Further study details as provided by Kocatepe University:

Primary Outcome Measures:
  • rate of homozygous, heterozygous or wild type genotype and allels [ Time Frame: at the end of third years ]
    Gene polymorphisms of 8 region with identification of homozygous, heterozygote and wild type genotyping and alleles

Secondary Outcome Measures:
  • Odds ratios for each genotyping in healthy elderly controls and patients with age related macular degeneration [ Time Frame: at the end of third years ]

Other Outcome Measures:
  • Odds ratios for various combinations of gene regions between healthy elderly control and patients with age related macular degeneration [ Time Frame: at the end of third years ]

Biospecimen Retention:   Samples With DNA
Whole blood

Estimated Enrollment: 5000
Study Start Date: November 2012
