Topic: Myopia



  
 Myopia - Wikipedia, the free encyclopedia
Myopia, sometimes called near-sightedness or short-sightedness, is a refractive defect of the eye in which collimated light produces image focus in front of the retina when accommodation is relaxed.
Another theory is that myopia is caused by a weakening of the ciliary muscle which controls the eye's lens.
Practitioners and advocates of alternative therapies often recommend eye exercises and relaxation techniques such as the Bates method, however, the efficacy of these practices are disputed by mainstream eye care practioners.

 Nearsightedness (Myopia)
However, if myopia is combined with astigmatism, one can experience headaches.
Myopia is rarely linked with headaches or eyestrain, as the eyes are naturally focused for near vision.
Myopia is very common and can be corrected by the use of appliances, such as glasses or contact lenses with a prescription, or by refractive surgery.

 Myopia / Short Sightedness
Myopia is best treated with eyeglasses or contact lenses which compensate for the elongated shape of the eye allowing the light to focus properly on the retina.
Myopia or short sightedness is a vision problem experienced by almost one-third of the population.
A Many contact lens specialists agree that the use of Oxygen Permeable, or RGP (Rigid Gas Permeable) contact lenses, that are rigid by construction, may slow or retard the progression of shortsightedness, whereas spectacles or soft contact lenses offer no benefit of this type.

 Myopia
Myopia, or nearsightedness, is a condition of the eye in which objects are seen more clearly when close to the eye while distant objects appear blurred or fuzzy.
Another explanation for disagreement regarding the role of heredity in myopia is the sensitivity of the human eye to very small changes in its anatomical structure.
It is possible that by combining exercises with changes in behavior, the progression of myopia may be slowed or prevented.

 Myopia (Nearsightedness) Treatment - AllAboutVision.com
Nearsightedness, or myopia, is a vision problem experienced by up to about one-third of the population.
In clinical trials, this treatment stabilized or improved vision in 72 percent of patients after one year, versus 44 percent on placebo.
Nearsightedness usually is a mildly debilitating condition that is easily correctible, in most instances with glasses, contacts or vision surgery.

In contrast to the focussing of the normal (emmetropic) eye, in which the image of the visual field is focussed on the retina, the image may be focussed in front of the retina (nearsightedness, or myopia), or behind the retina (farsightedness or hyperopia).

 The Neural Basis of Myopia
In the U.S., the prevalence of myopia is about 25 percent of the population, but in Asian countries such as China or Japan it may exceed 70 percent, and it approximates 90 percent in selected populations, such as Chinese university students.
Although at the present stage of our investigations it is premature to draw any conclusion as to the human condition, it may be worthwhile to formulate a set of hypotheses that may be useful in designing clinical studies.
The main achievement of our studies was the realization that the nervous system plays a fundamental role in the development of myopia and that a drastic change in the visual environment may affect the postnatal growth of the eye.

 Blame lifestyle for myopia, not genes
The epidemics of myopia in countries such as Singapore and Japan are due solely to changes in lifestyle, they say, and similar levels could soon be seen in many western countries as lifestyles there continue to change.
CONTRARY to popular belief, people in east Asia are no more genetically susceptible to short-sightedness than any other population group, according to researchers who have analysed past studies of the problem.
There is also an increasing incidence of extreme myopia, which can lead to blindness.

 The Genetic Basis of Myopia
A family history of myopia is associated with the likelihood of developing the condition.
For example, a greater prevalence of myopia exists among the children of myopic parents than among the children of non myopic parents; (Zadnik, 1323) the probability of myopia in offspring of myopic parents up to three times higher than when neither parent is myopic.

The end of school age (around 18/22) is generally considered as the period of life when myopia growth stops and the recent trend is to consider, from this age onwards, some more or less established surgical techniques to reduce myopia.
According to the functional/environmental theory it is possible, to work on the causes of myopia after having detected the early forewarning signs of a trend in those individuals who are not yet myopes.

The idea, to find just one mechanism for myopia and to solve this problem once and forever sounds very tempting, and quite some authors are giving the impression that they are very close to this target, and that most of the promoters of other theories and observations are wrong.

It is by far more likely, however, that all of them are right in the very specific view of their experiments and experiences, because various different - and overlapping - mechanisms towards myopia are obviously existing.
