Blood sugar control and eye health -
Damaged blood vessels may leak fluid and cause swelling. New, weak blood vessels may also begin to grow. These blood vessels can bleed into the middle part of the eye, lead to scarring, or cause dangerously high pressure inside your eye.
Most serious diabetic eye diseases begin with blood vessel problems. The four eye diseases that can threaten your sight are. The retina is the inner lining at the back of each eye. The retina senses light and turns it into signals that your brain decodes, so you can see the world around you.
Damaged blood vessels can harm the retina, causing a disease called diabetic retinopathy. In early diabetic retinopathy, blood vessels can weaken, bulge, or leak into the retina. This stage is called nonproliferative diabetic retinopathy. If the disease gets worse, some blood vessels close off, which causes new blood vessels to grow, or proliferate, on the surface of the retina.
This stage is called proliferative diabetic retinopathy. These abnormal new blood vessels can lead to serious vision problems. The part of your retina that you need for reading, driving, and seeing faces is called the macula. Diabetes can lead to swelling in the macula, which is called diabetic macular edema.
Over time, this disease can destroy the sharp vision in this part of the eye, leading to partial vision loss or blindness. Macular edema usually develops in people who already have other signs of diabetic retinopathy. Glaucoma is a group of eye diseases that can damage the optic nerve—the bundle of nerves that connects the eye to the brain.
Diabetes doubles the chances of having glaucoma, which can lead to vision loss and blindness if not treated early. Symptoms depend on which type of glaucoma you have. Learn more about glaucoma. The lenses within our eyes are clear structures that help provide sharp vision—but they tend to become cloudy as we age.
People with diabetes are more likely to develop cloudy lenses, called cataracts. People with diabetes can develop cataracts at an earlier age than people without diabetes. Researchers think that high glucose levels cause deposits to build up in the lenses of your eyes. About one in three people with diabetes who are older than age 40 already have some signs of diabetic retinopathy.
Finding and treating diabetic retinopathy early can reduce the risk of blindness by 95 percent. Your chances of developing glaucoma or cataracts are about twice that of someone without diabetes.
Some groups are affected more than others. If you have diabetes and become pregnant, you can develop eye problems very quickly during your pregnancy. If you already have some diabetic retinopathy, it can get worse during pregnancy.
Changes that help your body support a growing baby may put stress on the blood vessels in your eyes. Your health care team will suggest regular eye exams during pregnancy to catch and treat problems early and protect your vision.
Diabetes that occurs only during pregnancy, called gestational diabetes , does not usually cause eye problems. Researchers aren't sure why this is the case. Often there are no early symptoms of diabetic eye disease.
You may have no pain and no change in your vision as damage begins to grow inside your eyes, particularly with diabetic retinopathy. Call a doctor right away if you notice sudden changes to your vision, including flashes of light or many more spots floaters than usual. You also should see a doctor right away if it looks like a curtain is pulled over your eyes.
These changes in your sight can be symptoms of a detached retina , which is a medical emergency. Having a full, dilated eye exam is the best way to check for eye problems from diabetes.
Your doctor will place drops in your eyes to widen your pupils. This allows the doctor to examine a larger area at the back of each eye, using a special magnifying lens.
Your vision will be blurry for a few hours after a dilated exam. Most people with diabetes should see an eye care professional once a year for a complete eye exam. Your own health care team may suggest a different plan, based on your type of diabetes and the time since you were first diagnosed.
Your doctor may recommend having eye exams more often than once a year, along with management of your diabetes. This means managing your diabetes ABCs, which include your A1c, blood pressure, and cholesterol; and quitting smoking.
Ask your health care team what you can do to reach your goals. Doctors may treat advanced eye problems with medicine, laser treatments, surgery, or a combination of these options. Your doctor may treat your eyes with anti-VEGF medicine, such as aflibercept, bevacizumab, or ranibizumab.
These medicines block the growth of abnormal blood vessels in the eye. Anti-VEGF medicines can also stop fluid leaks, which can help treat diabetic macular edema. The doctor will inject an anti-VEGF medicine into your eyes during office visits.
You'll have several treatments during the first few months, then fewer treatments after you finish the first round of therapy. If this happens, you may see dark, floating spots or streaks that look like cobwebs. Without treatment, scars can form in the back of the eye.
Blood vessels may also start to bleed again, or the bleeding may get worse. Diabetic retinopathy can lead to other serious eye conditions:.

Diabetes damages blood vessels all over the body. The damage to your eyes starts when sugar blocks the tiny blood vessels that go to your retina, causing them to leak fluid or bleed. These new blood vessels can leak or bleed easily.

If you do develop diabetic retinopathy, early treatment can stop the damage and prevent blindness. If your eye doctor thinks you may have severe diabetic retinopathy or DME, they may do a test called a fluorescein angiogram.
This test lets the doctor see pictures of the blood vessels in your retina. Managing your diabetes is the best way to lower your risk of diabetic retinopathy. That means keeping your blood sugar levels in a healthy range. This test shows your average blood sugar level over the past 3 months.

So controlling your blood pressure and cholesterol can also help lower your risk for vision loss. In the early stages of diabetic retinopathy, your eye doctor will probably just keep track of how your eyes are doing.
Some people with diabetic retinopathy may need a comprehensive dilated eye exam as often as every 2 to 4 months. Medicines called anti-VEGF drugs can slow down or reverse diabetic retinopathy.
Other medicines, called corticosteroids, can also help. Learn more about injections. Laser treatment. To reduce swelling in your retina, eye doctors can use lasers to make the blood vessels shrink and stop leaking. Learn more about laser treatment for diabetic retinopathy.
