Background

Jithin Yohannan, M.D., M.P.H. is Boone Pickens Rising Professor of Ophthalmology at the Wilmer Eye Institute, Johns Hopkins University School of Medicine. His practice specializes in medical, laser, and surgical treatment of glaucoma, focusing on minimally invasive glaucoma surgery (MIGS) and new glaucoma surgical devices. He also performs both routine and complex cataract surgery. Dr. Yohannan also specializes in the surgical management of complex problems of the anterior segment (front of the eye). These problems include issues arising after trauma or prior surgery gone wrong, such as dislocated intraocular lenses (IOL) or iris and pupil defects.

Dr. Yohannan earned his bachelor’s degree in biochemistry from New York University, where he graduated summa cum laude. He then received his medical and master of public health degrees from Johns Hopkins University. He completed an ophthalmology residency at the Wilmer Eye Institute, Johns Hopkins University School of Medicine. From there, he served as a fellow in glaucoma and advanced anterior segment surgery at the University of Toronto. Dr. Yohannan then returned to Wilmer to serve as Assistant Chief of Service for one year, after which he joined the glaucoma division. 

Dr. Yohannan holds a joint appointment at the Malone Center of Engineering in Healthcare. He leads a lab that focuses on using artificial intelligence algorithms to aid in the diagnosis and management of glaucoma patients. He has a background in biostatistics, epidemiology, and mathematics, which enables this effort. His group has developed AI models that forecast high-risk glaucoma patients and is focused on translating these models for clinical application. Additionally, his group aims to understand how we can optimize structural and functional glaucoma testing to improve the detection of glaucoma worsening. 

Dr. Yohannan also has a clinical and research interest in novel surgical devices used to treat glaucoma. These devices promise to make glaucoma surgery safer and easier to recover from.
