High blood sugar from diabetes can cause damage to the blood vessels in the retina. This damage is called retinopathy.

Diabetic retinopathy is a complication of diabetes that weakens the blood vessels that supply nourishment to the retina (the light-sensitive lining in the back of the eye where vision is focused). When these weak vessels leak, swell, or develop thin branches, vision loss occurs. In its advanced stages, the disease can cause blurred or cloudy vision, floaters and blind spots – and, eventually, blindness. This damage may be irreversible.

A medical eye examination is the only way to find changes inside your eye. If diabetic retinopathy is found, a test called flourescein angiography may be ordered. This test can detect where fluid may be leaking by injecting a dye into your arm and taking photos of this dye going through the eye. Laser surgery may be recommended to maintain your current vision and prevent any further loss of vision. Multiple laser treatments over time are sometimes necessary to treat diabetic retinopathy. Laser surgery does not cure diabetic retinopathy and doesn't always prevent further loss of vision. You may continue to lose vision.

Fortunately, diabetic retinopathy is preventable. People with diabetes are most susceptible to developing it, but your risk is reduced if you follow your prescribed diet and medications, exercise regularly, control your blood pressure, and avoid alcohol and cigarettes. Regular eye exams are an integral part of making sure your eyes are healthy. A full range of diagnostics and treatment for diabetic patients is available here at Eye Center of Central Maine.
