Timothy Flood, MD, FACS – Emeritus

“Taking care of patients who have retinal problems and helping to relieve their anxiety over the health of their eyes is very rewarding. Research is also important to me. To be able to take the knowledge you have gained through a clinical trial and change the way physicians treat patients is very exciting. Here at Illinois Retina, we’re helping people, having fun doing it and creating new knowledge at the same time.”
