Dr. Linda Dagi is the Director of Adult Strabismus at the Boston Children’s Hospital and Associate Professor of Ophthalmology at Harvard Medical School. She attended Harvard College and Harvard Medical School, and completed an internship in internal medicine and residency in ophthalmology at Georgetown University Hospital. She then completed fellowships in Neuro-Ophthalmology at the National Eye Institute and Pediatric Ophthalmology and Adult Strabismus at Boston Children’s Hospital.   She has joint appointments at Boston Children’s Hospital and Massachusetts Eye and Ear.

Dr. Dagi has pioneered the development of a number of novel surgical techniques in the field of complex strabismus. She has published broadly and lectured nationally and internationally in this field.

She is the Chairman of the Adult Strabismus Task Force for the American Association of Pediatric Ophthalmology and Strabismus and is the lead author on the Preferred Practice Plan for Adult Strabismus for the American Academy of Ophthalmology.

She was the first female ophthalmologist invited to join the Association for Research in Strabismus, familiarly know as  “Squint” Club.  This international society of leaders in the field of strabismus surgery was inaugurated in 1949 and invites no more than one new member yearly.

Clinical Interests

Dr, Dagi has a particular interest and expertise in the treatment of complex strabismus and double vision resulting from cranial nerve palsies, high myopia and aging of the eyes, as well as thyroid eye disease.  She has pioneered the development of a number of novel surgical techniques in this realm.

As a pediatric ophthalmologist, she treats complex strabismus disorders in children, ptosis in children, and provides consultation to the craniofacial service at Boston Children’s Hospital.

Research Interests

Dr. Dagi's research iinvolves the development of novel and adjustable surgical approaches to treat complex strabismus disorders, and the use of high-resolution orbital imaging to better understand these disorders.
