Why is diabetes danger for eyes ?

Diabetes can be dangerous for the eyes because it can cause damage to the blood vessels in the retina, the light-sensitive tissue at the back of the eye. This condition is called diabetic retinopathy. If left untreated, diabetic retinopathy can lead to blindness. Diabetes can also increase the risk of other eye problems, such as cataracts and glaucoma. It is important for people with diabetes to have regular eye exams to check for early signs of these problems and to receive treatment as needed.
