Macular Pigment Density Supplementation Clinical Trial

Study Title

Comparison of Macular Pigment Optical Density before and after Oral Carotenoid Supplementation in Type 2 Diabetic Patients Using Two Wavelength Autofluorescence Imaging

Enrollment Status

This study is currently recruiting participants.


The purpose of this study is to determine whether retinal macular pigment density can be increased via dietary supplementation with lutein and/ or zeaxanthin in diabetic patients without retinopathy or with mild diabetic retinopathy. Second, to measure and correlate the macular pigment levels and glycemic control with the Macular Pigment Density Reflectometer, retinal structure (SLO/OCT) and retinal function blood flow (RFI)


Ages Eligible for Study: 21 years old and older

Genders Eligible for Study: Both

Inclusion Criteria

  • Subject has the diagnosis of Type 2 Diabetes.
  • Aged 21 or older.
  • Willing to take nutritional supplements of Lutein, and/ or Zeaxanthin.
