A 73-year-old man presented with torsional diplopia. With major amblyoscope he measured 10 degrees of incyclotropia in primary position and 20 degrees of incyclotropia in downgaze. The patient had undergone temporal transposition of the left inferior rectus muscle in order to reduce incyclotropia in downgaze. Postoperatively, incyclotropia was reduced to 8 degrees. However, he complained horizo...

of elevation, fixation was eccentric, and there were nystagmoid movements in this eye. There was slight ptosis, the left interpalpebral fissure being 9 mm. at its highest point and the right 10 mm. The action of the levator palpebrae superioris was good. There was marked secondary contracture of the inferior rectus muscle. Operative intervention was carried out in two stages with a five-week in...

Port site wound infection, abdominal wall hematoma and intraabdominal abscess formation has been reported after laparoscopic appendicectomy. We describe here a rectus sheath abscess which occurred three weeks after the laparoscopic appendicectomy. It was most likely the result of secondary infection of the rectus sheath hematoma due to bleeding into the rectus sheath from damage to the inferior...

OBJECTIVE To seek evidence for causative secondary changes in extraocular muscle volume, cross-sectional area, and contractility in superior oblique (SO) palsy using magnetic resonance imaging, given that vertical deviations in SO palsy greatly exceed those explained by loss of SO vertical action alone. METHODS High-resolution, quasi-coronal orbital magnetic resonance images in target-control...

PURPOSE It has been proposed that the lateral rectus (LR), like many skeletal and craniofacial muscles, comprises multiple neuromuscular compartments subserving different physiological functions. To explore the anatomic potential of compartmentalization in all four rectus extraocular muscles (EOMs), evidence was sought of possible regional selectivity in intramuscular innervation of all rectus ...

FIG. I Superior and inferior rectus muscles are displaced temporally, the nasal tip of each muscle being attached at the temporal end of the original insertion and the temporal tip being attached at the upper or lower end of the lateral rectus. The direction of the vertical rectus muscles is thereby changed, so that they abduct instead ofadducting. The operation is completed with a recession of...

OBJECTIVE Establish criteria for the diameters of normal extraocular muscles using computerized tomography in a Thai population. MATERIAL AND METHOD Diameters of extraocular muscles (medial, lateral, superior complex, and inferior rectus) were calculated for 200 patients on coronal direction of screening paranasal sinuses. The effects of age and sex were also analyzed. RESULT Normal ranges ...

ment was recommended, but the patient initially refused. As the clinical findings did not change during follow-up, surgery was performed in August 2014. Restriction of the inferior rectus muscle of the left eye was confirmed through the forced duction test. During surgery, conjunctival scarring over the inferior rectus muscle was noted, in addition to a linear scar along the medial border of th...

PURPOSE Our goal was to determine whether the extraocular muscles in patients with chronic progressive external ophthalmoplegia (CPEO) could be distinguished from those of age-matched control subjects by MR imaging. METHODS Nine patients with CPEO and eight age-matched healthy control subjects were studied. The extraocular muscles of eight of the patients (16 eyes) and all the control subject...
