{Abstract}: UNASSIGNED: To evaluate the status and evolution of polypoidal lesions during the course of treatment of patients with symptomatic macular polypoidal choroidal vasculopathy (PCV).
UNASSIGNED: Comparative cohort study of randomly selected patients from a multicenter, randomized controlled clinical trial.
UNASSIGNED: Thirty randomly selected patients from the EVEREST II study who were treated with combination ranibizumab and verteporfin photodynamic therapy (n = 15) or ranibizumab monotherapy (n = 15).
UNASSIGNED: All patients were randomized at baseline and treated with a standardized treatment protocol. Indocyanine green angiography (ICGA) images were graded at the central reading center at baseline and months 3, 6, 12, and 24. Polypoidal lesions present at baseline were overlaid on ICGA images at subsequent visits to determine if these remained perfused or had regressed completely. New polypoidal lesions occurring at subsequent visits were similarly tracked to detail the evolution of each polypoidal lesion.
UNASSIGNED: Complete polypoidal lesion regression over time.
UNASSIGNED: Complete polypoidal lesion regression was higher in the combination therapy group compared with the monotherapy group at all visits (month 12, 12 of 15 patients [80%] vs. 5 of 14 patients [35.7%]; P = 0.016). Persistence of baseline polypoidal lesions was lower in the combination therapy group: 1 of 15 patients (6.7%) versus 7 of 14 patients (50%) in the monotherapy group at month 12. Recurrences of polypoidal lesions that had regressed completely at an earlier time point were uncommon: 0% in the combination therapy group and 1 patient each at months 6 and 12 in the monotherapy group. Fewer new polypoidal lesions (arising after the baseline visit) were found in the combination therapy group at all visits (combination therapy: 2 of 15 [13.3%] vs. monotherapy: 4 of 14 eyes [28.6%] at month 12). Total polypoidal lesion area was significantly smaller in the combination therapy group compared with the monotherapy group throughout the study (0.013 mm2 vs. 0.110 mm2; P < 0.01 at month 12).
UNASSIGNED: Combination therapy was associated with higher rates of complete polypoidal lesion regression and fewer persistent polypoidal lesions compared with monotherapy. Closed polypoidal lesions rarely reopened, regardless of the treatment.
