Diabetic retinopathy is one of the most common causes of sight loss among people of working age.
It occurs when diabetes affects small blood vessels, damaging the part of the eye called the retina. When the blood vessels in the central area of the retina (the macula) are affected, it’s known as diabetic maculopathy.
People with diabetes should also see their optician every two years for a regular eye test. Diabetic eye screening is specifically for diabetic retinopathy and can’t be relied upon for other conditions.
