Oct. 12, 2011 - PRLog -- LAS VEGAS — A new study published Aug. 30, 2011, in PLoS Biology shows that adults with amblyopia, also known as “lazy eye,” a brain disorder that causes reduced vision in one eye, can achieve substantial improvements in blurred vision by playing video games for 40 hours a week.

Amblyopia represents the most frequent cause of permanent one-eye visual impairment among young and middle-age adults. It affects about three out of every 100 American children. Although pediatric treatment options include occlusion therapy and the use of atropine drops to blur vision in the stronger eye, few treatments are currently available for adults.

While the experiment was developed to determine whether playing a video game could improve visual attention in patients with amblyopia, researchers also found that subjects saw a 37 percent improvement in spatial attention and a 16 percent increase in positional perception.

Anisometropic patients — those with two different states of near-sightedness — achieved a 54 percent improvement in three-dimensional depth perception, while some even regained normal stereoacuity, the ability to determine differences in distance, and were pronounced “cured” in that aspect of their vision.

The study, supported by the National Eye Institute, included men and women 15 to 61 years old and placed an eye patch over their good eye. Two groups used the amblyopic eye to play action video games such as “Medal of Honor: Pacific Assault” or a non-action game that required building something such as “SimCity Societies.” A third group received no therapy. Subjects played video games for 40 hours in a month in two-hour increments.

The results of the study found that subjects who played video games showed a 30 percent improvement in their vision. No visual improvement was found in subjects who did normal activities such as surfing the Internet, reading books or watching television, but the study did find that these patients saw an improvement in their vision when they later played video games for 40 hours in one month.

Subjects who played non-action games saw more vision improvements when they switched to an action game for an additional 40 hours.  

Dr. Mark Lee of Vision Source West Sahara encourages parents to bring kids in as early as 8 months old for their first exam. Children who receive treatment for amblyopia before age 2 have a 99 percent chance of eliminating the disorder. “This new treatment gives older patients a chance to correct a disorder that may have been neglected at a young age,” says Dr. Lee.

While the treatment method is still in its infancy, Dr. Lee said patients with lazy eye should not try to self-treat their condition. “This new method of treating amblyopia may be promising, but patients should consult their eye doctor. Self-treatment could lead to double vision, reverse amblyopia, eye strain and headaches.”
