About Us




Retina Associates of Kentucky was founded by 
William J. Wood, MD   in Lexington, Kentucky in 1975.  After completing his undergraduate and medical school education at the University of Kentucky's College of Medicine and his residency at the prestigious Wilmer Ophthalmological Institute at Johns Hopkins University, Dr. Wood received the Heed Fellowship Award at the Massachusetts Eye and Ear Infirmary at Harvard University.  He strongly considered returning to the Wilmer Institute, but chose instead to return to his home in Lexington to start his retina practice as well as work teaching as a part-time faculty member of the Department of Ophthalmology at the University of Kentucky.  He was promoted to Clinical Professor and led the developing retina subsection at the University for many years.  

In establishing the retina practice, Dr. Wood insisted in excellence in everything from the most advanced equipment to the most highly trained surgeons.  He and his partners have insured that every associate that has joined the practice have the highest qualifications, both personally and professionally.  Dr. Wood started the Low Vision Services of Kentucky division of Retina Associates of Kentucky and was the founding chairman of the Macular degeneration Institute as well.  He has served as study surgeon or clinical investigator in many clinical studies and is recognized in the "Best Doctors in America"® and "America's Top Ophthalmologists"®.  Dr. Wood serves on the Board of Governors of the Wilmer Eye Institute at Johns Hopkins.

Dr. Isernhagen graduated in the top 5% of his medical school class and had many options as to where to practice, but it was the beauty of the bluegrass and the chance to work with a strong leader in the field of vitreoretinal disease that made Dr. Isernhagen call Kentucky his home.  Dr. Isernhagen's main treatment and research interest is the care and management of age-related macular degeneration; he has served as Principle Investigator in numerous clinical trials and accumulated many professional awards over the years including œBest Doctors in America and œAmerica's Top Ophthalmologists.
