Otis-- where are you?
Why do you always disappear when its time to answer the hard
questions?
Tell us about your results. No anecdotal stories, or quotes from
famous researchers whom you claim to know but really don't. No
putting words in anyone's mouth about "box camera model" or "static
eye" blah blah blah. Just tell us the results of your study which
shows that -3 diopter lenses cause humans to develop myopia.
What journal have you submitted it to?
.. . . . . .
.. . . . . .
ah . . . Otis? ... are you there?

No, you disagree with studies that compared children wearing glasses with
children who don't. They got nearsighted at the same rate.

Fraudulent assertion. You have not run any tests. Instead, you ignore the
scientific tests that HAVE been done.

Fraudulent assertion. -3 myopes who wear lenses do NOT become -5 myopes in
less than six months. When you claim that they do, you sound foolish.

really? please tell me about the scientific test that you ran. you
said that you ran it so tell me how you set it up and tell me the
results.

I don't want to hear you rehash an old scientific study run by
somebody else on lenses sutured full-time to a monkeys eye (which by
the way is animal cruelty). I want to hear about tests YOU ran (just
like you said) on humans. Excessive minus lenses HAVE been applies to
human eyes and found to have no effect. Its published. Please tell
us YOUR results.

I know what is dynamic about the human eye. You don't.
One thing is for sure-- your brain is not dynamic. you are unable to
read scientific studies and understand their consequences and
limitations.

really? what is proven about the human eye that supports your opinion
(not called the second opinion, but really Otis' personal opinion)?

p.clar thanks for the update. I have read some of Otis' post in the
past, but never had a direct confrontation with him. Thanks for
bringing me up to speed. I would have to agree with you regarding
RGPs :-), but you can't altogether discount them as a posibillity
dispite poor first impressions. However, you are probably correct in
that RGPs are considered after SCLs. But hey, I'm still a student, we
are a little more optomistic in the educational rhelm.

Thanks,
odtobe

Otis Dear,

I don't subscribe to the notion that anecdotal "evidence" as a
scientific proof, but since you do, here is one:

I got my first eyeglasses when I was 13. They were -1.5D for each
eye. I did not use them full time, only when I needed to see afar. I
read and did my homework without glasses. My myopia was not cured,
and in fact increased. Eventually I wore them almost full time. I
had a friend with a similar condition, although she resisted her
glasses longer than me (for vanity reasons). Would you suggest that
both I and my friend were mutants and the exception to your theory? I
must admit that I never used the "plus" because I could read fine
without glasses.

You ignored my previous response to your messages, perhaps you can
respond to this one?

Here are the scientific facts, RESPECTING the natural
eye as a dynamic system:

http://www.geocities.com/otisbrown17268/FundEye.html

I am certain you will invent "stories" to "explain away" these
direct scientific facts, to justify your majority-opinion.

But that is exactly why there is a honest second opinion
stated at:

www.chinamyopia.org

Scientific honesty would perhaps help the parents
understand the necessity of insisting that their children
keep their NOSE off that page. That would be
the first step in a PREVENTIVE program.

But I truly admit how difficult it is to PRY a child's
nose off that page. In fact he induces this negative
refractive STATE by actions of that nature.

Best,

Otis

Dear Majority-opinion PClar,

- quote -

> From long experience with ODs and MDs, I learned to
RESPECT the second-opinion regarding the minus.

I understand how EASY it is to impress a person with it.

Be equally, avoiding the minus has a long history.

Here is a recommendation by Dr. David Guyton,
about avoiding the use of the minus:

"For my young patients with simple myopia, I suggest they
leave their distance glasses off while reading, something I have
always done myself. A child who cannot see the board at school,
for example, should wear glasses to see the board, but remove them
when reading a book or writing."

You keep on insisting that the minus "is perfectly safe", and
that is your OPINION. I happen to disagree with your OPINION.

You tell me that a -3 diopter lens has NO EFFECT on the
refractive STATE of the fundamental eye. I take your
word -- but I run the scientific test.

In fact, when you place a -3 diopter lens on the eye, it will
respond by changing its refractive STATE by an averge
of -2 diopters in less than six months.

So the subject remain a matter of your BELIEF that a population
of natural eyes are NOT DYNAMIC, and the minus is "perfectly safe".

Sorry you are disconnected from the second opinion regarding
the proven behavior of the natural eye.

Otis

yes indeed otis! I agree whole-heartedly. if you try to stand-up and
lay claim to Keith as being an example of "plus prevention" then you
must also stand-up and provide an explanation of why is DIDN'T work
for your niece who became myopic despite your treatment! the reason
for your niece's failure is that refractive outcomes are not affected
in the least by using plus lenses. that result has been proven in
multiple scientific studies which you seem to ignor. i'm sure you'll
think of some kind of bullcrap excuse, or perhaps you'll just refuse
to address the question like you always do when you are proven wrong.
a real scientist wouldn't do that, and indeed an honest objective
person of any professional background wouldn't do that-- but Otis
Brown does. that speaks volumes about your character.

hello odtobe! perhaps you are not familiar with our resident troll
Otis Brown, engineer.

Otis believes he is an expert in physiological optics and
myopiagenesis even though he has no training, research, or clinical
experience in the topic. he claims that he has gained insight into
these topics because of a life-long involvement in the field which
includes friendships with many experts. in fact, when you check up on
his claims by talking to some of these so called "friends", like Dr.
Ted Grosvenor, they have never heard of Otis Brown and furthermore
they do not believe in any of the outdated concepts that Otis adheres
to. curious, is it? Otis likes to name-drop. perhaps once these
experts studied the possibility that plus lenses might reduce
accommodative strain and minimize myopia development, or that
excessive minus lens prescriptions might increase myopia, but being
objective men of science they have discarded that theory because it
was disproven decades ago. But Otis is stuck in the past and will not
accept the pile of research data that clearly demonstrates that myopia
development is a little more involved than his simple-minded scheme.

And when you confront Otis with straight-out scientific proof that his
theory is wrong he ignors you or either he instead offers an anecdotal
story about "Mike" or "Jane" or some such other person he has talked
to that relays a personal story that for some reason he holds in
higher esteem to real objective scientic studies. in the past, one of
his so-called personal success stories actually saw what he was
writing and confronted Otis on this newsgroup. He relayed that Otis
was misrepresenting his personal experience as proof that plus lens
therapy actually worked in his case when in fact the opposite was
really true-- his myopia persisted.

yet still, despite public humiliation, otis fights on. he is nothing
if not persistent. he tries to describe a difference between
"medical" scientific studies and "engineering" scientific studies that
is puzzling and ridiculous.

as clueless as Otis is he is actually a kind of fixture around this
newsgroup. don't try to reason with him-- his mind is made up and he
doesn't want to be confused by the facts.

actually I am not in complete agreement with this statement. many
patients with this low level of astigmatism don't really notice a
significant improvement in their VA when you correct their
astigmatism. the patient may achieve 20/20- with a spherical
correction and get only a slight boost from additionally correcting
the cylinder component. sometimes that boost is visually insignificant
to the patient. -0.75 cyl just isn't that much.

and it is obvious that RGPs are going to be less successful than
disposable SCL. not due to any optical considerations but due to the
fact that 80-90% of patients who first put in an RGP and not happy
with the comfort of the lens regardless of whether they can see a
sharp image or not. trying to fit such a patient in an RGP is a good
way to ensure that the patient will not return to your office for
their next appointment, or for any appointments, in the future.

in this case I would usually give the patient a trial pair (disposable
SCL) of spherical lenses and a trial pair of toric lenses and ask them
to compare them at home for approximately a week and then return to my
office for a check appointment wearing their favorite pair.

this is just my way of doing it, and what my personal experiences are.

cheers.

I'm sorry Otis you're right, information is free and good to give the
patient. But I was under the impression that a DOCTOR has a liscense
to practice medicine. Shouldn't doctors be in the habit of providing
solutions that are going to be the most benifetial to the patient?
Also this person is a rather poor CL candidate, at least for softs.
Might think about RGPs if the K's look correct, but the SE for a spec
lens just doesn't make any sense. They have already chosen the
cylinder lenses in the "SUBJECTIVE" portion of the refration, that's
generally how an RX is finally determined. I understand that giving a
person the SE in a sphere SCL would be nice, BUT NOT IN THIS CASE.
