Computed tomographic (CT) findings in four patients with isolated blow-out fracture of the medial orbital wall are reported. CT delineated the fracture site and its extent in each case, and clearly demonstrated medial rectus muscle entrapement in two. This was confirmed by surgery. CT was found superior to poly tomography and proved to be the best radiologic means for the diagnosis of medial or...

The aim of this investigation was to study the effect of non-involved-side exercise on the involved (paretic) leg-muscle of patients with stroke. Each of the ten adults studied attempted to perform, while seated, a predetermined sequence of the following actions : (1) a voluntary knee extension on the involved side; (2) a maximal, isometric knee-flexion on the non-involved side; (3) a maximal, ...

PURPOSE The aim of the present study was to assess, in cadavers, the resistance to medial traction of the posterior and anterior layer of the rectus abdominis muscle sheath. METHODS An anatomical, prospective, self-controlled study was carried out in 20 male cadavers. An evaluation of the tension of the posterior and anterior layers of the rectus abdominis muscle sheath was performed followin...

We discuss here an interesting case of strabismus, due to bilateral absent medial rectus muscle associated with brain anomalies, and its surgical management.

INTRODUCTION Endoscopic surgical techniques improve the surgeon's view of sinus structures but are subject to extraocular muscle complications that cause permanent diplopia. METHODS A series of 15 patients with strabismus following endoscopic sinus surgery was reviewed retrospectively to characterize the type of muscle injury and report the results of surgical correction. RESULTS A variety ...

Purpose To analyze in a frontal-eyed mammal (cat) the postnatal development of palisade endings in extraocular muscles (EOMs) and to compare the spatiotemporal and quantitative patterns of palisade endings among individual rectus muscles. Methods Cats of different ages ranging from birth to adult stage were studied. EOM whole-mount preparations were fluorescently labeled using six combination...

Recent studies have implicated exotropia as a risk factor for schizophrenia. We determined whether schizophrenia biomarkers have abnormal levels of expression in extraocular muscles from patients with strabismus and explored whether differences in gene expression between medial and lateral rectus muscles may explain the specific association of schizophrenia with exotropia but not esotropia. Sam...

A 54 year-old Caucasian gentleman with history of diabetes presented to emergency department with complaints of facial swelling for one week and left orbital pain of one day duration. The patient underwent computed tomography (CT) scan of head with intravenous contrast which revealed infl ammation of left medial rectus muscle and cellulites of medial left orbital coronal space deep to and surro...
