Diabetes affects the entire body, including the eyes. High blood sugar levels can damage blood vessels in the retina. If left untreated, diabetic retinopathy can lead to blindness. Major risk factors for diabetic retinopathy include time since diagnosis, control of blood sugar, and family history. In our comprehensive eye exams, Dr. Tarr has a direct view of your blood vessels and can detect signs of diabetes during your exam.
Our diabetic patients will receive a special eye exam at least once a year that focuses on eye disease related to diabetes. During your diabetic eye examination, Dr. Tarr will focus on the health of your retina and the integrity of the blood vessels inside your eyes. At Tarr Eye & Vision Center, we use advanced diagnostic technology to help us detect eye diseases before they can cause vision loss or damage. Through digital imaging, we can detect the slightest changes in your retinal health and recommend treatment right away. Dr. Tarr will conduct a few tests to determine your eye health, including:
Dr. Tarr has a direct view of your blood vessels and can detect early damage to those vessels and the nerve layer in the back of your eye. This damage is called diabetic retinopathy. These are the most common sight threatening diabetic eye concerns.
Diabetic retinopathy is caused by the effects of high blood sugar on the blood vessels in the retina. In the beginning, diabetic retinopathy might show few or no symptoms. However, if these blood vessels begin to leak into the retina, blurred vision or even blindness can occur. Waiting to deal with these leaky vessels is a lot like having a water leak on the floor of your home. The longer the fluid stays there the more irreversible damage is done. In fact, this is the most common cause of blindness due to diabetes.
Diabetic macular edema can be caused if diabetic retinopathy is left untreated. With diabetic macular edema, the fluid from the blood vessels can also start to leak into the macula (the central part of the retina), which allows you to read and recognize facial features. Without treatment, diabetic macular edema can lead to blindness.
