Myopia is a common eye affliction that causes light from distant objects to focus in front of, rather than on, the retina, resulting in the eye being unable to focus at a distance. It’s increasing prevalence in the world today, particularly in industrialised nations, is a cause for great concern.
Myopia is caused by a comparatively modest overgrowth of the back part of the eye. We would like to know what genes and molecular mechanisms contribute to eye growth in general, and to the overgrowth of myopia in particular. Myopia is not only the worldwide most frequent ocular disorder in adolescence, with still no satisfying rational therapy, but also a very interesting biological problem with many open questions. After we had learned in the past years how “perfectly adapted” the optics of the human eye is to our needs
Myopia is measured in diopters ; specifically, the strength of the corrective lens that must be used to enable the eye to focus distant images correctly on the retina. Myopia of 6.00 diopters or greater is considered high , or severe, myopia. Myopia is also associated with sight threatening complications. The higher the degree of myopia, the greater the risk is. Myopia is also known as ‘short-sight’. This means that a child who is short-sighted can see better at short distance than long.
Myopia is often inherited from one generation to the next. However, the genes involved have yet to be traced. Myopia is best treated with eyeglasses and contact lenses which compensate for the elongated shape of the eye allowing the light to focus properly on the retina. As children (and their eyes) grow through the teen years, the condition typically worsens and then levels off in adulthood. Myopia is a vision defect commonly known as nearsightedness . Those with myopia can see clearly up to a certain distance, then objects begin to appear fuzzy or out of focus.
Myopia is the most common optical disorder in the world, and is on the rise in all parts of the world. The impact of myopia is evident as the driving force in the development of refractive surgery and of the eye glass and contact lens industries. Myopia is the most common eye disorder in the world, affecting one in four Americans. Several studies indicate that myopia is inherited. Myopia is usually a hereditary condition that is detected during childhood and continues to worsen until it finally stabilizes, usually in adulthood.
Myopia is a technical term for near-sight. The original members despised the game, and as for letting it influence them in their choice of name of the club, such a thing is inconceivable. Myopia is a worldwide public health problem. However, its understanding is incomplete, and many of its preventative and therapeutic aspects remain controversial. Myopia is generally classified as mild/moderate/common and extreme . Someone with mild myopia may have trouble seeing objects that are farther away, but can generally still function at the daily tasks, where as an extremely nearsighted person can only clearly see objects that are very close to the eyes.The degree of myopia is determined using diopters (D, measures the focusing power of a lens).
Myopia is a common, complex trait with considerable economic and social impact and, in highly affected individuals, ocular morbidity. We performed a classic twin study of 506 unselected twin pairs and inferred the heritability of refractive error to be 0.89 (95% confidence interval 0.86-0.91).
