NCT00006202

Brief Summary

This study will examine whether taking the vitamin lutein changes lutein blood levels. Lutein, vitamin C, vitamin E and beta-carotene may be useful in treating the eye disease age-related macular degeneration, but more information is needed to support this. Age-related macular degeneration can significantly impair the ability to read, drive, and carry out daily activities. It is the most common cause of vision loss in people over age 60. Lutein a carotenoid that occurs naturally in the retina (the back part of the eye), especially the macula-the part of the retina that is important for fine, detailed vision. Men and women 60 years of age and older, with or without age-related macular degeneration, may be eligible for this study. Candidates will undergo the following tests:

  1. 1.Medical history and physical examination.
  2. 2.Eye examination-Includes evaluation of visual acuity, measurement of eye pressure, examination of the lens, retina, pupils and eye movements, and photographs of the eye.
  3. 3.Visual field study-Examines the ability to see objects in the periphery. The subject looks at a target on a screen and indicates when lights that appear in other places on the screen are visible.
  4. 4.Flicker photometry-The subject looks at a flashing light and turns a knob until the light stops flashing.
  5. 5.Blood tests-To measure blood levels of lutein and other carotenoids, liver function, cholesterol and triglycerides.

Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • Men and women aged 60 years or older.
  • Patients ranging from no AMD with little or no drusen in either eye through end stage AMD (geographic atrophic, retinal pigment epithelial detachment, or other signs of neovascular/exudative disease) in their eye with worst disease will be eligible.
  • The ability to understand and sign an informed consent form prior to enrollment.

You may not qualify if:

  • Ocular disease which confounds assessment of the retina other than age-related macular degeneration including diabetic retinopathy, central serous choroidopathy, optic atrophy, retinal vein occlusion, active uveitis, significant explained or unexplained visual field loss, or any other type of retinopathy or retinal degeneration.
  • Chronic requirement for any systemic or ocular medication for other diseases such as glaucoma.
  • Patients has regularly been taking lutein supplements during the last 3 months or is currently taking lutein supplements. The daily use of the new Centrum or Centrum Silver or other similar multivitamins will be allowed but should be limited to a maximum of twice a day.
  • Abnormal liver function tests.
  • Inability to be followed for a period of 1 year.
  • Acute potentially life-threatening illness such as heart attack in the last year, malignant cancer or blood disease not in remission.
  • History of lung cancer.
