Personnel monitoring data reported in the literature at selected monitoring sites for personnel working in fluoroscopic X-ray facilities are analyzed. The results are used to attempt to more realistically estimate the potential organ doses for X-ray personnel wearing protective devices such as lead aprons and protective eyeglasses when these personnel wear only one dosimeter positioned outside ...

PURPOSE To assess vision health disparities in the United States by race/ethnicity, education, and economic status. DESIGN Cross-sectional, nationally representative samples. METHODS We used national survey data from the National Health and Nutrition Examination Survey (NHANES) and the National Health Interview Survey (NHIS). Main outcome measures included, from NHANES, age-related eye dise...

Acknowledgements First of all, I would like to thank all IRIS Lab members. I would like to thank my advisor, Dr. Mongi Abidi. His willingness to support my work and his guidance throughout my studies has allowed me to develop my skills as a face recognition researcher within a supportive team environment. Abstract This paper describes how fusion of visual and thermal face recognition can increa...

BACKGROUND We sought to elicit preference weights from parents for health states corresponding to children with various levels of severity of atopic dermatitis. We also evaluated the hypothesis that parents with children who had been diagnosed with atopic dermatitis would assign different preferences to the health state scenarios compared with parents who did not have a child with atopic dermat...

INTRODUCTION Patients with end-stage renal disease who receive hemodialysis are prone to visual disturbances. The aim of this study was to evaluate the effects of metabolic changes on visual parameters during hemodialysis sessions. MATERIALS AND METHODS Demographic information including history of underlying diseases, wearing eyeglasses, any ocular diseases or surgeries, and hemodialysis dura...

PURPOSE To evaluate factors that can influence the prevalence of amblyopia in children with anisometropia. METHODS We retrospectively reviewed the records of 63 children 2 to 13 years of age who had anisometropic amblyopia with a difference in the refractive errors between the eyes of at least two diopters (D). The type of anisometropia (myopia, hyperopia, and astigmatism), degree of anisomet...

About 10% of primary school students in developing countries have poor vision, yet in virtually all of these countries very few children wear glasses. There has been almost no research on the impact of poor vision on school performance in developing countries, and simple OLS estimates are likely to be biased because students who study more often are likely to develop poor vision faster. This pa...

Hyperopia is a common refractive error that is usually corrected with eyeglasses or contact lenses. Following the fast advancement in refractive surgery and technology, eyeglasses or contact lenses were no longer the single treatment option in refractive errors. Today, extraction of transparent lens and intraocular lens implantation, phacic intraocular lens applications and corneal surgeries ar...

BACKGROUND During perimetric testing it is well known to wear spectacles. But less is known about to what extent refractive errors affect the response time performing computer-based visual tasks. METHODS Patients with visual field defects (VFD) (n = 6) and normal control subjects (n = 6) performed computer-based high resolution perimetry (HRP) with and without the use of spectacles. We record...

OBJECTIVE To examine racial and ethnic differences in unmet need for vision care among children with special health care needs. METHODS Cross-sectional data from the National Survey of Children with Special Health Care Needs were analyzed. The analytic sample was 14,070 children with special health care needs who needed eyeglasses or vision care in the previous year. Children who did not rece...
