Other factors such as computer games and the mother's level of schooling also seem to affect this disease, which is estimated to affect 4.758 million people worldwide by 2050. This is demonstrated by this study in twins.
Myopia is explained by consensus with hereditary factors.
In summer, computer games are linked to the increase in the risk of developing short or near myopia in my childhood (clusters of computer games dedicated to birth), which shows a study of twins published in the digital edition & # 39;Journal of Ophthalmology& # 39 ;. However, the findings may be protective of fertility treatments. (Read: The most common eye diseases in Colombians)
Myopia is defined as a break error, which means that the eye cannot focus accurately on the light and cause close objects to become clear, but distant objects appear blurred. And it is an increasingly common disease: 4.758 million people worldwide are likely to be affected by 2050 in 2010 compared to 1.950 million.
Eyeglasses can be corrected with laser surgery or contact lenses, but this is due to the risk of visual impairment and vision loss in older ages.
It is thought to have a role in the disorder of genes, but does not fully explain the increased prevalence. Given the rapid development of eyes in the early stages of life, researchers have sought to explore possible environmental factors throughout life.
These experts worked on twelve twins, an average of 16.7 years old. The twins were all born in England between 1994 and 1996 andEarly Development of the Long-Term Gemini (For TEDS, English abbreviation).
Ophthalmologists gave information about myopia eye examinations and the researchers analyzed demographic, social, economic, educational and behavioral factors in twin couples at 2, 3, 4, 7, 8, 10, and 12 years of age. 14 and 16 years to capture the critical stages of child and eye development.
Parents and teachers completed comprehensive questionnaires and the twins performed web-based assessments to provide a wide range of potential information and background on factors that could influence the development of early life.
The mean age of children with myopia is 11 years. There was 4,5 lazy eye) (amblyopia) in about 20 4,5 (5.4 percent) and there was a similar rate (almost 4.5 percent) of strabismus. Overall, a quarter of twins (26 percent) were myopic.
The factors most associated with the development of myopia at different time points were the educational success of the mother (university or graduate), the hours dedicated to computer games, and the summer months. The hours spent playing computer games are not only related to close work, but also a factor that is associated with an increased risk of myopia.
Educational success has also been associated with myopia, and as a child born in the summer months in the UK it will begin school at a younger age than those born in the winter, scientists suggest that this close study can be accelerated. Myopia is responsible for the growth of eyes.
Less myopia in children born after fertility treatments
Higher levels of household income and intelligence measures, in particular verbal skills scores, are linked to a higher risk, but to a lesser extent. Fertility treatment provided protection against myopia and was associated with a 25-30% lower risk.
Researchers, Department of Academic Ophthalmology at King's College LondonThe UK estimates that children born as a result of fertility treatment in London are generally smaller and may experience developmental delays at a level that may reveal a shorter eye length. less myopia.
However, this is an observational study and, therefore, cannot create a reason why researchers are able to analyze the interaction between genetic predisposition and future environmental impacts.
