Eye Damage

High blood glucose (sugar) levels cause damage to the blood vessels and the retina, which is the area at the back of the eye responsible for detecting light and sending messages to the brain to form pictures. The retina is fragile and covered in blood vessels.

Damaged blood vessels in the retina can leak and become blocked which is known as diabetic retinopathy. Diabetic retinopathy can be treated by laser therapy, injections into the eye, and in some rare cases surgery.
