±4.17mm(2)). The area of UV damage was not related to age (r=0.03, p=0.674), gender (p=0.194), self-reported sun exposure lifestyle (p>0.05), geographical location (p=0174), sunglasses use (p>0.05) or UV-blocking contact lens use (p>0.05), although it was higher in those wearing contact lenses with minimal UV-blocking and no spectacles (p=0.015). The area of UV damage was also less nasally in those who wore contact lenses and spectacles compared to those with no refractive correction use (p=0.011 nasal; p=0.958 temporal). CONCLUSION: UV conjunctival damage is common even in Europe, Kuwait and UAE, and among ECPs. The area of damage appears to be linked with the use of refractive correction, with greater damage nasally than temporally which may be explained by the peripheral light focusing effect.

The use of rigid eye shields (Fox shields) at the point of injury for ocular trauma in Afghanistan.

BACKGROUND: Unlike hemorrhagic injuries in which direct pressure is indicated, any pressure placed on the eye after penetrating trauma can significantly worsen the injury by expulsing intraocular contents. The accepted first response measure for obvious or suspected penetrating ocular injury is placement of a rigid shield that vaults the eye so as to prevent accidental iatrogenic aggravation during transport to the ophthalmologist. Patching and placing intervening gauze between the shield and the eye are both contraindicated. Anecdotally, compliance with these recommendations is poor in the military and civilian communities alike; however, published studies documenting compliance are uniformly lacking. This study was undertaken to provide such an evaluation. METHODS: In this retrospective observational study, the Department of Defense Trauma Registry was reviewed to identify eye injuries in Afghanistan from 2010 to 2012 and to examine compliance with eye shield recommendations. One hundred fifty-seven records of eye casualties were identified and categorized according to diagnostic codes, noting use of a shield. A subset of 30 records was further analyzed for compliance with other core treatment measures specified by the operant Clinical Practice Guideline. Because comparative studies do not exist, simple statistical analysis was performed. RESULTS: Overall, 39% of eye injuries received a shield at the point of injury (61% failure), ranging from 0% to 50% between diagnostic subgroups. Subset analysis revealed that only 4.2% of injuries were successfully mitigated at the point of injury (95.8% failure). CONCLUSION: In one of the few studies documenting the use of eye shields after ocular trauma, anecdotal reports of poor, inadequate, or incorrect compliance with basic recommendations were substantiated. Several factors may account for these findings. Corrective efforts should include enhanced educational emphasis and increased shield availability. LEVEL OF EVIDENCE: Epidemiologic study, level IV. Therapeutic study, level IV.
