Virginia A. Miraldi Utz, MD
is a pediatric ophthalmologist who works closely with faculty within the Ophthalmology and Visual Science Research Department and Division of Human Genetics. Her research interests are in nosology of ophthalmic genetic disorders and syndromes including retinal dystrophies and mitochondrial disorders.
Assistant Professor, UC Department of Ophthalmology
Pediatric eye diseases such as amblyopia, cataracts and strabismus; diagnosis and management of genetic eye disorders and syndromes (retinal dystrophies such as retinitis pigmentosa, Stargardt disease, ocular malformations and mitochondrial disorders); pediatric uveitis and ocular inflammation.
Dr. Virginia Miraldi Utz, MD, FAAP, is an assistant professor of pediatric ophthalmology at the Abrahamson Eye Institute of Cincinnati Children’s Hospital Medical Center. She completed her undergraduate degree in biochemistry and religious studies at The College of Wooster (Wooster, Ohio) and Kanda University (Chiba, Japan). She received her Doctor of Medicine from Case Western Reserve University School of Medicine in Cleveland, Ohio, where she was served as co-president of the Alpha Omega Alpha Society chapter. During her residency at University Hospitals Case Medical Center, she was awarded the Ocular Immunology and Uveitis Foundation Travel Grant for her basic science research in ocular microbiology and immunology and the Humanism in Ophthalmology Award. She completed her fellowship training in pediatric ophthalmology and adult strabismus at the Cleveland Clinic Cole Eye Institute. She recently completed additional clinical training in the field of ocular inflammation and uveitis preceptorship to serve patients with juvenile idiopathic arthritis and related disorders.
Dr. Miraldi Utz specializes in the management of pediatric eye disorders such as amblyopia, strabismus, and pediatric cataracts. She has special clinical and research interests in ocular inflammatory disease and ophthalmic genetic disorders, including ocular malformations and retinal dystrophies. Dr. Miraldi Utz has published multiple research articles in peer-reviewed journals, as well as having contributed abstracts and presentations at a number of professional association meetings. She is a peer reviewer for several journals, including Ophthalmic Genetics, Molecular Vision, and British Journal of Ophthalmology. She is a member of American Association for Pediatric Ophthalmology and Strabismus, American Academy of Ophthalmology, American Uveitis Society, Ophthalmic Genetic Study Club, International Society for Genetic Eye Diseases and Retinoblastoma, and Fellow of the American Academy of Pediatrics.
