At first, people with diabetic retinopathy will not notice any symptoms. As the disease gets worse, they may notice blurred (模糊的) vision, black spots or flashing lights. As time goes on, it can progress to blindness. Everyone with diabetes is at risk for diabetic retinopathy, and the risk increases the longer you've had diabetes.
Fortunately, you can reduce your risk. If you do not have diabetes, but think you may be at risk for this condition, visit your doctor to be screened for diabetes. If you do have diabetes:
● Have frequent eye check-ups.
● Make sure that you monitor your blood sugar frequently and use your medications as recommended by your doctor. There is evidence to show that keeping your blood sugar under tight control can slow down eye damage.
● If you have high blood pressure, follow your recommended diet and medications to keep it under control. If you are not sure whether you have high blood pressure, or whether your blood pressure is under control, discuss this with your doctor.

Milk That Paid a Medical Bill
One day, a poor boy who was selling goods from door to door to pay his way through school found he had only one thin dime (10分钱) left, and he was hungry.
He decided he would ask for a meal at the next house. However, he lost his nerve when a lovely young woman opened the door. Instead of a meal he asked for a drink of water. She thought he looked hungry so she brought him a large glass of milk. He drank it slowly, and then asked, "How much do I owe you?" "You don't owe me anything," she replied. "Mother has taught us never to accept pay for a kindness." He said, "Then I thank you from my heart."
As Howard Kelly left that house, he not only felt stronger physically, but his faith in God and man was strong also. He had been ready to give up and quit.
Years later that young woman became critically ill. The local doctors were baffled (感到困惑). They finally sent her to the big city, where they called in specialists to study her rare disease. Dr. Howard Kelly was called in for the consultation. When he heard the name of the town she came from, a strange light filled his eyes. Immediately he rose and went down the hall of the hospital to her room. Dressed in his doctor's gown he went in to see her. He recognized her at once. He went back to the consultation room determined to do his best to save her life. From that day he gave special attention to the case. After a long struggle, the battle was won.
Dr. Kelly requested the business office to pass the final bill to him for approval. He looked at it; then wrote something on the edge and the bill was sent to her room. She feared to open it, for she was sure it would take the rest of her life to pay for it all. Finally she looked, and something caught her attention on the side of the bill. She read these words: "Paid in full with one glass of milk." Tears of joy flooded her eyes as her happy heart prayed: "Thank You, God, that Your love has spread abroad through human hearts and hands."
