Diabetic Retinopathy

Diabetic retinopathy affects the blood vessels in the retina (the back of the eye). As these blood vessels become weak or damaged, they leak blood and fluid into the retinal tissue. Because the retina is responsible for converting light into signals that are sent to the brain, any damage to the retina will result in vision problems.

Stages of Diabetic Retinopathy

In the early stages of diabetic retinopathy, the retinal blood vessels will begin to swell and leak fluid in small areas. Left undetected, those blood vessels will eventually distort and close, preventing blood from flowing freely. In order to compensate for this lack of blood flow, abnormal blood vessels will actually grow on the inside surface of the retina. These newly formed blood vessels will be fragile and will not supply the retina with the blood flow necessary for healthy vision. They may cause bleeding and scar tissue to form.

Symptoms of Diabetic Retinopathy

Because this disease typically starts slowly, there are usually no symptoms in the early stages. By the time it starts to impact your vision, the disease will be in a later stage of development. Regular eye exams are critical to detecting this disease early so treatment can be administered and vision preserved.

If you are diabetic and are experiencing any of the following symptoms, contact our diabetic eye doctors immediately:

• Dark spots
• Floaters or strings in vision
• Vision loss
• Blurry vision
• Changes in color perception
