    What are the symptoms of Diabetic Retinopathy ?
    ### Response:
    At first, you will see a few specks of blood, or spots, "floating" in your vision. If spots occur, see your eye care professional as soon as possible. You may need treatment before more serious bleeding or hemorrhaging occurs. Hemorrhages tend to happen more than once, often during sleep.
