Functional imaging of human extraocular muscles in head tilt dependent hypertropia.
PURPOSE Although alteration in hypertropia induced by head tilt is considered a clinical criterion for diagnosis of superior oblique (SO) palsy, the mechanism of this head-tilt-dependent hypertropia (HTDHT) is unclear. In this study, magnetic resonance imaging (MRI) was used to study extraocular muscle (EOM) responses to head tilt in HTDHT. METHODS Orbital MRI was used to study 16 normal subj...
متن کاملSite-dependent distribution of macrophages in normal human extraocular muscles.
PURPOSE Clinical data indicate that extraocular muscles have different susceptibilities for some orbital immune disorders depending on their anatomic location. The resident immunocompetent cells may be important mediators in the local pathogenesis of such disorders so the distribution of these cells was studied in extraocular muscles obtained from normal human donors. For comparison skeletal mu...
متن کاملMagnetic resonance imaging of human extraocular muscles in convergence.
Extraocular muscle (EOM) paths during asymmetrical convergence were evaluated by tri-planar, contrast-enhanced magnetic resonance imaging of the orbits of eight young adults during binocular fixation of a target aligned to one eye at 800 and 15 cm distance. Cross sections and paths of EOMs were determined from area centroids. In convergence, the aligned eye rotated and translated negligibly, wh...
متن کاملIntermediate filaments in the human extraocular muscles.
PURPOSE To investigate the distribution of the intermediate filament (IF) proteins desmin, vimentin, and nestin in human extraocular muscles (EOMs). METHODS Healthy adult EOM samples were serially sectioned (5 and 1 μm) and processed for immunohistochemistry, with specific antibodies (Abs) against desmin, vimentin, and nestin and different myosin heavy chains (MyHCs), including the newly char...
متن کامل3223 Tendon receptors in human extraocular muscles
Oculomotor disturbances commonly occur as manifestations of Graves’ Oohthalmomthv. We investieated the outcome of this disorderfollowing e&ernal-beam orbital radiotherapy. We conducted a prospective study on 15 patients to assess the extent of ophthalmopathy by clinical evaluation, and measurement of the amplitude of gaze and the thickness of the extraocular muscles on computed axial tomography...
