We compared the short-term outcomes between 3-monthly aflibercept and brolucizumab injections for treatment-naïve polypoidal choroidal vasculopathy (PCV). A total of 52 eyes were included. Patients received 3 monthly intravitreal aflibercept (n = 38) or intravitreal brolucizumab (n = 14). Indocyanine green angiography (ICGA) was performed at baseline and at the 3-month visit. Selection of anti-VEGF agents depended on time. In the brolucizumab-treated group, best-corrected visual acuity (BCVA) improved from 0.27 ± 0.34 (log MAR unit) at baseline to 0.20 ± 0.24 at 3-month visit, which is comparable with the aflibercept-treated group (p = 0.87), after adjustment of confounding factors. Central retinal thickness significantly decreased by 43%−44% in both groups. Subfoveal choroidal thickness also significantly decreased by 20.5% during this interval in the brolucizumab-treated group, which was greater than the aflibercept-treated group. The complete resolution rate of polypoidal lesions on ICGA was significantly higher (p = 0.043) in the brolucizumab-treated group (78.6%) than in the aflibercept-treated group (42.1%). Intraocular inflammation was observed in 14.3% (2/14) in the brolucizumab-treated group only. In short-term follow-up, intravitreal injection of 3-monthly brolucizumab was comparable with aflibercept in terms of BCVA and morphological improvement along with higher resolution of polypoidal lesion(s) on ICGA.

We investigated the clinical and genetic characteristics of patients with unilateral exudative age-related macular degeneration (AMD), including typical AMD, polypoidal choroidal vasculopathy, and retinal angiomatous proliferation, in whom pachydrusen was seen. Patients with unilateral exudative AMD with at least a 12-month follow-up period were included. According to the fellow eye condition, 327 consecutive patients were classified into 4 groups: Group 0: no drusen (42.8%), Group 1: pachydrusen (12.2%), Group 2: soft drusen (30.3%), Group 3: pseudodrusen with or without soft drusen (14.7%). Development of exudative AMD in the fellow eye was retrospectively studied for a 60-month period and this inter-group comparisons were performed. Genotyping was performed for ARMS2 A69S and CFH I62V. The thickness of the choroid in the fellow eyes increased significantly in Group 1 than in other groups (all P < 1.0 × 10 −7 ). The development of exudative AMD in the fellow eye was significantly less frequent in Group 1 than in Groups 2 or 3 (P = 0.022 and 0.0015, respectively). Risk allele frequency of ARMS2 A69S was significantly lower in Group 1 than in Group 2 and 3 (all P < 1.0 × 10 −4 ). Patients with pachydrusen have genetic and clinical characteristics distinct from those of soft drusen and pseudodrusen.

Photodynamic therapy (PDT) combined with intravitreal anti-vascular endothelial growth factor (VEGF) agents is currently the first-line treatment for polypoidal choroidal vasculopathy (PCV), along with anti-VEGF monotherapy. In this study, 100 eyes with treatment-naïve PCV were initially treated with PDT combined with intravitreal ranibizumab (IVR; n = 57) or aflibercept (IVA; n = 43). We compared two-year outcomes between these two groups and investigated factors associated with visual improvement and retreatment over 24 months. Best-corrected visual acuity (BCVA) was significantly improved in both groups (P < 0.001) at 24 months. Multiple regression analysis revealed that visual improvement at 24 months was associated with female (P = 0.030), worse baseline BCVA (P = 3.0 × 10−6), smaller greatest linear dimension (GLD; P = 2.0 × 10−4), and treatment with IVA rather than IVR (P = 0.016). Multiple logistic regression analysis revealed that absence of retreatment was associated with younger age (P = 2.2 × 10−4), female (P = 1.2 × 10−3), and the non-risk variants of ARMS2 A69S (P = 6.0 × 10−4). Although there were no significant differences in the retreatment rate between the two groups, PDT/IVA may be superior to PDT/IVR in terms of visual improvement at 24 months.

We report 5-year visual and anatomical outcomes after combination therapy of photodynamic therapy (PDT) and intravitreal injection of ranibizumab or aflibercept for polypoidal choroidal vasculopathy (PCV) and predictive factors for visual outcomes at 5-year and time to recurrence. Medical charts were retrospectively reviewed for 43 consecutive eyes with PCV treated with combination therapy of PDT and intravitreal injection of ranibizumab(n = 13) or aflibercept(n = 30) and completed 5-year follow-up. The variants of ARMS2 A69S and CFH I62V were genotyped using TaqMan assay. Best corrected visual acuity (BCVA) significantly improved at 5-year (P = 0.01) with 20% reduction of subfoveal choroidal thickness irrespective of presence or absence of recurrence. Visual improvement was associated with baseline shorter greatest linear dimension (GLD) (P = 1.0×10 −4). Mean time to recurrence was 28.6±23.1 months (95% CI: 21.5-35.7, Median:18.0) and time to recurrence was associated with G allele (protective allele) of ARMS2 A69S and GLD (P = 4.0×10 −4 and 1.0×10 −2 , respectively). Multiple regression analysis revealed that time to recurrence extended by 15.5 months when the G allele of ARMS2 A69S increased by one allele (TT: 15.7±17.0, TG: 30.8±23.5, GG: 41.1±22.6 months). The combination therapy resulted in a favorable visual outcome for PCV during 5-year follow-up.
