Comparison of clinical features and 3-month treatment response among three different choroidal thickness groups in polypoidal choroidal vasculopathy.

ABSTRACT: Eyes with polypoidal choroidal vasculopathy (PCV) were recently reported to have various choroidal thickness, and choroidal thickness might be associated with visual outcome in the treatment of many retinal disorders. The range of subfoveal choroidal thickness (SFCT), clinical features, and 3-month treatment response among three groups having different range of SFCT were investigated in PCV eyes. In 78 treatment-naïve eyes with PCV, SFCT was measured using optical coherence tomography. Eyes were classified into thin, medium, and thick groups, using mean and one standard deviation of SFCT. Clinical features and imaging findings were compared among the three groups. Some eyes were treated with three consecutive monthly injection of anti-vascular endothelial growth factor (VEGF) as an initial treatment. They were also classified into three thickness groups, and the short-term post-treatment improvement in visual acuity and central retinal thickness were compared among groups. The mean SFCT was 271.9 ± 135.6 ?m. Twelve, 53, and 13 eyes were classified into thin (<136.3 ?m), medium (136.3-407.5 ?m), and thick (>407.5 ?m) groups, respectively. The thin group showed older age, lower visual acuity, and a higher prevalence of fundus tessellation than the other two groups (P <0.05). In multiple linear regression analyses, baseline BCVA was correlated with baseline SFCT. Forty-six eyes completed three consecutive anti-VEGF treatments. The thin group showed no visual improvement after treatment (P = 0.141), unlike the other two groups showing visual improvement (P<0.05). Eyes with PCV have a broad range of SFCT, and PCV eyes with a thin choroid manifest worse visual function than eyes with a medium or thick choroid.

Project description:PurposeTo evaluate the status and evolution of polypoidal lesions during the course of treatment of patients with symptomatic macular polypoidal choroidal vasculopathy (PCV).DesignComparative cohort study of randomly selected patients from a multicenter, randomized controlled clinical trial.ParticipantsThirty 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).MethodsAll 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.Main outcome measuresComplete polypoidal lesion regression over time.ResultsComplete 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).ConclusionsCombination 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.
