tanley Chang, M.D., is the former Edward S. Harkness Professor and Chairman of the Department of Ophthalmology at Columbia University Medical Center. He is also the K.K. Tse and Ku Teh Ying Professor of Ophthalmology. He is a specialist in vitreoretinal disorders and surgery and pioneered many of the surgical techniques currently used in this field.
Dr. Chang received a baccalaureate degree from the Massachusetts Institute of Technology, a Masters degree from the University of Pennsylvania, and completed his medical education at the College of Physicians and Surgeons of Columbia University. After fellowship, Dr. Chang joined the faculty of Department of Ophthalmology at Cornell University Medical School, where he became Professor of Ophthalmology. Appointed the Edward S. Harkness Professor and Chairman of the Department of Ophthalmology in 1995, he served as director of the Edward S. Harkness Eye Institute until 2012.
Dr. Chang has developed and pioneered several revolutionary surgical approaches to treat complicated forms of retinal detachment, improving outcomes for patients worldwide. He was the first to use perfluoropropane gas in the management of retinal detachments caused by scar tissue proliferation (PVR) on the retina. This gas is the most frequently used gas in vitreoretinal surgery. He developed perfluorocarbon liquids, a 'heavy liquid' used in flattening retinal detachment, and the related surgical techniques for vitreoretinal surgery. In collaboration with Avi Grinblat, he developed a panoramic viewing system and led in the worldwide adaptation by retina surgeons to this technique. In leading a world class Department and vision research institute, he continues to improve the clinical outcomes for patients through research and innovation. He is the recipient of several honors including the Hermann Wacker Prize from the Club Jules Gonin, Helmerich Prize from the American Society of Retinal Specialists, the Lifetime Achievement Award and the Secretariat Award from the American Academy of Ophthalmology, the Jackson Lecture and the Alcon Research Institute Award. Consistently named as one of America's best doctors, Dr. Chang was recently recognized as one of three physicians selected as National Physician of the Year by the Castle Connolly Guides (2008).
The Department of Ophthalmology is grateful to Dr. Chang for his exemplary and inspirational leadership during his time as Chair and Director of Ophthalmology. During his tenure, the department attracted a top-notch team of researchers and clinicians, developed new faculty practices in New York and New Jersey, more than doubled the number of surgical cases in the Eye Institute, and dramatically increased research funding. Dr. Chang remains an active member of the faculty and continues his patient care, research and teaching commitments.
