BACKGROUND The prevalence of refractive errors in school-age children in Morocco was assessed. METHODS A total of 545 children (300 boys and 245 girls, between 6 and 16 years of age) attending school were examined to assess their refractive errors in a field study in Morocco (North Africa). The examination included autorefraction under cycloplegia and(More)
The aim of this study is to examine the effects of aging as well as visual impairment on retinal-image quality and visual performance in drivers. We use a new visual test called Halo v1.0 software for quantifying the discrimination capacity, an important visual function for evaluating the visual disturbances perceived by the observer. The study included 55(More)
The prevalence of myopia and refractive errors is known to vary among different societies, and these differences may be attributed partly to differences in genetic background and partly to environmental factors, especially the amount of near work performed. The goal of this study was to determine the prevalence of refractive errors in school-age children in(More)
PURPOSE To evaluate the visual quality of two theoretical multifocal corneal models designed to correct presbyopia by corneal photoablation. METHODS Two theoretical multifocal corneal surfaces were analyzed by ray tracing: a central model (with a central zone for near vision and a peripheral zone for distance vision), and a peripheral model (with a(More)
Dermal exposure to pesticides is one of the main sanitary problems which greenhouses workers face. With the dual aims of establishing both the body part that receives the greatest exposure and the variable that has greatest influence on this exposure level, 22 pesticide application trials were performed. Trials were carried out in different greenhouse(More)
PURPOSE To assess epidemiological aspects of refractive errors in school-age children in Burkina Faso (west-central Africa). METHODS A total of 315 school children (ranging from 6 to 16 years of age and belonging to different ethnic groups) taken at random from two urban schools in eastern Burkina Faso were examined to assess their refractive error, which(More)
PURPOSE The aim of this work is to evaluate the epidemiological aspects of the refractive errors in school-aged children in Malabo (Island of Bioko), Equatorial Guinea (western-central Africa). METHODS A total of 425 schoolchildren (209 male subjects and 216 female subjects, aged between 6 and 16 years) were examined to evaluate their refraction errors in(More)
This study aimed to assess the differential impacts of lumbosacral orthosis (LO) wear in different sitting conditions through posturographic measurements. Twelve healthy subjects sat on a force platform with three variable stability levels (stable and on seesaws with a long and short radius, inferring slightly and highly unstable sitting, respectively) and(More)
Dear Editor, We have carefully read the article entitled “Quantitative evaluation of night vision and correlation of refractive and topographical parameters with glare after orthokeratology” by T Kojima et al. [1], and we agree that is a worthwhile study of night-vision disturbances that arise in certain surgical or nonsurgical techniques of(More)
The advances in new techniques for correcting presbyopia, such as a small aperture combined with monovision, require an in-depth study of binocular aspects. In this work, we have studied binocular visual performance of 12 subjects after inducing different degrees of anisocoria combined with two different add powers in the non-dominant eye. We have analysed(More)
