What eye problems can diabetes cause? Some common diabetes eye problems include: Diabetic retinopathywhich is the leading cause of blindness in American adults.

It affects blood vessels in the retina the light-sensitive layer of tissue in the back of your eye. The blood vessels may swell and leak fluid into your eye. If it's not treated, it can cause serious problems such as vision loss and retinal detachmentwhere the retina is pulled away from its normal position at the back of your eye.

Diabetic macular edema DMEwhich happens when blood vessels in the retina leak fluid into the macula a part of the retina needed for sharp, central vision. This usually develops in people who already have other signs of diabetic retinopathy.

Glaucomaa group of eye diseases that can damage the optic nerve the bundle of nerves that connects the eye to the brain.

Glaucoma from diabetes happens when the blood vessels in the front of your eye are damaged, and new blood vessels grow near the iris the colored part of your eye.

The blood vessels block the space where fluid drains from your eye. This causes fluid to build up and pressure to increase inside your eye. Cataractwhich happen when the clear lens in the front of your eye becomes cloudy.

Cataracts are common as people age. But people with diabetes are more likely to develop cataracts younger and faster than people without diabetes.

Researchers think that high glucose levels cause deposits to build up in the lenses of your eyes. Who is more likely to develop diabetic eye problems? But your risk of developing it is higher if you: Have had diabetes for a long time Don't have good control over your high blood sugar or high blood pressure Are pregnant Have high blood cholesterol Smoke tobacco What are the symptoms of diabetic eye problems?

Call your doctor right away if you notice any of these symptoms: Many new spots or dark wavy strings floating in your vision floaters Flashes of light A dark shadow over part of your vision, like a curtain Vision loss Eye pain or redness Talk with your doctor if you have these symptoms, even if they come and go: Spots or dark wavy strings floating in your vision Blurry or wavy vision Vision that changes a lot Trouble seeing colors How are diabetic eye problems diagnosed?

What are the treatments for diabetic eye problems? Some of the treatments include: Lasers to stop blood vessels from leaking Injections shots in the eye to stop new, leaky blood vessels from growing Surgery to remove blood and scar tissue or replace a cloudy lens Eye drops to lower fluid pressure in the eye But these treatments aren't cures.

Depending on their recent blood sugar control and last diabetes examination with their PCP or endocrinologist, it may be necessary to refer patients back to those providers sooner than scheduled so that they can consider changes in treatment.

These findings must be in the absence of neovascularization, which would indicate PDR. Figure 3. This patient with type 2 diabetes has severe NPDR. Patients with severe NPDR should be monitored using both macular OCT and fluorescein angiography to detect any DME or early neovascularization.

These patients are at a high risk of disease progression and permanent vision loss, and they are most likely experiencing neuropathy elsewhere at this point. These patients require immediate referral to a retina specialist for further testing and treatment.

Peripheral neovascularization is usually treated with laser panretinal photocoagulation PRP, Figure 4. Figure 4. This patient with type 2 diabetes was treated with laser PRP in the periphery for PDR in both eyes. Until their disease stabilizes, these patients need to be monitored monthly by a retina specialist.

But diabetes can also make you more likely to develop several other eye conditions: Cataracts. Having diabetes makes you 2 to 5 times more likely to develop cataracts. It also makes you more likely to get them at a younger age.

Learn more about cataracts. Open-angle glaucoma. Having diabetes nearly doubles your risk of developing a type of glaucoma called open-angle glaucoma. Learn more about glaucoma.

What are the symptoms of diabetic retinopathy? What other problems can diabetic retinopathy cause? Diabetic retinopathy can lead to other serious eye conditions: Diabetic macular edema DME.

Over time, about 1 in 15 people with diabetes will develop DME. DME happens when blood vessels in the retina leak fluid into the macula a part of the retina needed for sharp, central vision.

This causes blurry vision. Neovascular glaucoma. Diabetic retinopathy can cause abnormal blood vessels to grow out of the retina and block fluid from draining out of the eye. This causes a type of glaucoma a group of eye diseases that can cause vision loss and blindness.

Learn more about types of glaucoma. The laser is used to obliterate some of the ischemic peripheral retina in order to decrease VEGF release and induce regression of neovascularization. If successful, vitreous hemorrhage and tractional retinal detachment may be averted.

Sometimes the proliferative disease is advanced and there is blood filling the eye and preventing application of laser or scar tissue that wrinkles the retina or pulls it off the eyewall tractional retinal detachment.

In these situations, surgery may be necessary see vitrectomy for more information. In some cases, anti-VEGF injections into the eye can also be used to induce regression of neovascularization.

DRCR protocol S showed that the anti-VEGF drug ranibizumab was noninferior to PRP in managing patients with PDR.

In situations where PRP is not possible, such as in the presence of vitreous hemorrhage, anti-VEGF injections may help to improve the likelihood of clearance of the hemorrhage.

Follow-up is crucial for patients receiving anti-VEGF injections alone as this therapy does not appear to provide long-term involution of the neovascularization after the injections are halted, whereas PRP generally has long-lasting effects.

Thus, in a patient who is, for any reason, unlikely to return for follow-up, anti-VEGF injections alone should not be the treatment of choice and PRP should be done.

However, a large case-control study has demonstrated no difference between injections alone vs. PRP alone in the odds of TRD. Anti-VEGF injections may sometimes be used in concert with PRP when rubeosis and neovascular glaucoma are present. Another common scenario is using anti-VEGF injections initially in eyes with vitreous hemorrhage that is too dense to permit PRP then later performing laser once the hemorrhage has adequately cleared.

Anti-VEGF injections are also sometimes given prior to vitrectomy surgery in selected cases to lower the risk of intraoperative hemorrhage. The goal of surgery is to remove blood and scar tissue from the retinal surface and to place laser treatment as needed.

Intraoperatively, intraocular gas or silicone oil may be needed to maintain reattachment of the retina to the underlying layers and eyewall. There is always the low, but real risk of infection of the eyeball endophthalmitis with any injection of drugs into the eye or with eye surgery.

There is also the risk of cataract progression with retinal surgery. Vitrectomy accelerates the rate of cataract formation. ETDRS studies show that the stage of retinopathy is correlated with progression to more advanced stages or retinopathy and visual loss.

Food and Drug Administration FDA for treatment of diabetic macular edema — faricimab-svoa Vabysmo , ranibizumab Lucentis and aflibercept Eylea. A fourth drug, bevacizumab Avastin , can be used off-label for the treatment of diabetic macular edema. These drugs are injected using topical anesthesia.

The injections can cause mild discomfort, such as burning, tearing or pain, for 24 hours after the injection. Possible side effects include a buildup of pressure in the eye and infection.

These injections will need to be repeated. In some cases, the medication is used with photocoagulation. This laser treatment, also known as focal laser treatment, can stop or slow the leakage of blood and fluid in the eye.

During the procedure, leaks from abnormal blood vessels are treated with laser burns. Focal laser treatment is usually done in your doctor's office or eye clinic in a single session.

If you had blurred vision from macular edema before surgery, the treatment might not return your vision to normal, but it's likely to reduce the chance of the macular edema worsening. Panretinal photocoagulation. This laser treatment, also known as scatter laser treatment, can shrink the abnormal blood vessels.

During the procedure, the areas of the retina away from the macula are treated with scattered laser burns. The burns cause the abnormal new blood vessels to shrink and scar. It's usually done in your doctor's office or eye clinic in two or more sessions.

Your vision will be blurry for about a day after the procedure. Some loss of peripheral vision or night vision after the procedure is possible. While treatment can slow or stop the progression of diabetic retinopathy, it's not a cure.

Because diabetes is a lifelong condition, future retinal damage and vision loss are still possible. Even after treatment for diabetic retinopathy, you'll need regular eye exams. At some point, you might need additional treatment. Explore Mayo Clinic studies testing new treatments, interventions and tests as a means to prevent, detect, treat or manage this condition.

Several alternative therapies have suggested some benefits for people with diabetic retinopathy, but more research is needed to understand whether these treatments are effective and safe.

Let your doctor know if you take herbs or supplements. They can interact with other medications or cause complications in surgery, such as excessive bleeding.

It's vital not to delay standard treatments to try unproven therapies. Early treatment is the best way to prevent vision loss. The thought that you might lose your sight can be frightening, and you may benefit from talking to a therapist or finding a support group.

Ask your doctor for referrals. If you've already lost vision, ask your doctor about low-vision products, such as magnifiers, and services that can make daily living easier. The American Diabetes Association ADA recommends that people with type 1 diabetes have an eye exam within five years of being diagnosed.

If you have type 2 diabetes, the American Diabetes Association ADA advises getting your initial eye exam at the time of your diagnosis. If there's no evidence of retinopathy on your initial exam, the ADA recommends that people with diabetes get dilated and comprehensive eye exams at least every two years.

If you have any level of retinopathy, you'll need eye exams at least annually. Ask your eye doctor what he or she recommends. The ADA recommends that women with diabetes have an eye exam before becoming pregnant or during the first trimester of pregnancy and be closely followed during the pregnancy and up to one year after giving birth.

Pregnancy can sometimes cause diabetic retinopathy to develop or worsen. On this page. Alternative medicine. Coping and support.

Preparing for your appointment. Fluorescein angiography After your eyes are dilated, a dye is injected into a vein in your arm. Optical coherence tomography OCT With this test, pictures provide cross-sectional images of the retina that show the thickness of the retina.

Early diabetic retinopathy If you have mild or moderate nonproliferative diabetic retinopathy, you might not need treatment right away. Advanced diabetic retinopathy If you have proliferative diabetic retinopathy or macular edema, you'll need prompt treatment.

Depending on the specific problems with your retina, options might include: Injecting medications into the eye.

This procedure uses a tiny incision in your eye to remove blood from the middle of the eye vitreous as well as scar tissue that's tugging on the retina. It's done in a surgery center or hospital using local or general anesthesia. Request an appointment. More Information.

Can medicine help prevent diabetic macular edema? Clinical trials. Here's some information to help you get ready for your eye appointment.

What you can do Write a brief summary of your diabetes history, including when you were diagnosed; medications you have taken for diabetes, now and in the past; recent average blood sugar levels; and your last few hemoglobin A1C readings, if you know them.

List all medications, vitamins and other supplements you take, including dosages. List your symptoms, if any. Include those that may seem unrelated to your eyes. Ask a family member or friend to go with you, if possible.

Someone who accompanies you can help remember the information you receive. Also, because your eyes will be dilated, a companion can drive you home. List questions for your doctor.

For diabetic retinopathy, questions to ask your doctor include: How is diabetes affecting my vision? Do I need other tests? Is this condition temporary or long lasting?

What treatments are available, and which do you recommend? What side effects might I expect from treatment? I have other health conditions. How can I best manage them together? If I control my blood sugar, will my eye symptoms improve?

What do my blood sugar goals need to be to protect my eyes? Can you recommend services for people with visual impairment?

Don't hesitate to ask other questions you have. What to expect from your doctor Your doctor is likely to ask you questions, including: Do you have eye symptoms, such as blurred vision or floaters? How long have you had symptoms? In general, how well are you controlling your diabetes?

What was your last hemoglobin A1C? Do you have other health conditions, such as high blood pressure or high cholesterol? Have you had eye surgery?

What is diabetic retinopathy?

Treatment of diabetic retinopathy varies depending on the extent of the disease. People with diabetic retinopathy may need laser surgery to seal leaking blood vessels or to discourage other blood vessels from leaking. A doctor of optometry might need to inject medications into the eye to decrease inflammation or stop the formation of new blood vessels.

People with advanced cases of diabetic retinopathy might need a surgical procedure to remove and replace the gel-like fluid in the back of the eye, called the vitreous. Surgery may also be needed to repair a retinal detachment. This is a separation of the light-receiving lining in the back of the eye.

Laser treatment photocoagulation is used to stop the leakage of blood and fluid into the retina. A laser beam of light can be used to create small burns in areas of the retina with abnormal blood vessels to try to seal the leaks. Treatment for diabetic retinopathy depends on the stage of the disease.

The goal of any treatment is to slow or stop the progression of the disease. In the early stages of non-proliferative diabetic retinopathy, regular monitoring may be the only treatment.

Following your doctor's advice for diet and exercise and controlling blood sugar levels can help control the progression of the disease.

Injections of medication in the eye are aimed at discouraging the formation of abnormal blood vessels and may help slow down the damaging effects of diabetic retinopathy. If the disease advances, the abnormal blood vessels can leak blood and fluid into the retina, leading to macular edema.

Laser treatment photocoagulation can stop this leakage. A laser beam of light creates small burns in areas of the retina with abnormal blood vessels to try to seal the leaks.

Widespread blood vessel growth in the retina, which occurs in proliferative diabetic retinopathy, can be treated by creating a pattern of scattered laser burns across the retina. This causes abnormal blood vessels to shrink and disappear. With this procedure, some side vision may be lost in order to safeguard the central vision.

Acanthamoeba is one of the most common organisms in the environment. Although it rarely causes infection, when it does occur, it can threaten your vision. Amblyopia—also known as lazy eye—is the loss or lack of development of clear vision in one or both eyes. Forgot username or password?

These damaged blood vessels can cause vision loss: Fluid can leak into the macula, the area of the retina responsible for clear central vision. Although small, the macula is the part of the retina that allows us to see colors and fine detail. The fluid causes the macula to swell, resulting in blurred vision.

In an attempt to improve blood circulation in the retina, new blood vessels may form on its surface. These fragile, abnormal blood vessels can leak blood into the back of the eye and block vision. Diabetic retinopathy is classified into two types. Non-proliferative diabetic retinopathy Non-proliferative diabetic retinopathy NPDR is the early stage of the disease in which symptoms will be mild or nonexistent.

Proliferative diabetic retinopathy Proliferative diabetic retinopathy PDR is the more advanced form of the disease. Risk factors for diabetic retinopathy include: Diabetes. People with type 1 or type 2 diabetes are at risk for developing diabetic retinopathy.

The longer a person has diabetes, the more likely he or she is to develop diabetic retinopathy, particularly if the diabetes is poorly controlled. Hispanics and African Americans are at greater risk of developing diabetic retinopathy. Medical conditions.

People with other medical conditions, such as high blood pressure and high cholesterol, are at greater risk. Pregnant women face a higher risk of developing diabetes and diabetic retinopathy.

If a woman develops gestational diabetes, she has a higher risk of developing diabetes as she ages. Family History. Symptoms Symptoms of diabetic retinopathy include: Seeing spots or floaters. Blurred vision. Having a dark or empty spot in the center of your vision.

Difficulty seeing well at night. Diagnosis Diabetic retinopathy can be diagnosed through a comprehensive eye examination. Testing, with emphasis on evaluating the retina and macula, may include: Patient history to determine vision difficulties, presence of diabetes, and other general health concerns that may be affecting vision.

Visual acuity measurements to determine how much central vision has been affected. Refraction to determine if a new eyeglass prescription is needed. Evaluation of the ocular structures, including the evaluation of the retina through a dilated pupil.

Measurement of the pressure within the eye. Supplemental testing may include: Retinal photography or tomography to document the current status of the retina. Get an online second opinion from one of our experts without having to leave your home.

Get a Second Opinion. MyChart UChicago Medicine. Diabetic retinopathy is the most common diabetic eye disease and a leading cause of blindness in American adults. It is caused by changes in the blood vessels of the retina, the light-sensitive tissue at the back of the eye necessary for good vision.

In some people with diabetic retinopathy, retinal blood vessels may leak fluid and cause swelling of the retina in the macular region, which adversely affects central vision. In other people, abnormal new blood vessels grow on the surface of the retina and can cause severe bleeding into the eye.

If you have diabetic retinopathy, at first you may not notice changes to your vision. But over time, diabetic retinopathy can get worse and cause vision loss.

Diabetic retinopathy usually affects both eyes. During the first three stages of diabetic retinopathy, no treatment is needed, unless you have macular edema.

To prevent progression of diabetic retinopathy, people with diabetes should control their levels of blood sugar, blood pressure and blood cholesterol. Proliferative diabetic retinopathy is treated with laser surgery. At the Irwin Retina Center, laser surgery is done as an outpatient procedure and requires no surgical incision.

A strong light beam is aimed onto the retina to treat and shrink the abnormal vessels. If the bleeding is severe, you may need a surgical procedure called a vitrectomy. During a vitrectomy, blood is removed from the center of the eye. If you have macular edema, laser surgery may also be used.

In this case, the laser beam is used to seal the leaking blood vessels. If you have macular edema in both eyes and require laser surgery, generally only one eye will be treated at a time, usually several weeks apart.

Focal laser treatment stabilizes vision. Laser treatment reduces the risk of vision loss by 50 percent. In a small number of cases, if vision is lost, it can be improved. Finding diabetic retinopathy early is the best way to prevent vision loss.

With timely treatment, the majority of those with advanced diabetic retinopathy can be saved from going blind. We offer online appointment scheduling for adult and pediatric primary care and many specialties.

Often there are no symptoms in the early stages of the disease, nor is there any pain. Don't wait for symptoms. Be sure to have a comprehensive dilated eye exam at least once a year. Blurred vision may occur when the macula — the part of the retina that provides sharp central vision — swells from leaking fluid.

This condition is called macular edema. If new blood vessels grow on the surface of the retina, they can bleed into the eye and block vision. At first, you will see a few specks of blood, or spots, "floating" in your vision. If spots occur, see your eye care professional as soon as possible.

You may need treatment before more serious bleeding occurs.

Diabetic retinopathy ophthalmology

Diabetic retinopathy ophthalmology -

Meenakashi Gupta, MD: NYEE Is Leading the Way in Advanced Imaging to Treat Diseases of the Retina. Diabetes is a disease that occurs when your blood glucose sugar is too high. Blood glucose is your main source of energy and comes from the food you eat. Normally, a hormone called insulin—that is produced by the pancreas—keeps the level of glucose in our blood in check.

However, in type 1 diabetes, the body does not make insulin, and in type 2 diabetes, the body does not respond normally to the insulin it makes.

If you have diabetes, it can attack many parts of the body, including the kidneys diabetic nephropathy , nerve endings diabetic neuropathy , and the back of the eye diabetic retinopathy. Many people with diabetes also have high cholesterol and triglycerides in their blood, which increases the risk of having a heart attack or stroke.

Diabetic retinopathy develops as the blood vessels of the retina become damaged over time by elevated blood sugar. While the smallest blood vessels throughout the body are affected, the retina is the earliest tissue to show injury due to its rapid metabolism.

Diabetic patients must have regular eye exams to detect the earliest features of the disease before their vision begins to suffer; early recognition and proactive intervention are key to preserving eyesight.

Comprehensive management and regular monitoring of your diabetes is the first—and perhaps the most important—step in the treatment process. That includes getting your hemoglobin A1c level, blood pressure, and lipid levels under the best possible control.

Multiple studies have demonstrated that when these indicators are as close to normal as possible, you are less likely to develop diabetic retinopathy—and more likely to slow its progress if it does occur.

At first, you will see a few specks of blood, or spots, "floating" in your vision. If spots occur, see your eye care professional as soon as possible. You may need treatment before more serious bleeding occurs. Hemorrhages tend to happen more than once, often during sleep.

If left untreated, proliferative retinopathy can cause severe vision loss and even blindness. The earlier you receive treatment, the more effective it will be. The Stages of Diabetic Retinopathy Diabetic retinopathy has 4 stages: Mild Nonproliferative Retinopathy.

At the initial stage, micro-aneurysms occur. They are small areas of balloon-like swelling in the retina's tiny blood vessels. Moderate Nonproliferative Retinopathy. As the disease progresses, some blood vessels that nourish the retina are blocked.

Severe Nonproliferative Retinopathy. Many more blood vessels are blocked, depriving several areas of the retina with their blood supply.

These areas of the retina send signals to the body to grow new blood vessels for nourishment. Proliferative Retinopathy.

At this advanced stage, the signals sent by the retina for nourishment trigger the growth of new blood vessels. This condition is called proliferative retinopathy. These new blood vessels are abnormal and fragile. They grow along the retina and along the back surface of the clear, vitreous gel that fills the inside of the eye.

By themselves, these blood vessels do not cause symptoms or vision loss. However, they have thin, fragile walls. If they leak blood, severe vision loss and even blindness can result.
