BACKGROUND/PURPOSE To evaluate the relationship between refractive error and vision-related quality of life in 16-year-old students in Taiwan. METHODS A cross-sectional study was designed for 16-year junior-high-school students in Taiwan. Myopia was defined as a spherical refractive error (SRE) < -0.50 D, hyperopia as SRE > +1.0 D, and emmetropia as SRE -0.5-+1.0 D in the better eye. Vision-r...

purpose : to determine the prevalence of the uncorrected refractive errors in bojnourd students methods : in a cross-sectional study, the samples were selected proportionate to the population of the schools using stratified randomized cluster sampling. the target population was the primary and junior high school students of the city of bojnourd. visual acuity (va) (snellen chart) and cycloplegi...

the hospital, for whatever reason. • Human resources: both the number of people required (capacity) and the skills required (competence). • Quality: measuring and ensuring high quality clinical outcomes and patient satisfaction. • Operating efficiency: ensuring that scarce resources are optimally used. • Financial viability: pricing to ensure affordability, and putting in place revenue and cost...

BACKGROUND Refractive error is one of the leading causes of visual impairment in children. An analysis of risk factors for refractive error is required to reduce and prevent this common eye disease. OBJECTIVE To identify the risk factors associated with refractive errors in primary school children (6-12 year old) in Nakhon Pathom province. MATERIAL AND METHOD A population-based cross-sectio...

PURPOSE To study the relationships between the refractive power of the crystalline lens, overall refractive error of the eye, and degree of nuclear cataract. METHODS All phakic participants of the population-based Central India Eye and Medical Study with an age of 50+ years were included. Calculation of the refractive lens power was based on distance noncycloplegic refractive error, corneal r...

PURPOSE To determine the prevalence of distance refractive error among Aboriginal people attending eye clinics in remote South Australia. METHODS A clinic-based cross-sectional study was conducted that involved opportunistic sampling of Aboriginal people attending eye clinics in remote South Australia. There were 189 individuals who were invited to participate in the study all of whom underwe...

Previous investigations have reported considerable individual differences in the resting point of accommodation. Recent independent studies in Davis, Calif., and Cardiff, Wales, indicate that part of these variations are related to refractive errors. The average dioptric value of the resting point of accommodation is lowest for corrected myopes, highest for corrected hyperopes, and intermediate...

BACKGROUND Identifying and assessing retinal nerve fiber layer defects are important for diagnosing and managing glaucoma. We aimed to investigate the effect of refractive correction error on retinal nerve fiber layer (RNFL) thickness measured with Spectralis spectral-domain optical coherence tomography (SD-OCT). MATERIAL AND METHODS We included 68 participants: 32 healthy (normal) and 36 glauc...
