Frequent question: What end stage event of diabetic retinopathy leads to blindness?

The fourth and final stage is known as proliferative retinopathy. This is the advanced stage of the disease. Additional new blood vessels will begin to grow in the retina, but they will be fragile and abnormal. Because of this, they can leak blood which will lead to vision loss and possibly blindness.

Can diabetic retinopathy cause sudden blindness?

It’s caused by damage to the blood vessels of the light-sensitive tissue at the back of the eye (retina). At first, diabetic retinopathy might cause no symptoms or only mild vision problems. But it can lead to blindness.

What is the third stage of diabetic retinopathy?

Stage 3: proliferative retinopathy

This means that new blood vessels and scar tissue have formed on your retina, which can cause significant bleeding and lead to retinal detachment, where the retina pulls away from the back of the eye. At this stage: there’s a very high risk you could lose your vision.

Which complication of diabetes can result in blindness?

Diabetes doubles the chances of having glaucoma, which can lead to vision loss and blindness if not treated early. Symptoms depend on which type of glaucoma you have.

What is the leading cause of new onset blindness in diabetic patients?

Diabetic retinopathy, the most common form of diabetic eye disease, is the leading cause of blindness in adults age 20–74. It occurs when diabetes damages blood vessels in the retina.

What is the most advanced or severe stage of diabetic retinopathy?

Proliferative retinopathy is the advanced stage where abnormal new blood vessels grow on the surface of the retina. These vessels may break and bleed into the vitreous, the clear watery gel that fills the eye, and cause severe vision loss.

What can cause sudden eyesight loss?

Common causes of sudden vision loss include eye trauma, blockage of blood flow to or from the retina (retinal artery occlusion or retinal vein occlusion), and pulling of the retina away from its usual position at the back of the eye (retinal detachment).

What happens diabetic retinopathy?

Over time, diabetes damages small blood vessels throughout the body, including the retina. Diabetic retinopathy occurs when these tiny blood vessels leak blood and other fluids. This causes the retinal tissue to swell, resulting in cloudy or blurred vision. Diabetic retinopathy usually affects both eyes.

What are the stages of diabetic retinopathy?

When these blood vessels thicken, they can develop leaks, which can then lead to vision loss. The four stages of diabetic retinopathy are classified as mild, moderate, and severe nonproliferative and proliferative.

How quickly does retinopathy progress?

In the severe form of nonproliferative diabetic retinopathy, it can progress to proliferative diabetic retinopathy up to 60% of the time within 12 months. When it gets to proliferative diabetic retinopathy, we see the beginnings of neovascularization.

What causes blurred vision in diabetes?

In a person with diabetes, fluid can move into and out of the eye due to high blood sugar levels. This can cause the lens of the eye to swell. As the shape changes, blurriness results, because the lens is the part that focuses light onto the back of the eye.

Does insulin affect eyesight?

You may also get blurred vision when you start insulin treatment. This is due to shifting fluids, but it generally resolves after a few weeks. For many people, as blood sugar levels stabilize, so does their vision.

How does diabetes cause diabetic retinopathy?

Diabetic retinopathy is caused by high blood sugar due to diabetes. Over time, having too much sugar in your blood can damage your retina — the part of your eye that detects light and sends signals to your brain through a nerve in the back of your eye (optic nerve). Diabetes damages blood vessels all over the body.

When does diabetic retinopathy occur?

Typically, diabetic patients will develop diabetic retinopathy after they have had diabetes for between 3-5 years. In the early stages, diabetic retinopathy will not affect sight, but if it progresses, eventually sight will be affected.

Is diabetes the number one cause of blindness?

Diabetes is the leading cause of new cases of blindness in adults. This is a growing problem as the number of people living with diabetes increases, so does the number of people with impaired vision. Diabetes can cause a disease of the eye called diabetic retinopathy (DR).

Is blindness due to diabetes reversible?

Can diabetic retinopathy be reversed? No, but it doesn’t have to lead to blindness, either. If you catch it early enough, you can prevent it from taking your vision. That’s why it’s vital to have regular visits with an Ophthalmologist or Optometrist who’s familiar with diabetes and retina treatment.
