  https://en.wikipedia.org/wiki/Diabetic_retinopathy

  Diabetic retinopathy affects up to 80 percent of those who have had both type 1 and type 2 diabetes for 20 years or more. […] The longer a person has diabetes, the higher their chances of developing diabetic retinopathy. Each year in the United States, diabetic retinopathy accounts for 12% of all new cases of blindness. It is also the leading cause of blindness in people aged 20 to 64. […] Nearly all people with diabetes develop some degree of retina damage („retinopathy”) over several decades with the disease. For many, that damage can only be detected by a retinal exam, and has no noticeable effect on vision. […] Over time, progressive retinal damage may appear on a retinal exam, first with small bulges in retinal blood vessels called microaneurysms. […] Eventually, many progress to a stage where new blood vessels grow throughout the retina. These new blood vessels often break and bleed. Minor bleeding can cause dark floating spots obstructing vision; major bleeding can completely block vision.

  Moderate NPDR As the disease progresses, blood vessels that provide important nourishment to the retina may swell and lose their ability to transport blood. […] During this stage, the appearance of the retina may change as a result of these symptoms. […] Untreated moderate NPDR may lead to diabetic macular edema, or swelling in the macular region of the retina, which can cause serious vision loss. […] Severe NPDR In this stage, the blood supply to the retina is disrupted, leading to more damage in the blood vessels. […] Proliferative Diabetic Retinopathy (PDR) At this advanced stage of DR, the retina secretes growth factors (substances that stimulate cell growth) to generate new blood vessels. […] Because they’re fragile, these new blood vessels are more likely to leak and bleed, producing scar tissue that can shrink and lead to retinal detachment in which the retina pulls away from underlying tissue.

  In proliferative diabetic retinopathy, damage to the retina stimulates the growth of new blood vessels. The new blood vessels grow abnormally, sometimes leading to bleeding (hemorrhage) or scarring. Extensive scarring may cause detachment of the retina. Proliferative diabetic retinopathy results in greater loss of vision than does nonproliferative diabetic retinopathy. It can result in total or near-total blindness due to a large hemorrhage into the vitreous humor (the jellylike substance that fills the back of the eyeball, also called the vitreous) or to a type of retinal detachment called traction retinal detachment.

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. Diabetic retinopathy is classified into two types. Non-proliferative diabetic retinopathy (NPDR) is the early stage of the disease in which symptoms will be mild or nonexistent. Proliferative diabetic retinopathy (PDR) is the more advanced form of the disease. If left untreated, PDR can cause severe vision loss and even blindness. 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.

  People with diabetes can have an eye disease called diabetic retinopathy. This is when high blood sugar levels cause damage to blood vessels in the retina. These blood vessels can swell and leak. Or they can close, stopping blood from passing through. Sometimes abnormal, new blood vessels grow on the retina. All of these changes can steal your vision. […] You can have diabetic retinopathy and not know it. This is because it often has no symptoms in its early stages. As diabetic retinopathy gets worse, you will notice symptoms such as: seeing an increasing number of floaters, having blurry vision, having vision that changes sometimes from blurry to clear, seeing blank or dark areas in your field of vision, having poor night vision, noticing colors appear faded or washed out, losing vision. Diabetic retinopathy symptoms usually affect both eyes. […] With NPDR, tiny blood vessels leak, making the retina swell. When the macula swells, it is called macular edema. This is the most common reason why people with diabetes lose their vision. […] PDR is very serious, and can steal both your central and peripheral (side) vision.

  In its advanced stages, diabetic retinopathy can cause irreversible blindness. During any stage of diabetic retinopathy, a condition known as macular edema can develop. Macular edema is the buildup of fluid in the macula, the light-sensitive part of the retina that allows objects to be seen with great detail. As the macula swells, vision becomes blurred. […] As the disorder worsens, more and more blood vessels are affected. By the time a patient has proliferative retinopathy, the body is creating new blood vessels to replace the ones that are blocked. The problem is that the new blood vessels have very thin walls. If they leak blood, severe vision loss or blindness can result. […] Other than controlling blood pressure, blood cholesterol and blood sugar, treatment is not needed during the first three stages of diabetic retinopathy. The fourth stage, proliferative retinopathy, is treated with a laser surgery known as scatter laser treatment. During the procedure, the abnormal blood vessels are ablated, causing them to shrink.

  Diabetic retinopathy is an eye disease caused by diabetes mellitus. It affects the retina, the part of the eye that lets us see. Diabetes hurts the retinas tiny blood vessels and can cause swelling and leaking of fluid into the eye. Extra retinal blood vessels can grow, which damages eyesight. Diabetic retinopathy is the leading cause of blindness in people 20 to 70 years old. All people with diabetes type 1 or 2 are at risk. Almost half of Americans with diabetes have some stage of diabetic retinopathy. There are four stages of diabetic retinopathy. The first is early mild nonproliferative retinopathy, with small balloon-like swollen areas in tiny retinal blood vessels. Then moderate nonproliferative retinopathy occurs, with blocked blood vessels. Severe nonproliferative retinopathy follows (more blood vessels are blocked, and new vessels grow). In the advanced stage (proliferative retinopathy), new abnormal, fragile blood vessels grow along the retina and watery soft gel (vitreous gel) inside the eye.

  The longer a person has diabetes and the worse their blood sugar control is, the greater their risk of getting diabetic retinopathy, Dr. Khan says. […] If you have an earlier stage of diabetic retinopathy, treatment may not be needed right away and your doctor will monitor your eyes closely. Managing blood sugar appropriately can help slow or stop the progression of this eye disease. […] The longer diabetic retinopathy goes untreated, the greater your risk of permanent vision loss. […] A diagnosis of severe NPDR or PDR will most likely require immediate surgery. […] Because diabetes is a lifelong condition, additional retinal damage and vision loss are possible even after surgery. […] Effective blood sugar control can usually slow the progression of mild or moderate diabetic retinopathy. […] There is no cure for diabetic retinopathy, but mild levels can be treated with careful diabetes management, says Rishi Singh, MD, a retina specialist and the president of Cleveland Clinic Florida, Martin Health, in Stuart, Florida.

  People with diabetes can have an eye disease called diabetic retinopathy. This is when high blood sugar levels cause damage to blood vessels in the retina. These blood vessels can swell and leak. Or they can close, stopping blood from passing through. Sometimes abnormal, new blood vessels grow on the retina. All of these changes can steal your vision. […] You can have diabetic retinopathy and not know it. This is because it often has no symptoms in its early stages. As diabetic retinopathy gets worse, you will notice symptoms such as: seeing an increasing number of floaters, having blurry vision, having vision that changes sometimes from blurry to clear, seeing blank or dark areas in your field of vision, having poor night vision, noticing colors appear faded or washed out, losing vision. Diabetic retinopathy symptoms usually affect both eyes. […] With NPDR, tiny blood vessels leak, making the retina swell. When the macula swells, it is called macular edema. This is the most common reason why people with diabetes lose their vision. […] PDR is very serious, and can steal both your central and peripheral (side) vision.

  Poor oxygenation of tissues drives the formation of new blood vessels throughout the retina, resulting in the proliferative stage of disease. […] The major risk factors for developing diabetic retinopathy are duration of diabetes, poor blood sugar control, and to a lesser extent high blood pressure. […] Five years after diabetes diagnosis, around 25% of those with type 1 diabetes have some degree of diabetic retinopathy, while 2% have proliferative diabetic retinopathy. By 15 years after diagnosis, that increases to 80% with some retinopathy, and 25% with proliferative disease. […] Both chronically high blood sugar (measured by a high HbA1c) and highly variable blood sugar are associated with developing diabetic retinopathy. […] Diabetic retinopathy is caused by prolonged high blood glucose damaging the small blood vessels of the retina, though the mechanism by which this occurs is unknown. […] The condition typically develops about 10-15 years after receiving the diagnosis of diabetes mellitus.

  Diabetic retinopathy is an eye disorder that causes damage to the blood vessels in the retina (i.e., the light-sensitive tissue at the back of the eye). The condition is a leading cause of blindness in adults, particularly if left untreated. […] Symptoms of the disorder may include distorted vision, the inability to distinguish colors, dark spots or floaters in the field of vision, and vision loss in advanced stages. […] The progress of diabetic retinopathy can be slowed down by maintaining stable blood sugar levels. […] Diabetic retinopathy symptoms are exacerbated by high blood pressure and high cholesterol levels. […] Diabetic retinopathy must be diagnosed and treated early in the disease process to manage the disorder and prevent vision loss effectively.
