Pediatric Ophthalmology Research

The Division of Ophthalmology is committed to advancing care through research. Our specialists are involved in a variety of projects that encompass multiple aspects of pediatric ophthalmology, including amblyopia, strabismus, cataracts, genetic eye disorders, ocular tumors, retinopathy of prematurity, visual examination, ocular imaging and education. This is being accomplished not only through our own institution’s research department, but also through collaborations with other academic centers and integrated national networks. Our division takes great care in compliance with federal, state and institutional regulations with regards to research to provide the best safety and care towards our patients.
