Does diabetes worsen vision?

Question

I have been diabetic for 19 years, and am in my 20's. I recently gotten my levels under very good control, but my vision seems to be worse when my levels are normal than when they're up where they used to be... Is this due to diabetes or is my vision just changing? I do have astigmatism in my left eye and nearsighted in my right...

Answer 1

Check with your opthalmologist and make sure he is aware of your medical condition. Diabetes CAN affect your vision, but so can many other things, including your age. I recommend an opthalmologist rather than just an optometrist because of your medical condition and possible problems in the future. It is best to start young with someone with experience so they have a baseline to judge from as you grow older or your condition worsens.

Diabetes is the number one cause of blindness in the United States. Although diabetics have a high sugar count in the blood along with insufficient insulin production, the real damage is done by lack of oxygen. Because the eyes have such tiny blood vessels and yet need a lot of blood (and therefore oxygen), diabetes can cause a great deal of damage. The veins in the eyes can leak, which can cause scarring and loss of vision.

People with diabetes should never neglect visual symptoms because they might be due to complications of the disease. Early diagnosis and treatment can reduce vision loss. Some symptoms may be corrected with standard prescription lenses, while others may need medication or surgery. However, if the damage to the eye has progressed to hemorrhaging and scarring, remaining vision cannot be restored to normal levels.

The most common diabetes-related eye symptoms are:

changes in refraction, variable vision or focus;
blurred or hazy vision;
sensitivity to glare;
faulty color vision;
blindness.

About 40 percent of people with diabetes will have at least mild retinopathy.
Retinopathy causes blurred or hazy vision, particularly if there are retinal hemorrhages or edema (swelling) of the macula.
Early treatment may restore vision, stabilize it or, at least, delay severe loss of sight.

More than one-third of those diagnosed with diabetes do not adhere to vision care guidelines by obtaining a dilated eye exam every year. As part of November's Diabetic Eye Disease Awareness Month, ophthalmologists across the country are urging Americans diagnosed with diabetes to have a dilated eye exam every year.

What are the signs to look for?

Because fluctuations in blood sugar levels can temporarily affect vision, it's sometimes hard to know if a serious eye problem is developing. That's one of the reasons good control of your blood sugar is so important. If you notice a vision change in one eye--a change that lasts more than a day or two or a change not associated with fluctuations in blood sugar--call your eye specialist promptly.

Patients with controlled diabetes do better than those with uncontrolled diabetes. However, even the diabetic who is under perfect control can still develop diabetic retinopathy — hence, the need for yearly retinal exams.

Chances are that your medical doctor will eventually send you to the eye doctor. I would go there first, since it sounds like your only symptom right now is vision related.

I'm a 45 year old woman and was recently diagnosed as being a borderline diabetic. My doctor prescribed some medication, but before filling it I decided to do some research on the internet which led me to the methods. After reading this ebook and applying the methods, my scepticism turned to 100% belief. I noticed that my energy levels increased significantly and I felt more rested in the morning, my symptoms started going away.

I am very happy to tell you that I have been feeling better than I have felt in years and my doctor informed me that he will be taking me off my prescriptions if I keep this up.

Diabetes very much affects the eyes. You are lucky that you have had the disease as long as you have and are just noticing it. The older you get they will get worse. One of the signs for people to look for if they think they may be diabetic is worsening of the vision.

Answer 7

You need to have a yearly eye examination. high blood sugars cause swelling in the lens of the eye that returns to normal when the blood sugars normalize. On the other hand, rarely if your blood glucose has been controlled over a very short period of time (for example they were very high 2 weeks ago and now they are normal), this can cause worsening diabetic retinopathy. I guess the bottom line is that you need an eye doctor examination.

Answer 8

Diabetes does affect vision. Most eye doctors will suggest that you not get glasses until you have your blood glucose levels under control.

In my case, when my levels are under control, my eyes seem to be a bit better than when my levels are higher. My wife is also a diabetic, and it is just the opposite with her.
