- Abstract: PURPOSE: To evaluate the long-term outcomes of anti-vascular endothelial growth factor (VEGF) therapy for polypoidal choroidal vasculopathy (PCV) with feeder vessels and to investigate fellow-eye findings. METHODS: This retrospective observational study included 14 eyes with treatment-naïve PCV accompanied by feeder vessels that were treated with anti-VEGF monotherapy. The best-corrected visual acuity (BCVA) at baseline was compared with that at the last follow-up. The fellow-eye indocyanine green angiography findings were also analyzed. RESULTS: The mean follow-up period was 28.1 ± 19.2 months (range, 12 to 60 months). During the follow-up period, 5.9 ± 2.5 anti-VEGF injections were administered. The logarithm of the minimal angle of resolution (logMAR) BCVAs at the time of diagnosis, at 3 months, and at the last follow-up were 0.81 ± 0.49, 0.55 ± 0.44, and 0.71 ± 0.54, respectively. Although the BCVA at the last follow-up was not different from the baseline value (p=0.809), an improvement of ≥0.2 logMAR BCVA was observed in seven eyes (50.0%). In 11 eyes that underwent bilateral indocyanine green angiography at diagnosis, PCV, branching vascular networks, and late geographic hyperfluorescence were noted in two (18.2%), five (45.4%), and three (27.3%) fellow eyes, respectively. During the follow-up period, the development of polypoidal lesions in the fellow eye was observed in three patients. CONCLUSIONS: In this study, long-term improvement in BCVA was noted in 50% of the included patients who received anti-VEGF monotherapy. A relatively high incidence of pathological findings in the fellow eye and bilateral involvement suggest the need for bilateral examinations.
