Washington: University of Maryland-led research team has found a new hope for treating "lazy eye" and other serious visual problems that are usually permanent unless they are corrected in early childhood.Amblyopia afflicts about three percent of the population, and is a widespread cause of vision loss in children.It occurs when both eyes are structurally normal, but mismatched - either misaligned, or differently focused, or unequally receptive to visual stimuli because of an obstruction such as a cataract in one eye.During the so-called "critical period" when a young child`s brain is adapting very quickly to new experiences, the brain builds a powerful neural network connecting the stronger eye to the visual cortex.But the weaker eye gets less stimulation and develops fewer synapses, or points of connection between neurons.
