The data is collected through detailed interviews, questionnaires and blood samples that are studied for genetic abnormalities. Analysis of the samples is underway to find out if these family members might have a defect in the ABCR gene. More families are needed for the study, which has been expanded to include non-affected family members. The center is analyzing the DNA of family members with AMD to identify the cause of and, ultimately, new therapies, for macular degeneration. Families with at least three living blood relatives with AMD are being enrolled.
Volunteers receive fundus photography and DNA analysis at no cost.
The study, supported by a grant from the National Eye Institute, has already pinpointed the location of one gene that causes age-related macular degeneration.
