Bryce Chiang, M.D., Ph.D., is an assistant professor of ophthalmology and a glaucoma specialist at the Wilmer Eye Institute, Johns Hopkins Medicine East Baltimore location. His clinical interests include the medical and surgical management of glaucoma and cataract. After receiving his combined bachelor’s/master’s degrees in biomedical engineering from The Johns Hopkins University, Dr. Chiang completed joint M.D./Ph.D. degrees at the Emory University School of Medicine. During his doctorate in biomedical engineering at the Georgia Institute of Technology, Dr. Chiang became interested in ophthalmology through his research in ocular drug delivery. He served as a medicine intern at Highland Hospital in Oakland, California, and completed his ophthalmology residency, glaucoma fellowship and innovation fellowship at the Byers Eye Institute at Stanford University. Dr. Chiang’s research interests include targeted ocular drug delivery, specifically within the suprachoroidal space and to the optic nerve head. He studied the pharmacokinetics of microneedle injections into the suprachoroidal space while pursuing his doctorate at Georgia Tech, and maintains an interest in the suprachoroidal space as a means of altering disease trajectory. Furthermore, despite the optic nerve head being the site of disease in optic neuropathies, no therapies exist that treat the optic nerve head. By directly treating the diseased tissue, targeting therapeutics to the optic nerve head may enable paradigm shifting therapies for optic neuropathies. Targeted delivery to the optic nerve head may also serve as a research tool to query the pathogenesis of glaucoma.
