Diabetes & Your Eyes
What People with Diabetes in Denver Should Know About Diabetic Eyes
People living with diabetes live with many hardships and issues. It is safe to say that more attention to details of health is simply required for diabetic patients. According the American Diabetes Association there are over 23.6 million children and adults that suffer from diabetes. This constitutes an alarming 7.8% of the total US population. What many do not realize about diabetes is the potential damage that this disease can do to one's vision. One manner in which diabetes can affect the vision is when blood sugar levels increase significantly and change the lens of the eye, resulting in blurred vision. It takes several weeks after lowering the blood sugar to normal before the vision can clear completely. Another way in which diabetes involves the eye and decreases vision is the development of diabetic retinopathy (disease of the retina). It is estimated that 25% of people with diabetes have some level of retinopathy. Diabetic patients should get an eye exam every year to monitor overall eye health.
Diabetic eye disease typically involves a progression of disease related events that occur as a result of the duration of the disease. All of the diabetic eye problems or issues occur from involvement of the blood vessels in the eye, except the previously discussed changes in the lens. The cascade of events become visible in the retina fairly early in the disease process and can be detected -- diabetic retinopathy. In the normal eye, the light entering the eye strikes the retina, is changed into eletrical energy and is transmitted to the brain by the optic nerve. When the retina is altered, the vision is usually impaired. Diabetes often causes other eye diseases to be more severe (glaucoma) or begin earlier (cataracts). The routine complete eye exam can recognize the changes in the retina and appropriate steps can be initiated to decrease the effects of the disease.
Diabetic retinopathy begins in the tiny blood vessels that nourish the retina (the capillaries). The capillaries dilate and start to leak, fluid(serum) or tiny amounts of blood, which cause swelling of the retina and resultant distortion of the vision --background or nonproliferative diabetic retinopathy. Over time more serious forms of diabetic retinopathy may develope -- proliferative diabetic retinopathy. The chance of having some form of diabetic retinopathy increases the longer a person has had diabetes.
Research has shown that severe visual loss from diabetic retinopathy can be prevented or delayed by maintaining strict control of one's sugar level in the blood. More advanced forms of diabetic eye disease can be treated by laser treatment or administration of medication to inhibit swelling of or bleeding into the retina. The earlier the recognition of diabetic retinopathy, the more successful treatment can be. Annual eye exams are a must for diabetics.
If you are a diabetic you can significantly reduce the risk of developing diabetic retinopathy by using common sense and taking good care of yourself. The following list is an example of some good things that diabetics can practice that will help maintain proper eye health.
- Get regular eye exams
- Keep blood sugar under control.
- Monitor blood pressure and keep it under control
- Eat healthy and maintain proper diet.
- Exercise as directed by your physician
If vision becomes blurred, it becomes difficult to read or do close work, or if vision becomes spotty or hazy, see you eye doctor.

Diabetes Myths Pertaining to Eye Problems
Many people that come into eye care facilities with diabetes often think that if they get diabetes that it cannot cause blindness. If diabetes is not detected and is allowed go un-noticed people can loose their vision. Patients with diabetic retinopathy can have treatments to avoid going blind.
