Study Summary
Age-related macular degeneration (ARMD) affects older Americans and can lead to irreversible blindness. Although the cause if ARMD is unclear, it appears to be a condition that is affected by both genetic and environmental influences. The purpose of this study is to examine an Amish community to investigate genetic factors in the development of ARMD. Study participants will be 1,000 members, ages 50 and older, of the Old Order Amish community in Lancaster and Franklin counties in Pennsylvania. Each will undergo a 30-minute dilated eye exam during which an ophthalmologist or optometrist will take digital images of the macula and optic disc. Depending on the results of their eye exam, participants may be asked to give a blood sample as well. They will also complete a brief questionnaire about personal exposure related to occupation, sunlight and smoking.
