VR Treatment for Lazy Eye 169

1point618 writes "According to an article at the BBC, scientist have found a new way to correct amblyopia, or lazy eye, using a virtual reality system. The system works by giving some stimuli to the good eye, but more important stimuli to the bad eye, making it work harder to get stronger while keeping both eyes in use so as not to produce double vision. Supposedly, the system will do in 1 hour what used to take 400 hours, but I'd stay skeptical of such a claim until there is a peer-reviewed paper out."

    One thing this article doesn't mention is the age of the patients. I know the amblyopia can be treated more easily when caught at an early age, when the eye is still maturing. So I think this would be an important factor to note in their statistics. A friend of mine had lazy eye when he was younger and was successfully treated with a week of wearing an eye patch and some atropine drops. But I'm thinking it would take a little more than that to help out Thom Yorke and Dr. Evil.

    I'm also curious as to what type of amblyopia this treats. Is the treatment equally effective for lazy eye caused by nearsight, farsight, astygmatism, and strabismus? If so, couldn't this also become a treatment for any of those on their own? I'm slightly nearsighted, and my optomotrist explained it to me as my eyes being too lazy to focus correctly. I wonder if I could just give them a little VR workout every now and then to beef them up...

    Is there an eye doctor in the house?

      It seems like the treatment simply addresses strength problems between the eyes. If poor vision caused the eyes to have different strength, then I don't see why not. Obviously you would have to wear contacts or have the vision in each eye corrected before using this method.

      But definitely it would be easier to be done at an early age, as after puberty there's really no way to easily create neural pathways to the brain. It's the same reason why it's easy for kids to learn languages, yet more difficult for adults. I'm sure it could assist amblyopia in adults, but it would probably be impossible to cure it.

      But if your eyes individually are having problems, then I don't think this treatment would address that. It seems to focus on differences between the eyes, versus any inherent weakness in a single eye individually.

    A somewhat related company is NovaVision [novavision.com]. I think they deal more with stroke patients though. (I am a computing nerd, not a nerd who tracks problems organic.) Their treatment was really more training for the brain though (specifically training a new part of the brain to handle vision). I'm also pretty sure they were FDA approved. It raises an intersting systems question though. Where does vision happen? Eye, brain, nervous system?

    • I am not an optometrist, but my rough understanding from a bunch of neuroscience talks in grad school is that vision is sort of pipelined, where there are a series of processing phases. One stage looks for lines (vertical, horizontal, diagonal) while the next responds to shapes formed by these lines (circle, square, ect...) and the next recognizes complex patterns composed of shapes, like faces. Movement and color gets factored in somewhere. Incidentally, the research into this partly done by strapping l

      Focusing is to do with the lens and the cornea. As far as I am aware there is no way of repairing that fault with exercises.

      Lazy eye is caused by the brain essentially cutting out falty information being recieved from one eye and ultimately forgetting about it altogether. Exercises (and originally eyepatches) would force the brain to get it up and running again.

    ...I'd be interested to see if this actually pans out. Patching is what caused my lazy eye to become as bad as it is.

    I've had corrective surgery for my strabismus three times, and each time has made significant improvements, but most of my vision still comes from my one good eye. I'm one of the lucky ones - I have a good null point, so my eyes don't bounce all the time. I can drive just fine. :)

      Which leads to my question: Has your overall vision improved?
      I'm thinking that, if your brain is using one eye because the other is inferior for whatever reason, then doing anything to use both eyes would decrease your overall quality of your vision. Although, it sounds like that the "bad" eye was being corrected so that your vision would improve,

      • In my case (as is the case with some other strabismus sufferers), both eyes are physically good. Strabismus is a condition where your eyes are crossed severely. In my case, my eyes pointed directly at my nose when I was born. My brain shut down most of the input from the right eye because it was confusing. Unfortunately, being as my issue is neurological, the opthamologists haven't come up with a way to correct it.

        My vision has improved over the years, but I will never have fantastic depth perception.
    • BTW, the medical term for lazy eye is actually occular nystagmus.

    Any more direct method that was at all effective couldn't help but be a dramatic improvement over eye patches for hours a day.

    The Docs consulted prescribed the usual regimen of eye patches and so on for my daughter as a quite young child. I can say from experience that it's not easy to get a child of that age -- and treatment when young was strongly preferable -- to live with the patch. Even when she wasn't particularly annoyed by it, we were dealing with something on the level of brushing your teeth in a little kid. My parenting skills weren't up to the task, and our treatment was hit and miss.

    Eventually my daughter's lazy eye has come around by itself, more or less. I'd much rather have been able to intervene with a more active measure, though.

That "lazy" eye will then start looking outward and I'll get double vision, but how noticable it is depends on how out-of-whack my eye convergence is (I can also control how much convergence I loose, so I can go from slight, almost overlapping double vision, to nearly completely different viewpoints). If I'm looking at something to the extreme right or left I usually end up looking with just one eye, but I don't notice the double-vision for some reason. I've since learned to physically turn my head / body towards what I'm looking at since that makes it physically possible for me to look at something with both eyes. Another trick I use is to look at something with my "outside eye" (i.e. if I'm looking at something to my right, I will look at it with my left eye, visa-versa if looking left). I'm not sure if that makes sense to anyone, but AFAIK, most people should be able to "look" through either of their eyes at will. Over time, I've managed to adapt my behaviour so that most of the time these symptoms don't occur.

    The most dangerous downsides to all this is that when I get extremely tired, or very drunk, I can no longer keep my eyes converged and normal vision becomes impossible. Nothing short of intensely focusing on a high-contrast area (say, the sharp edge of a table) will bring convergence back. However, I'm not sure if this happens because of my lazy eyes, or if it happens to other people. Driving while tired is extremely dangerous for me, especially at night, since I loose all sense of depth perception when I get double-vision and I suddenly have no idea which lane I'm in or where I'm headed.

    One interesting aspect about all this is that if I cover one eye then I can no longer get this behaviour to happen, which has saved me a few times during extremely boring lectures! Something about looking with both eyes causes the trouble.

    i have amblyopia in my left eye and had it treated when i was 4 (am now 24), and there is also some astigmatism. additionally, that eye is far-sighted, while the right eye is near-sighted. it's still not corrected and i wonder sometimes if it ever will be. i cannot do anything with my left eye because it is so weak. i hope that someday this type of treatment will be a viable option as it's really a very annoying problem to have.

    Is there an eye doctor in the house?

    I'm a neurologist, not an ophthalmologist, but perhaps I can help...

    Amblyopia is a defect in the processing of visual spatial information that affects the visual pathways in the brain NOT the eye. It is developmental in that there is some problem in an eye from an early age that prevents proper binocular vision, for example a congenital cataract, or a problem aligning the two eyes, i.e,. weak muscles or strabismus.

    What is thought to happen is that the brain's v
  • I have amblyopia and I often wonder what the value is in having both eyes work together if one is inferior (and can't be corrected). The brain is ignoring the bad eye for a reason. The images just don't match up. What purpose does it serve to force your brain to match the images up? Is it cosmetic? Does it not reduce the overall quality of vision? Seem to for me.

  • My optometrist (well known in my area) told me that the reason why my left eye is lazy is because I have a cornea in my left eye. I've had this in my left eye since childhood. I asked him clearly what could be done, and he said after childhood, you really can't fix a lazy eye. Before childhood, a lazy eye can be trained and improved, but not so in adulthood. My optometrist told me there was nothing wrong with a lazy eye, especially at my age, and that I should just learn to deal with it (and take care o
  • I don't see why one should be so skeptical of the claims (other than being skeptical of *any* claim to a certain degree). Targeted training by computer can be incredibly effective. I remember in high school, having to learn huge lists of authors and the books they wrote; it just wouldn't stick with me. So I wrote a little program on my Z-80 box, that quizzed me, focusing heavily upon the ones I had trouble with. It was amazing how such a simple tool, that focused upon my mental weaknesses, kicked me int
