Diabetes is a very common illness in the United States. It affects approximately 10% of the population and one in four people do not realize they have this disease. It is caused by elevated blood glucose or blood sugar that is too high. This elevated blood sugar can affect many organs in the body and can have disastrous effects on your vision. The tissue in the back of the eye called the retina can be impaired by elevated blood sugar. When the eyes are involved this is called diabetic retinopathy. The disease can cause the blood vessels to leak fluid and cause swelling in the area of the retina called the macula. Early detection is imperative to saving vision in patients with diabetic retinopathy. Premier Eye Physicians offers the latest diagnostic testing to detect this disease early in its course.
