Myopia The Evidence for Environmental Factors Myopia has reached epidemic proportions in the youth of many Asian countries. Children also are becoming myopic earlier, and severe myopia is becoming more common.
Background: The objective of this study is to determine the relationship between publications and authors. In turn, different areas research on ocular complications myopia are also identified, most cited publication by citation networks determined. Methods: search for carried out in Web Science database using term “myopia OR nearsightedness AND retin* degenerat* detachment patholog* glaucoma ca...
Aims: To report success in the treatment of high myopia in children with LASIK. To report the visual results, complications and postoperative management of children with high myopia. Methods: Six children (seven eyes) with high myopia were included in this series. Preoperative and postoperative refraction, visual acuity, and pachymetry were compared. Results: Six children with high myopia rangi...
Myopia affects up to one-third of the population in the United States today. It is a leading cause of low vision in Asian countries secondary to the increased risk of retinal detachments and glaucoma. Genetics, as well as environmental factors and nearwork have been hypothesized to play a role in myopia development. Current techniques to control its progression target these etiologies. Methods ...
The adenosine antagonist 7-methylxanthine (7-mx) works against myopia in animal models. In a clinical trial, 68 myopic children (mean age 11.3 years) received either placebo or 7-mx tablets for 12 months. All participants subsequently received 7-mx for another 12 months, after which treatment was stopped. Axial length was measured with Zeiss IOL-Master and cycloplegic refraction with Nikon Reti...
PURPOSE Single nucleotide polymorphisms (SNPs) in the collagen type I (COL1A1) gene have been shown to be significantly associated with high myopia in a Japanese population. This present study was conducted to investigate whether COL1A1 is associated with high myopia in a Han Chinese population. METHODS High myopia is defined by a spherical equivalent of less than or equal to -6.00 diopter sp...
Myopia is amongst the most common refractive errors in the world. Both environmental and genetic factors are attributed to its causation, however all factors contributing to the development of myopia is yet to be found. Recent studies show presence of sex hormone receptor in the eyes. This has been shown to have a role in the development of various ocular pathologies. The second to fourth finge...
PURPOSE To establish whether features of environmental lighting in far northern latitudes might be associated with prevalence of myopia. METHODS Using both questionnaires and military medical examinations, this cross-sectional survey of Finnish conscripts assessed both light exposure and conventional risk factors for myopia. RESULTS While myopia was not associated with the month of birth, t...
PURPOSE To investigate whether myopia is becoming more common across Europe and explore whether increasing education levels, an important environmental risk factor for myopia, might explain any temporal trend. DESIGN Meta-analysis of population-based, cross-sectional studies from the European Eye Epidemiology (E(3)) Consortium. PARTICIPANTS The E(3) Consortium is a collaborative network of ...
BACKGROUND/AIMS A longitudinal study of premature infants was conducted to examine changes in refractive status and their relation with age and factors influencing the occurrence and degree of myopia. Identification of which of the various refractive factors play important parts in relation to myopia in premature infants was attempted. METHODS Under observation were 125 eyes in 65 patients wh...
