Today's Times article on vision correction in Naval Acad.
|
|
|
Today's NY Times is running an article on how the Acadamy is making vision
correction surgery available for free to middies. One impact is that since
more people have good enough vision to enter flight school, they are having
a tougher time filling other slots.

Odis> Perhaps THEY understand the average "down rate" that
occurs during those four CRUCIAL years.

Remarks by Dr. Stirilng Colgate:
My support for Steve Leung OD and Alfred Bossino
To the Parents,
I have often wondered why the profession of optometry does not change
its treatment for the prevention of myopia with a plus lens -- in these
decades after the ground-breaking scientific research by Dr. Francis
Young, Dr. Howard Howland and others has been successfully completed.
I have seen the number of young myopes increase in the USA and to an
incredible extent in the Far East. The prevalence is very serious in
Japan, Hong Kong, Singapore, Taiwan and China.
I regret this obvious and rapid increase in the degree of myopia around
the world -- because of the use of the traditional (minus-lens)
treatment. This is a primitive method indeed. To this date there has
been no systematic effort to educate the public about this method of
effective nearsightedness prevention with the plus lens.
I personally support and recommend the work of Steve H. Leung and
Alfred Han Bossino. They are making a sincere effort to educate the
public about the necessity of "correct use" of the plus lens for
prevention. Mr. Leung's knowledge and skill will be of considerable
value to your child in his goal of maintaining clear distant vision
through the school years.

Additional second-opinion remarks by Dr. Colgate:
November 20, 2004
SF_NAS.txt
To the Parents:
In the Matter of Steve H. Leung OD and Alfred H. Bossino.
Dear Sir,
I am a senior scientists, astrophysicist and nuclear
physicist at Los Alamos National Laboratory and a member of the
National Academy of Sciences of the USA. For all of my scientific
career I have been dedicated to understanding the cause of natural
phenomena. From the age of 13 years, now 66 years ago, I
recognized that the standard response to myopia was perhaps miss
guided. Instead I used positive lens glasses to correct, or alter
my focal environment, namely one of reading nearly all the time.
(A positive lens "corrects" a near-point focal environment by
altering the light rays to be more parallel from the near-point
object. as if the print were made more distant.) Being young and
therefore developmentally plastic, my eyes and their focal
properties immediately responded. Within just a few weeks, the
clarity or focus of distant objects had been restored. This was
just as I expected from scientific arguments. I had to maintain a
positive lens for reading thereafter. This was a small price to
pay for perfect distance vision for all my life.
I have continued an effort to bring this awareness of the
focal adaptation of the natural eye to the public, but
unfortunately the ease and immediate response of the standard
treatment of using a negative lens to reverse the myopic
adaptation to a near point environment is so immediate and so
rewarding to the myope that I and a few associates have not been
successful. This is regardless of the decades after the ground
breaking scientific research by Dr. Francis Young, and Dr.
Howard Howland and others.
I have worked scientifically with Prof. Joshua Wallman of
City College New York where his research on the response of the
natural eye to focal and neurological environments is leading the
fundamental research on this topic in the US. The animal model
used is the recovery function of the deprivation induced myopia of
the chicken eye. Here myopia and recovery can be altered by 10
diopters in a few weeks. This extreme animal model allows many
factors of influence to be investigated in a short time. Although
the complexity of the response of the eye is extraordinary and a
detailed understanding of the mechanisms still eludes all in the
scientific field, nevertheless there is no experiment, no
anecdotal example that contradicts, and no doubt in my mind that
myopia in all animals, including humans, is induced in response to
a near point environment.
In view of this research and countless personal successful
examples the growing number of myopic individuals in the world is
deplorable, when such a simple remedy is available to the public.
Steve H. Leung OD is a dedicated optometrist who has
taken a lead in attempting to bring this knowledge and
benefit to their patients.
For them to be persecuted within his own professional
societies is wrong. He should be lauded and encouraged instead.
I am reminded of the first health professionals who spoke out
about the health problems that smoking brings to a society.
Theirs was a difficult task, but now thirty years later, smoking
in the US has declined to a negligible fraction of society. If
we, as a culture, can give up smoking, we can also be weaned from
the negative lens.
I do hope and recommend that you strongly support what these
dedicated optometrists are bringing to your profession.
Sincerely yours,
Stirling A. Colgate Ph.D.

Second-opinon PREVENTIVE remarks by Dr. Francis Young:
Professor Emeritus at Wshington State University, Dr. Young is also a
recipient of the AOA's prestigious Apollo Award, as well as ten other
honors in the optometric profession. He has authored or co-authored
more than 100 research papers, and his groundbreaking research with
Native Alaskans in 1968 provided powerful evidence that nearsightedness
might not be inherited and could potentially be prevented. He is a
graduate of Ohio State University.

You missed the three or four decades where we DID use plus to prevent
myopia. Funny how you can ignore that.
It didn't work so we quit.

And you think they all got that way from wearing glasses. They didn't.

Because it doesn't work. You haven't shown that your treatment works.

So maybe one of those learned experts will publish a report showing that
your therapy is effective.
Maybe not.

I wonder why Dr Sterling Colgate does not check the literature. Vision
researchers have tested whether plus lenses work to prevent myopia for
the past twenty years and found that it doesn't work. The reason why
clinical optometrists do not recommend the plus lens is "IT DOESN'T
WORK".
Perhaps he should also check out Dr Howland's more recent research, in
which he finds that wearing minus lenses does not result in increase in
myopia in chicks, that different genetic strains of mice and chicks
vary considerably in their eye growth response to myopic and hyperopic
blur, that reading does not result in sustained accommodative spasm
when reading stops, that wearing plus lenses during reading does not
result in decreased accommodation during reading and that accommodation
is really not much of a factor in myopia development. Find them all on
PubMed

Shall we look at what Prof Wallman has to say about myopia?
Here is a quote from an review he published in Neuron in 2004
"Related to this, there has been a view, which has existed on the
margins of science for decades, that most myopia is iatrogenic, in that
the eye doctor, instead of letting the myopia stabilize at the level
that brings the page into focus, corrects the vision with negative
lenses, which reimposes the original error that caused the myopia in
the first place (Medina and Fariza, 1993). Needless to say, this idea
has not been explicitly tested, as that would require randomly
assigning some myopic children to be uncorrected, a procedure unlikely
to be tolerated by parents or institutional review boards. A more
modest test of this hypothesis was to undercorrect the myopia of
children. Several small studies found undercorrection to reduce myopic
progression (Goss 1994 and Ong et al. 1999), but in a recent, larger
study, undercorrected children showed greater, not less, myopic
progression than those who were fully corrected (Chung et al., 2002)."
So he has looked at the literature and debunks the idea of staircase
myopia.
And in the same review he discusses reading and suggests that if myopic
blur is induced by reading that it should help prevent myopia, ie
reading with plus lenses to prevent myopic blur would be counter
productive:
"In light of the work discussed above concerning brief myopic defocus
canceling the effects of long periods of hyperopic defocus, we would be
inclined to the opposite interpretation, namely that brief myopic
defocus after each period of reading would protect the eye against
myopia."

I have had a number of post-LASIK patients in the uniformed services
and law enforcement consult me concerning night vision issues. Their
concern is that the presence of halos and starbursts may impair their
night vision performance. I don't recall seeing this issue raised in
the article.

But, of course, if you love seeing your kids develp stair-case
myopia from the minus -- as these 85 percent has done it -- then
go ahead.
4) Goh and Lam (Goh, W.S. and Lam, C.S., "Changes in refractive
trends and optical components of Hong Kong Chinese aged 19-39
years," Ophthal. Physiol. Opt., 14:378-382, 1994) found that
in 2000 first-year students at the University of Hong Kong,
the prevalence of myopia was 87.5%.
The evidence is that this situation could have been PREVENTED
at the threshold.
But that is the nature of your choice -- as suggested by
Francis Young and Stirling Colgate.
Just be wise in choosing a prevention-minded OD to
HELP YOUR KID, before the situation gets out-of-hand
with an over-prescribed minus.
See:
www.chinamyopia.org
for details on the preventive method.
Best,
Otis
