How Does Diabetic Retinopathy Affect Vision – People with diabetes can develop an eye disease called diabetic retinopathy. This is when high blood sugar levels cause damage to the blood vessels in the retina. These blood vessels may swell and leak. Or they can close, preventing blood from passing through. Sometimes abnormal new blood vessels grow in the retina. All these changes can steal your vision.
This is the first stage of diabetic eye disease. Many people with diabetes suffer from it. With NPDR, small blood vessels leak, causing the retina to swell. When the macula swells, it is called macular edema. It is the most common cause of blindness in people with diabetes. Also with NPDR, blood vessels in the retina may become blocked. This is called macular ischemia. When this happens, the blood cannot reach the macula. Sometimes tiny particles called exudate can form in the retina. These can also affect your vision. If you have NPDR, your vision will be blurry.
PDR is the more advanced stage of diabetic eye disease. This happens when the retina begins to grow new blood vessels. This is called neovascularization. These fragile new blood vessels often bleed into the vitreous. If they bleed just a little, you may see some dark floaters. If they are bleeding profusely, it can block any vision. These new blood vessels can create scars. Scar tissue can cause problems with the macula or lead to a detached retina. PDR is very serious, and can steal your central and peripheral (side) vision. This increases the risk of serious vision problems, including cataracts, glaucoma, diabetic retinopathy, and double vision. When your blood sugar gets out of control, your eyes swell, causing nearsightedness. For this reason, corrective lens prescription changes are more accurate when an eye exam is performed when your blood sugar is under control. in diabetes Below is a list of diabetes-related eye diseases that the Retina Health Center treats:
Diabetic retinopathy is a general term used for eye complications caused by diabetes in the retina. The blood vessels that supply blood to the retina are said to weaken. It is the leading cause of vision loss in adults aged 20 to 64, and affects 90% of patients with diabetes for 15 years or more. Juvenile diabetes is more likely to develop diabetic retinopathy in childhood. Pregnancy or high blood pressure can make the condition worse. Fortunately, most vision loss can be prevented with regular eye exams and early treatment.
These tools are fragile and can break. A ruptured blood vessel can stretch and pull on the retina, pulling it away from the inner wall. There is no pain, and partial loss or even blindness is possible.
The best way to prevent the development of diabetic retinopathy is to control blood sugar, cholesterol and blood pressure. Regular follow-up with a doctor, physical activity and a healthy diet are also important.
Successful treatment of diabetic eye disease depends greatly on your willingness to participate fully in your treatment. Regular eye exams are essential to maintaining vision. It is easier to prevent vision loss due to diabetes than to restore vision after loss.
If you notice a decrease in vision or an increase in the number of new floaters (small snakes or spider webs entering your field of vision) get an immediate evaluation at the Retina Health Center.
Regular eye exams are an important part of preventing vision loss as a result of diabetes. Diabetic patients under the age of 30 should undergo an annual examination starting no later than five years after the diagnosis of diabetes. An annual eye exam is recommended for diabetics over the age of 30. However, if there is evidence of damage to your eyes, more frequent exams may be needed. Pregnant women should have their eyes checked at least once during the first three months of pregnancy.
In the retina clinic, special equipment is used to examine the eyes. If there is evidence of diabetic retinopathy, a fluorescein test may be necessary. During this test, a fluorescent dye is injected into the blood vessels, and pictures are taken of the structure of the blood vessels in the retina. These are used to assess the condition of the vessel and are a “guide” for laser treatment when laser treatment is necessary. Another common test is ocular coherence tomography (OCT), which creates a cross-sectional image of the retina. This test will determine if there is a tumor in your retina that may benefit from treatment.

Although regular monitoring of blood glucose levels and blood pressure is necessary to prevent the progression of the disease, if treatment for diabetic retinopathy is recommended, there are several options at the same time at the Retina Health Center.
If diabetic retinopathy is detected early, in-office laser therapy is often used to prevent further damage. Patients will visit our retina clinic offices in Fort Myers or Naples, where the treatment will be performed. To reduce blood vessel leakage in patients with diabetic macular edema, lasers are used to close the leaky blood vessels. Laser therapy is also used to stop the growth of abnormal blood vessels in patients with proliferative diabetic retinopathy.
In severe cases of proliferative diabetic retinopathy, bleeding occurs in the vitreous, the gel-like substance in the center of the eye. In some cases it is clear and no further treatment is needed. However, if this is not clear, a vitrectomy – the removal of the cloudy object – can be performed surgically.
In addition to lasers and surgery, there are several medications that can be used to treat diabetic retinopathy. These include Lucentis, Eylea, Ozurdex and the ILUVIEN permanent implant. In addition, Avastin and/or Triamcinolone can be used off-label to treat advanced diabetic retinopathy, and can restore vision in some patients. If these medications help, your doctor will discuss them with you later. Diabetic retinopathy – is it reversible? December 11, 2018 | by dr.

Light-sensitive cells convert light into electrical signals, which are sent to the brain where they are converted into the images we see. The retina is constantly supplied with blood by small, shiny blood vessels.
Hyperglycemia, a condition that increases the level of glucose in the blood, can affect any part of the body, including the precious eyes. A negative effect of hyperglycemia is blurred vision which is a sign of diabetes.
If the sugar level is not maintained at a normal level, the dizziness does not go away. Diabetes causes damage to the blood vessels that supply blood to the retina. It can cause blindness.
Diabetic retinopathy is caused by hyperglycemia or high blood sugar levels. In this situation, the blood vessels in the retina are damaged and the blood clots or leaks. This leads to vision loss if untreated and untreated. Diabetic retinopathy usually takes years to progress to the stage where it can lead to total blindness.
According to statistics from the World Health Organization (WHO), it is estimated that diabetic retinopathy accounts for about 5% of blindness in the world. As the prevalence of diabetes increases, so does the risk of developing diabetic retinopathy. The number of people with diabetic retinopathy is expected to increase to approximately 592 million by 2035.
In countries like India, the prevalence of diabetes has increased significantly and about 62.4 million people in India suffer from diabetes. A pooled analysis of 22,896 people with diabetes from 35 population-based studies in Australia, the United States, Europe and Asia showed that the prevalence of diabetic retinopathy was 34.6%.
Diabetic retinopathy usually affects both eyes. Early stages of diabetic retinopathy usually do not show any signs or symptoms. As the complication progresses, it can lead to:
Vitreous hemorrhage: This occurs when a new blood vessel begins to bleed into the vitreous fluid. When this difficulty is low, you may see floaters. However, with severe bleeding, the blood fills the space and completely blocks vision. This complication takes several weeks or months until the retina is damaged.
Glaucoma: Diabetic retinopathy also causes new blood vessels in the front of the eye. This causes an increase in pressure in the eye and interferes with the normal flow of the liquid. Glaucoma can damage the optic nerve and can cause permanent blindness.
Response: When damaged blood vessels pull the retina away from its supporting cells, a retinal detachment occurs. In this case, you may initially see floaters and flashes of light, and then the vision is completely blurred.
