Our research is focused on studying the structure and function of the normal and diseased retina at the level of single cells in the living human eye. We use advanced optical imaging techniques with adaptive optics to study the cellular mosaics of the retina, from the retinal pigmented epithelial cells that line the back of the eye, to the photoreceptors that absorb light and initiate the first step of seeing, to the retinal ganglion cells whose parallel neural circuits process visual information and send it along to the rest of the brain. Visual function can be impaired when any of the different classes of cells in the retina are damaged or lost from causes such as genetic abnormalities, disease or trauma. Some specific diseases of focus for us include age-related macular degeneration, glaucoma, and inherited retinal degenerations ...

    Vision Walk

    Vision Walk : Pittsburgh Chapter

    October 29th, 2022

    Dr Rossi along with Dr Ian Conner were the medical co-chairs for this year's 15th annual Vision Walk. A yearly event sponsored by the Foundation Fighting Blindness Pittsburgh chapter, held at the Great Lawn in Pittsburgh's North Side. The Foundation’s goal is to drive the research that will lead to preventions, treatments, and vision restoration for the spectrum of degenerative retinal diseases, specifically macular degeneration – including age related macular degeneration, retinitis pigmentosa, Usher syndrome, Stargardt disease and Leber congenital amaurosis (LCA). Together these conditions affect more than 10 million Americans and millions more throughout the world. During its now 50-year history, the Foundation has raised over $856 million in support of its effort to reverse blindness and restore vision. To learn more about the foundation please visit :
