' 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...

PURPOSE We wanted to examine the effect of graded recession and anteriorization of the inferior oblique muscle on patients suffering from unilateral superior oblique palsy. METHODS Inferior oblique muscle graded recession and anteriorization were performed on twenty-two patients (22 eyes) with unilateral superior oblique palsy. The recession and anteriorization were matched to the degree of i...

A 53-year-old woman complaining of vertical diplopia, presented with a localized swelling in the right lower lid. Magnetic resonance imaging studies demonstrated a relatively well-defined mass in the inferior rectus with similar signal characteristics to the muscle. Excisional biopsy of the mass revealed granular cell tumor composed of S-100 positive cells with acidophilic granular cytoplasm an...

BACKGROUND We studied the incidence and clinical characteristics of persistent diplopia related to anaesthesia for cataract surgery in a general hospital. METHODS This was a retrospective review of anaesthesia for 3587 cataract surgeries. Of all the cases of diplopia referred to the ocular motility clinic after cataract surgery, those involving anaesthesia-related diplopia lasting longer than...

A 52-year-old woman underwent a secondary cosmetic blepharoplasty for repair of residual dermatochalasis. After this procedure vertical diplopia was noted. Ultrasound examination and the findings at operation were consistent with trauma to the inferior rectus muscle. We present this as an additional complication of cosmetic blepharoplasty.

The rectus extraocular muscle (EOM) pulleys constrain EOM paths. During visual fixation with head immobile, actively controlled pulleys are known to maintain positions causing EOM pulling directions to change by one-half the change in eye position. This pulley behavior is consistent with Listing's law (LL) of ocular torsion as observed during fixation, saccades, and pursuit. However, pulley beh...

OBJECTIVE The effect of radiotherapy on moderate and severe Thyroid associated ophthalmopathy (TAO) was evaluated by various objective and quantitative indexes including T2 signal intensity ratios of orbital MRI inferior rectus and ipsilateral temporal muscle (T2SIR), extraocular muscles (EOM) volume, and the degree of exophthalmos using clinical research with prospective, randomized, double bl...

musculocutaneous pedicled/ free flaps are an essential prerequisite for reconstructive surgery. amongst the trunk muscles commonly harvested for flaps, the trapezius and rectus abdominis provide satisfactory coverage for cranial and trunk defects. unilateral/ bilateral or partial congenital absence of trapezius muscle is well documented and may result in muscular imbalances compromising posture...
