Addressing Unmet Needs in Diabetic Retinopathy

Diabetic retinopathy (DR), the primary retinal vascular complication of diabetes mellitus, is a progressive disease and a major cause of impaired vision and blindness, especially among individuals who are of working age. Early detection and treatment of DR can prevent 50% to 70% of its associated blindness. However, fewer than half of all US adults with diabetes adhere to guideline-recommended eye-screening schedules. Patients with DR typically have no symptoms in the early stage of the disease and may not seek medical evaluation until DR advances and results in vision impairment. These delays in diagnosis and treatment may result in visual impairment that is permanent and cannot be reversed. Although the direct medical costs of DR are substantial, the indirect costs of visual impairment with respect to loss of productivity, increased nursing home admissions, and decreased quality of life are far more copious. Greater adherence to eye screening guidelines among patients with diabetes is required to facilitate prompt diagnosis and early treatment of DR, and in doing so, reduce the resulting vision loss and economic burden associated with DR.
