摘要

Purpose

To evaluate long-term outcomes for polypoidal choroidal vasculopathy (PCV) in Japanese patients in the EVEREST II study.

Study design

A multicenter, cross-sectional study of the long-term outcomes of a cohort of patients originally treated with ranibizumab alone (monotherapy group) or in combination with photodynamic therapy PDT (combination group) in the EVEREST II study (ClinicalTrials.gov identifier, NCT 01846273).

Methods

Ninety participants from the six-year EVEREST II follow-up: 20 Japanese and 70 non-Japanese were included. Long-term changes in best-corrected visual acuity (BCVA) and central subfield thickness (CST) were reported in the Japanese compared to non-Japanese participants. Number of injections, types of anti-vascular endothelial growth factor (VEGF) agents used, and cases with equal visits and injections, indicating fixed dosing or treat-and-extend (TAE) administration were investigated. Outcomes were also compared between those who had verteporfin PDT during the six-year period (n=14) and those who did not (n=6).

Results

The Japanese and non-Japanese participants had similar baseline characteristics. The mean age for Japanese participants was 76±4.47 years, with 25% being women. BCVA improved from baseline to year 2 in both groups (P < 0.05). At six years, BCVA was maintained in the Japanese (67.2 ETDRS letters) but decreased in the non-Japanese participants (from 68.8 to 53.5 letters). The Japanese participants received more injections than the non-Japanese (12.5 vs. 7.57, P=0.017). Aflibercept was the most frequently used anti-VEGF agent, and the number of fixed dosing or TAE administration was higher in the Japanese participants. No significant differences were found in functional and anatomical outcomes between those who received PDT and those who did not (all P > 0.05). However, non-PDT participants had numerically worse BCVA at the final visit.

Conclusions

This study highlights positive long-term outcomes for Japanese PCV patients and underscores the need for further research to validate these findings in broader patient populations.
