This is a retrospective cohort study comprised of 70 eyes being treated for polypoidal choroidal vasculopathy with combined photodynamic therapy and intravitreal bevacizumab injections. Patients were genotyped for the LOC387715 (rs10490924) and the HTRA1 gene polymorphism (rs11200638).
This study is to investigate whether there is an association of the LOC387715/HTRA1 variants with response to treatment with combined photodynamic therapy and intravitreal bevacizumab for patients with polypoidal choroidal vasculopathy.
