___Even tho your sugar is not high at the time, it does not mean that diabetes is not damaging your eyes. Diabetic retinopathy is common after an extended period of having the disease. The best way to find out is to see a good optometrist or other eye doctor or surgeon.
___I give my wife aminoguanidine hcl, 300mg/daily in order to prevent this and kidney problems. My source is no longer in business and I am desperately seeking another source. It is a common medicine prescribed in Europe, but not in the U.S. due to our FDA. It has not been submitted to them for approval, but if you want to donate about 50 million for lab tests and possible bribery, you could likely get it approved. However, it's an old drug that cannot be patented, so you won't get any return on investment.
My wife was warned about her having a touch of it apparent in her retinas, so I scoured the internet and found a source. I also researched clinical trials and found that it is highly effective in delaying both of these events. I bought enough for about 6 months, but am now getting low. On her last trip to the optometrist, he found there was some reversal. I found one source, but my minimum order is 10 kilo's at $200/K...something I can't afford as yet.
___There is a substitute for this to some extent. L-arginine and vitamin B6 in combination. I will be researchin the dosage pretty soon if I can't find the AG. In fact, I may do this anyway...stay tuned to the boards....God bless,,,,Oldguy
Hello again Barb,
I noticed you're a nurse anesthetist; if you know what an iNos (induceable Nitric Oxide Synthase) inhibitor is then you'll know the function of aminoguanidine. Its the endogenously produced excess of NO (actually nitrogen monoxide incorrectly called nitric oxide, nitrous oxide, etc. in clinical papers), that destroys: retinal arteries, Islet cells in the pancreas, and the kidneys. Ask one of your doctor endocrinologists.
Hurry and have your eyes checked for retinal damage....Pray that you don't have it and I'll join you....Oldguy
spellin errors..tsk, tsk

Thanks for the info. I am not familure with this and will do some research and reading. I do have a scheduled eye appt. in the beginning of April. For as much as I know ,I am constantly learning how much I do not know. I know a lot about anesthesia and diabetes but that is limited as to the body of knowledge in treating this disease. Are you a doctor? I can't figure out how to check profiles. You seem so informed with indepth info. Thanks again, Barb
___No I'm not a doctor, but just a wannabe. Actually, I started in premed for 2 years and some credit hours, but changed to engineering, both mechanical, and electrical. But my love has always been medicine, physiology, and cellular biology. I do an awful lot of research. My wife gave me a lot of flack about my book investment, and time invested on the computer reading anything and everything in medical science. I generally don't get along with doctors right away because they take me as a threat, but after a while, we start to talk on the same wavelength. I have a PCP named Dr. Garcia who is so open minded that we discuss everything just like med students. He doesn't treat me as a Cro-Magnon.

___PS: I know very little about anesthesiology. Remember, a general practitioner is a doctor that know less and less about more and more, until he knows nothing about everything. Aspecialist is a doctor who knows more and more about less and less until he knows everything about nothing....WOW (words of wisdom).

BJ- Have you checked your blood pressure? You could be having tia's, you could have an occluded blood vessel, a pinched optic nerve, occular migranes (that's what I have), even early cataracts. I had very cloudy vision, off and on, but peripherially. I was diagnosed with early cataracts, periphially, as well as ocular migranes. Please check your blood pressure and take note of any other symptoms you may have. If they continue or get worse, get thee to a doctor or emergency room. Don't wait for the appointment if you have a problem now. Best of luck to you...
I have been checking my blood sugars and the times my vision is blurred does NOT corrolate to high sugars.
Hi fellow sufferer,
I hope to have good news for you.I am about 90% sure that you do not have retinal damage. I had the same kind of scare on an unbelievable level. After being involved in an accident I suffered trauma induced high blood sugar. My eyes became so clear that I no longer needed my glasses. I also developed a nasty taste in my mouth.
When my blood sugar was checked it was off the scale of the meter ( more than 450mg)
As my blood sugar level came down my vision became extremely blurred and I was very scared. For a while I had to wear some strong reading glasses over my ordinary specs. But it came right back to normal.
I have every respect for all the people warning you about about retinal damage, but the clue that assures me that you have a different (less traumatic) problem is when you say that it does not appear to correspond with blood sugar levels...it Does but in the opposite way to what you would expect.As your sugar level goes down your vision becomes blurred....but the good news is no permanent damage to your eyes.
I hope this gives you the tremendous relief that it gave me.
I am hoping to include in this post(I am not a computer buff!) a copy of some text from a web site that will hopefully put your mind at rest. The site is called: [url="http://www.diabetesnet.com/eyes.html"]www.diabetesnet.com/eyes.html[/url]
This is what they say:
Changes in vision may happen at the time that diabetes is first diagnosed or at any time that blood sugar control is poor. Fluctuating blood sugars cause the lens to swell and shrink, and result in fluctuating vision. Many times, people who have "borderline" diabetes finally decide to take their diabetes seriously when their vision becomes blurred.
Sometimes, people coming down with diabetes marvel that they no longer need their glasses to see in the distance. But as insulin or other therapy is begun and the blood sugar drops, the abnormal swelling diminishes. In the short-term vision becomes blurred and is not corrected by their prescription lenses. Either of these scenarios can be frightening to people who have heard of the severe eye damage that goes along with diabetes.
Blurred vision in both eyes when insulin or other treatment begins is almost never caused by damage to the eye. Rather, it results from the speed at which the swelling, due to high blood sugars in the previous weeks and months, dissipates from the lens. Vision is usually out of sync for 3 to 4 weeks, sometimes with an accompanying headache.
After a visit to the physician to confirm that the abnormal vision is actually a temporary problem caused by lowering the blood sugars, a common treatment is to visit the reading glasses section in a large pharmacy. There, the person tries on different strengths of "reading glasses" until he finds one that allows him to see clearly at distances. As the days pass, a weaker version may be needed until eventually his own prescription lenses again work. Never buy prescription lenses during any period of uncontrolled blood sugars. These lenses are unlikely to work once the blood sugar is normalized.
These vision changes at the time diabetes is diagnosed rarely indicate real damage unless uncontrolled high blood sugars have been present for 5 years or more. It takes about 5 years of elevated blood sugars before damage to the eyes can be seen with an ophthalmoscope. However, the "It ain't gonna happen to me crowd" should remember that whenever blood sugars are high, damage may be underway and once it starts, it becomes much harder to stop!
I shall be so happy if this helps!

___What you said is really interesting..first time I ever heard of it. I take it this doesn't happen too often..My wife is brittle and hits 500 fairly often only to drop to 180 in short order after a quick shot. Is this swelling due to inflammation or some form of osmotic pressure? I'm going to have to lookinto this..thanks again and God bless,,
You will probably have read the web site by now so just one more thing to add from my experience that may apply to your wife too:
The article gives the impression that this swelling and shrinking of the eyeball takes a bit of time to process. In my experience it can happen quite quickly.
I am type 2 diabetic (so not insulin dependant) and in general my sugar level is fairly well under control. However , a couple of times I have been just too busy to eat lunch, because of attending meetings etc, and then I have found this blurred vision coming on quite quickly. It acts like a barometer of blood sugar.
Each time this has happened (about 3 times in 6 months) rightly or wrongly, I have eaten a Snickers bar or similar choc goodie and after about 30 mins my vision is clear again.
I am so pleased to hear from you and ask you if you could please share any thing you can learn with me.
You will have a far more experienced idea about how to investigate this.
I hope that bjk47, who started all this, gets to see our discussion and that it helps him, or her? too.
And God bless you and your wife TOO

You're right, I have read the websight, plus all of its links. It's a good one alright, and very informative and straightforward for the layman. As for prevention of eye damage, trials of vitamin A have not shown too mch gain, but high dosages of B6 and aspirin therapy show some pretty good results. As for my wife, I give her aminoguanidin hcl. that I got from a website that is now out of business. I'm beating the bushes for another source. I got a reply from one, but the minimum I can order is 10 kilo's at 200 dollars a kilo. That's a bit high for me, but if I can't get another source, I'll have to sell my three dogs, and son-in-law to get it. It is 87% effective in preventing retinopathy, retinal neovascularization (as they call it),and damage to the kidneys by advanced glycation end products (sugar damaged aberrant proteins). If I find a source, I'll post it. It's not supposed to regenerate the eye, but my wife's eye doctor thinks there has been some reversal. Tomorrow my wife and I have our fasting blood tests and will get our results a couple of days after. I'm interested to see if the aminoguanidine has lowered her Hba1c.. If it did, it isn't because of her blood glucose coming under control. I'll post her numbers after I get them...Thanks again for the tip.. and God bless you and yours, Oldguy
Hi, haven't had time to check the boards recently. My blood pressure is fine so I'm not worried there. Fullscale, thanks, that makes so much sense. My sugars had been elevated and I have been getting them under better control over the last month. My vision has cleared over the last week. I started taking a supplement several weeks ago from my kinesiologist called ocu-clear, among other vitamens it has taurine bilberry extract, ginkgo quercetin chalcone, alph lipoic acid and lutein. So don't know if that has really helped or if normalizing sugars helped too.
This happened once before to me when my sugars were elevated, not coming down. And the opthmologist at the time explained the osmotic pressure changed the lens and caused the blurred vision. But I was concerned because this was different and as you described, lowering blood sugars. So you get blurred vision always when you get low blood sugar?? or just sometimes?
Thanks so much for the information and the web site, I will check it out. Barb
Hi Barb...glad you found the info usefull.
In answer to your question ....I only get blurred vision if I don't eat for many hours and my sugar level goes way down.
I can't tell you how much it helps to contact others with the same problems. When I had to go around wearing 2 pairs of glasses everyone thought I had flipped!
God bless and keep well.
I am going to a new eye doctor in a short while and I will ask him if he has heard of this. I will have to pay more attention to the blurred vision, sometimes it is not as bad as others and it does not seem to be acuteutely situational, ie 1 isolated low sugar, at least for me. I keep meaning to keep a journal for things like this and get started then slip up. Thanks again
