Two cases of medial orbital fracture with medial rectus muscle entrapment are reported, one a bona fide blowout fracture. Review of the literature reveals six previous cases.
Clinically, patients complain of diplopia with lateral gaze and forced duction tests confirm medial rectus entrapment. Radiographic confirmation is best obtained with hypocycloidal tomography. Surgical therapy is indicated for diplopia or enophthalmus.
