To work effectively, the retina needs a constant supply of blood, which it receives through a network of tiny blood vessels. Long term rise in blood sugar levels causes harm to cell in the retina. This situation is called diabetic retinopathy. It is caused by damage to the blood vessels of the light-sensitive tissue at the back of the eye. If not managed properly, it may lead to permanent eye damage.
Diabetic retinopathy is accounted for millions of blinds. With the increase in diabetic cases there is a possibility that more individuals will suffer from it. That is why; every diabetic above 12 years of age should have their eyes examined once a year for signs of damage.
Retinopathy does not cause any noticeable symptoms during initial stages. You may not even realize that your retina is damaged until the later stages. Possible symptoms of retinopathy, often seen in later stages are, blurred vision, shapes floating in field of vision, reduced night vision and sudden blindness.
It is possible to prevent diabetic retinopathy by controlling your diabetes more effectively by taking prescribed medicines on time, losing some weight, and sharing with your doctor the changes you are noticing.
Mild retinopathy can be treated by correcting the blood sugar levels. If you have advanced retinopathy, laser surgery can be used to prevent further damage to your eyes.
