摘要
Purpose To evaluate the difference in the treatment burden among different types of neovascular age-related macular degeneration (AMD). Methods This retrospective, observational study included 431 patients who were diagnosed with neovascular AMD. Patients were divided into three groups: type 1 or 2 neovascularization group ( n = 167), type 3 neovascularization group ( n = 50), and polypoidal choroidal vasculopathy (PCV) group ( n = 214). The number of hospital visits per year and the number of anti-vascular endothelial growth factor (VEGF) injections per year were compared among these groups. Furthermore, the incidence of bilateral involvement during the follow-up period was compared among the groups. Results The mean follow-up period was 50.6 ± 11.3 months. The number of hospital visits per year was significantly higher in the type 1 or 2 neovascularization group (mean: 6.1 ± 1.5) and type 3 neovascularization (6.6 ± 1.6) than in the PCV group (6.0 ± 1.5) ( P < 0.001). The number of anti-VEGF injections per year was significantly higher in type 3 neovascularization group (3.1 ± 1.7) than in the type 1 or 2 neovascularization group (2.3 ± 1.5) or the PCV group (2.3 ± 1.2) ( P = 0.042). There was a significant difference in the incidence of bilateral involvement among patients in type 1 or 2 neovascularization group (20.4%), type 3 neovascularization group (46.0%), and the PCV group (15.4%) ( P < 0.001). Conclusions The high frequency of hospital visits and that of anti-VEGF injections in patients with type 3 neovascularization suggests high treatment burden in these patients. The high incidence of bilateral involvement could be one of the primary reasons for high treatment burden in patients with type 3 neovascularization.
