Introduction to NPDR

The clinician portal provides a central location for eye care specialists to find information on nonproliferative diabetic retinopathy (NPDR), including pathophysiology, diagnosis, and management.

Diabetic retinopathy (DR) is the leading cause of new cases of blindness in adults, a growing problem as the number of people living with diabetes increases.¹ Around 29% of American adults with diabetes have some stage of DR, although many may not be aware of it due to a lack of symptoms.² According to a CDC study, around 15% of the over 4 million Americans with diabetic retinopathy had vision-threatening complications.¹

Understanding DR is critical because it is a key sign of systemic diabetic microvascular complications and may be a sentinel indicator of the impact of diabetes on the patient.¹ Working to improve awareness of DR and access to screening and treatment may reduce the burden of diabetes-related vision loss.¹
