Age-Related Macular Degeneration
Conditions
Brief summary
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.
Detailed description
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).

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Best-corrected visual acuity | up to 12 months | Best-corrected visual acuity (BCVA) using the Snellen chart was evaluated including BCVA up to 12 months |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Angiographic characteristics | up to 12 months | Fluorescein angiography (FA) and ICGA (HRA; Heidelberg Engineering, Dossenheim, Germany) was evaluated. Greatest linear dimension (GLD) was determined based on both FA and ICGA. |
