Abstract：
:To investigate changes in the size of the population of patients who are receiving long-term, active treatment for neovascular age-related macular degeneration (AMD). This retrospective, observational study included 18,165 patients who received anti-vascular endothelial growth factor injections (3,974 eyes). The injections performed were divided into the following three groups: group 1, injections performed right after the initial diagnosis; group 2, injections performed <24 months; and group 3, injection performed ≥24 months. Time-dependent changes in the proportion of injections in each group were analyzed. The total number of injections markedly increased from 431 in the 1st quarter of 2014 to 1,323 in the 4th quarter of 2018. There were significant changes in the proportion of injections in each group over time (P < 0.001). The proportions of group 1, group 2, and group 3 in the 1st quarter of 2014 were 17.4%, 65.4%, and 17.2%, respectively. The proportions changed to 10.6%, 50.2%, and 39.5% in the 4th quarter of 2018, respectively. The marked increase in the proportions of group 3 may suggest an increase in the patient population that underwent long-term active treatment. The socioeconomic influence of this trend should be considered when establishing future strategies for neovascular AMD.
