What to know about diabetic retinopathy

Knobbe, MD. Diabetic retinopathy — vision-threatening damage to the retina of the eye caused by diabetes — is the leading cause of blindness among working-age Americans. The good news: Diabetic retinopathy can often be prevented with early detection, proper management of your diabetes and routine eye exams performed by your optometrist or ophthalmologist.

This causes glucose sugar levels in the bloodstream to rise and can eventually damage the eyes, kidneys, nerves or heart, according to the American Diabetes Association ADA.

Between 12, and 24, new cases of blindness from diabetic retinopathy occur in the U. But a significant percentage of Americans with diabetes are not aware of their risk of vision impairment from the disease. In fact, according to a survey conducted by Everyday Health, less than half of adults with diabetes in the U.

People who are most vulnerable to diabetic retinopathy, including the elderly and certain minorities, may not receive appropriate eye care because of lack of health insurance or access even to primary care physicians. For these reasons, make sure you promptly advocate for your own eye health and that of affected family members or friends when any kind of diabetes is present. Generally, diabetics don't develop diabetic retinopathy until they have had diabetes for at least 10 years.

But it is unwise to wait that long for an eye exam. With any diagnosis of diabetes, your primary care physician should refer you to an eye doctor optometrist or ophthalmologist for a dilated eye exam at least once a year.

Diabetes mellitus DM causes abnormal changes in the blood sugar glucose that your body ordinarily converts into energy to fuel different bodily functions. When you are diagnosed with Type 1 diabetes, you are considered insulin-dependent because you will need injections or other medications to supply the insulin your body is unable to produce on its own. Type 2 diabetes: When you are diagnosed with Type 2 diabetes, you are generally considered non-insulin-dependent or insulin-resistant.

With this type of diabetes, you produce enough insulin but your body is unable to make proper use of it. Your body then compensates by producing even more insulin, which can cause an accompanying abnormal increase in blood sugar levels. With both types of diabetes, abnormal spikes in blood sugar increase your risk of diabetic retinopathy.

Among other problems, diabetes can damage blood vessels in the retina, causing them to leak blood into the posterior of the eye. You may first notice diabetic retinopathy DR or other eye problems, including macular edema, related to diabetes if you experience symptoms such as:. During an eye examination, your eye doctor will look for other signs of diabetic retinopathy and diabetic eye disease. Signs of eye damage found in the retina can include swelling, deposits and evidence of bleeding or leakage of fluids from blood vessels.

Your eye doctor will use a special camera or other imaging device to photograph the retina and look for telltale signs of diabetes-related damage. In some cases, they may refer you to a retinal specialist for additional testing and possible treatment. For a definitive diagnosis, you may need to undergo a test called a fluorescein angiography. In this test, a dye is injected into your arm intravenously and gradually appears in the blood vessels of the retina, where it is illuminated to detect diabetes-related blood vessel changes and blood leakage in the retina.

One sometimes-overlooked symptom of diabetic eye disease is nerve damage neuropathy affecting ocular muscles that control eye movements. Symptoms can include involuntary eye movement nystagmus and double vision.

Once high blood sugar damages blood vessels in the retina, they can leak fluid or bleed. This causes the retina to swell and form deposits in early stages of diabetic retinopathy. Clinically significant macular edema CSME : This swelling of the macula is more commonly associated with Type 2 diabetes. Macular edema may cause reduced or distorted vision. Diabetic macular edema DME typically is classified in two ways:. If you have CSME, you typically are advised to undergo laser photocoagulation treatment.

Non-proliferative diabetic retinopathy NPDR : This early stage of DR — identified by deposits forming in the retina — can occur at any time after the onset of diabetes. Often no visual symptoms are present, but examination of the retina can reveal tiny dot and blot hemorrhages known as microaneurysms, which are a type of out-pouching of tiny blood vessels. In Type 1 diabetes, these early symptoms are rarely present earlier than three to four years after diagnosis.

Proliferative diabetic retinopathy PDR : Of the diabetic eye diseases, proliferative diabetic retinopathy has the greatest risk of visual loss. Development of abnormal blood vessels neovascularization on or adjacent to the optic nerve and vitreous. These abnormal blood vessels formed from neovascularization tend to break and bleed into the vitreous humor of the eye. Besides sudden vision loss, more permanent complications can include tractional retinal detachment and neovascular glaucoma.

Beyond the presence of diabetes, how well your blood sugar is controlled is a major factor determining how likely you are to develop diabetic retinopathy with accompanying vision loss. Uncontrolled high blood pressure hypertension has been associated with eye damage related to diabetes.

Also, studies have shown a greater rate of progression of diabetic retinopathy in diabetic women when they become pregnant. The American Academy of Ophthalmology AAO notes that all diabetics who have the disease long enough eventually will develop at least some degree of diabetic retinopathy, though less advanced forms of the eye disease may not lead to vision loss.

In the United States, minorities appear particularly vulnerable to vision loss caused by diabetic eye disease. NEI expects the number of black Americans with diabetic retinopathy will increase to more than one million by and to nearly two million by Also, a study conducted at the University of Alabama at Birmingham and Wills Eye Hospital in Philadelphia found that African-Americans with diabetes are among those at highest risk for diabetic retinopathy and have one of the lowest rates of eye care access.

Hispanics with diabetes are also at higher-than-average risk of developing diabetic retinopathy and vision loss. Native Americans are also at high risk of developing diabetes and related diabetic eye disease. You must make every effort through medical intervention and other remedies to address diabetes and diabetic retinopathy before you qualify for special considerations under the Americans with Disabilities Act ADA.

A disability basically means that you are substantially limited in the way you function in daily activity. When you are disabled, you are entitled to certain reasonable accommodations at the workplace and at public places such as schools.

The ADA also requires that diabetics in particular have certain protections under the law, such as needed breaks at the workplace for insulin injections or lunches at set times to maintain blood sugar levels.

You cannot be fired from your job or denied employment strictly because you are diabetic, as long as you are able to handle the basics of your work tasks. As an example, the American Diabetes Association says that a person with mild diabetic retinopathy might easily perform daytime tasks but could have difficulty with night vision.

In this case, special accommodation such as appropriate lighting might be needed at the workplace. If questions arise, you may need a letter from your physician that advises an employer regarding how well you will be able to perform certain work tasks. Any special accommodations you might need, such as extra lighting, could also be explained by your doctor s. State regulations governing disability differ, so you should also check guidelines established by the state in which you reside.

If you are visually impaired enough that you cannot work and expect the condition to last at least a year, you may be qualified for Social Security disability benefits. To qualify, you must have been in the workforce previously for a length of time that depends on your age. You can contact your local Social Security representative for details or go online to view specific U.

Social Security Administration guidelines at www. If you have diabetes or are at risk for diabetes and cannot afford an eye exam, there are programs available to help you obtain the eye care you need. Examples include:. Administered by the Optometry Cares — The AOA Foundation, this program provides free eye exams to uninsured, low-income workers and their families. EyeCare America. This public service program of the Foundation of the American Academy of Ophthalmology provides free eye exams for qualifying seniors.

Eligible individuals receive a comprehensive medical eye exam and up to one year of care for any disease diagnosed during the initial exam at no out-of-pocket cost. To determine if you or a senior family member or friend qualify for this program, visit the EyeCare America website.

Diabetic retinopathy

Diabetic retinopathy is the leading cause of blindness in the United States. At least 50 percent of all diabetics will develop diabetic retinopathy. In diabetic retinopathy, high blood sugar levels cause damage to blood vessels in the retina. These blood vessels can swell or leak, or they can close, preventing blood from circulating through them. In some cases, abnormal blood vessels grow on the retina. All of these changes can cause loss of vision.


Diabetic retinopathy is the most common cause of irreversible blindness in working-age Americans. If the physician detects signs of diabetic retinopathy, she/.

If you have diabetes, it is vital that you have your eyes checked regularly. Damage to the retina at the back of the eye retinopathy is a common complication of diabetes. If left untreated, it can become worse and cause some loss of vision, or total loss of vision severe sight impairment in severe cases. Good control of blood sugar glucose and blood pressure slows down the progression of retinopathy.

Diabetic retinopathy , also known as diabetic eye disease DED , [2] is a medical condition in which damage occurs to the retina due to diabetes mellitus. It is a leading cause of blindness in developed countries. Diabetic retinopathy affects up to 80 percent of those who have had diabetes for 20 years or more. It is also the leading cause of blindness in people aged 20 to Diabetic retinopathy often has no early warning signs. Even macular edema , which can cause rapid vision loss, may not have any warning signs for some time. In general, however, a person with macular edema is likely to have blurred vision, making it hard to do things like read or drive.


Diabetic retinopathy can cause a range of symptoms, including blurred vision, difficulty seeing colors, and eye floaters.

Diabetic Retinopathy

The light-sensitive layer of retinal cells converts light into electrical signals which are then sent to the brain where they are turned into the images we see. A brilliant network of tiny blood vessels constantly supplies blood to the retina. Hyperglycemia, a condition where glucose levels in the blood are high, can affect every part of the body, including the precious eyes. The negative impact of hyperglycemia is blurry vision which is a sign of diabetes. Diabetes mellitus causes damage to the blood vessels supplying blood to the retina of the eye. This may lead to blindness. Diabetic retinopathy is caused by hyperglycemia or high blood sugar levels.
