Current and future management of diabetic retinopathy: a personalized evidence-based approach

Ryan J Fante, Thomas W Gardner & Jeffrey M Sundstrom

Diabetic retinopathy (DR) is the leading cause of new-onset blindness in working-age individuals in the USA and represents a growing worldwide epidemic. Classic risk factors for onset or progression of DR include poor glycemic control, hypertension and hyperlipidemia; however, these factors account for only a small proportion of the risk of DR. New systemic risk factors are emerging, which may allow for personalized risk profiling and targeted treatment by physicians. In addition, early studies of vitreous fluid in patients with DR have resulted in a new paradigm: diabetes causes inflammation in the retina, which is mediated by multiple small signaling molecules that induce angiogenesis and vascular permeability. Future treatment of DR may involve two approaches: early vitreous analysis, followed by drug treatment targeted to the unique vitreous composition of the patient; and collaboration between ophthalmologists and primary care providers to address the unique systemic risk profile of each diabetic patient.
