About Phillip Yuhas
I am an optometrist on faculty at The Ohio State University College of Optometry. As such, I teach the College's course on glaucoma and in the College's clinics and conduct vision science research. My research is focused on the structure and function of the retina, the thin film of neuronal tissue that lines the back of the eye and allows us to see.
