Purpose: To evaluate the clinical course of patients who had completed 14 ranibizumab or aflibercept monocular treatments.
Methods: Retrospective medical record analysis was performed to 24 patients who were diagnosed with monocular neovascular age-related macular degeneration and had completed 14 ranibizumab or aflibercept monocular injections, allowed by the Korean National Health Care system. Time to completion was measured along with the percentage and timing of medication switch. Best-corrected visual acuity (BCVA) was measured at the time of diagnosis, after 3-loading injections, and the time of completion. Additionally, we searched for any other factors that had influenced the time to completion.
Results: The average time to completion of 14 injections was 32.3 ± 6.2 months (21?48 months). The switching was performed in 17 eyes (70.8%), and it was done after 9.4 ± 2.1 injections (4?14 injections) with prior medication. After 14 injections, the BCVA improved in 6 eyes (25.0%), unchanged in 8 eyes (33.3%), and worsened in 10 eyes (41.7%). Complete resolution of intraretinal fluid and subretinal fluid after 3 loading injections were observed in 20 eyes, and it was significantly related to time to the first recurrence and time to the completion of 14 injections (p = 0.007, r = 0.583).
Conclusions: The average time to completion of 14 injections was 32.3 months, and switching of medication was performed in 70.8%. Longer time to the first recurrence was related to longer completion time. This study will provide useful facts when informing the patients their future treatment plans under the Korean Health Care system.
