Amblyopia: how to recognize and cure the lazy eye
Amblyopia is an alteration of the vision that is to occur initially during the first months of life. In his understanding of the term this disease comes from the greek "ops" (vision) and "amblyos" (lazy), in fact, the name by which it is best known is lazy eye syndrome.
The alteration of the initial visual development may be due to an eye blurring or a misaligned eye. Subsequently, when the fire is corrected with the lens or the alignment is corrected with surgery, the visual loss is re-established, even if, in some, this can not take place completely.
Generally there is considered in the presence of amblyopia when one eye over the other bears a 3/10 difference.
It is affected about 2% of the entire population and about 4-5% of children.
In young people under 20 years old is considered one of the leading causes of visual impairment.
The lazy eye symptoms are generally not reported directly by the patient, which, as anticipated, in the vast majority of cases is too small to be able to expose a bottom view in one eye than another. That\'s why it is always recommended to refer to an eye examination the child, even without the presence of actual symptoms within the first 2-3 years of life.
Better still anticipate such a visit in the first year.
Most of the time, reportedly, amblyopia is unilateral as it affects only one eye, but rarely can also occur bilaterally going to affect both eyes.
The most frequent causes which generally underlie dell\'ambliopia are:
The refractive defects, primarily definitely farsightedness, astigmatism and myopia, which is to transfer the image less sharp in the cerebral cortex, impeding the normal development of brain cells deputed to the vision;
Strabismus, which, by supporting a mechanism of rivalry between the two images of the retinas, forces the brain to suppress one of the two visual channels.
Other causes such as congenital ptosis or cataracts affect, fortunately, to a small extent. A threat this in part averted, since in these conditions amblyopia would be much more difficult to treat.
Treatment and care dell\'ambliopia
Treatment of amblyopia has always understood the healthy eye patching aimed at forcing the lazy eye to work. The patching is usually done by means of an adhesive patch that is applied from 3 to 6 hours a day, within 6 months to 2 years.
Subsequently the occlusion becomes softer and takes place making use of special tissue adhesive to be bonded to the eyeglass lens designed to ensure the vision anyway.
In adults, however, this treatment may not Sorting particular benefit.
This is because the eye is now formed, so it is not "plastic", responsive, like that of the child. However, you can achieve improvements, even if temporary, means of special contact lenses that generally are worn while sleeping and which allow a total recovery, albeit temporary, of the view.
However, these treatments are effective if amblyopia were treated during childhood and normal development of vision has been extended in the pediatric age years.
Other new technologies are based on the use of Gabor filter and neuro- visual stimulation that produce tangible results, even in adults.
The frontier of medicine offers us a lot, but intervene in preschool, in this case more than ever, it is really saving to get inconclusive results.
