People with diabetes are also at risk for other diabetic eye diseases, such as:
• Cataract. A clouding of the eye's lens.
People with diabetes are twice as likely to develop a cataract. Cataracts often can be treated with surgery.
• Glaucoma . An increase in fluid pressure inside the eye that leads to optic nerve damage and loss of vision.
People with diabetes are also twice as likely as other adults to develop glaucoma. Glaucoma can often be treated with medications or laser or other forms of surgery.
Diabetic eye disease refers to a group of eye problems that may occur in people with diabetes as a complication. All can cause severe vision loss or even blindness. Diabetic eye disease can often be treated before vision loss occurs. All people with diabetes should have a dilated eye examination at least once a year.
Diabetic eye diseases include the following:
Diabetic retinopathy is the most common eye disease in people with diabetes.
Diabetic retinopathy is the leading cause of blindness in American adults. It is caused by changes in the blood vessels of the retina, the light-sensitive lining of the eye. In some people with diabetic retinopathy, retinal blood vessels may swell and leak fluid, while in others, abnormal new blood vessels grow on the surface of the retina. These changes may result in vision loss or blindness.
Diabetic retinopathy cannot be completely avoided, but the risk can be greatly reduced. Better control of blood sugar level slows the onset and progression of retinopathy and reduces the need for laser surgery for severe retinopathy.
A person with an early stage of diabetic retinopathy may be asymptomatic and without pain. Vision may not change until the disease progresses.
A condition called macular edema may occur when the macula, a part of the retina, swells from the leaking fluid and causes blurred vision. When new vessels grow on the surface of the retina, they can bleed into the eye and decrease your vision.
Anyone with diabetes is at risk for diabetic retinopathy. The longer a person has diabetes, the more likely he or she will develop diabetic retinopathy.
Although diabetic retinopathy cannot be prevented, the risk of developing it can be reduced by:
Specific treatment for diabetic retinopathy will be determined by your doctor based on:
Diabetic retinopathy is often treated with laser surgery to shrink the abnormal blood vessels or to seal the leaking ones.
