How Does Diabetes Affect the Eyes?

People with diabetes often have problems with the blood vessels in the eyes. If you look at the inside of a human eye, you will find the retina lining the back. This area detects light and shadows, sending visual information through the optical nerve to the brain. A healthy retina needs a steady supply of blood, rich in vital nutrients. Diabetes can cause blood vessel damage in the retina, which causes vision problems.

Diabetes can impair the ability of blood vessels to supply nutrients and oxygen to the retina. If any part of the retina becomes deprived of oxygen, it will send out a signal to get more blood supply. The body will start growing additional blood vessels to supply this much-needed oxygen. However, these new vessels, called neovascularization, do not grow normally. Instead of growing within the tissue of the eye, these blood vessels grow within a membrane along the retina’s surface. Due to changes in eye fluid or blood pressure, the membrane will contract. Squeezing this membrane can cause the new blood vessels to tear. The person will have an area of their vision darken as the blood gathers.

The blood may dissipate on its own. However, if it does not, it can trigger the formation of additional membranes which may cause the retina to detach from the inside of the eye. A detached retina can also cause dark spots in vision. This kind of eye injury requires the immediate attention of an ophthalmologist to prevent permanent damage.

Neovascularization can occur with no noticeable changes to your vision. Diabetics need to have regular eye exams to ensure that this silent condition does not cause permanent eye damage.

Diabetes can also weaken the walls of the vessels, causing them to leak. The leaking fluid can accumulate within the macula, which is the central vision spot on the retina. The accumulated fluid can cause vision to become blurry, a condition known as diabetic macular edema. It is the major cause of vision problems in people with diabetes.

Patients who have diabetes have a higher chance of developing cataracts at a younger age than most people. When a cataract forms, the person experiences clouding of the lens, which affects the light focused on the retinal surface. Diabetics may form cataracts due to ups and downs in glucose levels. This can pull water into the tissues of the lens, which makes vision cloudy.

Facts About Diabetes

  • There is no known cure.
  • Over 29 million Americans have diabetes. That is over eight percent of the population.
  • When a person has diabetes, the body does not produce enough insulin or the body is not properly responding to insulin. Insulin is essential for converting sugar, starches, and other carbohydrates into energy.
  • Those with diabetes can experience severe complications, such as high blood pressure, heart disease, high LDL cholesterol, kidney disease, blindness, nerve damage, gum disease and significant infections. It is not uncommon for diabetics to need amputations.
  • Diabetes is silent and deadly. In 2010, over 230,000 deaths in the U.S. had diabetes mentioned as a cause of death.

Fortunately, there is a lot you can do to manage diabetes. The most important thing to do is get the disease under control. Changes in diet and exercise can help you keep blood sugar levels close to normal. This will help you avoid or delay complications.

Are You or Someone You Know at Risk for Diabetes?

You may be at risk for developing diabetes if you have the following characteristics:

  • Are 45 or older.
  • Are overweight or obese.
  • Live a sedentary lifestyle.
  • Have family members who are diabetics.
  • Had a baby who weighed nine pounds or more at birth.
  • Are of African-American, Hispanic or Native American descent.

What Will Happen During a Diabetic Eye Exam?

The doctor needs to examine the retina. To do this, your eye will be dilated.

The doctor will be looking for changes within the retina, such as blood spots, leaking blood vessels or white areas indicating damage to the nerves. All of these changes are related to the blood vessel damage caused by diabetes. The doctor will also note if there are any abnormal blood vessels growing on the retina’s surface. With this condition, there is a significant chance that bleeding will occur. The doctor will also examine the macula for diabetic macular edema.

Can Diabetic Eye Disease Be Treated?

The good news is that many of the conditions that diabetes can cause within the eye are treatable, as long as they are caught early enough.

The current recommended treatment for the abnormal blood vessels forming on the retina is pan retinal photocoagulation, a type of laser treatment. The doctor will use the laser to destroy the places where blood vessels have closed and new blood vessels are forming. After treatment, the retina will stop signaling for new blood vessel formation. The new ones already present will start to go away. This treatment can cause complications, such as bleeding in the eye or retinal detachment. However, the Diabetic Retinopathy Study (DRS) verified that the risk of significant visual loss due to the growth of abnormal blood vessels on the retina can go down by more than 50 percent with the use of this treatment.

The same laser treatment works to treat the leaks in blood vessels that cause diabetic macular edema. The doctor may order a special angiogram to detect exactly where the leaks are occurring. This makes treatment more precise.

Can Complications from Diabetic Eye Disease Be Prevented?

Visit your eye doctor every year. That is the most important thing you can do to prevent eye problems caused by diabetes. If you were diagnosed with diabetes, your primary care physician should have sent you to see the eye doctor right after you were diagnosed. You need an annual exam every year after that. For diabetic women who become pregnant, exams need to happen during every three months of pregnancy and then three months after the baby arrives, since the abnormal growth of blood vessels within the eyes can become worse during pregnancy.

If your primary care physician or eye doctor finds changes in the retina, you may have to go in for eye exams more than once a year. This allows the doctor to monitor the changes.

People with diabetes need to visit their physicians regularly, to keep control of the disease. Controlling blood sugar levels can decrease the risk of abnormal blood vessels growing within the eye.

How Much Does Diabetic Eye Care Treatment Cost in Houston?

  • Even if your insurance plan doesn’t cover vision correction, you can use cash, a credit card, or approved financing for payment.
  • Choose from no-interest plans, extended payment options up to 48 months and no down payment.
