Amblyopia, otherwise known as lazy eye, is a disorder of the visual system that is characterized by poor or indistinct vision in an eye that is otherwise physically normal, or out of proportion to associated structural abnormalities. It has been estimated to affect 1–5% of the population.

Treatment consists of correcting the optical deficit and forcing use of the amblyopic eye, either by patching the good eye, or by instilling topical atropine in the eye with better vision. This, according to the researchers, can lead to social stigma during a formative part of childhood
A review was published recently in Vision Research of a new computer based therapy developed by researchers from Tel Aviv University.

Dr. Uri Polat, Tel Aviv University's eye and brain specialist has developed a computer therapy that could spare kids from the ugly eye patch, letting them enjoy themselves during therapy.
And, this treatment, currently available only for adults, corrects the activity of the neurons in the brain, the main operator of eye function. The study showed that twenty hours in front of Dr. Polat's computer treatment had the same effect as about 500 hours of wearing an eye patch. In this treatment methodology, special and random objects appear, keeping the patient constantly alert and expecting the unexpected.

Researchers from Tel Aviv University have now collaborated with gaming specialists from Rochester University for developing a version of the therapy for kids.
"You see these poor kids in kindergarten wearing the patch. Everyone hates it, especially the parents who know what it's doing to their kid's self-esteem," said Dr. Polat. "As far as I know this is really a one-of-a-kind, non-invasive and effective way to treat lazy eye, without the use of an embarrassing eye patch.
"This is probably the first treatment that attempts to correct lazy eyes in adults, something that doctors had previously given up on. Doctors don't suggest intervention after the age of nine, because it usually doesn't work," he Polat added.
