BACKGROUND A case report of Hashimoto's thyroiditis-associated ophthalmopathy that masqueraded as double elevator palsy in 1 eye. CASE PRESENTATION A 54-year-old woman presented to our strabismus clinic with diplopia for 1 year. She was diagnosed with double elevator palsy in the left eye. The forced duction test yielded positive findings for the inferior rectus of the left eye; hence, comput...

Stimulation of the inferior oblique and superior rectus branches and of the whole oculomotor nerve was carried out in cats while recording either gross or unit activity within the region of the oculomotor nucleus. On the basis of a number of criteria, unit responses were selected to represent antidromic activation of cell bodies in that nucleus. For the superior rectus, these were found to be l...

Rectus sheath hematoma is an uncommon but well-described complication of a tussive paroxysm. It is an accumulation of blood within the sheath of the rectus abdominis secondary to disruption of the epigastric vessels or the rectus muscle and is often misdiagnosed as acute abdomen. Increases in the number of elderly patients and the use of therapeutic anticoagulation may increase ...

' 2003 Canadian Medical Association A71-year-old diabetic man was admitted with a 2-day history of acute left lower abdominal pain. He denied any history of trauma or sport activity before admission. On examination he was normotensive and apyrexial. An exquisitely tender abdominal wall mass was felt at the left iliac fossa. The abdominal pain increased and the mass became more prominent when th...

A 44-year-old man was referred to our department with diplopia, periorbital swelling and haematoma of the left eye after orbital trauma due to a punch. During the examination, mild enophthalmos, hypertropia and a total absence of infraduction were observed. An orbital computed tomography (CT) scan demonstrated a left orbital floor blow-out fracture, with caudal herniation of periorbital fat and...

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...

A 54-year-old male sustained a fractured right orbital floor 33 years ago, which was treated with a silastic implant. His diplopia never resolved, and he presented to us with an acute orbital cellulitis. Computerized tomography showed a displaced inferior rectus and entrapment of both inferior and medial recti. The implant was removed surgically via a Caldwell-Luc approach and his diplopia comp...
