• Had documented neovascular age-related macular degeneration (nAMD) on or within 3 years before the index injection.
• Used only brolucizumab for at least 12 months (± 45 days) after the index injection, with at least 1 brolucizumab injection given within the first 6 months after the index injection and at least 1 additional brolucizumab injection given at 6-12 months after the index injection.

Exclusion Criteria:

• Had received any other anti-VEGF agent between the index injection and 12-month follow-up.
• Lacked information about the laterality of disease at the time of the index injection.
• Lacked visual acuity assessments on or within 30 days before the index injection or at 6, 9, and 12 months after the index injection (all of the latter ± 45 days).

This was a retrospective, noninterventional cohort study.
