Purpose
This study is to investigate whether there is an association of the LOC387715/HTRA1 and vascular endothelial growth factor polymorphism with response to treatment with intravitreal ranibizumab injections for patients with polypoidal choroidal vasculopathy.

Primary Outcome Measures:
- Best-corrected visual acuity [ Time Frame: up to 12 months ]Best-corrected visual acuity (BCVA) using the Snellen chart was evaluated including BCVA before treatment and BCVA up to 12 months.
Secondary Outcome Measures:
- Angiographic characteristics [ Time Frame: up to 12 months ]Fluorescein angiography (FA) and ICGA (HRA; Heidelberg Engineering, Dossenheim, Germany)were evaluated. Greatest linear dimension (GLD) was determined based on both FA and ICGA.
Biospecimen Retention: Samples With DNA
Genomic DNA was extracted from peripheral blood with the Qiagen QIAamp Blood Kit (Qiagen, Valencia, CA).

polypoidal choroidal vasculopathy
patients who were treated for polypoidal choroidal vasculopathy with intravitreal injections of 0.5 mg of ranibizumab monthly for 3 months

Detailed Description:
This is a retrospective comparative case series comprised of 70 patients being treated for polypoidal choroidal vasculopathy with intravitreal ranibizumab injections and 112 control subjects. Patients were genotyped for the LOC387715 (rs10490924), HTRA1 gene (rs11200638), and VEGF (rs3025039 and rs833069)polymorphism using Real-Time polymerase chain reaction.
