Purpose To evaluate the long-term visual outcome after combination therapy of photodynamic therapy (PDT) with intravitreal bevacizumab injections for polypoidal choroidal vasculopathy (PCV). Design Retrospective observational study. Methods The medical records of 34 eyes (34 patients) with naïve PCV who were treated with combination therapy were analyzed. All patients completed at least 3 years of follow-up. All clinical data, including age, best-corrected visual acuity (BCVA, logarithm of the minimal angle of resolution [logMAR]), imaging data of fluorescein angiography, indocyanine green angiography, and optical coherence tomography, were investigated. Results During a mean follow-up period of 46.8 ± 5.2 months, a mean of 1.4 ± 0.71 times of PDT and 9.2 ± 6.6 intravitreal bevacizumab injections were performed. During follow-up, 21 eyes (61.8%) showed at least 1 recurrence. Mean BCVA was 0.59 ± 0.35 logMAR (20/77 Snellen equivalent) at baseline and 0.39 ± 0.34 logMAR (20/49 Snellen equivalent) at 3 years (P =.004). At 3 years, 14 patients (41.2%) gained 0.3 logMAR or more BCVA and 4 patients (11.8%) lost 0.3 logMAR or more BCVA than baseline. Baseline polyp size (β =.551; P =.005) and location of polyps (β = -.400; P =.033) were significantly correlated with long-term visual outcome after combination therapy for PCV. Conclusions Combination therapy of PDT with intravitreal bevacizumab injections showed favorable visual outcomes, and significant visual improvement was maintained in PCV patients. A total of 88.2% of patients avoided visual loss at 3 years after treatments. Largest polyp size at baseline and location of polypoidal lesions were prognostic factors for long-term visual outcomes in these patients.
