Study: Video games improve vision in people with “lazy eye”

Study sees that video games can contribute to improve vision and stereoscopic vision in patients with “lazy eye”

Canadian study found that video games can help improve eyesight for adults with what is known disease “lazy eye” in a few weeks. The disease affects about 3% of people around the world without the presence of an effective treatment for adults.

Disease known as “lazy eye” medically as Amblyopia or Ompelyubia, where a person sees one of his eyes better than the other leading to the brain to ignore the weak eye. The injured suffered from the inability to three-dimensional vision, in addition to their inability to measure distances with the same efficiency of natural persons with sight; because these tasks require the use of both eyes at the same time. May also be accompanied by “lazy eye” some “squint” Eyes do not look in the same direction.

And ensure treatment during the study , which was conducted by researchers at McGill University in Canada, a Tetris game that depends on the player to cut recycling while falling to integrate with the rest of the parts of the bottom of the screen, the game requires the use of both eyes.

And adopted the study , published this week in the journal Current Biology, eighteen people from volunteers infected with “lazy eye” were divided into two groups. The study monitored a significant improvement in the weak eye to the nine participants also improved their ability to stereoscopic vision of things, and after two weeks of play Tetris for an hour a day during the wearing of certain glasses.

During the experiment, the researchers split the picture between ÚĎÓĘí bifocals; eyes so that you see one of the falling blocks from the top only, while others see the pieces at the bottom, as they changed the degree of variation in the colors of the picture, seems the picture you see the stronger eye to a lesser degree of variation.

While the other group included nine participants played the same game with a strong eye coverage, and these showed an improvement in the ability of the weak eye sight but improvement increased significantly after they used both eyes to play with the division of the image.

And the role of Tetris game specifically in the treatment, said Robert Hess, Head of Research of Ophthalmology at McGill University who oversaw the research team, the success of the treatment is not about them; it is possible for any accurate game visually or activity that requires the work of both eyes to be effective.

Estimates of the injury and one out of every fifty ill child “lazy eye”, doctors are trying to intervene early remedying; as neglect may lead to loss of vision in the weaker eye.

It is familiar to children treatments strongest cover the eye with a cloth, forcing the brain to use the weak eye, thereby improving their ability to vision, but this treatment does not work in cases of older persons.

The study considers contrary to scientific belief that has prevailed for a long time that the reason not to treat “lazy eye” in adults lies in the back of the brain. And suggest instead, that the problem is in the eye of the strong blocking communication between the brain and the weaker eye, the more contrast in the images is visible to the eye whenever strongest hindered the arrival of the signals from the weaker eye.

Robert Hess said that the payment of the eyes to work together more than of planed adapt in the brain, and allows the weaker eye to learn the vision again, and improves the sense of sight. Hess described a method of treatment using video games are more fun and faster than cover one eye. He added that most of the people involved have regained their ability to stereoscopic vision.

Planning researchers to test the same method of treatment with children in order to create a more enjoyable and entertaining and effective rather than cover one eye, as this method requires the child to cover one of his eyes for a period ranging between three and six hours a day for a period of six months to one year, and that this method does not lead to use Alaann together and over time, less than the capacity of the weak eye again.

The scientists at the University “Glasgow Caledonian” in Scotland had announced last year for the development of a cure for “lazy eye” in children through a video game using certain glasses, their research is still in the testing phase.
