Managing diabetic retinopathy means knowing which patients are most at risk – and acting before vision is lost. Drs. Paul Chous, Chris Lopez, and Nate Lighthizer share how the latest research on the RET𝘦𝘷𝘢𝘭 DR Score gives them the clarity and confidence to turn functional insights into informed, actionable care.

Patients with diabetes don’t always comply with prescribed care - and even when they do, improved A1C or reliance on GLP-1s doesn’t always mean reduced retinal risk. In this case, Dr. Jeffrey Calhoun used the RET𝘦𝘷𝘢𝘭 handheld ERG’s DR Score to uncover worsening retinopathy despite controlled blood sugar, helping his patient understand the risk of vision loss and prompting a timely referral for further intervention.

Vision Source doctors, learn how the RET𝘦𝘷𝘢𝘭 can bring deeper clinical insight into your decision-making at this year’s Exchange in Nashville!

Patients with diabetes don't always comply with prescribed courses of treatment, despite structural abnormalities that threaten their vision - instead, they may rely on medication to control their symptoms.
