How Diabetes Causes Blindness - Topic Overview

Laser treatments may not always work in treating proliferative retinopathy. If you have retinal detachment or hemorrhages that cannot be repaired, your retinal specialist will need to use a surgical technique to try to restore your vision. This surgical technique, called pars plana vitrectomy, attempts to repair your retina and reduce hemorrhaging. Like many surgical techniques, it has several risks and is much more likely to damage your eye than laser surgery.
Other eye problems
People with diabetes are also at risk for other problems, such as cataracts and glaucoma, that damage your vision. People with diabetes are also at risk for a severe form of glaucoma called neovascular glaucoma. Cataracts are frequently caused by a lifetime of sun exposure, and diabetes only speeds up their formation.
The following table outlines the major causes of blindness in people who have diabetes.
|
Condition |
How it causes vision loss |
Preventive measures |
|---|---|---|
| Diabetic retinopathy | Damages the retina, the section of your eye responsible for capturing visual information |
|
| Glaucoma | Increases pressure in the eye, which results in damage to your retina |
|
| Cataracts | Cloud the lens, the section of your eye responsible for focusing light on your retina |

If you notice problems with your vision, you should immediately seek medical evaluation by an ophthalmologist. Regular eye exams are meant to detect any retinopathy at the nonproliferative stage, where it may still be treated with a good chance of success.
If nonproliferative retinopathy is not detected and treated early, it may progress to proliferative retinopathy. During proliferative retinopathy, your body tries to correct the microaneurysms. To replace blood vessels that have broken or leaked, new blood vessels begin to form. These blood vessels are fragile and may break easily, causing bleeding into the middle of the eye and clouding vision. They also form scar tissue that can pull on the retina and cause the retina to detach from the wall of the eye.
With aggressive management of your condition-keeping hemoglobin A1c levels below 7% and controlling blood pressure-along with regular screening of your vision, you may be able to prevent or delay blindness.
