Research Summary

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.
