Additional Areas of Focus
Dr. Couser has provided the following conditions as areas of focus. Please note that we may not have enough data to validate their experience in some of these conditions.
Clinical Research
Clinical research consists of overseeing clinical studies of patients undergoing new treatments and therapies, and publishing articles in peer reviewed medical journals. Providers who actively participate in clinical research are generally at the forefront of the fields and aware of the most up-to-date advances in treatments for their patients.
The Johns Hopkins Hospital
Peter A. Campochiaro, M.D. is the George S. and Dolores Doré Eccles Professor of Ophthalmology and Neuroscience at the Wilmer Eye Institute, Johns Hopkins University School of Medicine. He is a clinician-scientist who directs a research laboratory and conducts clinical trials. His laboratory research is directed at understanding the pathogenesis of ocular neovascularization and excessive retinal vascular permeability, and the mechanism of cone cell death in inherited retinal degenerations. He helped to determine the importance of vascular endothelial growth factor (VEGF), hypoxia-inducible factor-1, and Tie2 in retinal and choroidal vascular diseases. The clinical trial group under Dr. Campochairo provided the first demonstration of the benefits of suppression of VEGF in diabetic macular edema and retinal vein occlusion. He has developed strategies for sustained suppression of VEGF that are currently being tested in clinical trials. Dr. Campochiaro trained at the University of Notre Dame, Johns Hopkins School of Medicine, and the University of Virginia. He did a vitreoretinal fellowship and research fellowships at Johns Hopkins and joined the faculty of the University of Virginia in 1984. He became professor of Ophthalmology and Neuroscience at the Wilmer Eye Institute, Johns Hopkins in 1991. Dr. Campochiaro is highly rated in 18 conditions, according to our data. His clinical expertise encompasses Retinal Vein Occlusion, Late-Onset Retinal Degeneration, Age-Related Macular Degeneration (ARMD), Trabeculectomy, and Vitrectomy. Dr. Campochiaro is board certified in American Board Of Ophthalmology. Dr. Campochiaro is currently accepting new patients.
