Persistent Upgaze Restriction after Orbital Floor Fracture Repair

Abstract

Here we present two cases of marked postoperative upgaze restriction after successful repair of orbital floor fracture and release of inferior rectus entrapment. In both cases, follow-up imaging showed enlargement of the inferior rectus, and gradual resolution of gaze limitation was observed over several months of conservative management. Thus, in patients with postoperative findings suggestive of residual inferior rectus entrapment, follow-up imaging is indicated prior to returning to the operating room. With a markedly swollen inferior rectus muscle but no radiographic evidence of residual muscle entrapment in the fracture, a trial of conservative management may be warranted.
