Diabetic Retinopathy: Current Concepts and Future Directions

Dear Colleagues,

Currently the world faces a challenge of epidemic proportions called diabetes mellitus (DM). According to several estimates, in 2021 10.5% (537 million) of the adult population suffered from DM. Approximately half of these do not even know that they have DM. The number of people worldwide with DM will rise to 643 million by the year 2030. DM is no longer a disease of rich developed countries. Changes in dietary habits, obesity and physical inactivity are responsible for spreading this epidemic into the developing countries. All of these individuals will be at risk of developing diabetic retinopathy (DR).

Over the past decade, new pharmacological treatments for diabetic macular edema, proliferative diabetic retinopathy and nonproliferative diabetic retinopathy have been approved. Novel biomarkers have been identified in different imaging modalities, particularly in OCTA and SD-OCT. Artificial intelligence algorithms have aided the identification of these biomarkers.
