Researchers have demonstrated healing in kittens. Scaling up replicate these results in humans, this finding could be the solution for millions of people suffering from lazy eye, say researchers who have published their study in the journal Current Biology under the title: "Darkness Alters Maturation of Visual Cortex and Promotes Fast Recovery from Monocular Deprivation ".

While children with a lazy eye can wear a patch over the stronger eye, forcing the other eye to work harder, it is difficult to get a 4 or 5 year old wear the patch all the time, which later, in adulthood, will suffer vision impairment.

The study's authors, Kevin R. And Donald E. Duffysend Mitchell, researchers from the Department of Psychology and Neuroscience at Dalhousie University in Canada, found several years ago, the kittens had a lazy eye cells that connect the eyes to the brain smaller but to put these animals in the most this trait changed absolute darkness.

The researchers placed the kittens with a lazy eye, along with their littermates and mother, in a completely dark room. After 10 days, took the kittens of darkness. Over the course of several weeks, the researchers found that the animals were completely cured of their amblyopia.

But before this method can be used in humans, scientists will have to figure out how long a child should remain in the dark, how dark it would be and at what time of development of the child should be the treatment.
