GENE MUTATIONS BEHIND MYOPIA IDENTIFIED
Nearsightedness � also known as myopia � occurs if the eye is too long or the cornea has too much curvature, which keeps light entering the eye from focusing correctly.
High-grade myopia, a more severe form of nearsightedness, affects up to two percent of Americans and is especially common in Asian populations. Individuals with high-grade myopia are at an increased risk for other serious eye problems, including retinal detachment, cataracts and glaucoma, according to the study published in the American Journal of Human Genetics.

Studies suggest that myopia is caused by a combination of environmental factors, such as large amounts of reading, and genetics. Nearsightedness runs in families, but little is understood about genetic factors that cause it.
Researchers have identified gene mutations associated with Myopia or nearsightedness - the most common human eye disease in the world, especially in Asian populations.
