As the ophthalmologist thread has been subverted : )

There was an interesting Medscape article today, talking in general terms
about how to improve diabetic control. Page 3 of it, however, was very
interesting wrt the discussion we've been having about the time it should
take for newbies to go to normal levels. They're not talking any specifics
about retinopathy here, but I wonder if it would kill 2 birds with one
stone! Incidentally, they recommend insulin for a newbie with an A1c>9%.

This is the bit that specifically caught my eye, though:

Recommendation 6: Treat patients intensively so as to achieve target HbA1c <
6.5%2within 6 months of diagnosis.

Interesting.

But it doesn't sound like the 6 month time period suggested here was
chosen with any thought as to the safety or non-safety of lowering blood
sugars too swiftly or a fear of causing retinopathy.

The authors are mainly arguing against the common practice which is to
leave patients with blood sugars in the danger zone for a few years
while putting them on this and that drug that don't work very well.
Suggesting control be attained in six months is meant to be a "hurry up!"

Looking at the references, the only reference to retinopathy is an
article explaining the DCCT discovery that lowering the A1c cuts down
significantly on the risk of retinopathy, which is cited in the article.

Indeed, I doubt you will find any serious discussion of the question  of
whether retinopathy worsens in type 2s who get tight control quickly in
any practice guideline like this one.

With hundreds of thousands of people with Type 2 going blind because
their doctors never get them below 8%, the rare people with type 2 who
have mild worsening while getting better control does not seem to be
something doctors are worrying about or discussing.

The reports of worsening with gaining of tight control all came from the
big Type 1 study (DCCT) not the type 2 study (UKPDS) where no Type 2s
developed worsening when going for tight control. The few other studies
that look at the connection between better control for Type 2s and
worsening retinopathy are small, inconclusive, and have serious design
flaws. None of them comes up with a recommendation of a "safe" time period.

And it is worth reminding ourselves that the DCCT data did not show any
difference in worsening between those who gained quick control and those
who gained slow control. Indeed, the DCCT statistics suggest that the
worsening comes from getting control after being very high, period,
regardless of the time involved.

Beyond the analysis of the DCCT data, where they did look at speed of
gaining control, there is NO study that looks at different speeds of
gaining control and plots that speed against retinal worsening.  Period.
The studies only show, incontrovertibly, that in a very small percentage
of people, worsening occurs when control improves.

I feel really bad that Chris has to go through what he is going through,
but nothing he has posted goes beyond the anecdotal and it is likely
that it may, when all is said and done, relate to people with blood
sugars near 600 and massive infections with long histories of drug and
allergic reactions who have some really, really bad luck.

If you really are interested in this question, you might email the
doctor who published the journal article (there always is an email
address included in the actual article) and ask whether he'd advise
against getting control more swiftly because of the retinal issue.

Agreed that they aren't discussing it, but they darn well should be,
as it's nowhere near as uncommon as any of us had thought. It even has
a name: Normoglycemic re-entry retinopathy.

How can you say that conclusively? I haven't been able to find one,
but that's not proof it doesn't exist. I intend to keep looking.

Would that include my retinal specialist stating, explicitly, that
slower lowering is better? I don't see how that is at all anecdotal in
this context.

That is an excellent idea! Thanks.
And BTW, so far both my retinologist and opthamologist have said
"slower would be better", and I'll try and get them to specify a
timeframe.

Because when the ophthalmologists who have published the most on the
topic of diabetic ophthalmology published a comprehensive review of the
literature on the subject in 2004 in Diabetes Care, the premier journal
covering treatment for diabetes (an article citing 134 research papers)
they cited no such study.

The authors on this review are researchers with a huge presence in the
field. Do a Google Scholar search on authors Donald Fong or Ronald Klein
and you'll see what I mean.

Diabetic Retinopathy
Diabetes Care 27:2540-2553, 2004
http://care.diabetesjournals.org/cgi/content/full/27/10/2540

They did say, discussing the DCCT data (the only major study to come up
with data on this topic:

"Analysis for early worsening was conducted and noted to be present at
the 6- and/or 12-month visit in 13.1% of 711 patients assigned to
intensive treatment and in 7.6% of 728 patients assigned to conventional
treatment (P < 0.001). By the 18-month visit, there was recovery in 51%
of the intensive and 55% of the conventional groups (P = 0.39). The risk
of three-step or greater progression from the retinopathy level present
18 months after entry into the trial was greater in patients who had
previously had early worsening than in those who had not, but there was
a large long-term risk reduction with intensive treatment. Patients who
developed early worsening as a result of the intensive treatment were
similar to or had more favorable outcomes than those in the conventional
group who did not have early worsening. Analysis did not suggest
reduction of early worsening with more gradual reduction of glycemia."

PLEASE NOTE THE LAST TWO SENTENCES

> Would that include my retinal specialist stating, explicitly, that

> this context.

Yes. This is anecdotal, as is Wendy's distinguished retinologist telling
her the exact opposite.

In scientific terms "anecdotal" means "what I am concluding based on the
stuff I've personally seen, as opposed to what large, well conducted
studies have been able to document in ways that hold up to subsequent
analysis of study design and which can be validated by reproducing
results."

These retinal specialists are in the field doing the laser coagulation
and treatments. They aren't researchers setting up experiments or
analyzing data. So their opinions are formed by what they see in their
office which is only a small segment of the patient population. And if
they are anything like the retinal specialist I worked for many years
ago, most of their very sparse spare time is spent reading up on new
surgical techniques and practicing them on sheep's eyeballs in the lab
not reading up on the causes of the conditions they treat.

> And BTW, so far both my retinologist and opthamologist have said

When you do, be sure you ask them what they base their recommendations
on. Have they seen research that supports that conclusion or is it an
educated guess?

I have found with my doctors, that they don't like to admit they don't
know the answer to something. So If you ask them a question, they often
will state things with great certainty which upon further examination
turn out to be opinions not fact. (And in my case, turn out to be
completely different than what labs turn out to show.) That's why it is
always a good idea to ask what the basis is for a statement that has
great importance to you.

OK, thanks, I did not know that, but I'm going to look for that
online, or, failing that, order a copy.

However, I'm still going to keep looking, as it's at least possible
something was missed. You had to did very deeply and not give up in
order to find some of the data on your website, as I recall, so I'm
not giving up either. I learned long ago that it's darn hard to prove
a negative, and just because I can't find it does not mean it does not
exist. Don't worry though, I'm sure not going to base any advice on
something I can't find!

circumstances for a T1 at DX are quite different in this regard:
mainly, they are quite unlikely to have had sustained high BG's for as
long as a T2. There are also seem to be (not sure yet) differences in
the IGF-1 profile.

Also, why do you say the DCCT is the only major study? The article you
cite cites both, and so I thought the UKPDS (a T2 study) would also
qualify? And what about the following
Henricsson M, Nilsson A, Janzon L, Groop L. The effect of glycaemic
control and the introduction of insulin therapy on retinopathy in
non-insulin-dependent diabetes mellitus. Diabetic Med 1997;14:123-31.
http://tinyurl.com/pacyg

I can see, though, why it wouldn't be considered a major study.

However, please note the last line
"In conclusion, while hyperglycaemia was a risk factor for the
progression of retinopathy in all patients, change of treatment from
oral drugs to insulin was associated with a 100% increased risk of
retinopathy progression and a 3-fold increased risk of
blindness/visual impairment."

A 3-fold increase of risk is a rather significant finding IMHO.

I'm well aware of them. But, this is far from conclusive. It's a T1
study, and "analysis does not suggest" is hardly a definitive outcome.

Sorry, but IMHO, the jury is still out on this one.

That's a very good point, and I'll make darn sure I ask that.

ARGH! I've run into that with both Docs and other professionals. I
have however observed a different response: they avoid a direct answer
until pinned down. I've learned to assume that if they don't answer
directly, they probably think they are on shaky ground.

The reason that DCCT data is cited is that it is the only large scale,
long term study that found worsening and analyzed enough data to come to
conclusions. The UKPDS is the other corresponding study of Type 2s, but
it did NOT find evidence of retinal worsening in it's population though
they made the same dramatic decrease in blood sugar levels.

There are a few, much smaller studies of worsening in Type 2s put on
insulin (your cite might be one of them.)  Bbut one of the articles I
cited for you back when you first posted (and don't have at hand, though
the message is still out there and should be able to be found via
Google) included a review of several small studies that found worsening
in Type 2s put on insulin.

If I recall correctly, that review explained that the problem with these
studies was that the patients put on insulin in these studies were
typically those who had been out of control for many years who were only
put on insulin, very late, as a last resort. So there was a huge
question as to whether their retinopathy was already pre-existent due to
the decades of high blood sugar exposure. These after all, were patients
whose A1cs had been over 10% for many years.

Here's another relevant article for you from Medscape where the question
is asked of experts from Joslin & Harvard Med School. They pretty much
say the same thing as the Fong article, but they said it in 5/03. I've
included most of the text for your convenience. Follow the link to see
the references.

Does Initiating Intensive Glucose Control Worsen Existing Diabetic
Retinopathy?
Question

Some endocrinologists in Japan state that controlling blood glucose
levels too quickly in patients with severe diabetic retinopathy can
worsen retinal lesions. Is there any evidence to support this statement?

Response from Lloyd Paul Aiello, MD, PhD
Assistant Director, Beetham Eye Institute, Joslin Diabetes Center;
Associate Professor of Ophthalmology, Harvard Medical School, Boston,
Massachusetts

Jerry Cavallerano, OD, PhD
Assistant to the Director, Beetham Eye Institute, Joslin Diabetes
Center, Boston, Massachusetts

The Diabetes Control and Complications Trial (DCCT) definitively
demonstrated that intensive control of blood glucose levels in patients
with type 1 diabetes mellitus substantially reduces the risk of onset
and progression of diabetic retinopathy.[1,2] In addition, the reduced
risks of onset and progression of retinopathy associated with intensive
therapy persisted at least 4 years beyond the conclusion of the DCCT,
despite near convergence of hemoglobin A1c levels in the
intensive-therapy and conventional-therapy groups.[3]

The United Kingdom Prospective Diabetes Study (UKPDS) found similar
benefits of intensive blood glucose control for patients with newly
diagnosed type 2 diabetes.[4] In the Kumamoto study in Japan of patients
with type 2 diabetes who were taking insulin, the benefits of intensive
control of blood glucose levels were likewise demonstrated.[5]

The DCCT documented "early worsening" of diabetic retinopathy in the
study population.[6] Early worsening of retinopathy was defined as a
3-step or more progression of retinopathy on the severity scale, the
development of cotton wool spots and/or intraretinal microvascular
abnormalities, and "clinically important retinopathy" if it occurred
between baseline and the 12-month follow-up visit. Early worsening of
retinopathy occurred in 13.1% of 711 patients assigned to intensive
treatment and in 7.6% of 728 patients assigned to conventional
treatment. Nevertheless, after 18 months this early worsening in
retinopathy reversed, and patients in the intensive-treatment group
fared better than those on conventional therapy. Risk factors for early
worsening were higher hemoglobin A1c level at baseline and reduction of
this level during the first 6 months following randomization. There was
no evidence that a gradual reduction in A1c levels reduced the risk of
early worsening.

In the DCCT, the long-term benefits of intensive control clearly
outweighed the risk of early worsening of retinopathy, and no case of
early worsening resulted in serious visual loss. Based on these
findings, it is recommended that persons with type 1 or type 2 diabetes
initiate intensive therapy as early as possible, and maintain intensive
therapy for as long as possible, with the expectation that intensive
control of blood glucose levels will reduce the risk of onset and
progression of diabetic retinopathy. For patients with elevated
hemoglobin A1c levels, careful retinal evaluation, close retinal
follow-up, and laser photocoagulation as indicated are important
components of care as intensive therapy is initiated.

And those conclusions are slightly questionable for T2's under these
circumstances. I'm not saying they are wrong, only that I can't see
them as being definitive or proven.

>The UKPDS is the other corresponding study of Type 2s, but

That I think depends on one's definition of dramatic. The studies
involved A1c changes of 2 to 4 %, and made little reference for actual
timeframe. Mine went down over 7 in three months, with the vast
majority of the decline taking place in a week.

My A1c at Dx was 12.5, but my BG's at Dx were far higher than that
would indicate, probably due to my infection. However, a couple of
months before I was Dx'd, I had a full retinal exam, and no signs of
retinopathy were seen.

THIS is something I missed: It *REVERSED*!!! I had seen some other
reports of it doing so in up to 50% of cases, but this seems to state
it as an absolute.

I still say I would like to see a study done on this, as I suspect
there never has been one. Even the mechanisms for early worsening
(normoglycemic re-entry) is only theoretical at this point.

Chris,

The difficulty with the study of Type 2s is that for a definitive study
you need a very large group because in most studies Type 2s don't
develop this problem, so only a tiny number might even develop the
problem in your study. Then you need to have subjects broken into groups
and very well matched with controls and you need to have a protocol
where the speed is controlled at different speeds and the insulin types
controlled and the diet controlled. All this would be very expensive to
do, if it is even possible, and will not enrich any drug company--and in
fact might end up putting the insulin companies into a Vioxx-type
condition. So the chances of it being funded are zilch.

The other problem is that all the data shows that this is only a problem
for people with existing retinopathy. You would not even have fallen
into that group given your recent retinal exam showing no problem.

Every study I've seen shows that people with the tight control end up in
no worse shape and mostly in much better shape than those who don't
control tightly no matter what the initial worsening is. That is
probably why Wendy's doctor says go for the control.

And I still think your own situation may be complicated by a drug
reaction or something to do with the infection itself, which doctors
wouldn't be aware of.  I have never yet found a doctor who was aware
that the drug I took causes permanent tinnitus, though I have found two
other people online who have suffered the same injury from the same
class of drugs.

Yep...

Not exactly. I've seen at least one report of it occurring in 2% of
people without retinopathy, and I'm one of them.

>Every study I've seen shows that people with the tight control end up in
>no worse shape and mostly in much better shape than those who don't

OK, we might be discussing tangential issues here: Tight Control Vs.
Speed of tight control. I'm absolutely not questioning tight control.
Everything I've seen indicates tight control is the best defense. The
only thing I'm questioning is the SPEED of attaining tight control. I
think it might be that excessive speed is an aggravating factor in
normoglycemic re-entry phenomenon, but I don't know if that's true or
not.

>And I still think your own situation may be complicated by a drug

I think that's possible, too.

Same with me and lisinopril: my Doc was unaware that it can cause
tingling in the fingers and toes.

But the real question is how slow.  

I understand the problem you've had and that you want to prevent it in others.
Definitely a worthy goal!

But I can imagine the newbie coming along -- just diagnosed, doctor said "take
this pill, stay away from sugar, and test your blood sugar in the morning."  
The guy is scared, wondering if his whole life is going to change, wondering
if he's going to end up on dialysis, and then he reads "don't get your blood
sugar down too quickly."  And he thinks "hey, my doctor wasn't too excited
about this and now this guy says be careful about going down too fast.  So
I'll just keep taking that pill every day and I'll be fine."

What's really needed is a number.  You should aim to lower your BG by X points
a week or Y points a month.  Or maybe by a percentage.  I don't know if such
guidelines exist, but they would be helpful.

Tentatively, I can say that I think such a newbie would have little to
worry about in this regard, as insulin intervention seems to be a
requirement for Normoglycemic re-entry phenomenon.

They would be perfect, and that's exactly what I'm trying to find. The

G'day G'day Nicky,

Thank you.  

A couple of things have troubled me over the situation Chris found
himself in.  

Firstly since the specialist he visited most recently has stated there
is a risk associated with rapidly dropping blood glucose, why wasn't
he provided with this information on a discharge sheet?

Secondly although the latest specialist has identified a risk
associated with reducing blood glucose rapidly he doesn't have given
the relative risk of not doing so. Put simply monstrously high blood
glucose is a risk in itself.  There is a risk if one reduces them
rapidly and a risk associated with leaving them high.  It could be
that there is risk associated with rapid decreasing them of
2% ie 1 in 50.  What is the risk associated with leaving them high for
1 month, 2 months, 3 months etc?   There must be some break even point
unless the risk of leaving them high is always higher than 2%.  

Best wishes,

Yes indeed. I don't think anyone's cavilling about knocking down bgs like
Chris had ASAP. Another variable here is, what's a monstrously high bg? The
link I posted suggested an A1c of 9.5, which must be a, what, 250-300 ave
bg?

Without knowing the damage mechanism, I'm worried that there may be an
increased potential to damage at having bgs running around the 140 mark too,
or whatever an individual's retinal threshold might be, as pressure is
reduced... and increased... reduced... increased...

Yup. And how do we trade that off against the known risks of micro and macro
damage from a >6 A1c.

The problem we have is that Chris is going through a deeply bad experience,
and has a duty to tell his story to newbies. As he's articulate and
persuasive (and a moral person) it's important for him, newbies, and us that
he is able to recommend a path that's as healthful as possible - or (quite
apart from confused newbies!) we're going to have endless paths where Chris
says "watch out!" and we say "But that's a small comparative risk!". We need
to find out as close to a mutually agreed path as possible - preferably via
Chris' eye doc.

Using the formula that came out of DCCT, a 9.5% A1c relates to an
Average Plasma glucose of 261 mg/dl or 14.5 mmol/l. Since it is an
average, it could easily represent swings from 100 to 400 mg/dl.

Chris reported that his blood sugar in the hospital was 600 mg/dl 33
mmol/l which is more than twice as high. That sounds pretty "monstrous"
to me.

The "retinal threshold" for glucose is a speculation advanced in
discussions here, but has no basis in fact.  A threshold is, by
definition, a sharp cutoff. With the renal threshold, for example, there
is no glucose spilling in urine and then at the threshold, the glucose
spills.

But from what I can see scanning research on retinal thresholds, glucose
in the eye does not appear to have a threshold, but rises in a straight
line relationship with the concentration of glucose in the blood.

The 140 mg/dl number is a GTT number that correlates with a threshold
increase in nerve damage, not retinopathy.

There is NO number that has a clearcut relationship to the increase in
retinopathy, a point that was emphasized by the recent discovery that
there is a significant percentage of people with blood sugars in the
pre-diabetic range who have already developed "diabetic" retinopathy.

What little research there is online suggests that the glucose level in
the eye rises in a straight line, which is why there is some research on
using visual tests to non-invasively measure blood sugars.

But we have to remember, also that Chris' eye doctor is a retinal
specialist who sees only a population of people after they have
developed retinopathy. He is also a hands-on technician whose focus is
on eye surgery, not a specialist in the treatment of diabetes as a whole.

This means that his statement while worthy of consideration is not the
last word on the subject, any more than your cardiologist's might be, no
matter how busy his practice, unless backed up with some kind of
evidence beyond "this is what it seems to me I'm seeing in my office."

Progression of Retinopathy During Pregnancy in Type 1 Diabetic Women

found on page 874 in a 1999 Diabetes Care article -

The thresholds have both upper and lower aspects (involved is rapid BG
change that results in retinopathy problems).  The kind of insulin used
may also be a factor.

There are some aspects of diabetic complications that do involve
genetics as Nicky has mentioned.  [retinopathy+edema+genetics+diabetes -
http://tinyurl.com/mx39u or retinopathy+edema+genetics+diabetic -
http://tinyurl.com/q4sqc.] The case with Chris may seem extreme but
upper thresholds much lower than his high might also be involved.
A growth factor termed "VEGF is involved in normal angiogenic processes
in adults such as cardiac collateral circulation, wound healing and
menstrual cycle." Angiogenisis (growth of new blood vessels)is also
necessary for a cancer turmor to grow larger than a pencil dot.

"Apparently clinical trials of lispro insulin in nonpregnant diabetic
women did not show unexpected development of PDR. Lispro is a homolog of
IGF-1. The role of the growth hormone–IGF-1 system in the development of
PDR is under increasing scrutiny. Insulin is known to enhance IGF-1
production, but the effect of insulin lispro on the IGF-1
system is not well described." From the second citation above.

The articles I have cited pertain to diabetes and pregnancy which

Frank,

I did scan your posting, but it wasn't clear to me how it would fit in
as pregnant type 1s are a whole different thing from obese type 2s
metabolically, and so much weird stuff happens during pregnancy that it
is hard to tease out what anything might mean in that context. And the
edema issues alone fill many books.

It's a good point that the kind of insulin might be related, except that
the one major study documenting the worsening was DCCT done long enough
ago that they may very well have been using nothing but animal insulins.

OTOH, there's a mention of Lantus possibly being associated with
worsening of retinopathy  mentioned in the Lantus prescribing
information but rather brushed off as with some wording about how one
tiny study found it and another didn't and it isn't clear what the
relationship is to the insulin.  Interestingly, worsening is NOT cited
as a side effect in the Levemir Prescribing Information that came with
my starter kit.

Interesting articles, though they seemed to show that Lispro didn't
increase the incidence of retinopathy in pregnant T1's.

BTW, there is even a name for what happened to me: normoglycaemic
re-entry phenomenon. Apparently, it's well known in ophthalmologic
circles.

I'd never heard of misc.sci.diabetes. Thanks! I'm thinking that I
might try both there and MHD as they might find it interesting. BTW, I

Frank,

I have been slogging through a couple of articles you posted, and thanks.  
From what I can gather (plese correct me if I am wrong)  Lispro seems to
be the particular insulin to avoid in order to prevent neovascularization.  
Is this just tht this iw what they happened to use in the test or could we
assume other insulins might be better on this score?

Wendy-just trying to make sense of it all.

Unfortunately, since this study takes place in the context of pregnancy,
the growth hormone environment is already altered, making the
application of results to non-pregnancy questionable.

Lantus is the insulin I have seen implicated in worsening, but the DCCT
retinopathy worsening results were gotten years ago in a population
using the older insulins.

The big unknown there is: how much of that was due to the big
infection? I've had differing opinion from Docs on that, but more than
one has told me that it would be impossible to get from there to
Euglycemic (normal) Bg's in 12 days, and remain there on just
metformin, if a big part of it wasn't the infection. Also, my A1C was
12.5, which is too low for 600+ fasting BG's. However, even that is in
doubt as I'd had the infection for weeks when Dx'd.

Oh, what I'd give for a few meter readings in the months before I had
the infection.

Let me clarify here: he is a retinal specialist who sub-specilazes in
diabetic retinopathy. And, after chatting with him on BG's A1c's, and
everything from incretin mimetics to peripheral neuropathy, I'm
convinced he knows a great deal about diabetes.

However, I'd certainly prefer to find a good study.

I am not referring to the studies, but do want to reiterater what my
macula specilaist, who deals with man diabetis as well as non0dibetics
with AMD(Adult Macula Degeneration{wet}).  Whe I describred Chris's
situaltion t him and asked, specifically, about what advice we should
think about giving on asd which he respects, (at lest a a concept) He sid
whe should not advise slower stivign for control, or slower lowering of
bgs,  dispite the rare problem  like Chris's of some retinopathy and
macular edema with fast reduction, as the long term benefits of rapidly
lowered bg's is so great.  

I do not know if he is speking form knowledge gained form research or from
a long expeience with diabetics as well resaerch.  

This doctor is delighted with my A1c's as well as my fsting glucose
readings and sees no canges in my slight background retinopathy which has
been stable for , at lest, the last 10 years.  He wishes all his diabetics
had similar readings.  (A1c-varyig between 5.2 and 5.9-fbgs between high
70's to low 90's)

The question I have with that is what, exactly, are the benefits of
RAPIDLY lowering BG's? And what would he define as rapid? Did you
mention that in my case I went from a fasting of 600+ to euglycemic
range in nine days? Would a month have been rapid enough? Or two?

But, I will say that it appears that Wendy's specialist contradicts
mine. I do know that Wendy's is very highly regarded in this field.

Mine said an A1c 6 or under is preferred as a goal. He also said "the
lower, the better". When he asked for my A1c, and I told him 5.4
3 months after Dx (he already knew my BG's at DX) he thought I was
mistaken and asked for my test sheet. Fortunately, I had it with me.
His comment was that in the long run, I'm much better off. My comment
was "not if this costs me my sight". He said he couldn't disagree
there. Shortly after this is when I asked for his recommendation for
newly Dx'd, and he came up with "slower would be better".

G'day G'day Wendy,

You're a gem.  You asked THE most important question needing to be
asked of someone qualified to answer it.  Special thanks for being up
front with what you wanted the answer for.  I'm sure it makes one heck
of a difference to a specialist to know how the answer they give will
be used.  For instance if they thought the patient wanted the
information for a court case their answers might be very different.

This explains my dilemma very well. At the moment there are too many
unknowns for me to know what the heck to say to a newbie about this.
I've decided to have a consultation conference with both the
specialist and ophthalmologist about this issue (what to say to
newbies). It's going to cost me, but it's sure worth it.

The biggest unknown: what rate of reduction is optimum? The big
problems here seem to be that the underlining mechanism for
normoglycemic re-entry retinopathy is not known. So, without knowing
the mechanism, it's hard to even theorize a good strategy.

My biggest fear at this point: that I'll end up with conflicting or
non-definitive answers, and then be faced with a newbie, and have no
clue as to what to say. And yes, that one *IS* keeping me up at night.

The problem is that there doesn't seem to be, so far, a definition of
what "too fast" is, or what the starting number danger zone is.  Then
there's the question of whether it's the method or the speed of lowering
that causes the problem?

Those are indeed parts of the problem. From what I've seen, even the
specialists (Mine, and Wendy's) disagree, so I'm wondering if I'll
ever be able to figure this out. I'm going to try, though.

I would wager, without actually knowing, that it's the growth factor
from the intensive use of insulin during rapid lowering that's
responsible.  If you'd been instructed on proper diet at the time, you
wouldn't have needed nearly as much insulin.

OTOH, we still don't know how much the threshold of "too much" would
have been.

Months of glucose toxicity wouldn't be any safer, necessarily.

IGF-1 seems to be triggered also by the change in BG's themselves.

That's not true in my case. If anything, I went too far the other way,
and thus needed very little insulin and for a very short time. My diet
was exceedingly low carb and low calorie in those early days.

My total insulin use, for the entire time I was on insulin, was under
100 units (not counting one day in hospital, and I don't know the
totals for that day).

My mistake; I know you ate way too little and extreme low carb at home,
but I thought you'd been in the hospital on an awful diet and insulin to
cover it for longer.

Even in the hospital, there was quite a difference between what they
tried to feed me, and what I actually ate. However, my eating in the
hospital was by no means healthy, just a lot healthier than what they
tried to feed me.

I was only in a day and a half, and only ate two meals there (one
Breakfast, and one dinner). So, I doubt it could have had much effect
no matter what I'd have eaten there.

G'day G'day Susan,

This is all too reminiscent of the issue of exercise with newly
diagnosed T2 diabetics.  We all know exercise is so important that it
comes first.

Here is a rough guide to dealing with T2 diabetics.

1.  Exercise.
2.  Exercise and diet.
3.  Exercise, diet and take oral medications.
4.  Exercise, diet, take insulin.

It is tempting to think everyone should exercise if they are T2
diabetics.  Forget for the moment those who are crippled and consider
just those who have high blood pressure.  Sometimes it is vital to get
the high blood pressure in check before engaging in vigorous exercise.
It can be fatal not to do so.  Other people write about these matters
of high blood pressure and exercise so much more elegantly than me,
I'd rather leave the details to them.

The point I'm driving at here is that for MOST people getting rapid
tight control is not problematic at all.  If they get cracking they'll
simply get healthier and reduce a multitude of risks.  Then there are
those who start out with enormously elevated blood glucose.  Let's say
for arguments sake that we probably recognise people likely to be that
group.  They are most likely a subgroup of those who need insulin
immediately to overcome glucose toxicity.  

At least we now have a name we can use for searching for information
on the issue.

Best wishes,

And it must not be forgotten that the problem is documented ONLY found
in people who lower glucose using insulin, almost all of them Type 1s.

Another point to remember: The danger of a blood sugar of 600 in a
person who still produces their own insulin is death from something
called hyperosmolar Coma. This condition occurs in people who do not
develop ketoacidosis because unlike type 1s, their bodies don't consume
their own tissue with extremely high blood sugars. But the dehydration
this condition causes can be fatal or can cause permanent brain damage.

That probably is why doctors would administer large doses of insulin
immediately to anyone with a fasting blood sugar of 600 mg/dl.

G'day G'day Chris,

WOW.  You are one impressive bloke.  It's a privilege to be able to
call you are friend even if we have never met.  In New Zealand much of
the specialist care come care of the state if recommended by doctors
and one doesn't mind waiting.  Not so in some places elsewhere.  I'm
deeply impressed that someone would dig deep into their pockets to
find out information which can't materially change their own situation
but could be a benefit to countless others.

Why do we care so much?  
It's not an easy question to find an answer to.

Thank you my friend. I can't take too much credit for this, though. I
have a pressing need for some good to come out of my experience. It
sure as heck beats stewing about it! :-)
I'm also holding out hope that, given my purpose, the two Docs might
go easy on the billing for this one (I won't be trying to get my
insurance to cover it). :-)  

There is indeed some waiting here, though it's on the order of days,
not weeks. I had to wait two weeks for my initial appointment, and I'm
still trying to set up the conference. However, part of the waiting in
this case was due to me not being near a city. Had I wished, I could
have probably found a good ophthalmologist in Phoenix who would see me
very soon. However, due to wanting to use the one who was familiar
with me, and one I knew my insurance would accept, I chose to wait two
weeks. I also didn't know there was anything amiss, so the waiting
seemed like no big deal.

Given who signed one of the emails and the content, the conclusion is
inescapable.

This isn't the first time if I've wondered whether bad temper and
paranoia might also be diabetic complications.

It does seem to go hand in hand with lousy diet and/or glycemic control.

so susan since you brag about having such a good diet then what do you
blame your paranoia and being an a-hole on? hmmm?

TO ALL NEWBIES: please keep in mind when reading advice from susan and
other shere that you should first find out what the state of their
health is, how much they exercise, what medical problems they have, and
what kind of medications they are taking. this has a direct impact on
what advice they are giving to others.  you'd be surprised to find out
the loudest voices in here are usally the ones with the most medical
problems.  don't be bullied into being like them!

The only thing I'm deeply sorry about is that you have to go through
this nightmare with your eyes!

The only reason I brought this distasteful issue up was to make sure you
 understood that not everyone reads critically and with the kind of
intelligence you bring to a topic.  And when a topic as emotional as
blindness comes up among people with diabetes, emotion really enters the
picture.  Stir in a pinch of the usual newsgroup conflicts, and the
result is pretty predictable, if sad.

Hopefully when you have dug around and asked your questions, we'll all
end up knowing a lot more about how to protect our eyes. Or if nothing
else, we'll know this is another area where there's a lot we need to
know that no one has gotten around to figuring out--which seems to be
where all too much related to diabetes sits right now.

Thanks, but I'm dealing with it OK. The waiting is the hard part, but
I'll know a lot more in about a week.

Weirdly, I don't tend to stress out over major stuff. I have for
example stressed out a lot more over a single blood sugar spike than I
did over an arguably more serious aviation emergency: On my long
cross-country solo as a student pilot, I had a massive fuel leak which
required me to shut down both the engine and electrical system. It was
a low wing single engine (Piper Cherokee) that had very poor glide
characteristics, and also electric flaps (which I couldn't use). I had
to dead-stick that flying bomb into an emergency landing, no flaps (so
a much higher than normal touchdown speed, something I'd never done
before.) and make darn sure there were no sparks. Couldn't use the
brakes as I suspected fuel in them, too. I ended the rollout at an
airport restaurant, with several feet to spare. I had only one injury
from that: while walking away from the plane after the landing, my
knees went weak and I fell down and skinned my elbow. (go ahead and
laugh, I sure did!) But, I wasn't nervous or stressed until I was
safe.

Thanks... I've been expecting trouble over this, and that doesn't
bother me (I have a very thick skin when needed). What does bother me
is anyone else (you in this case) being caught in the crossfire.

That's my sole interest in keeping this topic going so long.

Not that anything on your site is capable of leading to blindness, but
I feel it would be a good idea to mention that I was already off of
insulin (and thus the damage probably done) *BEFORE* I read Jenny's
site.

This is how the human mind works, When my Sweetie was taken to the
hospital in a state of near-shock, bleeding out, and went into
convulsions in the ER, I remember how strangely calm I felt. In the back
of my mind was the thought, "How odd. He might die, and I don't feel
anything." Same when my 11 year old daughter underwent two dreadful
surgeries on her jaw. Only when they were both clearly out of danger did
the emotions kick in. When my daughter was finally safe I ended up
getting extremely sick, probably from the stored up terror.

OTOH, maybe your story is also a pilot thing. My brother is a small
plane pilot and on his last trip across the country in a plane built in
1966 he'd call me every night with cheery reports on how his radio had
broken or how some piece had fallen off the plane requiring the
emergency landing in Nebraska where a guy at a gas station had tied
something together till he could get to an airport, etc. etc. I'd stay
up all night worrying, but he was having the time of his life. He did
end up losing his plane, eventually--it was turned over and smashed by a
downdraft when it was tethered at its home airport.

Those kind of stresses are about the worst imaginable IMHO. I'm glad
you all made it ok.

ROFL!!!!!!!! Yep, he's a pilot. I never did understand the look of
horror on a friend's face when I mentioned that I needed to borrow a
pencil for my flight, so I could plug up a broken vacuum line so the
vacuum driven instruments would work.

I've been in a few anxious moments on commercial airliners, including
severe turbulence (enough to cause a loss of several thousand feet of
altitude), a near mid-air collision over Dallas, and a partial stall
due to avoiding a mid-air near NY. I've had a few minor airline scares
such as a blown tire on landing, and an engine failure on takeoff,
too. Actually, all those bothered me more that my emergency as a
pilot, because as a passenger I was helpless. I've heard quite a few
people comment on logan approaches. I've never been there, so I can't
say. I do remember flying into Hong Kong (the old airport in Kowloon,
not the new one on the island) and you literally thread the tall
buildings on final.    

The approach to the airport (when i had my fuel leak) was fun. I had
shut off the master electrical switch, so had no radio (or anything
else electrical, including transponder). I also didn't know if I had
enough altitude to make it to the airport. For a while, I thought I'd
have to set it down on a dirt road (which would have been fun with a
landing speed of over 100mph). Fortunately for me, I picked up a bit
of a tailwind, and stretched it out enough. But, I was a new pilot,
and had never done a dead-stick before in the type of aircraft, so I
darn near blew the landing. I had also never flown a straight in
approach before, nor landed without flaps, and I found I was coming in
hot on final (would have touched down too far down the runway). Being
dead stick, I couldn't go around, and I had to crab the thing at full
rudder, then keep reversing it, to increase my rate of decent. I
overdid it and barely cleared the airport fence. I held it off the
ground as long as I could, and set the wheels down on the threshold.
weirdly, it was probably the smoothest landing I ever made, didn't
even feel a bump.

I probably wasn't in too much danger at that point, as I'd have used
the breaks if I absolutely had to. I later learned that I'd have been
unlikely to set myself on fire by doing so, but I didn't know that
then.

Half an hour later, I'd fixed the leak and was in the air again, no
worse for wear (except for my skinned elbow).

That's disgusting. Apart from being an outright lie! Your research is like a
wake-up call - "Hey! You need to know this, and the starting point is right
here - in English, not medicalese!" That's how I felt/feel, anyway! Please
don't let the nutters make you feel bad!

Thanks, interesting!
However, I do wish someone would do a study to examine the increased
incidence and severity of normoglycemic re-entry retinopathy (the name
for what happened to me) when temporary insulin intervention is used.

But, that 6 month figure is very interesting!!! I'll bounce it off my
retinal specialist next week.

Chris,

The ONLY increases in retinopathy reported in the literature are found
in a small percentage of people (almost all type 1s) using insulin.

It is not an issue in people NOT using insulin, which is very important
to keep in mind before telling newbies with type 2 that they will go
blind if they bring down their blood sugar with dietary control.
