Overview

I am an ophthalmologist dedicated to the study of retinal diseases in children and adults with special passion for genetics and inherited eye disorders. I was born and raised in Ecuador, where my father, one of the first retina specialist in the country, motivated me to do research to find cures for untreatable conditions. I am truly happy to have the opportunity to serve patients with retinal diseases and strive to provide the best care possible.

I was born and raised right here in Durham, NC. After attending college at Duke, I ventured north to Boston, where I completed most of my medical training, and was fortunate to meet and marry the love of my life, my husband Neil (also on faculty as a cardiologist here at Duke). I returned to Durham for my Glaucoma fellowship, briefly joined the faculty “across the street” at UNC-Chapel Hill, and then returned “home” to Duke Eye Center in 1995, where I have been on the faculty ever since. Dual fellowship-trained in both Pediatric Ophthalmology and Strabismus as well as in Glaucoma, I have a clinical and research focus on pediatric glaucoma and cataracts, as well as retinopathy of prematurity, but enjoy providing care for myriad pediatric problems of the eyes, including treatment of “grown children” with ocular alignment issues. My modus operandi is very simple – I simply try hard to treat each and every patient the way I would like someone to treat me. It works every time, and I am privileged to be a clinician and educator at Duke Eye Center and in Duke University Health System. Dr. Freedman is rated as an Elite provider by MediFind in the treatment of Strabismus. Her top areas of expertise are Retinopathy of Prematurity, Strabismus, Brown Syndrome, Trabeculectomy, and Cataract Removal.
