BACKGROUND AND OBJECTIVE: To characterize vascular endothelial growth factor (VEGF) inhibitor treatment patterns in patients with diabetic macular edema (DME) using a Medicare Standard Analytic Files Part B or Outpatient Claims database to understand treatment frequency and DME persistence.

PATIENTS AND METHODS: A retrospective analysis of treatment patterns for patients diagnosed with DME receiving their first anti-VEGF injection was performed.

RESULTS: The average number of anti-VEGF injection claims for DME per patient rose from 3.1 to 4.6 per year (mean: 4.2). Within 1 year of diagnosis, 46% of patients received their final DME diagnosis (mean: 1.9 anti-VEGF claims), and 65% of patients received their final anti-VEGF treatment for DME. Patients who received treatment for DME through years 2 and 3 submitted a mean of four and 7.2 anti-VEGF claims, respectively.

CONCLUSION: VEGF inhibitor treatment was less frequent than in landmark trials, but did resolve DME in a proportion of patients. [Ophthalmic Surg Lasers Imaging Retina. 2016;47:258-267.].
