Who is affected by diabetic retinopathy
Diabetic retinopathy is the leading cause of new cases of
vision loss in adults between ages 20 and 74.1 The
prevalence of the disease varies between those with
type 1 diabetes and those with
type 2 diabetes.
Among people who have
type 1 diabetes:
- After 5 years, about 25% have
retinopathy.1
- After 10 years, 60% have
retinopathy.1
- After 15 years, 98% have
retinopathy, and of those, 26% have the proliferative form of the
disease.2
- After 20 years, almost all have
retinopathy.1 More than half (53%) have the
proliferative form.2
Among people who have type 2 diabetes:
- At diagnosis, about 21% have retinopathy.1 People with type 2 diabetes are more likely to have had the
disease for several years before they are actually diagnosed. As a result, the
time between diagnosis of diabetes and initial development of retinopathy may
be shorter in people with type 2 diabetes.
- After 15 years, about
60% to 85% have retinopathy.2
