title: Traumatic ocular hypotonia encountered during reduction of multiple facial fractures.
abstract: There are many different potential causes of globe hypotonia after ocular surgery. To the best of our knowledge, this is the first report of traumatic intraoperative hypotonia during orbital floor exploration and repair. We present a case involving a patient with a history of cataract surgery who developed intraoperative hypotonia when undergoing ocular manipulation during the exploration of multiple facial fractures.
