Talk:Amblyopia

message: It seems like a tough question whenever one wants to answer precisely (is it more 1% or more 5%) because it depends on the country, the age, and mostly the criterion chosen (one line, two line difference? including all amblyogenic causes or not?). However, when one is claiming that it is between 1 and 5%, ALL studies agree (in western countries). So I don't think so we can go wrong on this one. They agree no matter what is the age or the criterion, but the range can go to 10% when including non-western countries. 
Secondary sources:
*GHS study (we cite)- review different age, countries, criteron, ranging from 1 to 10% - 10% being in non-western countries). The study itself finds 5.6% in Germany (adults 35-44).
*Birch's review (2013): review studies ranging from 1 to 3.6%, all in children, average 2.4%
*Flom and Neumaier (1966): review studies ranging from 0.6 to 4% (excluding clinical samples), various population, age, but all in western countries.

thread_title: Prevalence for amblyopia

message: It was quite ironic that Amblyopia is one of the very few diseases that is not tamed enough by the human intelligence.  It almost goes unnoticed at the very age of the victim, when it can be best controlled. It is good that children are lucky enough to have wonderful treatment regimens available to them these days, if only, when detected in time, that is in their very early years, but the stigma and pain that is associated with Adult Amblyopia is particularly unbearable. I came to know that I am one of the very few people who fell to this seemingly innocuous disease(rather poor vision condition - doctors won't give up to call it a disease)  when I was first disqualified in 'Army Selections'.  That was a blow to my career as I always dreamt of becoming an 'Officer in Uniform' right from my childhood.  Then started my ordeal, it forced me to change my goals, take up unplanned ventures, constantly irritated me now and then, and more than anything else, I am very much depressed to imagine the fact that one day I will become a one-eyed jack.
While it is extremely painful to learn that there is no proven treatment for the adults, the plight of the people like me in the still developing countries is un-imaginable, where nothing is being done effectively, even the diagnosis of this bloody disease( let me vent my anger). 
My Dear Brothers Of The World Who Are In The Same Boat With Me:  We share the slogan with the victims of the most dreaded disease(or ???condition) on this earth AIDS:
DOCTORS OF THE WORLD: DO SOMETHING AND SAVE US before it is too late.
:This seems rather over-wrought. I have had amplylpia since early childhood, did the patch thing without any results, and have lived with it since age 5, now I am 60. Other than in a few situation involving hand-eye coordination, it has never been a bother. Unfortunately (IMO), it did not keep me out of the Army, infantry, or Viet Nam.

Did the patch thing as a child, tried a contact lens for a while (no noticeable difference, and while there were very slight improvements I did not feel it was worth it).

message: Does Amblyopia have anything to do with Ocular Dominance?
Ocular Dominance Wikipedia link: http://en.wikipedia.org/wiki/Ocular_dominance
Amblyopia has a lot to do with ocular dominance, though not necessarily in a clear-cut way.  Monocular occlusion during development is a well-known way to cause amblyopia, and causes the ocular dominance columns of cortex for the dominant eye of the amblyope to dominate that of the amblyopic eye.  Behaviorally, amblyopia - which has a poor medical definition - exhibits symptoms that suggest information loss in transmission from eye to cortex because of poor development.  That information loss could be caused by the mechanics of the screwed up distribution of ocular dominance cells, which extends in a loop from the eye through the lateral geniculate nucleus, and into the cortex, as well as into the pons which controls certain automatic tracking activities.<spetz>.216.175.188.98 22:17, 28 February 2007 (UTC)
replies: text: The medical textbook definitions of amblyopia might be poor (agreed) but from research in the last twenty years (e.g. R. Sireteanu) we have a reasonably good understanding of the phenomenon. Yes, as a yardstick, it has to do with the ocular dominance cells, but to clarify the above they are located in the primary visual cortex (first characterized by Hubel & Wiesel), not in the lateral geniculate nucleus (but perhaps I misunderstand the above sentence). Strasburger (talk) 10:50, 17 January 2014 (UTC)

text: Perhaps I am missing something, but amblyopia and ocular dominance appear to be two POV and therefore unscientific ways of designating the same phenomenon(?).  —Preceding unsigned comment added by 83.138.172.76 (talk) 22:09, 17 July 2009 (UTC)
replies: text: Amblyopia and ocular dominance are different scientific concepts and refer to different phenomena. They are not independent of each other (e.g. amblyopia in one eye might be the reason for the dominance of the other), but so are many things. Strasburger (talk) 10:50, 17 January 2014 (UTC)

message: Amblyopia is not "lazy eye".  Strabismus is.  I have strabismic amblyopia.  That is, as a child my strabismus (now cured) led to amblyopia (not cured).  I have not had "lazy eye" since my childhood even though I still suffer from amblyopia.  I thus suggest that the appositive , or "lazy eye", be removed from the article's first sentence.

replies: text: I'm afraid I disagree. Although hardly used by clinicians, the term "lazy eye" refers to amblyopia, which may be caused by strabismus. It is a common misconception that "lazy" = wandering = strabismus, but "lazy" in fact refers to "weaker" or "suppressed". The fact that the two often occur together propogates this confusion.

message: Let me explain why I wholesale removed the section on prozac as a potential "cure"...
This is one study. And its in mice not humans. And it involves a drug. And this drug has recently been shown to not really have any great antidepressant effects. That means that producers of prozac could potentially be losing their "depressed kids" market and may be scouting about for some other group to sell it to. 
Finally, and most importantly, I would feel pretty bad if, based on this flimsy evidence, amblyopic kids started taking Mum's prozac because they didn't like wearing a patch for two hours a day. I suggest we let scientists do their job and test this hypothesis before proclaiming it as a new "cure". The jury is very much still out on this one. One swallow does not a summer make...

replies: text: Okay, firstly, calm down. You're right, there currently is no cure (if you are older than mid-teens) although there are some promising avenues of research. Lasik won't help because the problem is not in the refractive properties of the eye, but in the brain (it should be called "lazy brain" ;-) ). But you're totally wrong about it being "immensely underrated (and) understudied." I know of labs and researchers all over the world who take amblyopia very seriously and have made huge leaps in our understanding of what goes wrong in the brain to cause the condition. It helps to understand a condition before you can develop an effective cure, so this is all useful info. You also suggest research into it is underfunded, but that's not the case. Lots of money is thrown at this problem by research councils, but money may not be the issue - the intractability of the problem is. If you want to volunteer for research studies into potential treatments I can put you in touch with several labs. Send me a private message. And calm down.

message: Looking at the treatment and prognosis section where it talks about the Enfant system, the tone does not seem to me to be encyclopedic - the section only discusses the drawbacks of the conventional detection method, and the pros of the Enfant system, using terms like "breakthrough technology" and a list of features of the system which does not seem to be appropriate for an article about one of the conditions that the system detects. While it may merit a mention on the page as a detection method, with some reasoning provided, I think this might warrant a rewrite (by someone more knowledgeable on the topic than myself, probably).

thread_title: Addition to research subheading

message: It is written that: "In amblyopia visual stimulation either fails to be or is poorly transmitted through the optic nerve to the brain for a continuous period of time"
This can be understood as if the cause of amblyopia was in a problem of optic nerve. This is obviously false. There is no research backing up this claim, while there are thousands of papers showing this has a cortical cause (and the debate is rather about the pure implication of V1 or of other areas, like extra-striate visual areas or LGN: see Levi (2013) for a review). This is important to correct that, given I have seen the error spreading in non-academic websites or translation of the wikipedia webpage in other languages. This is going to far and it is time to stop the bleeding.
I think the original intent of the sentence is to explain that whenever the brain does not receive visual stimulation for a continuous period of time, there is a risk for amblyopia.
I am open to discussion, but there is a consensus in academia on that so there should be none.
