Background  To evaluate 5-year outcomes of anti-vascular endothelial growth factor (VEGF) monotherapy and combination therapy of anti-VEGF agents and photodynamic therapy (PDT) for polypoidal choroidal vasculopathy (PCV) in a real-world Chinese population.    Methods  Retrospective study. Fifty-three eyes of 46 patients with subtype 1 and 2 PCV followed up for at least 60 months were grouped into three regimens: anti-VEGF monotherapy, PDT combining with anti-VEGF therapy initially, and PDT combining with deferred anti-VEGF therapy. Main outcome measure was best-corrected visual acuity (BCVA) using logarithm of minimal angle of resolution (logMAR).    Results  The mean BCVA of eyes with subtype 1 PCV ( n  = 28) deteriorated from 0.69 logMAR at baseline to 1.25 logMAR at months 60 ( P  = 0.001), while the mean BCVA of eyes with subtype 2 PCV ( n  = 25) sustained stable from 0.62 logMAR at baseline to 0.57 at months 60 ( P  = 0.654). No significant differences of visual outcomes were found between the 3 treatment regimens for subtype 1 PCV. Anti-VEGF monotherapy and initial combination treatment had better visual outcomes in eyes with subtype 2 PCV than deferred combination group during part of follow-up significantly. Initial combination group needed a less number of PDT than deferred combination group ( P  < 0.001).    Conclusions  Compared with subtype 1 PCV, subtype 2 PCV has a more favorable visual outcome in real world. All the regimens presented unfavorable visual outcomes for subtype 1 PCV. Anti-VEGF monotherapy and initial combination therapy should be superior to deferred combination therapy in the long-term management of subtype 2 PCV. Prospective randomized studies of larger size are needed to determine the long-term efficacy and safety of various treatment for PCV in real world.
