PIIR Study: Comparison of Genetic Tests for Age-Related Macular Degeneration
Study Details
Study Description
Brief Summary
This study is being conducted to compare two different genetic tests developed to determine an individuals risk of developing serious vision threatening complications from age-related macular degeneration (ARMD).

Detailed Description
There are currently two different genetic tests that have been developed for this purpose. They both look at specific DNA components to determine the risk. Participants in the study will be over the age of 60 years and caucasian as this is the population of people in which these tests have been validated. Each participant will have the study explained to them and then will be asked to sign the informed consent document if they agree to participate. They will have a dilated exam of their eyes along with photographs taken of the retina. If their doctor sees that it is necessary they will also have a special scan or a special angiogram of their eyes to look at their retina in more detail. For the genetic testing a member of the research team will use two swabs from each of the genetic companies to gently scrap some cells from the inside of the cheek. These cells will be sent to each respective lab for analysis.

---|---|
ARMD Free Patient free of ARMD on clinical examination |

ARMD Positive Patients with evidence of ARMD on clinical examination |
Outcome Measures
Primary Outcome Measures
- Risk score from RetnaGene [Day 1]
Risk score assigned after genetic analysis of a buccal swab by the RetnaGene (Sequenom) genetic test.
- Risk score from Macula Risk [Day 1]
Risk score assigned after genetic analysis of a buccal swab by the Macula Risk genetic test.
