    Abstract:
    PURPOSE: To survey the prevalence and clinical and genetic characteristics of pachydrusen in eyes with central serous chorioretinopathy (CSC) and those of Japanese individuals in the general population. DESIGN: Prospective, observational cohort study. PARTICIPANTS: One thousand thirty-seven Japanese patients were included in this study. Three hundred seven patients (614 eyes) had treatment-naïve CSC without choroidal neovascularization in either eye, whereas 730 individuals (1640 eyes) were Japanese individuals from the general population without explicit ocular diseases. METHODS: Pachydrusen were detected using color fundus photography, and subfoveal choroidal thickness was measured using OCT. Genotypic distributions of 3 single nucleotide polymorphisms, ARMS2 A69S, CFH I62V, and CFH Y402H, were evaluated. MAIN OUTCOME MEASURES: Prevalence of pachydrusen and association with choroidal thickness. RESULTS: The prevalence of pachydrusen was significantly higher among CSC patients than among the general population group (40.1% vs. 15.6%; P < 0.001). Individuals with pachydrusen in either group were significantly older than those without pachydrusen (CSC patients: 62.1 years vs. 48.8 years [P < 0.001]; general individuals: 70.3 years vs. 51.9 years [P < 0.001]). No significant difference was found in subfoveal choroidal thickness between those with and without pachydrusen (CSC patients: 370 μm vs. 375 μm; [P = 0.574]; general population: 297 μm vs. 303 μm [P = 0.521]). However, after adjusting for age, gender, and refractive error, subfoveal choroidal thickness was notably thicker in individuals with pachydrusen than that in individuals without pachydrusen in both groups (P = 0.003 and P = 0.013, respectively). No significant difference was found in genotype distributions between CSC patients with pachydrusen and those without it; whereas, the T allele frequency of ARMS2 A69S was higher in general population individuals with pachydrusen than that in general population individuals without pachydrusen (42.2% vs. 33.9%; P < 0.001; OR, 1.86, adjusted for age, gender, and choroidal thickness). CONCLUSIONS: Pachydrusen was observed more frequently in CSC patients compared with individuals from the general population. In both groups, pachydrusen was associated with a thicker choroid, suggesting that pachydrusen should be considered as a significant sign of pachychoroid.
