Over time, a persistently high blood sugar level can damage these blood vessels in 3 main stages: background retinopathy — tiny bulges develop in the blood vessels, which may bleed slightly but do not usually affect your vision pre-proliferative retinopathy — more severe and widespread changes affect the blood vessels, including more significant bleeding into the eye proliferative retinopathy — scar tissue and new blood vessels, which are weak and bleed easily, develop on the retina; this can result in some loss of vision However, if a problem with your eyes is picked up early, lifestyle changes and treatment can stop it getting worse.
Am I at risk of diabetic retinopathy? You're at a greater risk if you: have had diabetes for a long time have a persistently high blood sugar blood glucose level have high blood pressure have high cholesterol are pregnant are of Asian or Afro-Caribbean background By keeping your blood sugar, blood pressure and cholesterol levels under control, you can reduce your chances of developing diabetic retinopathy.

The lenses within our eyes are clear structures that help provide sharp vision—but they tend to become cloudy impairmenr we age.
People with diabetes are Doabetic 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 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.
The needle is about the thickness of a human hair. Laser treatment, also called photocoagulation, creates tiny burns inside the eye with a beam of light.
This method treats leaky blood vessels and extra fluid, called edema. Your doctor usually provides this treatment during several office visits, using medicine to numb your eyes.
Laser treatment can keep eye disease from getting worse, which is important to prevent vision loss or blindness. There are two types of laser treatment :. Vitrectomy is a surgery to remove the clear gel that fills the center of the eye, called the vitreous gel. The procedure treats problems with severe bleeding or scar tissue caused by proliferative diabetic retinopathy.
Scar tissue can force the retina to peel away from the tissue beneath it, like wallpaper peeling away from a wall. A retina that comes completely loose, or detaches, can cause blindness. During vitrectomy, a clear salt solution is gently pumped into the eye to maintain eye pressure during surgery and to replace the removed vitreous.
Vitrectomy is done in a surgery center or hospital with pain medicine. In a surgery center or hospital visit, your doctor can remove the cloudy lens in your eye, where the cataract has grown, and replace it with an artificial lens. People who have cataract surgery generally have better vision afterward.
After your eye heals, you may need a new prescription for your glasses. Your vision following cataract surgery may also depend on treating any damage from diabetic retinopathy or macular edema.
To prevent diabetic eye disease, or to keep it from getting worse, manage your diabetes ABCs: your A1c, blood pressure, and cholesterol; and quit smoking if you smoke.
Read more information on how to manage diabetes. Also, have a dilated eye exam at least once a year—or more often if recommended by your eye care professional.
These actions are powerful ways to protect the health of your eyes—and can prevent blindness. The sooner you work to manage your diabetes and other health conditions, the better. Ask your eye care professional to help you find a low vision and rehabilitation clinic.
Special eye care professionals can help you manage vision loss that cannot be corrected with glasses, contact lenses, medicine, or surgery.

Diabetic retinopathy vision impairment -
Treating diabetic retinopathy can repair damage to the eye and even prevent blindness in most people. Treatment can start before your sight is affected, which helps prevent vision loss.
Options include:. A cataract is the clouding of the normally clear lens in your eye. One reason is that high blood sugar can cause deposits to build up in the lenses and make them cloudy.
Other risk factors include high blood pressure, having obesity, too much sun exposure over time, and smoking. Using brighter lights in your home and anti-glare sunglasses outside can help early on.
If your cataracts get in the way of doing everyday activities, it may be time for surgery. The good news is the surgery is very safe, and most people have better vision afterwards!
Glaucoma is a group of eye diseases that damage the optic nerve, usually because of too much pressure in the eye. People with diabetes are twice as likely to develop open-angle glaucoma, the most common type. Diabetes can also cause neovascular glaucoma. This happens sometimes with diabetic retinopathy when new and abnormal blood vessels grow on the iris the colored part of the eye.
The new vessels can block off the flow of fluid out of the eye, which raises eye pressure. Treatment options include medicines, laser treatment, and surgery. Talk to your eye doctor about what choices are best for you.
Eye problems are common in people with diabetes, but treatments can be very effective. Only your eye doctor can diagnose eye diseases, so make sure to get a dilated eye exam at least once a year.

Changes may include: Blurring Spots Flashes Blind spots Distortion Difficulty reading or doing detail work. Diabetic Retinopathy Treatment Treating diabetic retinopathy can repair damage to the eye and even prevent blindness in most people.
Options include: Laser therapy also called laser photocoagulation. This creates a barrier of scar tissue that slows the growth of new blood vessels.
Medicines called VEGF inhibitors, which can slow down or reverse diabetic retinopathy. Removing all or part of the vitreous vitrectomy. Reattachment of the retina for retinal detachment, a complication of diabetic retinopathy.
Injection of medicines called corticosteroids. Other Eye Diseases. Keep your blood sugar levels in your target range as much as possible. Over time, high blood sugar not only damages blood vessels in your eyes, it can also affect the shape of your lenses and make your vision blurry.
Keep your blood pressure and cholesterol levels in your target range to lower your risk for eye diseases and vision loss. Also good for your health in general! Quit smoking. Quitting lowers your risk for diabetes-related eye diseases and improves your health in many other ways too.
Further worsening of advanced diabetic retinopathy can lead to retinal detachment, which requires urgent surgical intervention and can result in permanent, irreversible vision loss if not promptly treated.
As blood glucose directly damages retinal blood vessels, there is strong epidemiological evidence that blood sugar control translates to decreased incidence and severity of diabetic retinopathy.
In order to reduce the cardiovascular and microvascular complications of diabetes , which include retinopathy, nephropathy kidney disease , and neuropathy nerve damage , it is recommended that people achieve and maintain a normal blood pressure. Blood pressure reduction can delay the onset of diabetic retinopathy , but it is unclear if controlling blood pressure can alter the course of established diabetic retinopathy.
Similarly, managing cholesterol is advocated for overall diabetes management, but it is not clear whether doing so reduces the risk of diabetic retinopathy.
An ophthalmologist can diagnose and begin to treat diabetic retinopathy before sight is affected. In general, people with type 1 diabetes should see an ophthalmologist once a year, beginning five years after the onset of their disease.
People with type 2 diabetes should see an ophthalmologist for a retinal examination soon after their diagnosis, and then schedule annual exams after that.
You may need to see an ophthalmologist more frequently if you are pregnant or have more advanced diabetic retinopathy. As mentioned above, damage to the blood vessels deprives the retina of oxygen. Insufficient oxygen leads to production of a signal protein called vascular endothelial growth factor VEGF.
VEGF and its role in eye disease were first discovered at Harvard Medical School. Currently, there are medications that can bind VEGF and subsequently improve the symptoms of diabetic retinopathy.
In some people, steroids injected directly into the eye may also improve diabetic macular edema. In some advanced cases of proliferative diabetic retinopathy the most advanced form of diabetic retinopathy , patients may require retinal laser therapy or retinal surgery to stop or slow bleeding and leakage, to shrink damaged blood vessels, or to remove blood and scar tissue.
