Outcome Measures

Primary Outcomes (2)

  • Change in Skin Carotenoid Status in Response to Genetic Risk Disclosure as Measured by Reflectance Spectroscopy

    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).

    Baseline and Month 12

  • Change in Skin Carotenoid Status in Response to Genetic Risk Disclosure as Measured by Resonance Raman Spectroscopy

    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).

    Baseline and Month 12

Secondary Outcomes (2)

  • Change in Ocular Carotenoid Status in Response to Genetic Risk Disclosure as Measured by Macular Pigment Optical Volume

    Baseline and Month 12

  • Change in Serum Carotenoid Status in Response to Genetic Risk Disclosure

    Baseline and Month 12

Eligibility Criteria

Age18 Years - 64 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64)

You may qualify if:

  • 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.

You may not qualify if:

  • 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

Limitations and Caveats

Our study population was mainly Caucasian because the genetic testing had been validated in this population. Due to logistical constraints, we could not undertake expanded measures of lifestyle modification and coaching, potential active nutritional interventions, or follow-up with individuals in the deferred disclosure group to determine any psychological impact.
