About Linda Dagi, MD

Dr. Linda Dagi is the Director of Adult Strabismus at the Boston Children’s Hospital/Mass. Eye and Ear and Associate Professor of Ophthalmology at Harvard Medical School. She has joint appointments at Boston Children’s Hospital and Massachusetts Eye and Ear. Dr. Dagi is also the Director of Quality Assurance, Department of Ophthalmology and Ophthalmology Foundation Chair at Boston Childrens Hospital. 

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 Chair 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.

Dr. Dagi has contributed substantially to the development and refinement of two new surgical techniques for managing strabismus from sixth nerve palsy, Duane syndrome, and third nerve palsy.  She has employed high resolution orbital magnetic resonance imaging to demonstrate the anatomical relationships resulting from these procedures.

She is the Principal Investigator for a series of studies designed to compare the  ophthalmic impact on patients with unicoronal synostosis treated by endoscopic strip craniectomy and helmeting (ESCH) rather than by fronto-orbital advancement (FOA). She demonstrated that those treated with ESCH had reduced astigmatism, amblyopia and strabismus, and a more favorable craniofacial outcome. 

She also studies complex strabismus in patients with syndromic craniosynostosis or other craniofacial disorders.  Through the use of high resolution orbital imaging and 3D modeling, she has demonstrated  that exaggerated V-pattern strabismus has it’s origins at the orbital apex.  She has studied surveillance of impending optic neuropathy in this population with OCT and prVEP.

As Director of Quality Assurance, she supervised the development of a goal-determined paradigm to evaluate outcomes of surgery for esotropia and exotropia.  This methodology requires surgeons to prospective rank four possible goals of surgery on the day of each procedure.
