The USC Roski Eye Institute clinicians are making great strides in protecting patient’s vision through conducting translational research in the epidemiology of eye disease. Rohit Varma, MD, MPH, professor and chair of the Department of Ophthalmology, director of the USC Roski Eye Institute, established the USC Roski Eye Institute Ocular Epidemiology Center, and has devoted his career to conducting community health-based studies that have changed our approach to diagnosis and treatment of eye diseases. The USC Ocular Epidemiology Center’s mission is to better understand the underlying pathologies and risk factors associated with different eye conditions and eye diseases (such as visual impairment and blindness, lens opacities, age-related macular degeneration (AMD), diabetic retinopathy and glaucoma) among different racial/ethnic aging populations. The potential to dramatically reduce the personal and socioeconomic burden of vision loss is possible, as these studies have led to early diagnosis and prevention of eye disease. Dr. Varma’s longitudinal studies are the largest in the world and have focused on children and adults. He is the principal investigator of 3 large NIH/National Eye Institute (NEI) -funded studies of eye disease in ethnic populations: Los Angeles Latino Eye Study (LALES), the Chinese American Eye Study (CHES) and the African American Eye Study (AFEDS). Dr. Varma was also the PI for the NIH/NEI funded Multi-Ethnic Pediatric Eye Diseases Study (MEPEDS). These studies have provided insights into improved strategies for public health interventions, and as a result, have had direct impact on health care policy in America.
