The Moran AMD Genetic Testing Assessment Study (MAGENTA)
A Phase 2 Study of the Value of Pre-symptomatic Genetic Risk Assessment for Age-Related Macular Degeneration
The goals of this study are:
To assess the impact of genetic testing for Age-related Macular Degeneration (AMD) on lifestyle behaviors as measured by systemic and ocular carotenoid status.

Eligibility Criteria
Eligibility Criteria
Ages Eligible for Study
Accepts Healthy Volunteers
Description
Inclusion Criteria:
- Participants must be between 18 and 64 years of age.
- They must also be Caucasian as this genetic test is only validated in Caucasians.
- They can have a positive family history of AMD but this is not necessary.
Exclusion Criteria:
- Personal history of AMD
- Non Caucasian
- Employee of the Moran or other eye care practice (likely to have more knowledge about AMD than a layperson)
- Personal history of prior genetic testing for AMD risk
- Anticipated cataract surgery in the upcoming year (can affect Macular Pigment measurement)
- Major psychiatric disorder

Measure Description |
Time Frame |
|---|---|---|
|
Change in Skin Carotenoid Status in Response to Genetic Risk Disclosure as Measured by Reflectance Spectroscopy
Time Frame: Baseline and Month 12
|
Reflectance Spectroscopy (RS) is measured by Reflection Units.
Possible scores range from 0 (no carotenoids detected) to greater than 500.
Change = (Month 12 Score - Baseline Score).

|
Change in Skin Carotenoid Status in Response to Genetic Risk Disclosure as Measured by Resonance Raman Spectroscopy
Time Frame: Baseline and Month 12
|
Resonance Raman Spectroscopy (RSS) is measured in Resonance Raman Units (RRU).
Possible scores range from 0 (no carotenoids detected) to greater than 100,000.
Change = (Month 12 Score - Baseline Score).

Measure Description |
Time Frame |
|---|---|---|
|
Change in Ocular Carotenoid Status in Response to Genetic Risk Disclosure as Measured by Macular Pigment Optical Volume
Time Frame: Baseline and Month 12
|
Macular Pigment Optical Volume (MPOV) is a unitless measure of the amount of carotenoids present in the macula.
Possible scores range from 0 (no carotenoids detected) to greater than 50,000.
Change = (Month 12 Score - Baseline Score).
|
Baseline and Month 12
|
|
Change in Serum Carotenoid Status in Response to Genetic Risk Disclosure
Time Frame: Baseline and Month 12
|
Serum carotenoid levels are measured in nanograms per milliliter (ng/mL).
Possible scores range from 0 (no carotenoids detected) to greater than 1,000.
Change = (Month 12 Score - Baseline Score).
