Amblyopia is a condition where the eyes suffer from poor vision, because of failure to develop normal sight during early childhood. The main reasons for developing amblyopia during early childhood are strabismus (wandering eye/ Squint) and Anisometropia - One eye being strongly near-sighted or far -sighted compared to the other eye.
It is known as lazy eyes and cannot be corrected after the age of 9, even with the help of suitable contact lenses or spectacles. As a result of this condition the brain uses one eye instead of using both eyes. Children with amblyopia do not learn to use both eyes together because during early childhood, the brain only takes images coming from one eye while blocking the other. This blocking of one eye is known as suppression and results poor vision in that eye as it cannot get the chance to develop normally.
Causes of Amblyopia
Amblyopia can be caused due to several reasons. There are some instances where it is caused by a squint eye that lead to seeing double vision. The brain can't tolerate this condition and suppresses the wandering eye. Another reason for the cause of amblyopia is due to unequal focus. This happens when one of the eyes is more farsighted or nearsighted than the other one. As a result, one image is clearer and sharper than the other, and the brain prefers to suppress the blurred image coming from the lesser eye. Congenital cataract might also lead to amblyopia where the clear lens is clouded leading to poor vision resulting absence of effective visual stimulation. So, it is important to make sure to get it corrected as early as possible so as to avoid irreversible condition.
The classic treatment is fixing the problem in the lazy eye, either by corrective lenses or by surgical operation for strabismus, and then occluding the strong eye to force the brain to use the weak eye, and stimulate the area in the brain which is responsible for processing the vision in that eye. This however, should be done at the critical period when the brain is still plastic and developing, typically before the age of 6-9.
It is possible to improve amblyopia after the age of 9 with NeuroVision technology. NeuroVision neural training is the only clinically and scientifically proven treatment, that can effectively treat adult amblyopia. Click on the amblyopia therapy to learn more about NeuroVision amblyopia therapy.
