Abstract: Purpose: To identify time-specific factors associated with loss to follow-up (LTFU) in the early to medium term after initiating anti-vascular endothelial growth factor (VEGF) treatment in patients with neovascular age-related macular degeneration (nAMD) in Japan. Methods: The study had a retrospective multicenter case–control design and was performed across 16 specialist retinal facilities in Japan. Patients diagnosed with nAMD at their initial visit who initiated treatment between January 2017 and December 2020 were included. Patient characteristics were analyzed to identify factors associated with LTFU within 3 months (very early), 3 months to 1 year (early), and 1 year to 2 years (medium term) after starting treatment. Results: Data for 2389 patients with nAMD were analyzed. The very early, early, and medium-term LTFU rates were 6.8%, 13.8%, and 21.2%, respectively. Stepwise regression analysis identified factors that were significantly associated with LTFU at a very early stage to be greater central retinal thickness at baseline and a prior treatment history, those associated with early LTFU to be worse baseline best-corrected visual acuity (BCVA), anti-VEGF treatment combined with photodynamic therapy, and a follow-up period that overlapped with the COVID-19 pandemic, and that associated with medium-term LTFU to be worse BCVA at 3 months. LTFU in any period within 3 months to 2 years was more likely in patients aged >80 years, and LTFU very early within 3 months was more likely in those aged 1 was a risk factor for LTFU within 3 months and 1 year, whereas LTFU was significantly less likely in patients with good baseline BCVA (
