Real world experience of the treatment outcome between photodynamic therapy combined with ranibizumab and aflibercept monotherapy in polypoidal choroidal vasculopathy.

To provide real-world experiences of treating polypoidal choroidal vasculopathy (PCV) patients with photodynamic therapy (PDT) plus intravitreal injection of ranibizumab or intravitreal injection of aflibercept alone. Retrospective chart review of patients with PCV in a single tertiary referral center in Taiwan. Chart review of PCV patients treated with PDT and injection of ranibizumab or injection of aflibercept. A total of 101 eyes of 101 patients (38 females and 63 males) were reviewed. Of those, 48 and 53 eyes received primary/adjunctive PDT along with injections of ranibizumab or intravitreal injections of aflibercept only, respectively. Initial visual acuity (VA) and central subfield choroidal thickness were similar between the two groups (p > 0.05). In addition, changes in VA at 3, 6, and 12 months post treatment were similar. The central retinal thickness decreased with either treatment (p < 0.01); however, this change did not translate into VA performance (p > 0.05). In the subgroup analysis of pachychoroid and non-pachychoroid patients, better initial VA and post-treatment VA at 3 months and 6 months was noted in the latter group of patients treated with anti-vascular endothelial growth factor monotherapy (p < 0.05). Aflibercept monotherapy is comparable with PDT plus ranibizumab in PCV patients with PCV (pachychoroid and non-pachychoroid patients). In addition, better prognosis regarding VA was observed in non-pachychoroid patients treated with aflibercept monotherapy.
