Further study details as provided by Dong Ho Park, Kyungpook National University:

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 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) was 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. The two SNPs (rs10490924 in the LOC387715 locus and rs11200638 in HTRA1 gene) were analyzed by LC480 Real time PCR (Roche, Basel, Switzerland) at D&P Biotech (Daegu, Korea).

polypoidal choroidal vasculopathy
patients who were treated for polypoidal choroidal vasculopathy with combined photodynamic therapy and intravitreal bevacizumab injections

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).

Ages Eligible for Study:   60 Years to 80 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
The authors did a retrospective chart review of 70 patients with PCV who were treated at the Department of Ophthalmology, Kyungpook National University Hospital in Daegu, Korea.

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 (ICGA) and subretinal reddish-orange protrusions corresponding to polyp-like lesions
  • patients who had combined photodynamic therapy and intravitreal bevacizumab injections, and followed up for more than 12 months after the first treatment

Exclusion Criteria:

  • patients with retinal or choroidal diseases including pathologic myopia, angioid streaks, idiopathic choroidal neovascularization (CNV), presumed ocular histoplasmosis, and other secondary CNV
  • patients who refused genotypic analyses
