ROCHESTER -- Dr. Robert W. Hollenhorst, 94, a Mayo Clinic physician and pioneer in neuro-ophthalmology, died Thursday (Jan. 10, 2008) in Rochester. Born Aug. 12, 1913, in St. Cloud, Minn., he attended St. Cloud State Teachers College, St. John's University, and the University of Minnesota Medical School. Dr. Hollenhorst began his career as an ophthalmologist at Mayo Clinic and professor at the Mayo Graduate School of Medicine. Some of his research described a phenomenon now known as "Hollenhorst Plaques." These cholesterol bodies, sometimes found in the blood vessels of the retina, are useful in diagnosing the risk of stroke and other circulatory problems.
