Potential Canadian breakthrough in “lazy eye” treatment


It’s a potential new cure for amblyopia, or lazy eye which affects about three percent of the population.

Canadian university researchers and tech companies have developed an entirely new technique and technology to treat the condition using video games.

Traditionally, the condition has been treated with a patch over the “good” eye in order to force the weak eye to work harder.

Professor Hess says however, the problem is not really with the eye, but rather the connections in the brain where the eye signals are translated into an image.

Radical change : treating not as a single-eye problem, but a two-eye condition

He says the traditional treatment had a number of drawbacks not the least of which is that it wasn’t particularly effective. He says it still treated the issue as a “monocular” problem which still put one eye “in competition” with the other.  His group realized it was a binocular problem and began to develop treatment based on developing a better working connection between the two eye signals.

The patents developed by the McGill researchers including Robert Hess, Benjamin Thompson, Behzad Mansouri, Jeremy Cooperstock, Long To and Jeff Blum were licensed to Amblyotech of the US, who in turn worked with software developer Ubisoft in Canada  and together thr group created  a new game called “Dig Rush”

It does not block an eye but rather helps one eye to see some images better, while the other eye sees other images better, and some images are seen by both eyes. The game(s) can also be adjusted depending on the particular visual requirements of each individual

The game is designed to be fun to play to encourage patients to stick with it. Unlike the patch, the treatment is  of much shorter duration, and has had much better success in trials.

This is not a game for general consumers but is in fact a medical device to be used with a prescription, and as such may be the first “pharmaceutical video game” ever.

Because of that, professor Hess says they are now awaiting medical approval from the FDA for use and the game may be available for clinical use perhaps as early as late this year.

He also says this kind of technology and collaboration may lead to similar developments for other medical conditions in the near future.

Netiquette »

When you express your personal opinion in an online forum, you must be as courteous as if you were speaking with someone face-to-face. Insults and personal attacks will not be tolerated. To disagree with an opinion, an idea or an event is one thing, but to show disrespect for other people is quite another. Great minds don’t always think alike—and that’s precisely what makes online dialogue so interesting and valuable.

Netiquette is the set of rules of conduct governing how you should behave when communicating via the Internet. Before you post a message to a blog or forum, it’s important to read and understand these rules. Otherwise, you may be banned from posting.

  1. RCInet.ca’s online forums are not anonymous. Users must register, and give their full name and place of residence, which are displayed alongside each of their comments. RCInet.ca reserves the right not to publish comments if there is any doubt as to the identity of their author.
  2. Assuming the identity of another person with intent to mislead or cause harm is a serious infraction that may result in the offender being banned.
  3. RCInet.ca’s online forums are open to everyone, without regard to age, ethnic origin, religion, gender or sexual orientation.
  4. Comments that are defamatory, hateful, racist, xenophobic, sexist, or that disparage an ethnic origin, religious affiliation or age group will not be published.

Any message containing one or more words in all caps (except for initialisms and acronyms) will be rejected, as will any message containing one or more words in bold, italic or underlined characters.
  6. Use of vulgar, obscene or objectionable language is prohibited. Forums are public places and your comments could offend some users. People who use inappropriate language will be banned.
  7. Mutual respect is essential among users. Insulting, threatening or harassing another user is prohibited. You can express your disagreement with an idea without attacking anyone.
