People invited to participate in macular degeneration study

University of Iowa Health Care researchers invite people to participate in a study on age-related macular degeneration (AMD). The special research day includes two sessions, 8 a.m. and 10 a.m., Wednesday, Sept. 26, at the Council Bluffs Senior Center, 900 South 6th St., in Council Bluffs. Each session will last approximately two hours. The registration deadline is Friday, Sept. 21, and registration can be completed in person at the senior center or by calling (712) 323-5995.

Two types of participants are eligible for the study. Participants without age-related macular degeneration must be age 75 or older. These individuals do not need to have perfect vision to participate but they should not have an extensive history of eye problems. Participants with AMD may be any age. The researchers also will welcome families with a large number of people affected by AMD (five to 10 affected family members).

Participants will be asked to answer a brief health questionnaire, have two blood samples drawn and have a picture taken of the back of their eyes. Because participants will have their eyes dilated for the photograph, they should arrange to have a family member or friend provide transportation.

The study is being led by Gregory Hageman, Ph.D., and Edwin M. Stone, M.D., Ph.D., both UI professors of ophthalmology and visual sciences. The researchers aim to identify the genes and other factors responsible for AMD, the leading cause of irreversible vision loss in the United States.

For additional information about the study, call the UI Center for Macular Degeneration at (319) 384-9270.
