This study is to investigate whether variants in the LOC387715 locus and the HtrA serine peptidase 1 (HTRA1) gene within the 10q26 locus are associated with polypoidal choroidal vasculopathy and whether they are associated with clinical patterns including angiographic phenotype in a Korean population.

This is a cross-sectional case-control study. One hundred Korean patients with polypoidal choroidal vasculopathy and 100 control subjects were genotyped for the LOC387715 (rs10490924) and the HTRA1 gene polymorphism (rs11200638)

Polypoidal choroidal vasculopathy group

Inclusion Criteria:

• patients older than 60 years of age at onset
• polyp-like terminal aneurysmal dilations with or without branching vascular networks in indocyanine green angiography and subretinal reddish-orange protrusions corresponding to polyp-like lesions

Exclusion Criteria:

• eyes with pathologic myopia, angioid streaks, central serous chorioretinopathy, and other retinal or choroidal diseases

Control group

Inclusion Criteria:

• individuals without retinal diseases and without any signs of polypoidal choroidal vasculopathy or age-related macular degeneration on the bases of comprehensive ophthalmic examination results
