Overview
I am a Comprehensive Ophthalmologist who specializes in patients with cataracts and cataract surgery related problems. When it comes to treating patients, I like to have a clear understanding of their problems and expectations so that I can explain what I can reasonably do for them. Seeing the satisfaction of a happy patient after successful cataract surgery is my favorite part of my job. I have always enjoyed working and interacting with people and feeling like I can improve their lives. I enjoy being in a scientific field and the optics, anatomy and skills required to become an ophthalmologist drew my interest after my grandfather underwent cataract surgery while I was a teenager. Outside of work I enjoy running, cycling, triathlons and ballroom dancing.

Clinical Research
Clinical research consists of overseeing clinical studies of patients undergoing new treatments and therapies, and publishing articles in peer reviewed medical journals. Providers who actively participate in clinical research are generally at the forefront of the fields and aware of the most up-to-date advances in treatments for their patients.
Duke Eye Center
I am an ophthalmologist specializing in both pediatric and neuro-ophthalmology. My expertise is in the diagnosis and treatment of various types of neurological conditions affecting the eyes of both adults and children. My clinical interests include pediatric and adult nystagmus, strabismus, brain tumors, autoimmune demyelinating diseases, spina bifida, craniosynostoses, hydrocephalus, neonatal hypoxic ischemic injury, spina bifida, cortical visual impairment, papilledema, idiopathic intracranial hypertension (pseudotumor cerebri) and all optic neuropathies. The large majority of my patients are children with/or at risk for neurologic disease or adults with developmental delay. My clinic visits often include ancillary testing such as visual fields and optical coherence tomography, which help me assess if there is a risk for vision loss. I like to try to avoid invasive testing and procedures or testing that requires anesthesia or sedation when possible. In my pediatric clinic, I like to collect and use old fashioned mechanical toys to test eye movements, which younger children usually enjoy. I will often have small prizes for younger (and older) children at the end of the visit. Dr. Dairi is rated as a Distinguished provider by MediFind in the treatment of Papilledema. Her top areas of expertise are Papilledema, Increased Intracranial Pressure, Optic Nerve Atrophy, Brown Syndrome, and Trabeculectomy.

Duke Eye Center
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 Papilledema. Her top areas of expertise are Retinopathy of Prematurity, Strabismus, Brown Syndrome, Trabeculectomy, and Cataract Removal.
