Biography and Education


Vivek R. Patel, MD, received his undergraduate and medical degrees, with distinction, from the University of Saskatchewan. He completed his internship and residency training in ophthalmology at McGill University, where he served as chief resident, prior to completing fellowship training in neuro-ophthalmology at the University of Southern California. Dr. Patel came to us from the Wilmer Eye Institute, Johns Hopkins University School of Medicine, where he was an assistant professor of neuro-ophthalmology.

Board-certified in the United States and Canada, Dr. Patel is an associate professor of ophthalmology and director of the Neuro-Ophthalmology and Adult Strabismus Program at the USC Roski Eye Institute, Keck School of Medicine. He also serves as the Residency Program director and Neuro-Ophthalmology Fellowship director at USC. He is currently a board examiner for the Royal College of Physicians and Surgeons of Canada. He is a co-editor of Walsh and Hoyt’s Clinical Neuro-Ophthalmology: The Essentials, 3rd Edition, which is widely recognized as one of the pre-eminent textbooks in the field.

Dr. Patel has considerable expertise and experience in the surgical management of complex adult strabismus including the use of adjustable sutures and transposition techniques.

Research Interests:

Dr. Patel’s major academic interest is in the study and imaging of the visual pathways. He has considerable expertise and experience in interpreting visual fields, microperimetry, and optical coherence tomography scans, in addition to the clinical evaluation and identification of patients with visual loss due to optic neuropathies and intracranial disorders. Dr. Patel is a co-investigator on a multidisciplinary collaboration involving ultra-high resolution imaging of the visual pathways and how they are affected in various optic nerve and retinal disorders.
