About

Dr. Efstathia Tzatha is pioneering the intersection of fluorescence-guided surgery and neural preservation, with a focused expertise in developing optical contrast agents for intraoperative nerve identification. Her landmark work on Rizedisben—a myelin-binding fluorophore that fluoresces under blue light (370–425 nm)—represents a significant advancement in minimally invasive surgery. By enabling real-time, high-contrast visualization of peripheral nerves, Dr. Tzatha’s research directly addresses the critical challenge of iatrogenic nerve injury during surgical procedures. Her 2025 study, which has already garnered 4 citations, establishes the foundational safety and efficacy parameters for this novel imaging agent, paving the way for its clinical translation. Beyond this core contribution, her work bridges molecular imaging and surgical oncology, aiming to improve patient outcomes through enhanced intraoperative decision-making. Dr. Tzatha’s research holds profound implications for fields ranging from colorectal and urologic surgery to neurosurgery, where preserving nerve function is paramount. Her innovative approach positions her as a rising leader in the development of next-generation surgical visualization technologies.
