David Gritz, M.D., M.P.H. is a professor of ophthalmology at the Wilmer Eye Institute, specializing in complex cataract surgery, cornea transplantation and other anterior segment procedures.  

His research is largely focused on epidemiology and clinical trials. He was the principal investigator for The Northern California Epidemiology of Uveitis Study, the largest population-based cohort study of uveitis presently in the literature, as well as epidemiologic investigations into a number of other eye diseases. He was the principal investigator for the Antioxidants in Prevention of Cataracts Study, a large five-year randomized clinical trial examining the effect of antioxidant vitamins in the progression of cataracts. This study was the first of its kind in India and was a collaboration between the Francis I. Proctor Foundation/University of California, San Francisco and the Aravind Eye Hospital in Madurai, India.

Dr. Gritz received his medical degree from the University of Missouri - Kansas City School of Medicine and did his residency in ophthalmology at the University of Texas Health Science Center- San Antonio.
