Abstract

PURPOSE To compare the 12-month real-world visual and disease activity outcomes of eyes with polypoidal choroidal vasculopathy (PCV) treated with a combination of photodynamic therapy (PDT) and anti-vascular endothelial growth factor (VEGF) injections (combination group) versus those eyes treated with anti-VEGF monotherapy alone with rescue PDT being used as required (monotherapy group). DESIGN Database comparative observational study. PARTICIPANTS Eyes with PCV as graded in the Fight Retinal Blindness! database from Australia, New Zealand, Singapore, and Switzerland. METHODS Clinical information from a multisite, international registry of neovascular age-related macular degeneration was analyzed with an intention-to-treat approach. MAIN OUTCOME MEASURES Primary outcome measure was the change in visual acuity in logMAR letters over 12 months between the two groups analyzed with intention-to-treat approach. RESULTS Forty-one and 152 eyes received combination therapy and anti-VEGF monotherapy, respectively. All anti-VEGF agents were pooled, and bevacizumab represented 66.1% of injections administered. The adjusted mean change in visual acuity between the combination group and monotherapy group at 12 months was +16.9 letters (95% confidence interval [CI], 10.6-23.3 letters) and +8.2 letters (95% CI, 5.2-11.3 letters), respectively (P = 0.02). Proportion of inactive lesions and mean time to inactivity was 85.3% and 80.7 days (95% CI, 62.8-98.5 days), respectively, in the combination group compared with 76.8% and 150.4 days (95% CI, 132.8-168.0 days), respectively, in the monotherapy group (P = 0.01). The mean number of injections of anti-VEGF agent between the combination and monotherapy groups was 4.3 injections (95% CI, 3.6-5.2 injections) and 6.4 injections (95% CI, 5.9-6.9 injections), respectively (P = 0.01). CONCLUSIONS The real-world outcomes for treatment of PCV showed larger gains in vision, higher proportion of inactive lesions, quicker time to inactivity, and fewer injections administered in the combination group compared with the monotherapy group. These findings are consistent with current evidence reporting the advantages of combination therapy for PCV.
