Diabetes causes changes in the veins, arteries and capillaries that carry blood throughout your body. These changes can harm your vision. There are two types of diabetic retinopathy that can lead to vision loss: proliferative diabetic retinopathy and non proliferative diabetic retinopathy.
Diabetes and Your Eyes
If you have diabetes you are at risk of vision loss from Diabetes Retinopathy (damage to the very small blood vessels on the back of the eye). However, good blood glucose levels and blood pressure and regular screening can greatly reduce the risk of complications. Diabetes Retinopathy can occur regardless of the type of diabetes you have, your age, or even the control you have over your blood-glucose levels.
For this reason, everyone who has diabetes should have their eyes checked regularly. Begin when diabetes is first diagnosed, and then yearly after that. If the damage is detected before it has affected your sight, treatment can prevent vision loss. Where vision loss has already occurred, treatment can only stop it from getting worse.
