David L. Guyton, M.D., is the Zanvyl Krieger Professor of Ophthalmology. He is internationally known for his contributions, inventions, and teaching in the fields of ophthalmic optics, clinical refraction, potential acuity testing, and ocular motility. His clinical practice in strabismus is heavily surgical, both pediatric and adult, with emphasis on re-operations and cyclovertical surgery, using adjustable sutures. With adults comprising more than 80 percent of his strabismus surgical cases, Dr. Guyton has contributed significantly to our knowledge of strabismus complications from local anesthetics, the “inverted Brown pattern,” the “dragged-fovea diplopia syndrome,” theories of how and why strabismus develops in the first place, and how and why it can change over time. Dr. Guyton is currently developing automated instruments for the vision screening of infants and children. Dr. Guyton is rated as a Distinguished provider by MediFind in the treatment of Amblyopia.
