Volunteers needed for research study - how blood vessels react

Penn State Milton S. Hershey Medical Center’s Kerstin Betterman, M.D., Ph.D., and Mary Lott, Ph.D., are studying if there is a relationship between blood vessels in the eyes and those in the brain and heart. Volunteers are needed for this study.

If researchers can see a relationship in the way that the blood vessels react to changes in blood flow and find that there is a difference in the way the blood vessels react in people who are healthy and people with diabetes, there is the potential that an eye device can be used to track overall vascular health.

Eligible volunteers will be between the ages of 21 and 75 and have type 2 diabetes; have had a stroke, heart attack or heart surgery; or have borderline diabetes (blood sugar level of 100-125); or be healthy with a BMI between 30-40.

Participation requires looking into an eye device similar to an eye test while breathing oxygen and a gas mixture with carbon dioxide. An ultrasound of the arteries is also completed while breathing the same gases.

Compensation is provided.

This research study, IRB 29480, has been approved by the Institutional Review Board, under federal regulations at Penn State Hershey Medical Center, Penn State College of Medicine.
