Diabetic Eye Disease:
How much do you know?
Do you know that diabetic eye disease is a leading cause of blindness? If you have diabetes, do you know how to reduce your risk of visual loss? To determine what your Eye-Q is, answer the following questions.
- People with diabetes are more likely than people without diabetes to develop certain eye diseases.
Choose TRUE or FALSE
True. Diabetic eye disease includes diabetic retinopathy—a leading cause of blindness in adults—cataract, and glaucoma. The longer someone has diabetes, the more likely he or she will develop diabetic eye disease.
- Diabetic eye disease usually has early warning signs.
Choose TRUE or FALSE
False. Often there are none in the early stages of the disease. Vision may not change until the disease becomes severe.
- People with diabetes should have yearly eye examinations.
Choose TRUE or FALSE
True. Everyone with diabetes should get an eye examination through dilated pupils at least once a year. Because diabetic eye disease usually has no symptoms, regular eye exams are important for early detection and timely treatment.
- Diabetic retinopathy is caused by changes in the blood vessels in the eye.
Choose TRUE or FALSE
True. In some people, blood vessels in the retina may swell and leak fluid. In other people, abnormal new blood vessels grow on the surface of the retina.
- People with diabetes are at low risk for developing glaucoma.
Choose TRUE or FALSE
False. Glaucoma is almost twice as likely to occur in people with diabetes than in those without the disease. Glaucoma can usually be treated with medications or laser or other surgery.
- Laser surgery can be used to halt the progression of diabetic retinopathy.
Choose TRUE or FALSE
True. In laser surgery, a special beam of light is used to shrink the abnormal blood vessels or seal leaking blood vessels. Laser surgery has been proved to reduce the five-year risk of vision loss from advanced diabetic retinopathy by more than 90 percent.
- People with diabetes should have regular eye examinations through dilated pupils.
Choose TRUE or FALSE
True. An eye examination through dilated pupils is the best way to detect diabetic eye disease, in which drops are used to enlarge the pupils. This allows the eye care professional to see more of the inside of the eye to check for signs of the disease.
- Cataracts are common among people with diabetes.
Choose TRUE or FALSE
True. People with diabetes are twice as likely to develop cataracts and to develop them at an earlier age than are those without diabetes. Cataracts can usually be treated with surgery.
- People who have good control of their diabetes are not at high risk for diabetic eye disease.
Choose TRUE or FALSE
False. Even with good control of blood glucose, there is still a risk of developing diabetic eye disease. However, studies show that careful management of blood sugar levels slows the onset and progression of diabetic retinopathy.
- The risk of blindness from diabetic eye disease can be reduced.
Choose TRUE or FALSE
True. With early detection and timely treatment, the risk of blindness from diabetic eye disease can be reduced.
