To report the clinical features of strabismus associated with Graves' orbitopathy, and the results of surgery with adjustable suture under drop anesthesia.


The charts of 13 patients who had surgical treatment for strabismus related to Graves' orbitopathy at Hospital das Clínicas of University of São Paulo were retrospectively reviewed. Ocular motility, sensorial examination and the follow-up after strabismus correction were studied.


Preoperatively, the most common type of deviation was esotropia with hypotropia. Adjustable recession was done in nine patients and a second surgery occurred in 3 patients. After follow-up of at least six months, 8 of 13 patients were orthotropic or had a small phoria with some degree of binocular vision.


In this study, 62% (8/13) of patients showed hypotropia with esotropia, probably because fibrotic and restrictive muscles (medial and inferior rectus). In nine of 13 patients adjustable recession with a good postoperative alignment of the eyes was performed. Adjustment of strabismus surgery under drop anesthesia in patients with Graves' orbitopathy was successful in restoring binocular vision with minimum complications.
