In diabetic retinopathy, high blood sugar levels damage blood vessels in the retina and can cause swelling, leakage or complete closure. In some cases, abnormal blood vessels grow on the retina. All these changes can cause vision loss.
Fortunately, treatment advancements have decreased blindness among diabetics and have increased the possibility of retaining useful vision. At Texas Retina, our physicians work with each patient to determine the best treatment plan for their specific situation.
