Details and patient eligibility
About
This retrospective study included nAMD patients whose eyes were grouped into the following cohorts, with the overall cohort receiving ≥ 1 brolucizumab injection; the 12-month and 18-month brolucizumab (BRO) cohorts, which consisted of nAMD patient eyes who switched from a previous anti-vascular endothelial growth factor (VEGF) and had ≥3 brolucizumab injections with no other anti-VEGF in the first 12 months (360 days) and 18 months (540 days) of follow-up respectively; and the 12-month and 18-month alternating (ALT) cohorts, which consisted of nAMD patient eyes who switched from a previous anti-VEGF to brolucizumab and had ≥2 brolucizumab injections and ≥1 injection of another anti-VEGF in the first 12 months and 18 months of follow-up, respectively.
