During this study study, patients will be asked to not take more than two tablets each day of multivitamins that contain lutein. The vitamin supplements will be provided as pills that represent one of two vitamin regimens given on a random basis: either lutein and zeaxanthin with DHA or lutein and zeaxanthin without DHA added. The amounts would be 10 mg/day of lutein and 2 mg/day of zeaxanthin, with or without 1 g/day of DHA. Patients will return to the study center for follow-up visits at 1 month, 3 months, 6 months, and 9 months. During those visits, some of the examinations done earlier will be repeated so that the researchers can evaluate the effects of supplements on patients' eyes. Patients will also be watched for possible side effects from the vitamins supplements. Lutein and zeaxanthin supplements are considered to be safe with possible minor side effects, such as headaches and difficulty in swallowing the tablets. Fish oil or DHA supplements may also cause abdominal discomfort.
