Diabetic retinopathy is the leading cause of blindness among people with both type 1 and type 2 diabetes, affecting millions each year in the U.S. Having regular vision evaluations and eye exams is the best way to detect diabetic retinopathy in its early stages so it can be treated, and the risk of permanent vision loss can be prevented. East Texas Eye Associates is dedicated to providing complete eye care for patients with a wide range of vision disorders and diseases, including diabetic retinopathy. If you have diabetes or you're at risk for diabetes, here's what you should know about diabetic retinopathy.
The retina contains special cells that react to light. The tiny blood vessels in and around the retina begin to develop weak spots or swell. Over time, these weak areas can leak blood and other fluids into the retina in which then block light and causes images to appear blurry and indistinct. In some types of diabetic retinopathy new blood vessels form to compensate for the vessels that are damaged. Sometimes, these new vessels wind up breaking, forming scar tissue that tugs on the retina. Sometimes abnormal new blood vessels grow on the retina. Without proper treatment, the retina can become completely detached from the eye, resulting in permanent blindness.
In the very early stages of the disease, many patients have few or even no symptoms. That's why it's so very important to have regular vision exams to help spot the signs of the disease so treatment can begin before permanent vision loss occurs. As the disease progresses to more serious stages, it can cause symptoms like:
- Blurred vision.
- An increase in the number of "floaters," squiggly lines or dots that appear to "float" in front of your field of vision.
- Dark spots in your field of vision.
- Reduced color vision - specifically, colors may appear less vibrant or distinct.
Dr. Duncan is skilled in diagnosing and treating DR in patients throughout Deep East Texas. Diagnosis of DR begins with a comprehensive eye exam to test your vision and evaluate your retina. Depending on the stage of the disease, you may be able to manage your symptoms and control the disease just by better management of your blood sugar levels. In more advanced stages, injections of special medicines can shrink new blood vessels. Also, laser treatment can be helpful in eliminating scar tissue to reduce the risk of retinal detachment.
