Purpose: The aim of this study was to investigate whether polymorphisms in the vascular endothelial growth factor A gene (VEGF-A) are associated with polypoidal choroidal vasculopathy (PCV) in a Korean population and whether they are associated with PCV phenotypes. Methods: This was a case-control study comprising 111 patients with PCV and 123 control participants. The PCV and control groups were genotyped for five polymorphisms in VEGF-A. Clinical characteristics were evaluated, including best-corrected visual acuity, fundus findings, and angiography findings at the first visit. Main outcome measures were the genotypes of variants and association with phenotypes. Results: Only rs833069 in VEGF-A generated significant allelic associations with PCV (P = 2.24 9 10-5). As compared with the AA group, the GG genotype group in rs833069 had a 6.25-fold increased risk of PCV [P = 7.45 × 10 -5, 95% confidence interval (CI) 2.52-15.46] and the AG group had a 1.82-fold increased risk (P = 0.029, 95% CI 1.03-3.24). The haplotype CCGC in VEGFA showed an association with PCV (P = 2.90 9 10-5). However, the phenotypic characteristics of PCV did not show an association with the rs833069 genotypes. Conclusions: The rs833069 polymorphism in VEGFA was significantly associated with the risk of PCV in a Korean population. © Japanese Ophthalmological Society 2012.
