New hope for adults with amblyopia (lazy eye)

By Professor Robert Hess

Robert F Hess ARTICLE IMAGE

Amblyopia is a visual developmental disorder in which the vision through one eye fails to develop properly in early childhood. The deficit is not in the eye itself but in the visual areas of the brain.

The disruption to early visual development can be due to a misaligned eye or an eye out of focus. Later, when the alignment is corrected by surgery or the focus corrected with lenses, the visual loss remains.

The treatment for the last 200 hundred years has involved patching of the fellow sighted eye, under the rationale of forcing the “lazy” eye to work.

Not too long ago, the patching was all day, but more recently, it has been restricted to 3-6 hrs a day.

In the majority of cases this does produce visual improvements, though there is a great deal of variability.

The cost in terms of inconvenience and psychological stress for the patient, usually a child at school age, is tremendous and the compliance is often low.

The end result after 6 months to 2 years of patching is certainly improved function in the majority of cases, but once the patch is removed the two eyes often don’t work together as they should, 3D vision is often not obtained and the fellow eye suppresses the amblyopic eye, which eventually leads to some reduction in acuity.

More significantly there is only a limited time-window in which the patching therapy works, kids are only patched up to the age of 12 years. There is no treatment offered to adults with amblyopia.

The current treatment approach is based on the assumption that amblyopia is the primary problem and the loss of binocular function is the secondary consequence.

The fact that reducing amblyopia with patching does not automatically lead to improved use of the two eyes together makes one question its validity.

There is reason to suspect the logic needs to be reversed, namely that the primary problem is that the two eyes, because of either an eye misalignment or an eye out of focus, stop working together with the secondary consequence being amblyopia. The link between disrupted binocular vision and amblyopia is suppression.

All amblyopes have some degree of suppression where the fellow sighted eye inhibits the functioning of the misaligned or out of focus eye to avoid the confusion resulting from a double or blurred image.

It seems perfectly feasible that over time this constant suppression leads to a more permanent loss of vision or amblyopia.

Recently we have developed tools for measuring suppression and shown that there is a direct relationship between suppression and amblyopia, consistent with the idea that the primary problem is the loss of binocular function with the secondary consequence the development of amblyopia.

This new way of thinking about the genesis of amblyopia leads one up a different treatment path, one that tackles the loss of binocular function as a first step with the expectation that the function through the amblyopic eye will improve as a consequence of the reduced suppression from the fellow eye.

With this new way of thinking about amblyopia in mind we developed a method of measuring the degree of suppression and arranging viewing conditions using dichoptic presentation (different images to each eye) where the suppression would be minimal.

Under these rather artificial (compared with natural viewing) viewing conditions we found that the two eyes were able to combine information normally. In other words, it was just the suppression that rendered that was a structurally intact binocular visual system into a functionally monocular one in amblyopic observers.

Furthermore, the more time the eyes worked together combining information (for the first time), the stronger their binocular capacity became and over time, the viewing conditions could be slowly moved in the direction of more normal viewing where both eyes sees the same images.

We (with my colleagues Drs Mansouri and Thompson) found that the binocular training only had to be done for 1 -2 hours a day for 4-6 weeks, after which the two eyes could work together under natural viewing conditions.

Once this was achieved we also showed that there were improvements in 3D vision, with some patients experiencing this for the first time.

The acuity of the amblyopic eye also improved as a result of eliminating the suppression from the fellow sighted eye. Even more remarkable all these results were obtained in adults, some of whom were middle aged, for whom there is no current treatment.

All of the above work was done in the laboratory using space consuming computer equipment. We then teamed up with our colleagues at McGill in Electrical Engineering (Drs Cooperstock, Long and Blum) and, using the same principle, converted it to a video game on an ipod. This introduced the first bit of fun into a treatment that has been anything but fun for the last 200years.

Tetris was used and it could only be played successfully if the amblyope truly combined the information from the two eyes because the information seen by each eye was different and both bits of information were used to play the game successfully.

We initially adjusted the dichoptic images for each patient to ensure that their suppression was minimal. As they successfully played the game, the viewing conditions were automatically adjusted in the direction towards normal viewing.

Depending on the patient and the degree of suppression, normal binocular function under normal everyday viewing conditions could be obtained within 4-6 weeks after 1 hrs of daily play.

The improvements in 3D vision and monocular acuity of the amblyopic eye were comparable to what we had found previously in the laboratory.

Initially we ran an in-office treatment study where we could ensure exact compliance and more recently we have run a take-home study and assessed compliance from the log files of the video game stored on the ipod. The compliance was excellent and the visual improvement comparable to our previous studies.

Very recently, we (Drs Li, Thompson, Chan, Yu and Hess) we assessed the current patching treatment with our dichoptic treatment. Amblyopic patients were divided into two comparable groups matched for the degree of amblyopia.

One group played tetris while being patched for 1 hrs a day for 2 weeks, the other group played tetris dichoptically (as described above) for 1 hrs a day for 2 weeks.

We measured 3D vision, degree of suppression and monocular vision. On all three measures, the dichoptic treatment was far superior to that of the monocular patching.

Furthermore, when the monocular patching group were crossed over to the dichoptic treatment, they too achieved comparable gains in each of these visual measures to that of the original dichoptic group, suggesting that the dichoptic approach, based on treating the binocular deficit, improves the function of the amblyopic eye more than the current patching approach.

Additionally, it does so with the extra benefit of having two eyes that work together that in turn ensures that any gains achieved in the function of the amblyopic eye will be maintained and not regress.

All of the above work was supported by a grant from the Canadian Institutes of Health (#53346) to RFH.

    Hi there.
    I'm very interested in this treatment. I'm a 33yo amblyopic (weak left eye with 40% vision) and I'm from Spain.
    Here in Spain, amblyopia doesn't have any treatment at all, every single ophthalmologist says that amblyopia can only be treated before the age of 10 and the only therapy is patching the strong eye before the age comes.
    I don't know how can I get close to a treatment. I want to improve my visual acuity.
    Does anybody know how frustrating is it when your buddies talk about how amazing is Avatar in 3D and not really knowing WHAT does it mean... Or how frustrating is declining a movies evening because the movie you're going to watch is in 3D...
    How can I get to this treatment?
    I've been treated with Lasik in both eyes, this was good, but not enough.
    I'd appreciate any help.

    Thank you!

    Hello everyone , I'm from Egypt and I have an amblyopic eye ( right eye is 50 % ) and I wear glasses Frown I'm really interested in the treatment and I wish I would know anything about it .
    The doctors here would say even if your are 16 year-old-boy but the treatment is only for children under 9-10 years and that causes me depression  Frown( I wish to have a normal eye
    Can you help me please ?? Smile

  3. Margaret Moneys Margaret Moneys United Kingdom says:

    My 6 year old son suffers from a lazy eye, something I have had for 30 years but have had no option but to live with due to it not being picked up early enough.

    I really don't want my son to suffer due to this and after almost 2 years of wearing glasses and 3 monthly visits to the hospital he doesn't seem to be making any improvement and the next step is to wear a patch (something I would like to avoid if at all possible due to the psychological effects).

    How would I go about having my son involved in trials? The optician at the hospital isn't seem to be aware of this type of treatment in the UK.

    I would be grateful for any advice. Thanks

    • Gwynfryn Thomas Gwynfryn Thomas France says:

      Margaret, does your son fully understand that he needs to be concentrating on seeing things with his week eye? Things like trying to focus on large letters, at different distances? I went through this as a kid (still essentially blind in one eye) with the patches, and they kept repeating “you’ve got a lazy eye”, but I never got the notion of what I was supposed to do with it (boy, was I angry when it occurred to me in my teens, “too late”, as I was then told!). I can’t promise it’ll make any difference, but it should be worth trying! Isn’t it annoying that they mention their app/video game, but don’t provide a link to it: I want to try it right now, not after trolling the net, possibly unsuccessfully!

  4. Abhilasha Ahuja Abhilasha Ahuja Qatar says:

    Hi

    My name is Abhi and I am 45 years old.

    My right eye is Lazy from birth. My parents realized that I had a lazy eye when I was  16 years of age and going to the University. It was too late for the treatment the doctors said. The vision in the Lazy eye is 6/60 and the correct eye is 6/6.

    As it is very difficult to see with the lazy eye the thought of something happening to my good eye scares me a lot.I would really be interested in the treatment if possible in my case. Please advice weather this might work for me or not.

    thanks

  5. Aimee Henderson Aimee Henderson United Kingdom says:

    I remember having to be patched as a child. It really isn't what a young child needs in their day to day life. My right eye is still very weak, though the alignment was fixed at an early age. It would be great to see treatments like this available for adults. (Maybe I'll even be able to see a 3D film and see what all the fuss is about!)

  6. Brian Clancy Brian Clancy Ireland says:

    It's impossible to understand what this article is saying - typical of specialists.

  7. Will Do Will Do United States says:

    I have a lazy eye and something puzzling has occurred.   First a little history, I first noticed it when I was around 16.  I inquired about fixing it and I was told that I was too old.  To prevent squint, I tried to exercise my eye.  As the years went by I just adjusted to my lazy eye but I focused mainly out of my good eye.  I am 67 now and up until about 2 years ago I could not see anything clearly out of my lazy eye even with glasses.  For some reason the vision in my lazy eye improved.  The doctor said that I have cataracts so I decided to have them removed.  Before the cataract surgery the vision in my right eye was 20/80 with my glasses.  After the cataract surgery and implant my vision improved to 20/25.  I still cannot understand how my vision improved from being somewhat blind to 20/25.  My ophthalmologist was amazed at how much my vision had corrected.

  8. Richelle Danganan Richelle Danganan Philippines says:

    i have also a lazy eye on my left eye..i was 25 right now before i go to a doctor and they told me that i have a lazy eye..i cant read using my left eye and i only see a haft vision...and the doctor said that my optical nerve is damage and it can lead to total lost of vision..is it possible to correct my vision at my age..or to improved my vision..pls help...

  9. Ahmed Noman Ahmed Noman Islamic Republic of Pakistan says:

    hi, im 30 and from pakistan and i also have a lazy eye problem.. when i was a kid i remember doctors used to say i have a squint.. but just after recently when i read it on the web that its actually the lazy eye that im suffering from becomes really frustrating.. i couldnt see from one eye properly even though my eye sight is 6 by 6.. more frustrating is that the vision is reducing from the effected eye every year.. i can pray to God that everyone included myself who is suffering from this disease should get rid of it..
    plus i have been flying kites all my childhood but that couldnt help either. so i dont think playing games would work.. i think its all lies inside our brain and very much related with the nerves, we actually lack power and energy in our nerves attached to the effected eye...
    wish you all good health folks!
    regards,

  10. Tony Warren Tony Warren United States says:

    I'm 59 years old and as a child had two eye surgeries and did eye patching. Unfortunately my right eye is still suppressed. A possible treatment for adults with amblyopia would be amazing. Please sign me up even if it's just for a clinical trial.  Keep up the good work.

  11. Kimberly Marie Kimberly Marie United States says:

    I am 38. I have had a lazy eye since I was a baby . My right eye. I had muscle surgery as a baby. I wore the patch for a while in elementary school. It is getting worse now. I'd like to try this treatment. I could never pass a depth perception test or enjoy a 3d movie. I'm tired of people noticing. I also passed it down genetically to my daughter. She is 16 and her issue seems slight. I'm sure it will get worse with time. Contact me please.

  12. Margaret Melfa Margaret Melfa United States says:

    I am 47...i was born with esotropia, and have had 3 surgeries to keep my left lazy eye aligned...most recent surgery in 2001. My parent patched the good eye when i was under 3 yrs of age, but nothing really helped permanently. When i'm tired my weak eye drifts more, and it is hard for me to keep it focused. I only have one "good eye"...when i cover it, i can't read past the first line on the eye chart. I would love info on any types of new treatment available!!!

  13. Christopher Pa Christopher Pa Germany says:

    I have a mild amblyopia in my left eye (80% vision) and alternating strabismus since I was a baby. Is there a danger of double images when the supression is reduced? Or is it possible to restore the binocular function that is currently not working?
    Thanks!

    Hi. I am 33 from Slovenia and also suffering from amblyopia on my right eye. For now my left eye is completely healthy and my vision is 100%, but the thought of something happening scares me, since my right eye vision is very poor.
    I too am interested in this treatment.

      Hello now I am 20 and have had Amblyopia since birth in my left eye but I came to know about it when I am 16 yrs where I am preparing for IIT JEE, by that time when I asked for solutions, doctors said time is up ,if i had went before 10yrs, 100% and before 15yrs , 50% rectification of problem could be done
      but they put me off saying i came very late and they advised me to do 6hrs of Patching but i got into IIT MADRAS , mechanical engg, now 4th yr, could not able to spend 6 hrs for patching but trying to manage for 1 or 1 1/2 hrs daily

      now after check up my power details are :
      right eye : 6/6 : -0.5 power
      left eye   :  6/36 : +5.5 or +6 approximately

      I did the patching method but not worked. I am also very much interested in any information for a treatment you could share. My email is bhuvansarakam@gmail.com

  18. Enrique Acevedo Enrique Acevedo United States says:

    I am 46 and have been told that I could not even get Lasik on my good eye because their insurance would not cover the clinic if they screwed up and permanently damaged my good eye.  I thought I had no options until I read this article.  Did not get diagnosed early enough.  I would love to be a subject in your study.

  19. Israel Hlychho Israel Hlychho India says:

    Hi there, I'm 23 and I have amblyopic right eye. Doctors told me that the retina in my right eye is clouded by some white thing, which they are not sure of what it is. They told me that it could not be removed by surgery because there are so many risks in the process, and that the sight could be improved only upto 70%. So I am wondering if binocular training could bring me any improvement in my sights (of course for my right eye), because wearing glass tickles my face and does not work at all for my blurry vision, or any vision related problem in my right eye for that matter. I'd very much appreciate to receive your suggestions.

  20. Jo Carpenter Jo Carpenter je says:

    Hi, I am a 48 year old woman who has an amblyopic left eye. I went cross eyed at 2 and doctors removed a bit of muscle out of each eye. I was left with a lazy left eye. I was patched for a long time as a child and it was horrendous. Kept walking into things and it was so uncomfortable and very frustrating. Now that I am older, and I do a lot of computer work, my eyes get really tired but my poor lazy eye just closes now. It closes a lot, even in just a slight breeze too as it is so sensitive. I don't really understand the article as its written in doctor language, so I have emailed it to a doctor friend of mine to disseminate it for me. I would love to be part of a trial to see if your technique works. Please contact me if this would be at all possible. Many thanks and the best of luck to everyone out there, Jo

    Hello everyone, I am Oprea Stefan and I am 14 years old from Roumanian,Europe. Here we don t have a good tratament for amblyopia, my left eye is 50 with glasses, and my right eye is 100 (so he don t have problems) as I child I don t have money to do many things but I have a natural life style, I patched my eye 3 hours on day and I do exercices for my eyes, To be honest the result is very good I know I will have a normal eye, I think I see 3D, I mean when I was child my eye got patched too, I am sure I see 3D and I have a binocular vision too, but I want to be sure, so I will folow all natural trataments and I do what is in my power to see absoluty normaly, because I want to become a footballer and play in Europe. Hope all of you who see this comment will see normaly, I am sure you will. I am sorry for my bad english. Bye,bye!

    Hi,
    I was born cross-eyed, had surgery to correct my eyes and wore a patch when I was very young. I hated the patch, and have been told I used to remove the patch often....
    I now have a lazy eye (right eye). I also have double-vision as a result of my eyes not working together. Not sure if other people here also have double-vision? It's something I've grown up (I'm 48). I'd like to have the correction done to my right eye (I am not so concerned about "better" vision in my right eye; I would like just to have my eyes aligned)... on a daily basis I get people turning their head to look behind them when I am talking to them (because they look at the lazy eye, which is pointing outward). I've tried to deal with this my entire life. My daughter (she's 5 1/2) will soon be asking why daddy's eyes aren't aligned. She'll probably turn her head too when I talk to her. I hate having to drive my vehicle when my wife is with me. Because I use my left eye for EVERYTHING, I tend to turn my head slightly to the right... so my left eye sees "Middle" (if that makes sense?). She has commented more times than I care to think about, "Keep your eyes on the road!". I have to then explain to her that I am. How embarrassing. Or when I turn to look at her, I have to turn my head far to the right (so I can see her with my left eye!) It makes me look as though I am peaking into the back seat!! Again.. how embarrassing. Or when I'm having a conversation with a co-worker... sometimes I can see the image from my right eye (double-vision, remember) and the eye is pointing outward... so not only do I see something off to the right, but my co-worker clearly sees my right eye off in la-la land. How embarrassing.
    I consider myself to be very thick-skinned... and I don't break down easily.. but talking about my lazy eye (and/or seeing somebody turn their head when I'm talking to them) can easily bring me to tears.

    During a recent visit to a NEW optometrist, she discussed the Prism fix for my eyes. Sadly, the glasses with the prism did nothing to bring in my right eye. He's a stubborn old cout...I'm staying out in Right Field!!!!!

    I was wearing a patch up to a while ago. It was just too difficult for me to go about my daily routine. So I stopped wearing the patch. Not to mention the wicked headaches I was getting.

    So let us rejoice all of us with lazy-eye!! Surely, if they can send men to outer space, they can find a cure/fix for lazy eye! Even when we are already into our adulthood.

    BTW: With contacts/glasses, I have 20/20 vision in my left eye and 20/200 in my right eye, so pretty much blind the right! Given the choice, I would rather have minimal vision in my eye versus being blind. I have never enjoyed a 3-D movie, and when my family and I visited Universal Studios, in California in 2012, I truly missed out experiencing the joy that my daughter was experiencing from the 3-D and 4-D movies! Literally everyone in the theatre would jump when things were "popping out of the screen", except for me.... I was left asking, "What happened?" How embarrassing.

    I'm not at a point in my life where I am considering having surgery to correct my lazy eye (for cosmetic reasons only.)

  24. Dave S Dave S Canada says:

    I'm interested!!!!!

  25. Lowell Thompson Lowell Thompson United States says:

    I am also interested in this treatment. I am 47 years old and have lived a great life in spite of my amblyopia. As I age my vision get worse (-7.50) in my good eye now. I was told I was about 20/400 in my right eye. If there is anything you could do for me I would greatly appreciate it.

  26. Dhia eddine Bedoui Dhia eddine Bedoui Tunisia says:

    Hi there, i'm very interested and excited about this,i'am a tunisian boy, 20 years old I got a lazy right eye and doctors in my country didn't give me any hope or solution about that, please doctor or anyone else who know something about this treatment no doubt that i'll travel for that I would like to get info on any types of this treatment available ( dhia.bedoui@hotmail.fr )

  27. RAJESH BAHL RAJESH BAHL India says:

    My daughter has Amblyopia in the right side eye. She is 17 years now and had gone through the path treatment when she was 6-7 years of age. She could not follow this treatment in proper way. She has squint in the same eye and Doctor says she can go for squint surgery for correction but the vision remains minimal with -20 number.

    Please advise if there is any possible treatment any where in the world through which she can have improved vision in the Lazy eye.

    As it is very difficult to see with the lazy eye the thought of something happening to the good eye scares us.

    Please advise in case this kind of treatment can work for my daughter.

    Lazy eye treated well with playing of video games on ipad: my son 12 year was detected with lazy eye in left eye while right eye was normal. First doctor put glass after 3 month of wearing glass there was no change  eye sight. Then he put him on complete eye patch and glasses for 12 hrs a day and recommended some games like pass thread from pearls, drawing etc for 1-2 hrs a day. suddenly i read ur article but could not get special eye glasses.  Then i decided to buy his an i pad mini. and asked him to play different games and he played for at least 6-7 hrs a day while wearing patch and glasses. After one month we doctor..he asked us whether he played games he told and wore eye patch...we said no games as u told but he played video games. Doctor was annoyed and said nothing will happen. Be serious. But when he checked eye sight my son could read upto 7 lines ...a 6 line improvement. doctor was astonished to see this.. and continued the patch for another month...and we hope for more improvement....aman gupta +919815481547 india

    Everyone posting here, including myself, is interested in finding this treatment and would appreciate any information you can provide. I'm already disabled with unrelated chronic pain. If my healthy eye is damaged or otherwise loses vision, I'll also be blind. Give me a reason to hope.

    I'm interested in information about clinical trials.

    • Gwynfryn Thomas Gwynfryn Thomas France says:

      Isn't it frustrating that, after all this time, none of these doctors have thought of providing a link, it seems (this is my first visit)?
      I saw another video which claimed amazing results from a machine by Oculus (if memory serves; I’ll look it up) but I hope they provide them on lease, as I’ve no desire to pay for an expensive gamer I’ll have no use for other than improving my vision!

  31. arezou mh arezou mh Iran says:

    My name is Arezou Motamed Haeri, I had amblyopia as a child and it was because of genetic problems. My parents found out when I was 8 and mostly the ophthalmologist indicated that it cannot be cured.But at last 2 of them expressed that the problem can be cured and I started to do the treatment and at the age of 10 it was really gone and my physician told me that there is no need to even wear the glasses but now at the age of 31 another ophthalmologist recently told me that I still have the problem. either it`s not gone at all or it`s back after too many years which I think is impossible.  Now I just have some questions ; what will happen to my left eye which still has the problem? Am I loosing it ? And is there a way to have my vision back again,even by having amblyiopia or there is no way and I will get worse?

    Hi

    I hope that can be helpful....

    you can download the Lazy Eye Tetris application here
    http://lazyeyetetris.wordpress.com/download/

    Notice; I just saw this comment in some website, and I brought it to you guys that means when you are going to try to do this kind of practice you should put into consideration that your responsibility.

    Finally, I just want to remind all of you guys who have the amblyopia that at least we can see and feel the beautiful moment. However, there is people do not have the ability to see anything. Therefore, we should say thank you  god ( Allah ) for everything.

    Best wishes.

    Dear professor Hess and amblyopia- suffering people.

    I am from The Netherlands, living in Germany,  and 49 years old. My lazy eye was discovered when I was 3 years old. I wasn't patched or for a short time. Can't remember precisely. I have a amblyopia caused by a different thickness of my left and right eye lenses. I have also hyperopia, astigmatisme, presbyopia according to the latest measuring and a strong brill prescription. I have no double vision,  my right eye surprises my left. To avoid to become worse I am very interesting in vision therapie and would like to know if the amblyopia app-treatment available is somehow?

    If any of you have tried this, how well it worked, and how one obtains the device? I hope it's available for rent, as I've otherwise no use for an expensive gaming machine!

    I am not diagnosed with amblyopia, but I do have a lazy eye. I still can see out of both eyes just one at a time. I can actually switch dominant eyes and it changes on its own day to day. It is annoying when talking to people and they ask me waht i was looking at. So I am very interested in treatment.

    Please help, I am 53 and have had a lazy righty  eye since early childhood. Patching only helped for a short time and now as I am getting older my squint is getting worse, especially if I try an look at something a distance away, it is not as noticeable when you are close to me. I no longer look at people in the face or eyes when I talk to them, I walk around with my head down so no-one notices my squint, I am embarrassed to have any photo's of me taken as it is very noticeable in photos of yourself. Please can you help? I have been offered surgery to correct it cosmetically but I have  been told that I must be awake during it and I just couldn't stand it, I'm very squeamish when it comes to eyes. I am at a kiss, please help, thank you.

    Hello , I have lazy eye and at age 25 that I discovered when I did the tests to enter the security forces , something that could not get of course now I have 28 years. My lazy eye is the left , I see about 10 %, and the use of computers and glasses still the right is beginning to break to get tired and worse .. If there is treatment even if it is experimental, would like to offer me and try to correct , minimal use is certainly better than what I see with my left eye , would like an opinion and answer , thank you.
