In the Diabetes Control and Complications Trial, people on standard diabetes treatment got retinopathy four times as often as people who kept their blood sugar levels close to normal. In people who already had retinopathy, the condition progressed in the tight-control group only half as often. Patients with diabetes are at an increased risk of developing eye diseases that can lead to vision loss and blindness, such as diabetic retinopathy, cataracts and glaucoma. 

In fact, diabetes is actually the leading cause of blindness in the United States. Diabetic eye conditions often develop without any noticeable vision loss or pain, so significant damage may already be done to the eye by the time patients notice any symptoms. For this reason, it is important for diabetic patients to have their eyes examined at least once a year. Early detection of eye disease can help prevent permanent damage.

Diabetic-related eye problems develop from high blood sugar levels, which can cause damage to blood vessels in the eye. More than 40 percent of those with diabetes will develop some form of eye disease in their life. The risk of developing eye problems can be reduced through regular eye exams and by keeping blood sugar levels under control through a healthy diet and regular exercise.

 

Facts About Diabetic Eye Diseases

All forms of diabetic eye disease have the potential to cause severe vision loss and blindness.While diabetics struggle with a high sugar count in the blood along with insufficient insulin production, it is actually the lack of oxygen in the blood that causes eye problems and leads to vision loss.

Diabetic retinopathy involves changes to retinal blood vessels that can cause them to bleed 

or leak fluid, distorting vision .Diabetic eye conditions develop in the retina as a result of micro vascular abnormalities.The tiny blood vessels within the retina develop micro aneurysms and begin to leak blood. As new blood vessels develop, they also leak blood and can cause hemorrhages and permanent damage to the retina.

Symptoms of Diabetic Eye Diseases

The disease often progresses unnoticed until it affects vision. Bleeding from abnormal retinal blood vessels can cause the appearance of “floating” spots. These spots sometimes clear on their own. But without prompt treatment, bleeding often recurs, increasing the risk of permanent vision loss. If DME occurs, it can cause blurred vision.Diabetic eye conditions can be detected through a comprehensive eye exam.

 A comprehensive eye exam involves a visual acuity test to measure vision at various distances, and a dilated eye exam to examine the structures of the eye for any signs of disease. 

During this test, your doctor can examine the retina and optic nerve with a special magnifying lens. Tonometry may also be performed during a comprehensive eye exam to measure the pressure inside the eye with a special instrument. Eye exams should be performed at least once a year or as soon as any potential problems are detected in order to ensure the early detection of any serious conditions. Early detection is the strongest protection against diabetic eye diseases.

 What is of Diabetic Retinopathy

Diabetic retinopathy, the most common diabetic eye disease, occurs when blood vessels in the retina change. Sometimes these vessels swell and leak fluid or even close off completely. In other cases, abnormal new blood vessels grow on the surface of the retina. It can also cause growth of abnormal new blood vessels on the surface of the retina. There are four stages of diabetic retinopathy that begin with the occurrence of micro aneurysms and eventually lead to 

 the presence of abnormal blood vessels on the surface of the retina  that can easily leak fluid and cause severe vision loss and even blindness.The fluid can also leak into the center of the macula and cause swelling and blurred vision, a condition known as macular edema.

The risk of developing macular edema increases as diabetic retinopathy progresses. Diabetic retinopathy usually affects both eyes. People who have diabetic retinopathy often don't notice changes in their vision in the disease's early stages. But as it progresses, diabetic retinopathy usually causes vision loss that in many cases cannot be reversed. 

Treatment of Diabetic Eye Conditions

To make matters worse, a significant number of cases of diabetes and diabetic eye disease go undetected or untreated because people fail to have routine comprehensive eye exams as recommended by their optometrist or ophthalmologist.Treatment for early stages of diabetic retinopathy and other conditions usually focuses on maintaining levels of blood sugar, blood pressure and blood cholesterol, in order to prevent any permanent damage from occurring. For more advanced stages of the condition, laser surgery is often effective in shrinking the abnormal blood vessels through more than 1,000 laser burns in the area of the retina. This procedure, known as scatter laser treatment, usually requires two or more sessions in order to fully remove the blood vessels.

Macular edema can also be treated through a laser procedure, called focal laser treatment, which places hundreds of laser burns in the area of retinal leakage to reduce the amount of fluid in the retina. This treatment only requires one session.Laser treatments can be performed in your doctor's office. Anesthetic eye drops will be used to minimize pain during the procedure. Patients may experience blurry vision for the remainder of the day, and should rest at home. It is important for patients to realize that these procedures cannot cure diabetic eye conditions, but rather help reduce vision loss and slow the progression for patients with more advanced cases. Most laser and non-laser treatments for diabetic eye disease depend on the severity of the eye changes and type of vision problems you have.
