Evolving Treatment Patterns in Diabetic Macular Edema Between 2015 and 2020

Abstract

Purpose: To explore the recent evolution of diabetic macular edema (DME) treatment practice patterns over 5 years among retina specialists in the United States. Methods: This retrospective analysis assessed 306 700 eyes with newly diagnosed DME from the Vestrum Health database between January 2015 and October 2020. The year-over-year and cumulative 5-year distributions of eyes treated with antivascular endothelial growth factor (anti-VEGF) agents, steroids, focal laser, or any combination and those of untreated eyes were calculated. Changes from baseline visual acuity were assessed. Results: Yearly treatment patterns changed significantly from 2015 (n = 18056) to 2020 (n = 11042). The proportion of untreated patients declined over time (32.7% vs 27.7%; P < .001), the use of anti-VEGF monotherapy increased (43.5% vs 61.8%; P < .001), the use of focal laser monotherapy declined (9.7% vs 3.0%; P < .001), and the use of steroid monotherapy remained stable (0.9% vs 0.7%; P = 1.000). Of eyes that maintained follow-up for 5 years (from 2015 to 2020), 16.3% were untreated while 77.5% were treated with anti-VEGF agents (as monotherapy or combination therapy). Vision gains in treated patients remained approximately stable from 2015 (3.6 letters) to 2020 (3.5 letters). Conclusions: From 2015 to 2020, treatment patterns for DME evolved toward greater anti-VEGF monotherapy, stable steroid monotherapy, less laser monotherapy, and fewer untreated eyes.
