MILANO - Non siete più dei bambini e dovete fare i conti with a lazy eye? Maybe you could help your having fun with a video game. For adults with lazy eye, amblyopia in medical terms, takes the field "the video game therapy." A study conducted at the University of California, just published in the journal PLoS Biology , indicates, in fact, already after 40 hours of "therapy" with the game (two hours each time for a total period of one month) is a significant improvement in visual acuity and, in some cases, the perception of depth. Amblyopia is a condition characterized by decreased vision in one eye is particularly common in children in whom the action taken early, can be successfully treated with the bandage of the eye that sees better than failing to stimulate.
EXPERIMENT - In adults, however there are few treatment options, which led U.S. researchers to try the way of game therapy. Preliminary data obtained on 20 individuals aged between 20 and 60 years are encouraging. In practice, participants were asked to play an action game in which they had to hit a target or a game where the aim was to build things, all having good eye bandaged. In both cases it was found an increase of 30 per cent of visual acuity after just 40 hours spent playing. In some individuals there was also an improvement of depth perception. The counter that the benefits were a result of time spent playing, not the bandage, the researchers have obtained another small experiment in which they asked some participants to put a good eye patch for 20 hours during normal daily activities such as watching television, reading, surfing the Web. Well in this case, there have been improvements, but when these same individuals have also made the video game therapy had benefits.
PLASTICITY - "We know for some time that any challenging visual activity and protracted tends to improve acuity in the eyes of amblyopic adults. The new data thus confirm that there is plasticity of the visual into adulthood - notes Paolo Nucci, professor of diseases of the eye at the University of Milan -. Some doubts concerning the improvement of depth perception (stereoacutezza). In the presence of an abnormal binocularity, is frankly hard to imagine that you re-establish a stereoscopic vision absent, while an improvement of an already present but defective stereoacutezza is common in those who apply for a long time at close range. In fact the study does not address a problem far more complex from the clinical point of view: what This facility is recovery? The present experiences indicate that the plasticity of the visual system of the adult although it may allow visual recovery, involves a similar risk of regression of the good results obtained. In short, playing video games could be a valid strategy, but it is unclear how long the benefits may persist.
