It appears that other factors such as computer games and mother-level education affect this disease, and it is estimated that by 4205 people will affect 4,758 million people worldwide. This is indicated by this study applied in twins.
Million is explained by consensus, through hereditary factors.
Being born in the summer and hours devoted to computer games is associated with increased risk of developing short or close myopia in childhood, points out the study of twins published in the digital edition & # 39;British Journal of Ophthalmology". But fertility treatments can be protective, the results show. (Read: Most Obstetric Illness in Colombia)
Millioquia is defined as a refractive error, meaning that the eye can not properly focus the light, which causes close objects to be clear, but distant objects seem unclear. And that is a growing disease: it is likely that 2010 will affect 4,758 million people worldwide, compared to 1,950 million in 2010.
It can be corrected with glasses, laser surgery or contact lenses, but the condition is associated with an increased risk of visual deterioration and loss of vision in later life.
It is believed that genes play a role in the disorder but do not fully explain the increasing frequency. Given the rapid development of early-life eyes, the researchers wanted to explore possible factors contributing to the environment during the life cycle.
These experts studied 1991 twins at age 16.7. All twins were born between 1994 and 1996 in the United Kingdom and participated in &Early Development of Long Term Twins Study & # 39; (TEDS, for acronyms in English).
The ophthalmologists gave information about eye exam for myopia, and researchers analyzed demographic, social, economic, educational and behavioral factors in married couples when these children were 2, 3, 4, 7, 8, 10, 12, 14 and 16 , to catch critical phases of child and eye development.
Parents and teachers completed detailed questionnaires and twins conducted web assessments to provide a wide range of potentially relevant information and backgrounds about factors that could affect early life development.
The average age of children with myopia began wearing glasses to correct the condition was 11 years. About one in 20 (5.4 percent) had a "lazy eye" (amblyopia) and a similar share (almost 4.5 percent) had strabism. Overall, one in four (26 percent) of twins was short-lived.
The factors that were most commonly associated with the development of shortness at different time points were the educational success of mothers (university or postgraduate), hours dedicated to computer games and birth during the summer. The hours spent playing computer games can not only be linked to close-knit work but also to a shorter outdoor time, a factor previously associated with an increased risk of shortness.
Educational achievements are also associated with myopia, and as a child in the United Kingdom born in the summer months to start school at a younger age than those born during the winter months, scientists suggest that close work can speed up the growth of the eye, which is responsible for shortness of breath.
Less shortness in children born after fertility treatment
High levels of household income and intelligence measures, especially verbal skills, are associated with greater risk, but to a lesser extent. Fertility treatment seemed to protect from shortness and associated with 25-30 percent lower risk.
Researchers, members Department of Academic Ophthalmology & # 39; King & # 39; s College London & # 39;, London, United Kingdom, speculate that children born as a result of fertility treatment are often less or less premature and may have a certain level of developmental delay, which could explain the shorter eye length and less myopia.
However, this is an observational study, and as such, can not determine the cause, the researchers say, while pointing out that future research can be able to analyze the interaction between genetic sensitivity and environmental impact.
