Purpose
To compare the one-year visual and anatomic outcomes of an as-needed regimen of brolucizumab and aflibercept for polypoidal choroidal vasculopathy (PCV).
Study design
A retrospective comparative study.
Methods
A retrospective medical chart review was performed for consecutive 56 eyes from 56 patients with PCV initially treated with thee monthly intravitreal aflibercept (n = 33, 2.0 mg/0.05 ml) or brolucizumab (n = 23, 6.0 mg/0.05 ml) followed by as-needed administration, followed up for at least 12 months. All patients were followed up monthly, and fluorescein and indocyanine green angiography (ICGA) were performed at baseline, 3-month, and 12-month visits.
Results
At the 12-month visit, best-corrected visual acuity significantly improved from 0.30 ± 0.31 to 0.21 ± 0.29 (p = 0.042) in the brolucizumab-treated group and from 0.24 ± 0.25 to 0.14 ± 0.25 (p = 7.7×10−3) in the aflibercept-treated group, suggesting comparable visual improvement in both groups. Central retinal thickness and subfoveal choroidal thickness decreased by 38.4% and 14.2%, respectively, in the brolucizumab-treated group and by 34.8% and 13.9%, respectively, in the aflibercept-treated group at the 12-month visit. The mean number of additional injections was significantly higher in the aflibercept-treated group (2.9 ± 2.7) than in the brolucizumab-treated group (1.3 ± 1.2, p = 0.045). The complete resolution of polypoidal lesions on ICGA was higher in the brolucizumab-treated group than in the aflibercept-treated group (3-month visit: 56.5% vs 30.3%, 12-month visit: 56.5% vs 30.3%).
Conclusions
In treatment-naïve eyes with PCV, the as-needed administration regimen of brolucizumab was comparable to aflibercept in terms of visual and anatomical outcomes, with fewer additional injections during the 12-month follow-up.
