Change in Skin Carotenoid Status in Response to Genetic Risk Disclosure as Measured by Reflectance SpectroscopyPrimary· 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 SpectroscopyPrimary· 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).

Change in Ocular Carotenoid Status in Response to Genetic Risk Disclosure as Measured by Macular Pigment Optical VolumeSecondary· 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).

Change in Serum Carotenoid Status in Response to Genetic Risk DisclosureSecondary· 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).

Time frame: 12 months.
Reporting threshold: 0%.
Adverse-event reports describe events observed during the trial — not all are caused by the drug.
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.
