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...

purpose: to evaluate the clinical findings and surgical management of patients with congenital unilateral double elevator palsy (dep) or monocular elevation deficiency (med) methods: in a non-comparative interventional case series, 27 consecutive cases of dep were studied. hypotropia, elevation deficiency, and pseudoptosis were corrected by knapp or callahan procedure with or without inferior r...

The levator ani is vulnerable to injury during childbirth and effective surgical intervention requires full knowledge of the morphology and mechanical properties of the muscle structure. The shape of the levator ani and regional thickening during different levels of physiological loading can provide an indication of pelvic floor dysfunction. This paper describes a coupled approach for shape and...

OBJECTIVE This study was undertaken to develop and test a 3-dimensional (3D) color thickness mapping technique on levator ani imaged with magnetic resonance imaging (MRI). METHODS Supine MRI datasets from 30 women were studied: 10 asymptomatic, 10 with urodynamic stress incontinence, and 10 with pelvic organ prolapse. Levators were manually outlined, and thickness mapping applied. Three-dimen...

[Purpose] This study investigated the changes in pressure pain threshold of the upper trapezius, levator scapular, and rhomboid muscles during continuous computer work. [Subjects] Fourteen males and females aged 26-32 years, were recruited. [Methods] A dolorimeter pressure algometer was used to measure the pressure pain threshold of the upper trapezius, levator scapular, and rhomboid muscles, r...

Blepharoptosis (ptosis) is one of the most common eyelid disorders encountered in ophthalmology. A detailed history and exam are crucial in the evaluation of a patient presenting with ptosis. This provides the correct guidelines for surgical planning. The appropriate surgical technique is usually determined by the degree of ptosis and levator function. The surgeon should have an armamentarium o...

The Fasanella-Servat operation is much the simplest operation for ptosis and is useful for mild ptosis with good levator function. ' Fasanella and Servat described it as an excision of tarsoconjunctiva along with Muller's muscle and levator palpebrae superioris. However, histopathological examination of the excised tissue has later shown it to contain only tarsoconjunctiva and occasionally Mull...

Differences in eyelid structure are well described in the literature with respect to the Asian eyelid, but discussion of differences in eyelid structure between the other races is scarce. Most of the literature focuses on distinctions between “double” and “single” eyelids. Other clinical and surgical considerations are the presence of epicanthi and palpebral fissure slant. By understanding raci...
