Summary

The purpose of this study is to understand the role of nutrition and its effects on the eye and other tissues. The investigators propose to study this by validating and correlating various non-invasive measurement methods of carotenoid concentrations in the human eye and skin tissue.

A secondary objective is to correlate blood levels of carotenoids on a sub-set of participants.

Conditions

  • Macular Pigmentation
  • Skin Pigment

Interventions

OTHER

Carotenoid measurements

Carotenoid measurements of the eye (macula) are obtained through non-invasive ophthalmic photographs using the Heidelberg Spectralis imaging system. Carotenoid measurements of the skin are measured by a laboratory instrument that uses a painless blue laser light for exposure of the skin and a photodetector for scattered light. Carotenoid measurements in the blood are obtained through routine venipuncture.
