Do reduced visual acuity and refractive error affect classroom performance?
Clinical and experimental optometry, 2020The role of visual acuity and refractive errors in the academic performance of children is controversial due to the variable quality of the research in this area and the mixed findings reported.

Refractive errors and schizophrenia
Schizophrenia Research, 2009Refractive errors (myopia, hyperopia and amblyopia), like schizophrenia, have a strong genetic cause, and dopamine has been proposed as a potential mediator in their pathophysiology. The present study explored the association between refractive errors in adolescence and schizophrenia, and the potential familiality of this association.The Israeli Draft ...

Management of refractive errors
BMJ, 2010Uncorrected refractive error accounts for half of the global burden of avoidable vision impairment and nearly a third of the global burden of avoidable blindness.1 2 Globally, 153 million people have visual impairment or are blind due to uncorrected refractive error and the majority live in low income countries.1 Additionally, 410 million people have ...

ABSTRACT.Purpose: To study the association between refractive error, glaucoma damage and IOP in a large population.Methods: We examined 32,918 citizens of the city of Malmö, Sweden, 57–79 years of age, searching for individuals with undetected glaucoma. Refraction was measured with autorefractors.

Refraction and refractive errors in an elderly population
Ophthalmic and Physiological Optics, 1988The data for this paper were collected during a two‐year study of the elderly in the market town of Melton Mowbray. The randomly selected subjects, aged 76 years of age and older, were found to be on average + 1.33 D hypermetropic and the average cylinder power was 0.82 D.

Optical correction of refractive errors in infants and young children is indicated when the refractive errors are sufficiently large to cause unilateral or bilateral amblyopia, if they are impairing the child's ability to function normally, or if the child has accommodative strabismus.

Distribution of refractive errors in Spain
Documenta Ophthalmologica, 2000The aim of this work was to characterise the refractive state of a Spanish population. Special attention to myopia prevalence was carried out. At this stage 7621 subjects, 3692 males and 3929 females, between 3 and 93 years were examined by means of static retinoscopy and subjective refraction.

Refractive Errors in Twin Studies
Twin Research and Human Genetics, 2006AbstractIt is estimated that 1.6 billion people worldwide have myopia, a refractive error, and this number is expected to increase to approximately 2.5 billion by the year 2020. It is now well established that both the environment and genetics play a role in the development of myopia.

Publisher Summary A common cause of blurred vision is refractive error. This is a physiological condition where the refracting system of the eye fails to focus objects sharply on the retina. It is usually corrected with glasses. Myopia is an optical condition where distant objects are focused in front of the retina so that vision for distance is ...
