Neovascular Age-Related Macular Degeneration

Brief summary

A retrospective, observational, single-arm, non-randomized cohort study of ocular treatment in nAMD patients in Japan who had records of at least 12 months of follow-up after their first brolucizumab intravitreal injection. Patients who had records of at least 12 months of visits after the first brolucizumab injection (index date) were identified during the index period and were recruited during the data collection/recruitment period.
