Partial transplantation of the levator palpebrae superioris in superior rectus palsy.
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...
متن کاملSpecific force of the rat extraocular muscles, levator and superior rectus, measured in situ.
Extraocular muscles are characterized by their faster rates of contraction and their higher resistance to fatigue relative to limb skeletal muscles. Another often reported characteristic of extraocular muscles is that they generate lower specific forces (sP(o), force per muscle cross-sectional area, kN/m(2)) than limb skeletal muscles. To investigate this perplexing issue, the isometric contrac...
متن کاملLevator function in blepharoptosis surgery.
AIM To investigate the predictive value of levator function in the outcomes of surgeries using the anterior levator resection technique in patients with aponeurotic blepharoptosis. METHODS A retrospective analysis of 69 eyes of 65 patients who underwent anterior levator resection between 2005 and 2011 in the ophthalmology department of a tertiary care center was performed. Levator function wa...
متن کاملLevator ani function before and after childbirth.
OBJECTIVE To evaluate pelvic floor muscle strength before and after vaginal birth. DESIGN Prospective repeated measures study. SETTING Main district hospital. POPULATION Fifty-five women: 25 primiparae and 20 multiparae following vaginal birth, and 10 women following elective caesarean delivery as a control group. METHODS Pelvic muscle strength was evaluated by palpation, perineometry a...
متن کاملGraves' ophthalmopathy: V. Aetiology of upper eyelid retraction in Graves' ophthalmopathy.
The volume of the levator superior rectus muscle complex was determined from computed tomography scans of 152 orbits from 76 patients with Graves' ophthalmopathy. Clinically observed lid retraction and lid lag did not correlate with the levator/superior rectus muscle volume and did not correlate with limitation of vertical eye movements or inferior rectus muscle volume. These results do not sup...
